CNC lathe tool testing is an important and delicate process that requires following a series of precautions to ensure safety and processing accuracy. Here are some key considerations:

1. Preparation before setting the knife:

Check the model, mechanical structure and operation mode of the CNC machine tool to ensure a full understanding of the machine tool.

Check the operating status of the CNC machine tool and observe whether the operation process is normal to avoid accidents during the tool setting process.

Check whether the workpiece and tool clamping of the CNC lathe are secure to ensure safe operation.

2. Trial cutting process:

When the CNC lathe runs the tool to 30~50mm of the workpiece surface, it must verify whether the remaining coordinate values of the coordinate axes, the X-axis and Z-axis coordinate values are consistent with the drawing while maintaining feed.

CNC lathes can use a "progressive" method for some tools that require tool testing. For example, first try boring a small length, and then boring to the entire length after passing the test.

During the trial cutting and processing of CNC lathes, after replacing tools and auxiliary tools, the tool length must be re-measured and the tool compensation value and tool compensation number must be modified.

When retrieving CNC lathe programs, you should pay attention to whether the position pointed by the cursor is reasonable and accurate, and observe whether the coordinates of the tool and machine tool movement directions are correct.

After the CNC lathe program is modified, the modified parts must be carefully calculated and checked.

3.Safe operation:

After the CNC lathe is powered on, check whether the switches, buttons and keys are normal and flexible, and whether there are any abnormalities in the CNC lathe.

When inputting the workpiece coordinate system, the coordinates, coordinate values, positive and negative signs, and decimal points should be carefully checked.

Before loading the workpiece on the CNC lathe, run the program once to see if the program can run smoothly, whether the tools and fixtures are installed properly, and whether there is any overtravel.

The CNC lathe must be started only after confirming that the workpiece is clamped. It is strictly prohibited to measure or touch the workpiece while the workpiece is rotating.

When the workpiece jumps, shakes, abnormal sounds, loose fixtures and other abnormal situations occur during the operation of the CNC lathe, it must be stopped and dealt with.

CNC lathes that follow these precautions can ensure the safety and processing accuracy of the CNC lathe tool test process, thereby improving production efficiency and reducing potential risks.
