This centerless grinding machine is applicable for centerless through-feed grinding of cylindrical part, and in-feed grinding of cone and rotary part. It's applicable for mass production. It can also be used for centerless in-feed grinding of cone-shaped parts with conicity no more than 1:20 and the formed rotational parts once the in-feed grinding mechanism is added.

I. Structural Characteristics and Performance of Machine Tools
1. The machine tool is fixed by a grinding wheel frame, and moves through the guide wheel frame;
2. The grinding wheel is of cantilevered structure. The spindle of the grinding wheel adopts multi-piece long bearing bush dynamic-pressure oil film bearing;
3. The front bearing of the guide wheel’s spindle adopts conical-surface sliding radial bearing, and the rear bearing is radial thrust combined ball bearing;
4. The transverse feeding mechanism adopts fluorine-containing plastic-coated guide rails and feeding-purpose differential screw rods;
5. Trimming machines for both grinding wheel and guide wheel are hydraulically driven, and equipped with profiling devices, which are suitable for cutting and grinding multi-step workpieces;
6. The speed change of guide wheel’s spindle adopts the change gear (variable frequency speed adjustment can be designed according to the user's needs).
