UHMW CNC Machining Services for Wear Strips and Guide Rails
UHMW CNC machining is a strong choice for low-friction, abrasion-resistant plastic parts used in sliding, guiding and conveying applications. Baosheng machines custom UHMW-PE and PE1000 wear strips, guide rails, conveyor guides, liners, slide blocks, rollers and bushings from customer drawings.
Parts We Machine
UHMW-PE Machined Parts for Sliding and Conveyor Applications
Most UHMW machining requests are not general plastic parts. They are wear components that must slide smoothly, resist abrasion and fit existing equipment.
UHMW Wear Strips and Guide Rails
Used for conveyor lines, chain guides, belt guides, product guides and packaging equipment.
- Wear strips
- Guide rails
- Conveyor guides
UHMW Liners, Slide Blocks and Wear Pads
Used where sliding contact, impact or abrasive material can wear metal or other plastics.
- Chute liners
- Slide blocks
- Wear pads
UHMW Rollers, Bushings and Spacers
Used when low friction, practical clearance and quiet movement are more important than high stiffness.
- Rollers
- Bushings
- Spacers
Material Grades
UHMW Material Grades: Natural, Black, Food-Grade and PE1000
The right grade depends on wear condition, color, food-contact needs, static control, friction, cost and documentation. If your drawing specifies PE1000, UHMW-PE 1000, TIVAR-type material or an approved equivalent, include that note in the RFQ.
Natural UHMW
Common for wear strips, liners, guide rails and general low-friction parts.
Black UHMW
Used for machine parts, visible guides and replacement wear components.
Food-Grade UHMW
Reviewed for conveyor guides, scraper blades and clean-contact components.
Anti-Static / ESD UHMW
Used when conveying or packaging equipment needs specified electrical behavior.
Oil-Filled UHMW
Reviewed for low-friction sliding parts and guide components.
PE1000 / TIVAR-Type
Used when the drawing calls out PE1000 or approved equivalent requirements.
Material Fit
UHMW vs Nylon, POM, PTFE and PEEK
Choose UHMW when abrasion resistance, low friction and impact behavior matter more than stiffness or very tight mechanical features.
| Material | Better For | Review Point |
|---|---|---|
| UHMW | Wear strips, guide rails, liners and sliding parts | Best when low friction and abrasion resistance are the main goals. |
| POM / Delrin | Precision plastic parts, stable bores and mechanical features | Often better when tight dimensions are more important. |
| Nylon | Higher stiffness and load-bearing plastic parts | Review moisture absorption and application environment. |
| PTFE | Very low friction or chemical-resistant parts | Better for chemical exposure and sealing behavior. |
| PEEK | High-temperature and high-performance engineering parts | Higher cost, but better for demanding environments. |
Machining Review
UHMW Machining Tolerances, Burrs and Long-Part Flatness
UHMW is softer and more flexible than metal or rigid engineering plastics. Good drawings keep critical dimensions clear and do not force metal-like tolerances across long or flexible sections.
Practical Tolerance Review
Long strips, rails, liners and thin parts should be reviewed for straightness, flatness, installation movement and inspection method.
Burr and Fuzz Control
UHMW can leave soft burrs or fuzzy edges. Mark sliding faces, product-contact edges, food-contact edges and hand-contact edges.
Hole, Slot and Countersink Fit
Mounting holes, slots and countersinks should match the installation method, screw clearance and expected part movement.
Round Part Clearance
Rollers, bushings and sleeves should be reviewed for shaft fit, bore stability, chamfers and operating clearance.
Drawing Notes
Design Notes for UHMW Wear Strips and Guide Rails
The fastest UHMW quotes usually come from drawings that explain how the part is used, not only its outside dimensions.
Mark the wear face, sliding direction and product-contact edge.
Show hole pattern, slotted holes, countersinks and mounting hardware needs.
State natural, black, food-grade, anti-static, oil-filled UHMW or PE1000.
Limit tight tolerances to critical features and show them on the PDF drawing.
Tell us the mating material, load, speed, cleaning method and operating environment when available.
For long UHMW parts, include packing or shipping notes when straightness is important.
Customer FAQ
UHMW CNC Machining FAQs
What is UHMW or UHMW-PE?
UHMW means ultra-high molecular weight polyethylene. It is used for low-friction, abrasion-resistant and impact-resistant wear parts.
Is UHMW good for CNC machining?
Yes. UHMW can be milled, routed, drilled and turned into custom wear parts, but burrs, flexibility and practical tolerance limits should be reviewed before production.
Can UHMW hold tight tolerances?
UHMW can hold useful functional tolerances, but it is not the best material for very tight bores or rigid precision features. For those parts, POM or Delrin may be better.
Does UHMW leave burrs or fuzzy edges?
It can. Mark burr-free edges, sliding surfaces and product-contact areas so edge cleanup can be reviewed before quoting.
What files are needed for a UHMW quote?
Send 3D CAD files and PDF drawings with grade, quantity, wear surface, hole pattern, sliding direction, mating material and inspection requirements.

What to Send for a UHMW Machining Quote
Send CAD files and drawings for UHMW wear strips, guide rails, conveyor guides, liners, slide blocks, rollers, bushings or replacement wear parts. Clear wear and installation notes help us quote faster and reduce back-and-forth communication.
