Crystal cutting positioning table

The utility model discloses a crystal cutting positioning table, and particularly relates to the technical field of crystal processing, the crystal cutting positioning table comprises a platform, and a cutting protection mechanism is arranged at the top of the platform; the cutting protection mechanism comprises a fixed base, the bottom of the fixed base is fixedly connected to the top of the platform, two long rods are fixedly arranged on one side of the fixed base, and the outer sides of the long rods are movably sleeved with sliding blocks. By arranging the cutting protection mechanism, compared with the prior art, when the rotating cutting blade makes contact with a crystal, a large number of high-temperature chipping particles are generated, and the annular heat insulation plate on the inner side of the circular baffle on the outer side of the cutting blade intercepts the chipping particles flying out along rotation of the cutting blade; the annular heat insulation plate on the inner layer of the circula
