There are mainly 4 types of problems commonly encountered in tap tapping. For different types of problems, swintool sorts out the causes of these problems and the corresponding solutions Tractor top link, as follows:

1. The internal thread is too large

Reasons and corresponding solutions:

(1) The tap type is incorrectly selected. Choose the correct tap according to the processing conditions.

(2) The bottom hole is eccentric, use floating tapping/improve bottom hole instead.

(3) The axial feed is not uniform, so use floating tapping/improving machine tools instead.

(4) If the tap tolerance is wrong, choose the correct tap tolerance.

(5) Chip jam, reduce the number of tap chip flutes, expand the chip flutes and chip space; enlarge and deepen the bottom hole.

(6) The cutting speed is too high, reduce the cutting speed.

2. The internal thread is too small

(1) The tap type is incorrectly selected. Choose the correct tap according to the processing conditions.

(2) The rigidity of the machine tool spindle is not good, so use floating tapping instead.

(3) If the tap tolerance is wrong, choose the correct tap tolerance.

3. The surface roughness of the internal thread is too high

(1) The tap type is incorrectly selected. Choose the correct tap according to the processing conditions.

(2) The cutting speed is too high, reduce the cutting speed.

(3) The cutting cone length is not enough, increase the cutting cone length.

(4) Chip removal is not smooth, choose the correct tap according to the processing conditions.

(5) The bottom hole diameter is too small, choose the bottom hole diameter according to the corresponding standard.

(6) Cool, improve cooling and lubrication conditions.

4. The tap is broken during processing or retraction

(1) When tapping the thread, the tap touches the bottom of the hole, check the depth of the hole bottom.

(2) If the cutting torque is too large, shorten the tapping length and use thread groove taps.

(3) The bottom hole is too small, choose the bottom hole diameter according to the corresponding standard.
