CNC Lathe Machine Buyer Guide<\/h2>\n

A real CNC lathe machine<\/a> factory in China controls its own casting supply, maintains an in-house scraping and assembly floor, and can produce documented geometric accuracy reports from laser interferometer and ball bar testing. Trading offices rent showroom space and ship machines they never assembled\u2014buyers pay 8\u201315% more for identical specifications while losing direct access to spare parts and application engineering.<\/p>\n

The rest of this page breaks down seven verification points: foundry or casting source documentation, assembly floor evidence, metrology records, factory acceptance test protocols, payment structure risk signals, after-sales engineering capability, and how each factor affects total cost of ownership across a 10-year machine life.<\/p>\n

Casting Source and Bed Construction<\/h3>\n

Genuine builders either operate a captive foundry or hold long-term contracts with HT250 or HT300 resin sand casting suppliers. A 500 mm swing flat bed CNC lathe should carry roughly 3,200\u20134,500 kg net weight; slant bed machines in the 8-inch chuck class typically run 3,500\u20135,000 kg. Ask for the casting grade certificate\u2014HT300 offers 30% better damping than HT250\u2014and confirm stress relief duration. Two-stage aging, 6 months natural plus furnace normalization, prevents 0.05 mm\/300 mm geometric drift in the first two years.<\/p>\n

Assembly Floor and Hand Scraping<\/h3>\n

Trading offices display machines under plastic sheets in rented warehouses. Real factories show scraping marks on guideway mating surfaces, typically 10\u201316 contact points per 25 mm \u00d7 25 mm on box way machines. Linear roller guide machines (HIWIN or PMI) skip hand scraping but require precision-ground mounting surfaces to \u00b10.01 mm\/1000 mm. Request time-stamped photos of your specific serial number during spindle run-in\u2014minimum 4 hours at 3,500 rpm for a 7.5 kW A2-6 spindle.<\/p>\n

Metrology Records That Matter<\/h3>\n

Laser interferometer positioning accuracy should read \u22640.020 mm\/300 mm for standard class, \u22640.010 mm\/300 mm for precision class. Ball bar circularity on a 150 mm radius test: \u22640.015 mm for job shop grade, \u22640.008 mm for tooling work. Ask for the actual report with machine serial number, date, and technician signature\u2014not a generic template. Repeatability per ISO 230-2: \u00b10.006 mm for 8-inch chuck machines, \u00b10.003 mm for 12-inch and above.<\/p>\n

Factory Acceptance Test Protocol<\/h3>\n

A proper FAT includes: 72-hour continuous run at 80% rated spindle load; thermal growth compensation check (spindle centerline drift \u22640.010 mm after 4 hours); and actual cutting test on 45# steel or 304 stainless. Reject any supplier who offers only “visual inspection” or refuses witness testing. For slant bed CNC lathes with 8-inch chuck, specify bar capacity\u201452 mm through-hole on A2-6 spindles, 65 mm on A2-8\u2014and confirm C-axis indexing accuracy \u00b10.01\u00b0 if live tooling is included.<\/p>\n

Payment Structure and Risk Signals<\/h3>\n

Trading offices typically demand 100% TT before shipping. Established factories accept 30% deposit, 70% against copy of BL, or letter of credit for orders above $80,000. Red flags: refusal to accept third-party inspection, no VAT invoice from the actual manufacturer, or quotes 20% below market without specification variance. Current FOB Shanghai indicative ranges: flat bed CNC lathe 500 \u00d7 1,000 mm with GSK 980TDi, $18,000\u2013$24,000; slant bed 8-inch chuck with FANUC 0i-TF, $35,000\u2013$48,000; 12-inch chuck slant bed with Siemens 828D and 12-station turret, $55,000\u2013$72,000.<\/p>\n

After-Sales Engineering Capability<\/h3>\n

Verify: staffed service office in your region or committed 48-hour response time; spare parts inventory held domestically (turret index fingers, spindle bearings, servo motors); and remote diagnostics capability through control system native function\u2014FANUC FOCAS, Siemens Access MyMachine. Ask for three reference installations in your industry, same machine class, operating minimum 18 months. A factory that built the machine can dispatch a spindle engineer; a trader forwards your complaint to a WeChat group.<\/p>\n

Flat Bed CNC Lathe Economy Class<\/h3>\n

This is the machine most first-time CNC buyers from Africa, Southeast Asia and South America encounter. A 400 mm swing by 1000 mm between centres unit with GSK 980TDi control, 7.5 kW spindle and HIWIN linear guides ships in a 40-foot container at roughly 2600 kg net weight. The factory price at FOB Qingdao typically falls between $18,000 and $28,000 depending on chuck size (200 mm or 250 mm hydraulic), whether tailstock is included, and whether the builder uses HT250 or HT300 casting. Lead time runs 25\u201335 days for standard configurations. What this machine cannot do: maintain tight tolerances on interrupted cuts or heavy roughing passes. The linear guide version lacks the damping mass of box ways, and the 2500 rpm maximum spindle speed limits productivity on small-diameter aluminium work. Buyers are usually small job shops, municipal technical schools, or agricultural repair workshops that need to step up from manual lathes without operator retraining. The real supplier qualification task here is verifying the casting source\u2014many trading offices source HT250 beds from small foundries with inconsistent cooling, leading to warping six months after installation.<\/p>\n

Flat Bed CNC Lathe Heavy Duty Class<\/h3>\n

When a machine shop in the Middle East or Eastern Europe repairs oil drilling stems or wind turbine main shafts, this is the configuration specified. A 630 mm swing by 3000 mm length machine with 130 mm spindle bore, FANUC 0i-TF control and hardened box ways on all axes weighs approximately 8500 kg and requires a 12-tonne forklift or overhead crane for unloading. The 22 kW spindle at 1500 rpm delivers high torque at low speed for alloy steel roughing. Rapid traverse stays modest at 6\u20138 m\/min because mass and accuracy take priority over speed. Positioning accuracy of \u00b10.01 mm and repeatability of \u00b10.005 mm are achievable only after proper foundation and levelling\u2014builders who skip scraping the box way mating surfaces will not hit these numbers regardless of control brand. Lead time extends to 45\u201360 days due to casting stress relief cycles (minimum 30 days for HT300 beds). Price drivers: spindle bore size (105 mm vs 130 mm), whether the bed is one-piece or joined, and whether the builder performs laser interferometer verification on X and Z axes. What it cannot do: compete with slant bed machines on cycle time for small batch work. The heavy casting and slow rapids make it inefficient for parts under 100 mm diameter.<\/p>\n

Slant Bed CNC Lathe Two-Axis Turning Center<\/h3>\n

This class dominates automotive supply chains and high-volume hydraulic fitting production. The 45\u00b0 bed angle provides chip gravity discharge and ergonomic operator access, while linear roller guides permit 20\u201330 m\/min rapid traverse. A typical 250 mm swing machine with 65 mm bar capacity, FANUC 0i-TF Plus, 8-station or 12-station turret, and 7.5 kW spindle at 4500 rpm weighs 4200 kg and occupies 2.8 m \u00d7 1.6 m floor space. Positioning accuracy \u00b10.005 mm and repeatability \u00b10.003 mm are standard when the builder ball-bar tests each machine before dispatch. Price at FOB China runs $32,000\u2013$55,000 depending on turret type (electric vs hydraulic), whether C-axis preparation is included, and whether the spindle uses A2-5 or A2-6 nose configuration. Lead time is 30\u201340 days for standard builds. Buyers are tier-two automotive suppliers, valve manufacturers, and job shops serving the construction equipment aftermarket. What it cannot do: mill flats or drill cross-holes efficiently\u2014that requires live tooling and Y-axis travel, which this base configuration lacks. The supplier qualification focus shifts to turret sourcing (imported vs domestic tool disc), whether the linear guides are genuine HIWIN\/PMI or unbranded copies, and whether the builder maintains laser interferometer records for each serial number.<\/p>\n

Slant Bed CNC Lathe Turn-Mill with Y-Axis and Sub-Spindle<\/h3>\n

This is the configuration that separates actual machine builders from assembly shops. A 260 mm swing turn-mill with \u00b135 mm Y-axis travel, C-axis interpolation, 12-station turret with live tooling, sub-spindle, and FANUC 31i-B control weighs 7800 kg and requires precise thermal management. The 11 kW main spindle at 6000 rpm and 5.5 kW sub-spindle at 5000 rpm enable complete machining of complex aerospace or medical parts in a single setup. Positioning accuracy of \u00b10.004 mm demands that the builder scrape the slant bed to the spindle within 0.01 mm over 500 mm, then verify with ball bar and laser interferometer. Machine price ranges $75,000\u2013$140,000 depending on sub-spindle specification, live tooling rpm (4000 vs 8000), and whether the control includes full 5-axis simultaneous capability. Lead time stretches to 60\u201390 days. Buyers are medical device contract manufacturers, aerospace tier-one suppliers, and precision automotive component houses. What it cannot do: compete on price with simple two-axis lathes for straight turning work\u2014the sub-spindle, Y-axis mechanism and thermal compensation add cost and complexity that recover only when part families justify the capital outlay. Supplier qualification here is critical: ask for the geometric accuracy report including spindle runout (target under 0.003 mm), turret repeatability, and documented thermal growth test after 4-hour warm-up.<\/p>\n

Vertical CNC Lathe<\/h3>\n

VTLs occupy a niche that horizontal lathes cannot serve: heavy, short workpieces where gravity assists clamping and chip removal. A 1250 mm table diameter machine with 4000 kg table load capacity, 30 kW main motor, and FANUC 0i-TF control uses a single-column or double-column HT300 casting weighing 22000 kg. Table speed of 200 rpm with 3200 Nm torque handles cast iron brake discs and pump housings. Positioning accuracy \u00b10.008 mm is achievable with cross-roller bearings on the table and box way construction on the ram. Price drivers: single vs double column, table bearing diameter (determines radial load capacity), and whether the builder includes automatic tool measurement. FOB pricing runs $85,000\u2013$180,000; lead time 60\u201375 days due to large casting procurement and lengthy stress relief. Buyers are wind turbine component manufacturers, railway wheel producers, and mining equipment rebuilders. What it cannot do: handle long shafts\u2014the vertical configuration limits workpiece height, and the ram deflection on overhang becomes significant above 600 mm. Foundation requirements are substantial: a 250 mm reinforced concrete pad with anchor bolts, versus 150 mm for horizontal lathes of equivalent weight class.<\/p>\n

Swiss-Type CNC Lathe<\/h3>\n

Swiss-type machines represent a distinct architecture where the bar feeds through a guide bushing while the headstock slides on Z-axis ways, maintaining tool support within 2 mm of the cut at all times. A 20 mm maximum bar capacity machine with 5 axes, FANUC 32i-B control, 3.7 kW main spindle at 12000 rpm and 2.2 kW sub-spindle at 8000 rpm weighs 3200 kg and occupies 2.2 m \u00d7 1.4 m. Positioning accuracy \u00b10.003 mm and surface finishes under Ra 0.4 \u00b5m are achievable with quality guide bushings and thermal stability systems. Price ranges $65,000\u2013$120,000 for configurations with backworking attachment, chip conveyor, and oil mist collector. Lead time 45\u201360 days; many builders source critical components (guide bushings, collet systems) from Japan or Switzerland, creating supply chain dependencies. Buyers are medical implant manufacturers (bone screws, dental abutments), electronics connector houses, and precision watch component suppliers. What it cannot do: accept cast or saw-cut bar with diameter variation over 0.05 mm\u2014the guide bushing principle requires ground bar stock. It also cannot economically produce parts longer than 3\u20134 times the bar diameter. Supplier qualification must address: whether the builder manufactures its own spindles or sources from Setco or Weifu, guide bushing material (tungsten carbide vs ceramic for abrasive alloys), and whether thermal compensation is standard or optional.<\/p>\n

How to Read Each Line of the Specification Sheet<\/h3>\n

Working Range and Travels<\/strong><\/p>\n

The X-axis travel tells you how far the tool post moves perpendicular to the spindle centerline. On a 500 mm swing lathe, 250 mm X-travel means you can turn a part up to 500 mm diameter with the tool on center. The Z-axis travel is your maximum part length between chuck face and tailstock or tailstock center. Add 100\u2013150 mm to the stated Z-travel for tooling clearance and part overhang. A machine rated at 1000 mm Z-travel handles roughly 850\u2013900 mm of actual turned length.<\/p>\n

Max Turning Diameter and Length<\/strong><\/p>\n

These are the hard limits set by bed width, carriage height, and tailstock travel. Check whether the max diameter is over-bed or over-carriage. Over-bed diameter is larger and rarely usable for actual cutting. Over-carriage or over-swing diameter is what matters for your parts. For long shafts, verify that the tailstock quill diameter and taper (typically MT3, MT4, or MT5) match your center hole sizes.<\/p>\n

Spindle Speed and Power<\/strong><\/p>\n

Higher rpm suits small diameters and aluminum. Lower rpm with higher torque handles large steel forgings. The 7.5 kW entry-level spindle peaks at 3500 rpm but torque drops above 2500 rpm. The 22 kW A2-8 spindle at 2000 rpm delivers constant torque from 200\u20131200 rpm, which is where heavy roughing happens. Check the torque curve, not just the kW rating. A 15 kW spindle with a 1:4 gear reduction often out-torques an 11 kW direct-drive spindle below 800 rpm.<\/p>\n

Spindle Taper and Chuck Size<\/strong><\/p>\n

A2-5, A2-6, and A2-8 are short taper nose standards. Larger numbers mean larger flange diameters and higher torque capacity. An 8-inch chuck on A2-5 is the practical limit; 10-inch on A2-6 is standard; 12-inch on A2-8 handles 250 mm billets. The spindle bore diameter determines maximum bar capacity for automatic feeding. 52 mm bore passes 50 mm hex bar. 105 mm bore passes 102 mm round bar. If you buy hydraulic bar feeders later, the bore must match.<\/p>\n

Guideway Type<\/strong><\/p>\n

Hardened box ways ( scraped Turcite-B on cast iron ) damp vibration and carry heavy interrupted cuts. Linear roller guides (HIWIN HG series or PMI MSA series) enable 24\u201330 m\/min rapids and tighter positioning but have lower shock resistance. For general job shop work with mixed batch sizes, linear guides reduce non-cutting time. For foundry-facing, roll-turning, or heavy alloy steel, box ways last longer and require less rail replacement.<\/p>\n

Rapid Traverse and Feed Rates<\/strong><\/p>\n

Rapid traverse is the turret’s positioning speed between cuts. 30 m\/min Z-axis rapid on a mid-range machine means the turret crosses 1000 mm in 2.5 seconds. Actual cutting feeds are 0.05\u20132 mm\/rev, so rapid speed only affects cycle time on short parts with many tool changes. For long shafts, rapid speed matters less than steady feed rate and chip control.<\/p>\n

Positioning Accuracy and Repeatability<\/strong><\/p>\n

Positioning accuracy ( \u00b10.010 mm ) is where the machine thinks it is versus where it actually is. Repeatability ( \u00b10.004 mm ) is whether it returns to the same spot after a full traverse. Repeatability matters more for batch consistency. Positioning accuracy matters for first-off parts and when you transfer programs between machines. Ask for the laser interferometer report: X-axis straightness, Z-axis pitch error compensation, and backlash values at multiple points along the travel.<\/p>\n

Tool Magazine and Change Time<\/strong><\/p>\n

Turret index time is 0.3\u20130.6 seconds per station on servo-driven turrets. Hydraulic turrets are slower at 0.8\u20131.2 seconds and require periodic seal maintenance. Live tooling on milling-capable turrets adds BMT55 or BMT65 tapers and 3\u20137.5 kW driven tools. Check whether live tooling is standard or requires a factory-built option\u2014retrofitting later is often impossible.<\/p>\n

Control System<\/strong><\/p>\n

GSK 980TDi and KND K2000Ti are Chinese systems with FANUC-compatible G-code. They cost 40\u201350% less than FANUC but have smaller installed bases outside China. FANUC 0i-TF and Siemens 828D are the global standards. FANUC dominates Southeast Asian and North American job shops; Siemens dominates Eastern Europe and technical training centers. Syntec is common on Taiwanese-style slant-bed machines. Mitsubishi M80 is rare on lathes but appears on Japanese-built turning centers. Control choice affects spare parts availability, operator training cost, and resale value.<\/p>\n

Supply Voltage and Connected Load<\/strong><\/p>\n

Chinese-built CNC lathes ship at 380V 3-phase 50Hz. For 220V 60Hz regions (North America, parts of South America, Philippines), you need a step-up transformer or a factory-ordered 220V\/60Hz spindle motor and control voltage. The transformer adds 8\u201312% to landed cost and 150\u2013300 kg to shipping weight. Verify whether the control cabinet includes an isolation transformer for voltage stabilization.<\/p>\n

Machine Weight and Floor Space<\/strong><\/p>\n

Weight correlates with rigidity. A 500 mm swing lathe at 2200 kg uses lighter castings and may need bolt-down for heavy cuts. The same swing at 4500 kg has thicker walls, wider box ways, and better chatter resistance. Floor space must include operator access: 1000 mm front clearance for chuck loading, 600 mm rear clearance for chip conveyor and coolant tank service.<\/p>\n

Price Drivers and Lead Time<\/h3>\n

Control System Premium<\/strong><\/p>\n

FANUC 0i-TF adds $4,000\u2013$6,000 over GSK on a mid-range lathe. Siemens 828D adds $5,000\u2013$7,000. FANUC 0i-TF Plus with 200-block lookahead and AI contour control adds $8,000\u2013$10,000. This is the single largest optional cost after the base machine.<\/p>\n

Spindle and Chuck Upgrades<\/strong><\/p>\n

Moving from 8-inch hydraulic to 10-inch hydraulic chuck adds $1,200\u2013$1,800. A2-6 spindle over A2-5 adds $2,500\u2013$3,500 in bearing and shaft costs. Through-spindle coolant (70 bar) adds $3,000\u2013$4,500 and requires a high-pressure pump and rotary union.<\/p>\n

Guideway and Scale Feedback<\/strong><\/p>\n

Linear guides over box ways add $2,000\u2013$3,500. Linear scale feedback (closed-loop positioning, mandatory for some aerospace work) adds $4,000\u2013$6,000 per axis and requires Heidenhain or Fagor glass scales with sealed read heads.<\/p>\n

Lead Time Structure<\/strong><\/p>\n

Standard configurations from established builders: 25\u201335 days production. Custom spindle bore, special voltage, or third-party control integration: 45\u201360 days. Peak months (March\u2013May pre-Canton Fair, September\u2013October pre-IMTS) extend by 10\u201315 days. Sea freight to Southeast Asian ports: 12\u201318 days. To Middle East (Jebel Ali): 18\u201325 days. To East Africa (Mombasa): 25\u201335 days. To South America East Coast (Santos): 35\u201345 days.<\/p>\n

How to Verify a Real Builder from a Trading Office<\/h3>\n

Foundry or Documented Casting Source<\/strong><\/p>\n

Ask for the casting grade certificate: HT250 for entry-level beds, HT300 for mid-range and above. HT300 has 300 MPa tensile strength versus 250 MPa and better damping. Some builders use Meehanite-processed castings with flake graphite structure for heavy cuts. A trading office cannot produce this document; they forward what the factory gives them, often without understanding it. Request photos of the casting storage yard with machined beds in raw finish, not painted.<\/p>\n

Assembly Floor and Scraping Records<\/strong><\/p>\n

Precision lathe beds are hand-scraped to 8\u201312 contact points per 25 mm \u00d7 25 mm on the guideway mounting surfaces. Ask for photos of the scraping floor with scrapers, blue dye, and surface plates. A real builder keeps these records for 5\u20137 years. The scraping pattern should be visible even under Turcite or guideway covers.<\/p>\n

Laser Interferometer and Ball Bar Records<\/strong><\/p>\n

Factory acceptance test (FAT) requires laser interferometer measurement per ISO 230-2 or GB\/T 17421.2. Ask for the raw data file, not a summary. Renishaw XL-80 or API XD laser systems produce traceable reports. Ball bar testing (Renishaw QC20-W) checks circular interpolation and servo tuning mismatch. A 150 mm ball bar test at 1000 mm\/min feed should show roundness under 0.015 mm for entry-level, under 0.010 mm for mid-range.<\/p>\n

Geometric Accuracy Report<\/strong><\/p>\n

The report covers: spindle runout (test bar at 300 mm, 0.010 mm max); bed straightness (0.02 mm per 1000 mm); parallelism of spindle axis to Z-axis movement (0.02 mm per 300 mm); perpendicularity of turret face to spindle axis (0.015 mm). Each item should have measured values, tolerance limits, and inspector signature with date.<\/p>\n

Payment Structure as Signal<\/strong><\/p>\n

Trading offices often demand 30% T\/T advance, 70% against copy of B\/L\u2014standard but risky if they have no factory leverage. Established builders accept 30% advance, 65% after FAT photos or video confirmation, 5% after installation. Letters of credit (L\/C at sight) are accepted by builders with 5+ years export history; trading offices often refuse L\/C due to bank collateral requirements.<\/p>\n

After-Sales Engineering Capability<\/strong><\/p>\n

Ask for the service engineer’s passport copy and visa history. A builder with Southeast Asian or Middle Eastern installations can show entry stamps. Verify whether they stock servo motors, drives, and ball screws in regional warehouses or only ship from China. Response time commitment should be in the contract: 48-hour remote diagnosis, 7-day on-site arrival for critical failures.<\/p>\n

Trade Terms and Export Documentation<\/h3>\n

FOB, CIF, CFR, EXW<\/strong><\/p>\n

EXW (Ex Works) means you arrange everything from the factory gate. FOB (Free On Board) includes factory loading and China port export clearance; you pay ocean freight and insurance. CFR (Cost and Freight) includes ocean freight to your port; risk transfers at ship’s rail in China. CIF (Cost, Insurance, Freight) adds marine insurance; still your responsibility to unload and clear customs. For CNC lathes over 3000 kg, CIF is common because the builder has freight forwarding relationships for heavy machinery. For single small lathes, FOB saves 5\u20138% if you have your own freight forwarder.<\/p>\n

Payment Terms<\/strong><\/p>\n

T\/T (telegraphic transfer) is standard: 30% deposit, balance before shipment or against documents. L\/C at sight adds $400\u2013$800 in bank charges but protects against non-shipment. For orders above $80,000, some builders accept 180-day usance L\/C with bank guarantee. Avoid 100% advance payment for first orders.<\/p>\n

HS Code and Customs<\/strong><\/p>\n

CNC lathes fall under HS 8458.11 (horizontal lathes, numerically controlled) or 8458.91 (other lathes, numerically controlled). Duty rates vary: 0% within ASEAN under China-ASEAN FTA with Form E certificate; 5\u20138% in Middle Eastern GCC countries; 0\u20133.5% in most African countries under GSP. The packing list must match the machine nameplate, motor ratings, and control serial numbers.<\/p>\n

CE Marking and Documentation<\/strong><\/p>\n

CE marking on Chinese-built lathes covers the Machinery Directive 2006\/42\/EC and EMC Directive 2014\/30\/EU. Request the EC Declaration of Conformity with the notified body number if third-party assessment was used. Many Chinese builders self-declare CE; this is legal for most CNC lathes but requires technical file availability. The CE plate should be fixed to the machine column with builder name, address, year of manufacture, and serial number.<\/p>\n

Certificate of Origin and Packing<\/strong><\/p>\n

The certificate of origin (CO) is issued by China Council for the Promotion of International Trade (CCPIT) or local customs. For FTA benefits, request Form E (ASEAN), Form A (GSP countries), or specific bilateral forms. Packing for ocean shipment: vacuum-sealed plastic, plywood case with IPPC-treated wood marking, desiccant packs, and rust-preventive oil on unpainted surfaces. Total packed weight is 15\u201325% above net machine weight due to crate and foundation bolts.<\/p>\n

Unloading and Installation<\/strong><\/p>\n

A 4500 kg mid-range lathe requires a 5-tonne forklift or 3-tonne crane with spreader bar. The crate is 2200 mm \u00d7 1800 mm \u00d7 2100 mm\u2014check door widths and ceiling heights. Foundation bolts (M16 or M20, 8\u201312 pieces) set in epoxy grout or lead wedges. Levelling to 0.05 mm\/m using precision level on the bed ways. Full installation and training: 3\u20135 days for standard lathe, 7\u201310 days for Y-axis mill-turn with live tooling. Spare parts to stock initially: turret index pins, chuck jaws, coolant pump seals, and one set of axis servo motor brushes or encoder batteries.<\/p>\n

These bands assume standard configuration without optional part catchers, bar feeders, or automatic tool presetters. A Fanuc or Siemens control typically adds 8,000\u201315,000 USD over a domestic Chinese control on the same iron. Prices move with currency, steel casting costs, and sea freight indices.<\/p>\n

What the Factory Price Actually Covers<\/h3>\n

A CNC lathe machine<\/a> supplier and factory in China structures cost differently than a trading office reselling someone else’s build. The factory’s internal cost stack, expressed as approximate shares of a mid-range slant bed machine with Siemens 828D control, looks like this:<\/p>\n
