1. The machine layout adopts a single-sided movement mode of the guide wheel frame, and the feed guide rail adopts a double V-shaped rolling rigid guide rail (GCR15). The feed mechanism is driven by servo electric drive, achieving sensitive displacement, feed and compensation movements of the guide wheel frame, accurate positioning, long service life, and good system rigidity;
2. The linear speed of the grinding wheel is 45m/s, which has strong cutting ability, low grinding wheel wear rate, and good grinding surface quality. Compared with the linear speed of the 35m/s grinding wheel, the cutting surface ability and the service life of the grinding wheel can be improved by 20% to 30%;
3. The grinding wheel and guide wheel shaft both adopt a suspended structure, making it convenient to replace the grinding wheel and guide wheel;
4. The adjustment of the guide wheel adopts AC variable frequency infinite adjustment;
5. The operation adopts a display screen human-machine dialogue, with an automatic cutting in grinding program, and the feed rate, speed, and time can be adjusted;
6. Yonghua can enhance performance by selecting cutting mechanisms, long workpiece grinding brackets, magnetic separators for cooling systems, and other components through special ordering methods.

This machine tool can be used for central grinding of various cylindrical and annular parts, suitable for mass production. After adding a cutting mechanism, it can be used for central cutting grinding of conical and formed rotary parts with a taper not greater than 1:20. Compared with similar machine tools, it has the characteristics of good rigidity, strong grinding ability, and high durability of grinding wheels.
