Micron-Grade Grinding & Assembly

All linear rails undergo surface grinding on high-precision CNC machines to ensure rail edge flatness and rail-body parallelism below 5 microns. This enables stable sliding motion and accurate positional control.

Blocks are assembled using torque-controlled fixtures that guarantee even internal pressure distribution. This prevents over-tightening or asymmetrical assembly that could cause deflection or drag.

Each block is matched to its rail with strict preload control. Options include ZF (zero preload), Z1 (light preload), and Z2 (medium preload), allowing designers to choose the right balance of rigidity and smoothness for their system.

Rail ends are precision chamfered and deburred to prevent ball jamming and ensure seamless block entry, especially critical for applications with frequent movement or block exchange.

Both the rail and the block are finished with micro-honed ball grooves to reduce vibration and maintain consistent ball circulation under dynamic conditions — ensuring long-term wear resistance.

Each guide pair is visually inspected and randomly selected for dimensional checks before packing. This ensures every unit shipped meets the tolerance criteria expected for precision automation systems.
