How a single-sided grinder works:
The grinding and throwing materials are placed on the grinding disc, the grinding disc rotates counterclockwise, the correction wheel drives the workpiece to rotate, and the workpiece is pressurized by gravity, and the workpiece and the grinding disc are relatively operated and rubbed to achieve the purpose of grinding and polishing. The grinding disc dressing mechanism adopts the hydraulic suspension guide rail to reciprocate back and forth, and the diamond dressing knife precisely dresses the grinding surface of the grinding disc to obtain the ideal plane effect.
How the double-sided grinder works:
The upper and lower grinding discs rotate in opposite directions, and the workpiece moves in the carrier in a traveling motion that rotates and rotates. The grinding resistance is small, the workpiece is not damaged, and the grinding efficiency is high on both sides. There is a grating thickness control system, and the thickness tolerance of the processed product can be controlled. The device of the double-sided grinder includes two grinding discs, a cruise ship, four motors, a sun gear, a trimming machine, etc. Compared with the two, the structure of the double-sided grinding machine is relatively more complicated, but if the workpiece that needs to be double-sided grinding is grinded with a double-sided machine, the efficiency of the single-sided machine is virtually twice as fast. The birth and development of this double-sided grinding machine has brought improvements to the production efficiency of many industries. There are more silicon wafers, sapphire substrates, epitaxial wafers and so on in the optical glass industry.
