Magno qualitas M35 Machina spiralis taps Laudate CCCLXXVI spiralis filum taps

Analysis in quaestionem de immatura fractionis taps, rationabile lectio taps: et ICTUS genus est rationabiliter determinari secundum workpiece materia et profundum foraminis, m5 * 0.8 eligere 4.2mm deorsum foramen. Misuse of 4.0mm will cause breakage.；Workpiece material problem: the material is impure, there are excessive hard points or pores in the part, and the tap instantly loses balance and breaks；Choose flexible chuck: set a reasonable torque value with a chuck with torque protection, which can prevent breaking when stuck；Synchronous compensation tool holder: it can provide axial micro-compensation for the non-synchronization of speed and feed while rigid tapping；Poor quality of cutting fluid: Problems with the quality of cutting fluid and lubricating oil will affect the accuracy of the thread and the life of the tap；Cutting speed feed: too small thread accuracy is poor, too high will break the tap directly, depending on the master's experience；Blind hole hits the bottom hole: When machining the blind hole thread, the tap is about to touch the bottom of the hole, and the operator does not realize it
