Custom CNC Machined POM Precision Slider Block For Automation Equipment

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:

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.

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.

Key machining highlights that give the block its precision feel:

• Stress-relieved, distortion-free cutting — POM is machined with controlled temperatures so the finished block stays flat and true.
• Tight tolerance on fit faces — the sliding slot and mounting faces are held to ±0.02 mm for no-play, no-bind movement.
• Sharp, clean edges — every edge is deburred and chamfered, protecting operators and mating parts.
• Consistent surface finish — polished sliding surfaces keep friction low and extend wear life.

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.
