Cutting tool and milling cutter arbor for mounting cutting tool

Abstract

The invention relates to a cutting tool, which comprises a cutting tool body and a cutting part, wherein the cutting tool body is connected with the cutting part by welding, and the cutting part is made of an alloy material. The invention also relates to a milling cutter arbor. Milling cutter slots are uniformly arranged on the surface of the milling cutter arbor spirally; a screw hole is formed on the milling cutter arbor by clinging to the milling cutter slots; and the screw hole is formed by having an angle relative to the milling cutter slots. The cutting tool disclosed by the invention can realize cyclic utilization, save cost, and is firmer and more convenient to mount by matching with the special milling cutter arbor.

Description

technical field [0001] The invention relates to a cutting tool and a milling cutter rod used for installing the cutter, in particular to a cutting tool with high cutting strength and a milling cutter rod which is easy to install. Background technique [0002] Cutting tools are commonly used tools for cutting in mechanical manufacturing. Since the tools used in mechanical manufacturing are basically used to cut metal materials, cutting tools are required to have high strength. [0003] On the one hand, the existing cutting tools on the market are generally divided into two parts, namely the metal body and the cutting edge. The bond between the metal body and the cutting edge is generally divided into two types. First, in order to shorten the manufacturing process, the metal body and the cutting edge are generally integrally formed. In this case, when the cutting edge has been used for too long or the intensity of use is too high, and when there is a curl or a gap, the enti...

AI Technical Summary

Problems solved by technology

In this case, when the cutting edge has been used for too long or the intensity of use is too high, and when there is a curl or a gap, the entire cutting tool can only be discarded instead of being recycled, resulting in waste of cost; second, the metal body The connection between the cutting edge and the cutting edge is screwed, which makes the work of replacing the cutting edge more complicated

[0004] On the other hand, the existing milling cutter bar or milling cutter disc for installing cutting tools usually uses screws to pass through the tool body to fix it to the milling cutter bar or milling cutter disc. When multiple cutting tools need to be installed, Using this traditional installation method requires multiple screw tightening actions, and the operation space is small, time-consuming and labor-intensive, which affects work efficiency
