After Tapping tap experience wear and tear and blade breakage, their sharpness can be restored through grinding, usually by grinding the front and rear angles of the grinding teeth.

1) Grinding in front of the cutting edge. When the cutting edge of an Squeezing tap is passivated or stuck with chips, thereby reducing its sharpness, a cylindrical oilstone can be used to grind the front of the cutting force. When grinding, apply some engine oil on the oilstone, keep the oilstone stable, and be careful not to cut the small corners of the cutting teeth.

Clean the Tapping tap thoroughly after grinding. When the cutting teeth of an Tapping tap wear to the limit and become broken, a sheet-like grinding wheel can be used to polish the front of the grinding teeth on the grinder. After grinding, use a cylindrical oilstone to grind and improve the roughness of the front teeth and chip groove.

2) Grinding of the back corner of the cutting edge. When the cutting edge of an machine tap is damaged, the back corner of the cutting edge can be repaired on a regular grinding wheel. When grinding, pay attention to the consistency of the cutting cone. When turning an Tapping tap, do not let the tip of the next blade touch the grinding wheel To avoid grinding off the sharp edges of the blade teeth.
