Description

Wear-resisting type spiral reamer

Technical Field

The utility model relates to a spiral reamer technical field particularly, relates to a wear-resisting type spiral reamer.

Background

The reamer has one or more cutter teeth, a rotary cutter for cutting off a thin layer of metal on the surface of a machined hole, and a rotary finishing cutter with a straight edge or a spiral edge, and is used for reaming or repairing the hole. The reamer is used for reaming drilled (or reamed) holes on a workpiece, mainly for improving the machining precision of the holes and reducing the roughness of the surfaces of the holes, is a tool for finish machining and semi-finish machining of the holes, and generally has small machining allowance. Reamers for machining cylindrical holes are commonly used. The reamer used for processing the tapered hole is a tapered reamer and is less in use. The manual reamer and the machine reamer can be seen according to the using condition, and the machine reamer can be divided into a straight shank reamer and a taper shank reamer. The hand is straight shank type. With the increasing severity of the service environment of the current materials, the traditional reamer can not meet the strict performance requirements, so that the development of novel protective coating materials is urgently needed. Higher requirements are put on the properties of the coating material such as hardness, friction and wear resistance and the like. If the coating on the surface of the reamer has the performances of high hardness and low friction coefficient, the working stability of the reamer can be ensured, the working efficiency is improved, and the service life of the reamer is prolonged.

An effective solution to the problems in the related art has not been proposed yet.
