Machine tool main drive:

Machine tool main drive by mechanical variable speed motor and speed regulating electrical appliances can obtain 2-560 - r/min1000 r (optional) the infinite speed range to meet the needs of various machining.

The transmission structure:

X axis traverse by eliminating gaps for the double pinion and rack structure of the whole feed structure in a slide in the body and therefore good rigidity and transmission can be eliminate the clearance adjusting
Spindle box vertical feed (Y) with ball screw pair drive screw fixation in the first column on the feed motor through slow down gear drives the rotating spindle box to get the vertical feed
Z axis W axis driving principle of the ball screw vice same as Y-axis.

Precision compensation system:

TK69 CNC floor-type boring and milling machine series adopts automatic gravity compensation system to ensure the balance of spindle box body and prevent slippery pillow moved forward when the main spindle box focus changes and make the spindle head.

Guide:

Former pillar traverse spindle box for vertical feed and ram the axial feed adopts the static pressure guide rail machine precision has good damping shock absorption effect to keep good long life high reliability.
