Everyone should be familiar with thread turning inserts. Let me share with you the rational use and replacement of thread turning inserts.
Everyone should be familiar with thread turning inserts. Let me share with you the rational use and replacement of thread turning inserts.
According to the three failure factors of thread turning inserts, the rational use measures of thread turning inserts are put forward:
How to save inserts in thread turning, internal thread turning inserts
1. The greater the cutting depth, the longer the contact time between the tool and the material, and the more friction and heat generation. In order to avoid thermal erosion of the carbide tip of the tool, it is necessary to increase the amount of water sprayed to cool the tool tip. In order to throw out the material, reduce the contact probability between the tool and the material under the car, and reduce the wear of the thread turning blade.
2. Select the tool according to the cutting power
3. Check the rotation and wear of the thread turning insert every 6 to 8 hours to ensure that the installed tool can rotate freely in the tool seat hole. If the tool is severely worn, it should be replaced in time. The protruding length of the tool has a great influence on the construction quality. When replacing the tool, try to ensure that the protruding length of the tool is the same.
There are two reasons for thread turning insert replacement.
1. With the wear of the tool tip, the diameter of the tool tip becomes larger, resulting in a reduction in cutting capacity and a reduction in the operating efficiency of the machine. Second, the worn thread turning inserts result in different diameters of the cutting circle at the tip, uneven surface of the workpiece being turned, and reduced work quality of the machine.
2. Although delaying the replacement of thread turning inserts so that they can continue to work in a worn state can save the cost of the cutter head, the dulled cutter head will reduce the working speed and cutting output. Therefore, timely replacement of worn thread turning inserts is conducive to improving economic efficiency.
