What is the pressing process of sapphire substrate grinder

Due to the breakage of the connecting bolts of the stretching rod and frequent replacement of the bolts, the flange surface of the stretching rod is uneven, and the surface of the press head of the hydraulic plate of the sapphire substrate grinder is not flat enough. As a result, during the pressing process, the force on the bolts is not uniform, and there is a possibility of the bolts being pulled and bent. The tightened bolts are subjected to uneven force, and the bolts with high force are prone to breakage during operation. So, when the connecting flange is uneven, it should be replaced in a timely manner, and its material hardness and strength are relatively high. The use of hydraulic wrenches when tightening bolts should be correct. The tightening sequence of the tension rod bolts should be carried out in three times. The first time should be pressed to 540bar, the second time to 720bar, and the third time to 960bar. It is not allowed to press it in place at once. The composite function mold polishing machine refers to the combination of ultrasonic polishing with other common mold processing techniques, which is a composite ultrasonic mold polishing machine. It is an essential and convenient tool for mold surface treatment practitioners.
 
The size of the sapphire substrate grinder is also the same as that of the grinding disc. The speed of the grinding disc on the equipment can reach 60RMP, with an inner diameter of 310mm and a thickness of approximately 15mm. The correction wheel has an outer diameter of 410mm and an inner diameter of 360mm, and requires three correction wheels to be equipped simultaneously; The processing size needs to be less than 333mm, and larger models are required if it exceeds this data; Motor power: 7.5KW, 380V, 3-phase; The maximum pressure of the cylinder is 200kg, with 3 cylinders
