- Soft start and soft stop function
  Chipping of work piece can be prevented with it's smooth motion by applying soft start and soft stop function on the operation of of surface plate
- Variable Velocity on vertical feed of Surface plate
  There can be smooth process with almost no impact based on "sudden drop - slow drop - slow rise - sudden rise" operation  cycle of surface plate
- Pressure variable device on top board
  Optimal condition on work piece because each fine adjustment is possible for each work piece with "initial low pressure - increased low pressure - counter balance pressure" for the pressure applied on the top board work piece
- Stepless variable velocity device
  Lapping velocity control is possible because the rotation velocity and direction is performed as stepless on top board, bottom board and sun gear by individually operating inverter motor
