The accuracy of the drilling of the coupling hole is standard. Entity coupling manufacturer technically explains the key points of drilling

 CouplingThe accuracy standard of the connecting hole drilling is the main point of qualified products!Mechanical asCoupling manufacturerJust briefly talk about my own experience: inCouplingWhen drilling, the standard speed of the drilling machine should be selected according to the material of the coupling. The second is the reasonable speed of the drilling machine. The feed rate of the three drilling machine is the key to the smoothness of the coupling hole. For example: H350 The cast steel coupling drills a hole with a diameter of 20mm, and the speed is generally 400 rpm. The feed rate is 0.22, which is reasonable. You can make a high-quality coupling product hole!Today, I won’t give a brief description one by one.
