19/5000 Understand the common problem analysis and solution of thread milling cutter.

Date of release:2016-07-27 Author: Click:

(1) thread milling cutter accelerates wear or excessive wear.

The reason: the cutting speed and the quantity of feed are not correct. Solution: ensure that the correct cutting speed and feed amount are selected from the machining parameter list.

Reason: the tool is under too much pressure. Solution: reduce the supply of each tooth; Shorten the time interval for changing knives; Check the excessive wear of the tool - the thread at the beginning will wear out the fastest.

The reason: the selected coating is not correct, and it produces the debris tumor. Solution: to study the applicability of other coatings; Increase coolant flow rate and flow rate.

Reason: the spindle speed is too high. Solution: reduce spindle speed.

(2) the cutting edge is broken.

The reason: the cutting speed and the quantity of feed are not correct. Solution: determine the correct cutting speed and feed rate from the machining parameter table.

Reason: thread milling cutter can move or slip on the clamping device. Solution: hydraulic clamp is used.

The reason: the machine tool is not rigid. Solution: determine the workpiece clamp is reliable; If necessary, reclamp the workpiece or improve the clamping stability.

Reason: the coolant pressure or insufficient flow. Solution: increase coolant flow rate and flow rate.

(3) there are steps on the shape of the thread.

Reason: the rate of admission is too high. Solution: reduce the supply of each tooth.

Reason: the machining programming of slope milling adopts axial movement. Solution: make sure that the thread milling cutter is milling out of the tooth profile at the large diameter of the thread instead of radial movement.

Reason: excessive wear of thread milling cutter. Solution: shorten the time interval.

Reasons: the cutting tool parts are too far away from the holding parts. Solution: shorten the overhang of the cutter in the clamping device as much as possible.

(4) there are differences between the workpiece and the workpiece.

Reason: the cutting parts of the tool are too far away from the holding parts. Solution: shorten the overhang of the cutter in the clamping device as much as possible.

Reason: the selection of the coating is incorrect, resulting in the debris tumor. Solution: to study the applicability of other coatings; Increase coolant flow rate and flow rate.

Reason: excessive wear of thread milling cutter. Solution: shorten the time interval.

Reason: the workpiece is shifted on the fixture. Solution: determine the workpiece clamp is reliable; If necessary, reclamp the workpiece or improve the clamping stability.
