Scope of use of 9B double-sided grinder:

This machine is mainly suitable for grinding or polishing thin and brittle metals or non metals such as silicon wafers, quartz wafers, optical crystals, glass, gemstones, lithium niobate, gallium arsenide, ceramic wafers, etc.

Principle of 9B double-sided grinder:

This series of grinding machines are precision grinding equipment, with the upper and lower grinding discs rotating in opposite directions, and the workpiece moving in a planetary motion with both revolution and rotation inside the carrier The grinding resistance is small and does not damage the workpiece, and both sides are ground evenly, resulting in high production efficiency

Characteristics of 9B double-sided grinder:(The product pictures and parameters are for reference only. For details, please call:)

1. Adopting AC variable frequency motor drive, soft start and soft stop, stable and reliable.

2. The oil pressure lifting gear ring is very stable, and there are shims under the sun gear to adjust the position, effectively utilizing the gear ring and sun gear.

3. The upper plate is equipped with a separate slow descent cylinder, which not only effectively prevents the breakage of thin and brittle workpieces, but also allows for independent pressure control.

4. By using an electronic preset counter, the number of grinding cycles and requirements can be accurately controlled.

5. The grinding disc can be repaired using a disc repair method.
