1) Adopt AC slip motor drive, soft start, soft stop, smooth operation.
2) The lower grinding disc can be raised and lowered, it is convenient to place and remove the workpiece.
3) The upper plate is set to slow down, which not only effectively prevents the crushing of the brittle workpiece, but also independently controls the pressure.
4) The pressure preset counting method is used to control the grinding pressure, and the number of grinding cycles and requirements can be accurately controlled.
5) The grinding disc can be trimmed by the trimming method.
6) According to user requirements, connection with ALC (frequency monitor) can be set.
