Product Introduction
The purpose and characteristics of the machine tool
This machine tool is a high-precision lead screw grinding machine specially developed for the rolling functional components industry. It is suitable for grinding high-precision arc ball screws, high-precision trapezoidal screws and other threaded tooth profiles.
Transmission and grinding thread length:
CGK-1500 adopts the table moving type, and the grinding thread length is 1500mm.
Adopt SIEMENS828D/840D numerical control system, and equipped with HEIDENHAIN precision grating ruler, Renishaw encoder, to achieve full closed-loop control 9 The operation interface adopts Chinese man-machine dialogue interface, menu input, and easy operation.
The grinding method adopts a single-stroke grinding cycle, which has the functions of automatic cycle grinding, multi-head thread grinding, dynamic tool setting, pitch compensation, mid-diameter taper compensation and automatic compensation of grinding wheel correction.
The main bed and workbench are made of high-strength alloy cast iron, the guide rail surface has been scraped and ground with high precision, and the mother screw and transverse feed screw of the machine tool are imported high-precision grinding ball screws to ensure the accuracy and stability of the movement.
The grinding wheel spindle adopts imported high-precision rolling bearings. It has high rotation accuracy, stiffness, and wear resistance.
