The following points need to be paid attention to when using extrusion taps:
Choose the right tap: Choose the right type of tap according to the processing needs. For example, screw-tip taps are used for through-hole machining and extrusion taps are used for blind hole machining
Ensure the integrity of the surface of the workpiece: there shall be no chips, cracks and other defects on the surface of the workpiece, otherwise the tapping effect will be affected
Use the right lubricant: Choose the right lubricant, such as engine oil, vegetable oil or molybdenum disulfide, and change the lubricant regularly to keep the tapping smooth
Control the speed and strength of tapping: master the speed and strength of tapping, and avoid excessive friction heat, so as not to shorten the life of the tap
Keep the tool stable: When tapping the iron, keep the tool stable to avoid offset, otherwise the thread will not be able to bite in the metal
Control aperture error: Extrusion tapping has high requirements for aperture error, and the error range needs to be controlled within 5% of the tooth distance
Dealing with burrs and tooth mouths: the hole surface of the internal thread is easy to produce burrs, and chamfering processing needs to be carried out according to the situation; A U-shaped notch will occur on the top of the thread, and the opening within the appropriate range will not affect the function of the thread
Applicable material range: Extrusion tapping is suitable for materials with ductility, such as aluminum alloy and steel, but not for quenched and tempered steel and high hardness steel with hardness exceeding HRC35
