When the chamfering machine is rotating, no part of the human body should touch the transmission parts. When operating, tie the cuffs, and it is strictly forbidden to work with gloves. The spindle speed change must be carried out after stopping. The gears must be fully meshed when shifting. When the chamfering machine is found to be abnormal, stop and check immediately. When the long material pipe is put into the material rack and the bundled lead wire is loosened, measures should be taken to prevent the pipe from rolling, impacting, and crushing people. It is necessary to check that the dust removal device is in good condition before cutting. When using a grinding wheel chamfering machine, check in advance whether the grinding wheel is damaged, cracked, damp, and the power cord is reliable. The machine must be stopped when changing tools, measuring workpieces, lubricating, and cleaning pipe heads. Before bending the pipe of the chamfering machine, adjust the cutter and clamp the work object. The parking baffle should be fixed, and it can be operated only after the sequence of clamping, unclamping, forward and backward testing.

The safe operation of the chamfering machine also needs to pay attention to the following issues:

The speed change of the main shaft of the chamfering machine must be carried out after parking. The gears must be fully meshed when shifting. When the machine tool is found to be abnormal, stop and check immediately;  

2, adjust the tool and clamp the work object before cutting. The length of the clamping part shall not be less than 50 mm. The parking baffle must be fixed, and it can be operated only after the sequence of clamping, unclamping, forward and backward test runs;

3. When the machine tool is rotating, no part of the human body should touch the transmission parts. When operating, tie the cuffs, and it is strictly forbidden to work with gloves. The head of the human body should deviate from the cutting direction;  

4. When changing tools, measuring workpieces, lubricating, and cleaning the tube head, you must stop;  

5. When cutting the tube head, prevent the tube head from flying out and hurting people;

6. When racking and loosening the bundled lead wire, measures should be taken to prevent the pipe from rolling, impacting, and crushing people;   

7. When using a grinding wheel chamfering machine, check in advance whether the grinding wheel is damaged, cracked, damp, and whether the power cord is reliable;   

8. The dust removal device of the chamfering machine should be intact before cutting;   

9. No one should stand in the direction of the workpiece in and out of the material.
