In the process of cnc shaft, we often encounter some products which need to be tapped. For example, the production technology for the cnc shaft is to lathe outer circle and end face then tap secondly. In the process of tap, tap breakage is often encountered. Then the following need to be considered during the cnc shaft production

The tap is not properly selected

High quality taps should be used for tapping with too much hardness, such as cobalt high speed steel taps, cemented carbide taps, coating taps, etc. For difficult-to-machine materials such as stainless steel and high-temperature alloys with high hardness and good toughness, the tap may break due to its insufficient strength and cannot resist the cutting resistance of tapping. So we should choose high-strength material taps (such as powder high temperature steel, etc.) to increase the strength of the tap itself; at the same time, improve the surface coating of the tap to increase the surface hardness of the wire.
