There are many functions of CNC lathe. In some cases, the operator will carry out functional experiments on CNC lathe. Generally, the following process will be followed to complete.

1. Functional experiments of machine tools are carried out by keys, switches and manual operation. Flexibility, stability and functional reliability of experimental action.

2. Select a kind of spindle speed of NC lathe as the connecting experiment of spindle start, forward rotation, rotation and suspension. No less than 7 operations.

3. The experiment of high, medium and low rotational speed change of CNC lathe spindle. The allowable difference between the command value and the display value of the rotational speed is (+5%).

4. Choose one kind of feeding quantity, on the whole journey of XZ axis, do the operation feeding and fast feeding experiments successively. Fast travel should be greater than 1/2 of the total travel. Positive and negative side and continuous operation not less than 7 times.

5. On the whole journey of X and Z axes, do low, medium and high feed rate conversion experiments. The turret tool holder is used for various clamping experiments.

6. Hydraulic, smooth, cooling system to do sealing, smooth, cooling experiments, so that no leakage.

7. CNC lathe chuck clamping, loosening, flexibility and reliability experiments.

8. The spindle is rotated, rotated, stopped and changed.

9. Turntable turret tool holder is experimented in both positive and negative directions.

10. The feed organization of NC lathe is experimented with low, medium and high feed rate and fast feed change.

11. Reliability and flexibility of functions such as over-range feed coordinates, manual data input, azimuth display, return to datum point, program serial number indication and retrieval, program pause, program deletion, address line interpolation, linear cutting choke, taper cutting cycle, thread cutting cycle, circular arc cutting cycle, tool azimuth compensation, pitch compensation, gap compensation, etc.
