2024-06-26

1. Line dividing method and correct line dividing. If the line splitting method is not properly selected, the line splitting operation is not correct, and the line splitting error occurs, the pitch of the multi-line thread being turned will be unequal, which will seriously affect the screwing accuracy of the internal and external threads and reduce the service life.

2. Taiwei machine tool reminds that the adjustment of lathe exchange gear should be determined according to the lead, and the position of lathe handle should be adjusted correctly.

3. The lead of the multi-thread is large, and special attention should be paid to the influence of the lead on the rear angle of the two cutting edges of the tool. Qingdao Taiwei machine tool suggests that its spiral lift angle should be calculated according to the lead, and attention should be paid to it in the sharpening market.

4. When finishing turning multi-thread threads, finishing turning should be done together after all spiral grooves are roughly turned, otherwise it is difficult to ensure the consistency of thread profile.
