Description

Special-shaped groove milling cutter

Technical Field

The utility model relates to the field of cutters, in particular to a special-shaped groove milling cutter.

Background

The shapes of the metal parts are quite different, and different cutters are also used in the process of preparing the parts. Milling tools are rotary tools for milling machining having one or more cutter teeth. When in operation, each cutter tooth cuts off the allowance of the workpiece intermittently in sequence. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces, cutting workpieces, etc. on milling machines. The chip grooves in the cutting edges of the common milling cutter are smooth, so that the chip is discharged. However, this design has a low chip capacity of the junk slots, which is disadvantageous for rapid machining of the component.

Disclosure of Invention

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: the utility model provides a special-shaped groove milling cutter, includes handle of a knife and cutting edge, the bottom of handle of a knife is equipped with the cutting edge, the week cutting edge width of cutting edge is 1 millimeter, be equipped with a plurality of recesses in the smooth junk slot in the cutting edge, the bottom center department of cutting edge is equipped with central cutting edge, the bottom surface and the side junction of cutting edge are equipped with the circular arc.

Preferably, the whole of the knife handle is cylindrical.

Preferably, the cross-sectional diameter of the shank is 10 mm.

Preferably the sum of the lengths of the shank and the blade is 75 mm.

Preferably, the radius of the circle where the circular arc is located is 0.6 millimeter.

The bottom of the cutter handle of the special-shaped groove milling cutter is provided with the cutting edge, the smooth chip removing groove in the cutting edge is provided with the plurality of grooves, the chip containing space of the chip removing groove is enlarged by the grooves, and the grooves can be used for temporarily storing chips, so that the processing efficiency of a product is not affected, the center of the bottom end of the cutting edge is provided with the center cutting edge, and the center cutting edge can enable the cutting edge to be rapidly pushed. In a word, this dysmorphism slot milling cutter, structural design scientific and reasonable, rong Rong bits space is big, has improved the efficiency of work piece shaping processing, is fit for using widely.
