CNC Knowledge: How to solve the problem of wire cutting and excessive wear and tear

The thread striker accelerates excessive wear or wear

1. Reason: the cutting speed and the quantity of power are not selected correctly.

Solution: Make sure you select the cutting speed and correct power speed in the machining settings table.

2. Reason: the tool is under too much pressure.

Solution: Reduce the flow by tooth; shorten the time change time interval; Check the excessive wear of the tool – the thread at the start carries the fastest.

3. Reason: The selected coating is incorrect, resulting in a dispersed tumor.

Solution: study the applicability of other coatings; Increase the flow rate and flow of the coolant.

4. Reason: The speed of the spindle is too high.

Solution: Reduce the speed of the spindle.

Point

1. Reason: the cutting speed and the quantity of power are not selected correctly.

Solution: Determine the cutting speed and the correct amount of power supply selected in the table of machining parameters.

2. Cause: The thread striker moves or slips on its tightening device.

Solution: Use the hydraulic chuck.

3. Reason: the machining tool is not rigid enough.

Solution: Make sure the part is tight reliably;

4. Reason: Insufficient cooling liquid pressure or flow.

Solution: Increase the flow rate and flow of the coolant.

The steps appear on the threaded tooth

1. Reason: the power rate is too high.

Solution: Reduce food by tooth.

2. Reason: The treatment and programming of the slope grinding adopt the axial movement.

Solution: Make sure that the thread striker is ground for the large diameter of the wire

3. Reason: the milling striker is excessively worn.

Solution: shorten the time change time interval.

4. Reason: the tool processing part and the tightening part are too far away.

Solution: shorten the amount of overhang of the tool on the tightening device as much as possible.

There are differences in the detection results between parts

1. Reason: The tool processing part and the tightening part are too far away.

Solution: shorten the amount of overhang of the tool on the tightening device as much as possible.

2. Reason: The selected coating is incorrect, resulting in a dispersed tumor.

Solution: study the applicability of other coatings; Increase the flow rate and flow of the coolant.

3. Reason: the milling striker is excessively worn.

Solution: shorten the time change time interval.

4. Reason: the room is moved to the luminaire.

Solution: Make sure the part is tight reliably;
