CNC Floor type Boring Mills

with movable column

Horizontal drilling and boring machines of TK69 series are the heaviest and with the greatest technological possibilities for processing large-sized and heavy prismatic and body parts. This is supported by the concept of a movable column providing a very large machining length combined with a vertical crown spindle box, with a rotating spindle for drilling and boring operations housed in a milling spindle. The additional rectangular milling spindle is used to fasten milling heads or a face plate. The CNC rotary table also has a transverse movement and larger and heavier parts can be tightened on the floorboards that are capable of precise leveling.
