High precision cartridge type spindle is equipped with four pieces of Class 7 (P4) angular contact ball bearings plus a set of N-N needle roller bearings in front of spindle.
Precision ball screws (C3 grade) on cross-feed and down-feed axes are directly coupled to Delta AC servo motors.
Roller type linear guideway design for longitudinal movement of spindle head
Automatic cycle + continuous flow lubrication system for guideways, ball screw and table.
The column is anchored to a solid steel ground beam to ensure table load not to affect column alignment.
Linear roller bearings sliding on steel guideways to ensure smooth and stick-slip free movement while the robust lower box way guides coated with anti-friction material in order to provide maximum rigidity.
Both horizontal and vertical wheel head is positioned with a Class C2 ball screw to counterbalance with a pneumatic cylinder to ensure precise movement.
