Difference Between Double And Single-sided Grinder

The devices of the two devices are basically the same, and the consumables and configurations used for the same type of workpiece are the same. The grinding principle and scope of application of the machine are the same. The difference is that there are two grinding discs on the double-sided grinding machine, the upper grinding disc and the lower grinding disc, both of which are parallel. On a single-sided grinder, there is only one grinding disc.

The main difference between a double-sided grinder and a single-sided grinder is that the double-sided grinder grinds both surfaces at the same time, while the single-sided grinder only grinds one side of the workpiece, and the overall efficiency of the double-sided grinder is higher. Some, but some workpieces cannot be ground by a double-sided grinder, and some workpieces only need to be ground on one side, so only a single-sided grinder is needed.

The working principle of double-sided grinder:

The upper and lower grinding discs rotate in opposite directions, and the workpiece performs a planetary motion of both revolution and rotation in the carrier.

The grinding resistance is small and does not damage the workpiece, and the two sides are evenly ground and the production efficiency is high. With grating thickness control system, the thickness tolerance of processed products can be controlled. The device of the double-sided grinder includes two grinding discs, a cruise wheel, four motors, a sun gear, a shaving machine, etc. Compared with the two, the structure of the double-sided grinding machine is relatively complicated, but if the workpiece that needs to be ground on both sides is ground with a double-sided machine, the efficiency of the double-sided machine is virtually twice as fast as that of the single-sided machine.

The birth and development of this double-sided grinder has brought improvements to the production efficiency of many industries. Silicon wafers, sapphire substrates, epitaxial wafers, etc. in the optical glass industry are mostly used.
