Existingmanufacturingfor carbide cutter, generally comprises a cutter rod and a cutter head, the cutter bar and the tool head is two parts separately machining, tool head is made of cemented carbideprocessing, turning head mounted to the knife rod, the blade part turning head are generally wider than the width of the knife rod part of the car or on the coarse fine car to facilitate. However, the tool head and the cutter rod installation will always produce precision finishing installation error, and blade turning head due to the difficulty of processing and single shape, it is difficult to achieve the processing of complex shape parts.

How to solve the problem that the precision of carbide turning tools is not high enough

Carbide cutting tool comprises a cutter rod and connected with the cutter head and the cutter rod end, wherein the knife rod and the cutter head are integrally formed,the cross section of the cutter rod part is square, an angle of the cutter head to the cutter bar section tilt, tilt to the the tip is formed at the edge of the knife head,the side of the blade tip protrusion section for the knife rod, wherein the blade section is inclined to the point between the concave circular arc.

Triangular cemented carbideblade changed to small milling cutter

In the milling of narrow and shallow groove, if there is no suitable milling cutter,which can find a triangularcemented carbideblade, this made into small carbidecutter.

After finding the triangular cemented carbide blade, measure the thickness of it and use it as thin as possible when it is too thick. According to the center hole size of the blade,a milling cutter rod is made. The blade is mounted on the milling bar and then fastened with a small nut. Because of the hard alloy blade triangular car center hole without keyway,not with the key force, while the small nut fastening force is too small, so we should use the car blade welding brazing method to cutter rod. The workpiece is clamped on the fixture and can be milled after a good knife. Because this kind of milling cutter is negative front angle.Milling depth,feed rate and milling speed can not be large, and add coolant cooling.

End milling cutter capable of compressing workpiece in center

The workpiece is a square, with a round hole in the middle, the positioning plate according to the size of the workpiece processed with square shallow nest, just put into the workpiece, in the shallow pit or four edges milling out a small mouth, available tools to pull the milling workpiece.

In order to ensure the workpiece in the milling process can not fly out,especially the design of the end milling cutter in the center of the workpiece, the lower end is connected to end mill body screw sleeve ball head pin between the ball head pin and the knife body and a compression spring to put pressure on the ball head pin, so that the ball head pin to fit in too the workpiece.

The carbidecutter can also be mounted on a radial drilling machine for use in milling smaller workpieces. The locating plate can be made of low melting point alloy and tightly pressed on the table of the milling machine or the radial drilling machine.
