Tap is a commonly used tool for processing internal threads. There are different types of taps according to different classification methods:

Sharpening process: The cutting part of the tap is sharpened through a sharpening machine to ensure the cutting performance and thread quality of the tap.

It may be caused by the selection of a small bottom hole for the thread, poor chip removal, insufficient drilling depth when the thread cannot be tapped, high cutting speed during tapping, different axes between the tapping tap and the bottom hole, inappropriate selection of tap grinding parameters, unstable workpiece hardness, and excessive wear of the tap. The solutions include: selecting the appropriate diameter of the threaded bottom hole, improving chip removal, increasing drilling depth, reducing cutting speed appropriately, correcting the fixture, increasing the lead angle of the tap, shortening the length of the cutting cone, controlling the hardness of the workpiece, selecting safety card heads, and replacing the tap in a timely manner.

It may be caused by incorrect tap selection, high cutting speed, insufficient cutting cone length, poor chip removal, small bottom hole diameter, cold and harsh conditions, etc. The solutions include: selecting the correct tap according to the processing conditions, reducing cutting speed, increasing the length of the cutting cone, improving chip removal, controlling the hardness of the workpiece, and selecting safety clamps.

In addition, the production process of taps includes about 20 processes, mainly including three parts: rough machining of materials, heat treatment and finishing. The tap production equipment used for finishing is mainly a grinder, not only because of the high processing accuracy of grinding, but also because the hardness of the heat-treated tool steel is very high and can only be processed with a grinder. These tap production equipment mainly include tap square tail grinding, tap cylindrical grinding, tap groove grinding and tap thread grinding, etc.

It may be caused by incorrect tap selection, poor spindle rigidity of the machine tool, and incorrect tap tolerance selection. The solutions include: selecting the correct tap according to the processing conditions, using floating tapping threads, selecting the correct tap tolerance, etc.

It should be noted that the specific solution needs to be analyzed and determined based on the specific problem. When performing tap machining, operators should have a high level of skill and experience in order to better deal with various problems and improve machining quality.

A tap is a tool used for cutting threads, commonly used for machining various sizes of internal threads. When using a tap, it is important to choose the appropriate type, material, and size of the tap, as well as the correct usage method, to ensure machining efficiency and thread quality.

Turning process: The shape of the tap is processed into a cylinder through a lathe, and the accuracy of its diameter and length is ensured.

It may be caused by excessive selection of the lead angle of the tap, excessive cutting thickness of each tooth of the tap, high tap hardness, tap wear, and other reasons. The solutions include: reducing the front angle appropriately, increasing the length of the cutting cone appropriately, reducing the hardness appropriately, and replacing the tap in a timely manner.

Reduce the number of chip slots in the tap and expand the chip space in the chip slots; Increase and deepen the bottom hole.
