Formed cutter

Abstract

A formed cutter comprises a handle, a cutter neck attached to the handle and a cutterhead arranged at the end of the cutter neck. The cutterhead comprises a joint face which faces one side of the cutter neck and is connected with the end of the cutter neck, an outer circumferential surface and an end surface which is arranged opposite to the joint face and far from the side of the cutter neck. At least one cutting groove, which extends from the position wherein the joint face is connected to the cutter neck to the end surface of the cutterhead, is concavely arranged on the cutterhead. According to the formed cutter provided by the invention, a product's curved surface, flat surface and transition surface of the curved surface and the flat surface can be moulded by primary processing. The cutting edge of the formed cutter is shaped as an arc curved surface, thereby effectively increasing cutting area and raising work efficiency of the formed cutter. In addition, as the cutter edge's curved surface structure for milling matches the product's curved surface structure, machining accuracy can effectively raised, and the product quality is guaranteed.

Description

Technical field [0001] The invention relates to a milling cutter, in particular to a forming milling cutter that can process a formed curved surface and a plane at one time. Background technique [0002] At present, users are increasingly demanding on the appearance of electronic products such as touch tablet computers and touch screen mobile phones, and hope that the appearance of new products partially presents more and more curved 3D effects. When traditionally processing the above-mentioned products with the partial surface 3D effect of the curved surface and the plane coexisting, the ball knife processing is usually used to form the above-mentioned curved surface. However, the cutting edge shape of the ball knife does not match the processing shape of the product, resulting in low processing accuracy. In addition, since the cutting edge of the ball cutter is linear and the cutting area is small, it takes a lot of man-hours to process the shape into a preset appearance, and t...

AI Technical Summary

Problems solved by technology

Traditionally, when processing the above-mentioned products with local curved surface 3D effects and the coexistence of curved surfaces and planes, ball cutters are usually used to shape the above-mentioned curved parts. However, because the shape of the cutting edge of the ball cutter does not match the shape of the product, the processing accuracy is not high.

In addition, because the cutting edge of the ball cutter is linear and the cutting area is small, it takes a lot of man-hours to process and form the preset appearance shape, and the work efficiency is low

For electronic products that need to be produced in large quantities, it will undoubtedly affect product quality and production progress
