This machine tool is of chuck type common grinding machine which is an applicable for grinding the cylindrical hole and conical hole with cone angle not exceeding 60°. This machine tool is applicable for small batch production.

I. Structural features and performance of the machine tool.

1. The machine tool layout adopts abrasive wheel to perform horizontal feed and work piece to perform vertical reciprocating motion;

2. Feed and dressing compensation of the abrasive wheel is performed by two transmission mechanisms with no mutual interference. There’s no need to adjust the machine tool again after the new abrasive wheel is replaced;

3. Both manual and hydraulic horizontal feed is available of the abrasive wheel. The abrasive wheel will make micro-feed (periodic feed) once after each reciprocating motion of the working table. Stepless regulating of the feed rate is available;

4. The quick jump mechanism of the abrasive wheel is set for the machine tool. Manual tool setting is unnecessary after measuring or dressing upon abrasive wheel retracting;

5. The feed system has fixed-stroke grinding function, which is easy for size control of the work piece during batch production;

6. The motion of the working table is of hydraulic driving. Stepless regulation is available for motion speed. Stop device is set for quick retracting of the working table. The quick retraction stroke can be adjusted based on the practical need to reduce idle stroke time and improve the work efficiency.
