Machine Introduction

 

 

This machine is a high-precision screw grinding machine specially developed for the rolling functional parts industry. It is suitable for grinding high-precision arc ball screws, high-precision trapezoidal screws and other threaded tooth shapes.

Transmission mode and grinding thread length:

CGK-2000/3000 adopts table moving type, grinding thread length 2000, 3000mm.

It adopts SIEMENS 828D/840D CNC system and is equipped with HEIDENHAIN precision scale and Renishaw encoder to realise full closed-loop control.9 The operation interface adopts Chinese human-machine dialogue interface with menu-type input, which is easy to operate.

The grinding mode adopts single-stroke grinding cycle, with the functions of full automatic cycle grinding, multi-head thread grinding, dynamic tool setting, pitch compensation, centre diameter taper compensation and automatic compensation of grinding wheel correction amount.

The main bed and table are made of high-strength alloy cast iron, and the guideway surface is scraped and ground with high precision. The machine's female screw and transverse feed screw are made of imported high-precision ground ball screws to ensure the precision and stability of movement.

The grinding wheel spindle adopts imported high-precision rolling bearings. It has high rotary precision, rigidity and wear resistance.



 

Machine Features

 

 

It is mainly used for the grinding of the external threads of ball screws. It can machine threads that meet high - precision requirements, ensure the accuracy of parameters such as pitch and thread profile, and improve the transmission accuracy of ball screws.

It can reduce the surface roughness, avoid surface defects, and enhance wear resistance and service life.
