TH (TK) 69 series CNC floor boring and milling machining center
Product details
Machine tool features:
Adopting a floor standing layout with column movement and spindle box hanging on the side. The main motion of the machine tool is the rotational motion of the spindle. The five linear motion coordinate axes are: horizontal movement of the column (X-axis); The spindle box moves vertically up and down (Y-axis); Axial movement of the slider (Z-axis); Axial expansion and contraction movement of boring shaft (W-axis); Vertical movement of the rotary worktable (V-axis). A rotational motion coordinate axis is the rotational motion of the turntable (B-axis). It can be positioned with arbitrary 360 ° indexing and comes with hydraulic clamping.
Adopting high-performance CNC system control, AC spindle motor, all axes are driven by AC servo motor. X. The Y, Z (W, V), and B axes can be linked together, and the spindle has accurate positioning function. The machine tool can perform rigid tapping.
The main drive is transmitted from the spindle motor to the spindle through a two-stage gearbox and gear reduction, meeting the requirements of strong cutting.
● Feed drive shaft: The X-axis adopts a dual gearbox to drive the rack transmission; Y. The V-axis drives the ball screw transmission through the gearbox; Z. The W-axis is directly driven by a servo motor through an elastic coupling to feed the ball screw; X. The Y, Z, V, and B axes are closed-loop controlled.
The X, V, and Z axes are composite guide rails that combine plastic sliding and rolling blocks; Y. The W-axis adopts wear-resistant sliding guide rails. The X axis of TH (TK) 6916/6920 adopts static pressure guide rail, which has strong heavy load capacity, high motion stiffness, and smooth low-speed motion without crawling.
