Embodiment 1

[0024] Such as figure 1 The composite milling cutter for graphite slotting shown has a cutter shaft and a multi-piece milling cutter. There is a keyway on the cutter shaft. The milling cutter is connected to the cutter shaft through a key. It has a cutter shaft and 18 pieces are sequentially set and connected to the cutter shaft. Milling cutter, the milling cutter is a three-sided edge milling cutter, each milling cutter has 4-8 cutter heads; one end of the cutter shaft is fixedly connected with a drive turntable, and the other end of the cutter shaft is connected with a bearing supporting the cutter shaft;

[0025] There is a spacer ring between each milling cutter to adjust the spacing and positioning between milling cutters; each milling cutter has a set rotation angle of 10°-20° relative to adjacent milling cutters.

[0026] The diameter of each milling cutter at the two ends of the cutter shaft is smaller than that of the milling cutters at other positions.

[0027] The ...

Abstract

The invention provides a combined milling cutter used for graphite grooving. The combined milling cutter comprises a cutter shaft and 4-20 milling cutter bodies sequentially connected to the cutter shaft in a sleeving mode. Each milling cutter body comprises 4-8 tool bits. One end of the cutter shaft is fixedly connected with a drive rotating plate, and the other end of the cutter shaft is connected with a bearing supporting the cutter shaft. Positioning space rings are arranged between the milling cutter bodies so that the distances between the milling cutter bodies can be regulated. Each milling cutter body has a sleeving rotation angle ranging from 5 degrees to 30 degrees relative to the adjacent corresponding milling cutter bodies. The diameters of part of the milling cutter bodies are different. The front angle of the tool bit of each milling cutter is 8-12 degrees, the rear angle of the tool bit of each milling cutter is 18-22 degrees, and the tool bits are made of hard alloy. The combined milling cutter is rapid in grooving speed and good in grooving quality, and 4-20 grooves can be synchronously formed.

Description

technical field [0001] The invention relates to a tool for making grooves on the surface of a board. Background technique [0002] Grooving on the surface of metal parts usually uses end mills or saw blade milling cutters. Lettering or engraved lines on the surface of glass materials usually use corrosion or sandblasting process. Grooving on the surface of graphite materials used to be treated similarly to metal materials, which tends to crack easily. Or the phenomenon of broken, and the slotting speed is slow, especially the multiple parallel slots can only be opened one after another, which is inefficient. [0003] The utility model with the patent application number 2012200645370 relates to an eccentric inner groove boring tool, including: a movable handle, a cutter head and an eccentric sleeve integrated with the handle; the rear end of the movable handle is sleeved on the In the above-mentioned eccentric sleeve, the gap between the movable handle and the eccentric slee...
