When a problem occurs while grinding, finding the cause is not easy due to the variety of complexly intertwined factors involved. In order to investigate the cause of problems, it’s important to understand what is going on during grinding — things like the condition of the workpiece, the condition of the wheel usage surface, and sound and heat generated by the process — by being ...

But the pressure is not as large as possible. When the limit pressure is exceeded, the pressure will decrease the density of the solid, which is caused by the spallation. The isostatically pressed green body has high strength, high density and uniformity, and can prepare high-performance and high-quality grinding media balls.
