                           0.02mm

          This is usable for boaring sleeve (screw clamp) and colletchuck, please                                  max.
          be sure to set deviation amount under 0.02mm between workpiece and                                       0.02mm

            Flat Surface                    1. Due to good chip control, step machining is not necessary for soft steel like SS400.
                                            2. When machining SUS304, for hole depths of more than 2.5D, utilize the step machining

           Stacked Plates                   3. In order to have smooth chip removal, we recommend internal coolant.

                                            1. Fix stacked plates securely to ensure they do not slip while machining.

          Pipe Material                     1. Hole machining above the centerline of the pipe is possible.
                                            2. Do not machine on curved surface areas.
