(1) Matters needing attention
1. Select the appropriate tool and clamp the tool on the tailstock or spindle of the equipment.
2. To ensure machining accuracy, the tool must be aligned with the center of the workpiece axis.
3. When the tool is working, it can be tool rotation or part rotation, and the spindle rotates forward.
4. In order to increase the service life of the tool, please use coolant or cutting oil to cool it when working.
(2) Machining size of hole before punching
1. The hole diameter D is 0.1 mm smaller than the size of the opposite edge of the blade.
2. The hole chamfer is 90 degrees, and the diameter of the chamfer hole is larger than the opposite edge of the knife edge. Play a guiding role.
3. Drilling depth H2≥(1.3-1.5×) effective punching depth (H).
(3) Recommended working parameters
1. Rotation speed: 1300-2000 rpm, the principle of rotating punching tool allows high-speed use, but you should pay attention to high-speed use (such as machining center)
