In the working process of double face grinder, due to the reasons of tool wear and workpiece clamping, it is necessary to adjust the position of each axis of the machine tool, so that the debugging time of the machine tool occupies a considerable proportion. In order to shorten the debugging time of machine tools and improve the effective processing time, it is of great significance to provide a set of good debugging means of machine tools. At present, the commonly used debugging functions of double face grinder are as follows:

1. The manual function is jogging, fixed length and manual pulse generator feeding function;

2. Return to zero, return to mechanical origin function;

3. Real time speed multiplier adjustment function;

4. Tool radius wear and tool length wear compensation function;

5. Functions of parallelism, finding rectangular center line and center point;

6. Center finding function;

7. Automatic tool setting, tool changing and tool compensation functions.
