Introduction

TK6920 TH6920 type CNC floor-type milling/boring machining center, for the square ram mobile spindle box structure, the structure adopts the advanced ram deformation compensation technology; X, Y, Z, W axis adopt preloading no clearance and high precision ball screw drive structure; Guide rail USES the hydrostatic guideway structure; X, Y and W axes adopt HAIDENHAIN grating ruler to realize closed loop control; Machine tool control adopted the German Siemens 840 d system, can realize arbitrary 4-axis linkage function, can be equipped with two degrees of freedom of the high precision angular milling head, can realize five coordinate linkage space; The machine performance is stable and reliable.

Clamped on the machine can process artifacts, complete a wide range of processing, milling, boring, tapping processing and five coordinate space curved surface and curve processing (such as propeller blades, etc.), high precision, good rigidity. The machine tools such as equipped with vertical milling head, universal milling head, elongation milling head and nc rotary table, applications will be more widely, especially suitable for large, heavy and super-heavy complex shaped workpiece machining. Besides the machine with automatic changing accessories, automatic replacement tool (with up to 60 of the cutting tool knife library, which can realize vertical tool change).
