Abstract

This utility model one variable density micro-texture self-lubricating cutter, mainly it is made up of point of a knife, knife face, groove and kollag, carbide tool rake face is carried out laser micro-texture moulding, machined the micron order groove texture of uniform density micron order groove texture and different densities combination, it is high density near point area, is low-density away from point area.And in micro-texture, fill kollag.Simple in construction is provided the benefit that by technique scheme, tool surface texture can be as the memory space of lubricant, contribute to lubricant and quickly spread over cutter bits contact surface, cutter bits mantle friction contact condition can be effectively improved, reduce cutting force, cutting temperature, suppression tool wear, effectively increases the service life, and improves workpiece processing quality and efficiency.

Description

Variable density micro-texture self-lubricating cutter

Technical field

This utility model relates to numerically controlled lathe field, particularly relates to a kind of variable density micro-texture self-lubricating cutter.

Background technology

Pure iron, as the most special a kind of ferrous metal, has excellent toughness, plasticity and electromagnetic performance, has been increasingly becoming the material base of a lot of high-tech industry.But it is the highest to be also due to its plasticity simultaneously, during machining, plastic deformation is big, processing hardening easily occurs, and chip simultaneously easily bonds rake face, causes the highest cutting temperature and bigger cutting force.Chip deformation is big, and cutter-bits contact length is big, and is difficult to curling and fractures, and easy and rake face generation cold welding, easily produces built-up edge, " viscous cutter " phenomenon easily occurs, and in working angles, tool wear is more serious, and its difficulty of processing is the biggest.

Utility model content

The purpose of this utility model is to provide a kind of variable density micro-texture self-lubricating cutter, to solve that existing cutter structure is complicated, crudy and efficiency is low, service life is short problem.

The technical solution of the utility model is:

A kind of variable density micro-texture self-lubricating cutter, is made up of point of a knife, knife face, groove and kollag, and described point of a knife is connected with knife face solid, arranges groove near point of a knife, and groove disposes kollag.

Described point of a knife is to be made up of heavy alloy material.

Described knife face is to be made up of low-density alloy material.

The beneficial effects of the utility model are: a kind of variable density micro-texture self-lubricating cutter, simple in construction, tool surface texture can be as the memory space of lubricant, contribute to lubricant and quickly spread over cutter bits contact surface, cutter bits mantle friction contact condition can be effectively improved, reduce cutting force, cutting temperature, suppress tool wear, effectively increase the service life, improve workpiece processing quality and efficiency.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model；

1-point of a knife；2-knife face；3-groove and 4-kollag.

Detailed description of the invention

As shown in Figure 1, this utility model variable density micro-texture self-lubricating cutter is mainly made up of point of a knife 1, knife face 2, groove 3 and kollag 4, carbide tool rake face 2 is carried out laser micro-texture moulding, machined the micron order groove texture of uniform density micron order groove texture and different densities combination, it is high density near point of a knife 1 region, is low-density away from point of a knife 1 region.And in micro-texture, fill kollag 4.

Certainly, technique scheme is preferred forms of the present utility model, and any improvement made under without departing from spirit background of the present utility model, within all falling within protection domain of the present utility model.
