Tapping machine is a machine shell, device face, nut, flange, etc with different specifications of the hole or blind hole of the medial aspect of the component hole machining internal thread, screw or buckles mechanical processing equipment.
Tapping machine is in use process will often encounter all sorts of problems, the following are tapping machine using process common several problems and solutions and prevention measures.
1, the broken tap: the reason may be the diameter of the thread bottom hole is not accurate.
If you want to avoid this situation happen, should be correctly select the thread bottom hole diameter; When drill a bottom hole, depth should meet the standard; Increase the tap of anterior horn, shorten cutting cone length; Can also be appropriate to reduce the cutting speed.
2, screw tap wear too fast: the reason may be the pitch diameter of thread is not accurate.
Should choose reasonable precision grade screw tap pitch diameter; Choose the suitable cutting fluid and decrease the cutting speed; Timely removal grinding taps produce burrs, and appropriately increase cutting cone length.
3, slide tooth: the reason may be encountered the larger sand holes when tapping, screw tap skid.
Should pay attention to check the bottom hole before tapping; Thought to concentrate when tapping, measured hole deep beforehand, and make a deep mark on the screw tap.
4, tapping screw hole slanting: the reason may when hand tap and work piece end face is not vertical; Machine tapping don’t aim at work piece hole center.
When tapping should hold the screw steady, guarantee the tap and hole end face verticality, such as is not vertical, slightly pressure tap hinge hand shank, and makes positive and reverse the tap continuously, slowly correction; The machine tapping screw tap should aim at the work piece hole center.
Whether machine tapping or hand tapping, should be careful, lest appear problem, increase the burden of human resources. Every factory wants to use the lowest cost to gain more interests.
