This precision slider block is fully CNC machined from premium POM (polyoxymethylene / acetal & Delrin®-grade), a crystalline engineering thermoplastic prized for its excellent balance of stiffness, toughness and low-friction performance. Every block is milled, drilled and finished on high-speed CNC centres, then inspected against a controlled tolerance band to guarantee repeatable, wobble-free sliding.
Starting from the machined material itself, the design takes full advantage of POM's natural lubricity, dimensional stability and fatigue resistance — making the block ideal for linear guides, guide rails, feed mechanisms and wear pads where metal parts would need frequent greasing or would corrode.
We machine the slider block from virgin POM (acetal homopolymer/copolymer), available in natural, black and custom colours. The typical key properties below define why POM is the material of choice for precision sliding components:
| Property | Value (typical) | Benefit for the slider |
|---|---|---|
| Density | 1.41 – 1.43 g/cm³ | Lightweight yet rigid block |
| Tensile strength | 60 – 70 MPa | Withstands cycling loads |
| Coefficient of friction (steel) | 0.15 – 0.35 | Smooth, low-friction sliding |
| Water absorption (24 h) | ≈ 0.2 % | Excellent dimensional stability |
| Continuous service temperature | −40 °C to +90 °C | Wide operating window |
| Hardness (Rockwell M) | ≈ 92 | Good wear and scratch resistance |
| Colour | White / Black / Custom | Matched to your equipment |
The figures below are reference / estimated dimensions for the standard model shown. Slider blocks are made to order, so all sizes can be customised to your drawing or sample.
| Item | Estimated size | Note |
|---|---|---|
| Overall length (L) | 50 mm | Adjustable |
| Overall width (W) | 30 mm | Adjustable |
| Overall height (H) | 20 mm | Adjustable |
| Guide / slot width | 10 – 12 mm | Matched to rail |
| Mounting hole diameter | φ 5 mm (M5) | Threaded inserts optional |
| Hole pitch | 35 × 18 mm | Custom hole patterns |
| Machining tolerance | ±0.02 mm | Critical fit faces |
| Surface roughness | Ra 0.8 – 1.6 µm | Polished sliding face |
Our POM slider workshop combines CNC milling, turning, drilling and precision finishing under one roof. Because plastic behaves very differently from metal, we use purpose-selected cutters, sharp geometries and controlled feed rates to avoid melting, burrs and internal stress.
| Process | Capability | Applied to the slider |
|---|---|---|
| CNC milling | 3 / 4 / 5-axis | Guide slot, pockets, radii |
| CNC turning | φ1 – φ300 mm | Bushing-style features, steps |
| Precision drilling | ±0.02 mm position | Mounting holes, dowel fits |
| Deburring & chamfering | All edges | Snag-free assembly |
| Surface finishing | Polished / sanded | Low-friction sliding face |
| QC inspection | CMM / calipers / gauges | 100% key-dimension check |
Key machining highlights that give the block its precision feel:
POM's natural lubricity lets the slider glide smoothly with minimal greasing, reducing maintenance and contamination.
Dense, hard machined surface resists abrasion, keeping the sliding clearance stable over millions of cycles.
Low moisture absorption and low creep keep critical dimensions accurate in humid or temperature-variable environments.
Ideal for electrical, medical and sensor-adjacent equipment where metal parts would interfere.
Unaffected by common oils, greases and many solvents — suitable for industrial and food-adjacent machinery.
Much lighter than metal equivalents and naturally dampens vibration for quieter, smoother operation.
Beyond POM, we machine a broad range of engineering plastics and metals. Whatever your application needs — higher temperature, stronger chemical resistance, or greater stiffness — we can match the material to the job.
| Category | Material | Typical advantage |
|---|---|---|
| Engineering Plastics | POM / Acetal / Delrin® | Low friction, high stiffness |
| PEEK | High temperature, chemical resistance | |
| PTFE | Lowest friction, non-stick | |
| PA / Nylon (MC, PA6, PA66) | Tough, impact resistant | |
| UHMW-PE | Excellent abrasion resistance | |
| PPS / PSU / PC / ABS / PMMA | Rigidity, transparency, thermal stability | |
| Metals | Aluminium (6061 / 7075) | Light, strong, anodisable |
| Stainless Steel (304 / 316) | Corrosion resistance | |
| Brass / Copper | Conductivity, machinability | |
| Titanium (Grade 5) | High strength-to-weight |
