Overview
XCM CNC is a Shenzhen UHMW CNC machining factory certified to ISO 9001 and IATF 16949. Qiaofeng 3016 large-travel milling and a Shenyang CK61125 CNC lathe support batch supply of large guide rails, liners, and wear-guidance structures. MOQ is one piece and standard lead time is 10-15 days. Repeat orders retain material-lot traceability and reusable process parameters. Before scheduling, engineering assesses warpage, low-speed cutting, and guide-surface protection before moving samples to batches.
Key Capabilities

- Tolerance: +/-0.05 mm standard; +/-0.01 mm selected critical features (by drawing review, geometry and creep behavior dependent)
- Surface Finish: Ra 3.2 um standard milled, Ra 1.6 um precision milled or turned (selected features by drawing review)
- GD&T: Flatness 0.05 mm, position 0.03 mm (selected hole groups), coaxiality and runout by drawing review (UHMW creep affects geometric stability)
- Max Size: Milling 3000 x 1600 x 1400 mm / Turning Dia. 1250 x 2000 mm
- Surface Treatment: Deburring, edge smoothing, low-friction prep or food-contact handling by drawing review
- Thread: M2-M220, NPT / BSP / G / PT (thread retention in UHMW requires load and wall-thickness review)
- Batch Range: 1 piece to repeat production; standard lead time 10-15 days
UHMW Large-Size Milling Capacity for Factory Supply Projects
Large UHMW wear parts are scheduled within 3000 x 1600 x 1400 mm milling travel and Dia. 1250 x 2000 mm turning. A Qiaofeng 3016-4A can machine 2600 mm guide rails and liners in one setup, reducing joining and secondary alignment. Panels over 1500 mm are reviewed for warpage and support spacing, using +/-0.05 mm standard tolerance and separated roughing and finishing.
UHMW Batch Material-Lot Traceability for Repeat Orders
Repeat orders link UHMW lot numbers to inspection records across batches. When natural, FDA-grade, or antistatic grades change, each incoming batch is marked separately and first-article process parameters and inspection datums are reused. Guides and liners receive +/-0.05 mm sampling, while critical holes use full 0.03 mm position inspection.
UHMW Thread and Mounting Features for Structural Wear Parts
UHMW structural parts can use M2-M220 threads and NPT/BSP mounting holes with thread-gauge verification. Thread retention is lower than metal and rigid engineering plastics, so inadequate wall thickness or high load triggers a note for metal inserts or through bolts. Counterbores begin at Dia. 2.0 mm and mounting-hole groups use 0.03 mm position.
UHMW Export Packaging and Surface Protection for Batch Shipment
Batch shipment includes flatness recheck, edge protection, and isolated export packing. FDA-grade food guide strips and large liners use protective film on Ra 1.6 um finished faces, with foam locating mounting holes and datum edges to prevent pressure marks. CMM, FAI, and material certificates travel with shipment and batch records remain available for repeats.

Applications
UHMW Conveyor Guides and Chain-Guide Supply Parts
Typical parts: Wear Guide Rail, Chain Guide, Slide Strip.
UHMW wear resistance and self-lubrication suit repeat supply of continuous-sliding guides. Material lot is tied to machining records; long parts receive stress relief after roughing before datum-edge finishing to reduce batch-to-batch straightness variation.
Food Guide Strips and Scraper Batch Supply
Typical parts: Guide Strip, Sorting Scraper, Rail Pad.
FDA-grade UHMW suits food-line contact parts. Each batch can include material certificate and food-grade declaration, guide edges can ship at Ra 1.6 um precision milling, and mounting holes receive individual go/no-go gauge checks.
Bulk Conveying Liners and Wear-Liner Supply Parts
Typical parts: Hopper Liner, Chute Liner, Wear Liner Block.
UHMW low friction and extreme wear resistance suit bulk-conveying liners. Large liners use whole-sheet machining within 3000 x 1600 mm travel, with batch scheduling grouped by incoming sheet thickness to reduce thickness and flatness variation.
Fender Pads and Buffer Slide Supply Parts
Typical parts: Fender Pad, Buffer Slide Block, Slipway Pad.
UHMW impact resistance and low friction suit dock fenders and marine buffer parts. Large buffers receive flatness recheck before shipment, foam corner location, and protected mounting faces; cartons or wood crates are selected for DHL, FedEx, or sea freight.
Why Choose Us
Complete Quality System and Equipment Coverage
The factory organizes quality processes around ISO 9001, ISO 13485, IATF 16949, and GJB9001C, using DMG, Mazak, Matsuura, Brother, and other equipment for large UHMW wear parts, guide parts, and low-friction sliding parts. Drawing review for conveyor guides, liners, food-contact parts, and large wear plates confirms warpage risk, low-speed cutting, and dimensional-stabilization planning.
Broad Size Coverage
Machining covers small connectors through large structures, including UHMW guide strips, wear slides, scrapers, and low-friction guards, as well as large liners, conveyor guides, and dock buffer panels. Three-axis travel reaches 3000 x 1600 x 1400 mm and turning diameter reaches 1250 mm; fixturing, warpage, stress release, and service temperature are confirmed from the drawing.
Tiered Equipment Strategy for Low-Cost CNC Machining, Quality-Assured Production
XCM CNC uses CNC equipment from mainland China, Taiwan, Japan, and Europe or the United States. Large-face roughing and regular-hole machining can use domestic long-travel machines, while precision holes and mating faces use Brother, Matsuura, DMG, or Mazak equipment. Equipment is matched to drawing tolerances to control cost without losing required precision.
UHMW Batch Scheduling and Delivery Rhythm
Large UHMW guides, liners, and strips are scheduled through roughing, stress release, finishing, and reinspection in a 10-15 day cycle. Repeat orders retrieve prior parameters and datums, while sheet specification and machine matching confirmed on the first order are reused.
UHMW Export Packing and Surface Protection
Flatness recheck, corner protection, and isolated packing are completed together before shipment. Food-contact and large wear plates use film or foam selected for key-face position; first articles fix the packing standard and later batches follow it.
FAQ
What UHMW parts does your factory usually machine for supply?
Common supply parts include conveyor guides, chain guides, wear liners, food-line strips, sorting scrapers, and dock slipway pads. The factory covers large wear parts with 3000 x 1600 mm milling travel and Dia. 1250 mm turning; grade, key-face tolerance, and packing protection are confirmed before batch supply.
How does UHMW compare with Nylon or POM on wear parts?
UHMW is usually considered first for extreme wear, self-lubrication, and large sliding parts. Nylon or POM is often better where rigidity, thread retention, or dimensional stability matter more. Final selection depends on load, temperature, and fit.
How do you keep batch consistency for repeat UHMW orders?
Repeat orders use first-article process parameters and inspection datums. Every incoming lot is separately marked and linked to machining records; critical dimensions receive CMM sampling or full inspection, while sheet grouping and consistent fixturing control batch variation.
What is the standard lead time for batch UHMW parts?
Standard lead time is 10-15 days and samples take 3-7 days, assessed by part size, structure, and quantity. Large liners that need stress release after roughing receive a separate schedule note.
What file formats do you accept for UHMW part quotes?
STEP, IGES, STP, DWG, and dimensioned PDF are accepted. Provide drawings, UHMW grade, tolerances, quantity, and service environment; food-grade and large-liner projects should also mark batch and packing requirements.
How do you pack and ship large UHMW parts for export?
Large parts use foam with cartons or wooden crates, and key machined faces receive film or foam isolation. DHL, FedEx, UPS, and sea freight are available, with reinforcement selected by size, weight, and acceptance standard.
