Description

Cutter for milling groove and plane simultaneously

Technical Field

The utility model relates to a cutter of milling flutes.

Background

The groove milling cutter in the prior art is a common disc-shaped milling cutter for milling grooves, generally speaking, the groove milling process of the groove milling cutter is a milling cutter with a groove milling blade which moves downwards to complete the milling process, the blade generally has milling of a lower end face and a side end face, and in the milling process, due to the limitation of a cutter, the milling shape and the milling function are single, so that the groove milling efficiency of the conventional groove milling cutter cannot be adapted.

Disclosure of Invention

In order to overcome the not enough of present milling flutes cutter milling speed slow, the utility model provides a milling flutes cutter that milling speed is fast.

The technical proposal of the utility model for solving the technical problem is that: a cutter for milling grooves and planes simultaneously comprises a cutter handle, wherein a cutter holder is arranged at the lower end of the cutter holder, a central column and an outer side ring are arranged at the lower end of the cutter holder, a first cutter set surface, a second cutter set surface and a third cutter set surface are uniformly arranged on the central column and the outer side ring along a rotating center, a first cutter set is arranged on the first cutter set surface, a second cutter set is arranged on the second cutter set surface, and a third cutter set is arranged on the third cutter set surface; the first cutter set comprises an inner edge cutter blade arranged on the lower corner of the central column and an outer edge cutter blade arranged inwards on the outer side surface ring; the second cutter set comprises end plane blades positioned on the outer lateral ring; the third cutter group comprises an inner chamfering blade positioned at the upper end of the edge of the central column and an outer chamfering blade positioned on the outer side ring.

Furthermore, the end plane blade is provided with two blades, one blade is arranged on the central column and the other blade is still arranged on the outer side ring, and the other blade is arranged in front of the central column.

Further, the inner insert is configured to cut at a first cutting corner depending from the underside, and the outer insert is configured to cut at a second cutting corner depending from the extension of the outer insert.

Further, the blades adopted in the first cutter set and the second cutter set are diamond-shaped blades.

The utility model discloses carry out the cubic cutting at first knife tackle face, second knife tackle face, third knife tackle face respectively when using to accomplish the interior limit of groove, outside, interior limit chamfer, outside chamfer, the planar cutting of end, accomplish the cutting work to whole chamfer groove.

The beneficial effects of the utility model reside in that: 1. the groove milling cutter is provided with a plurality of cutter sets, the inner edge, the outer edge, the upper end face edge, the inner chamfer and the outer chamfer are cut in three steps by the groove milling cutter, and the groove milling cutter is high in cutting speed and efficiency. 2. The cutting of the end face edge is divided into a front cutter and a rear cutter, and the chip removing performance in the cutting process is excellent.
