1. Triangular carbide car blade to do a small cutter
In the narrow and shallow slot, if not suitable cutter, can be found in a triangular carbide car blade into a small cutter.
Find the triangular carbide car blade to measure its thickness, too thick, with a grinder to the size. Press the center hole of the blade size of a milling cutter, the car blade installed on the cutter rod with a small nut after fastening. As the triangular carbide car blade center hole does not have the keyway, can not use the key force, and the small nut tightening force is too small, so should then use the brazing method to weld the blade to the cutter pole. The workpiece is clamped on the fixture and can be milled after a good knife. Because this cutter is negative front angle. Milling depth, feed and milling speed can not be large, and fill the coolant cooling.
2. The end mill can be pressed at the center
The workpiece is a square piece, the middle of a round nest, in the positioning board according to the size of the workpiece processing a square shallow fence, just put the workpiece into the shallow edge or four sides of the milling a small mouth, the tool can be used to milling the workpiece Pull out.
In order to ensure that the workpiece in the milling process will not fly out, specially designed in the center of the end of the workpiece cutter end, the ball pin with a screw cap connected to the end of the end of the cutter body, between the ball pin and the body Compress the spring to the ball pin pressure, so that the ball pin to the appropriate force too on the workpiece.
The milling cutter can also be mounted on a radial drilling machine to use to mill smaller workpieces. The positioning plate can be made of low melting point alloy, and with the pressure plate in the milling machine or radial drilling machine on the table.
