This machine can auto aiming the tool, actually test the grinding torque,automatic adjust the grinding speed, so to avoid broking the wafer.

1,Can grind the wafer to 80um, and the planeness and parallelism can be +-0.002mm.
2,High speed, LED sapphire substrate can be 48um/minute, silicon wafer can be 250um/minute.
Application
suitable for high hardness,thin,and high precision product. like LED sapphire substrate,quartz crystal,silicon wafer,ceramic,wolfram plate, germanium plate thinning(grinding)
