Axis travel, table size and positioning accuracy determine which jobs a machine can handle. A machine rated for 500 mm × 400 mm × 300 mm travel won’t accommodate larger components without fixture modifications or multiple setups. Repeatability specifications, measured in microns, tell you whether the machine can hold tight tolerances across production runs.

Insufficient rigidity creates chatter, poor surface finish and rapid tool wear. Guideways and ball screws control how the axes move and position. Their condition affects repeatability, surface finish and rapid movement performance. Correct lubrication and periodic inspection maintain accuracy over time — particularly important in Indian shop floors where ambient temperatures swing widely between seasons and humidity during the monsoon accelerates corrosion on unprotected ways.
