Grinding wheel for grinding large contact surface

Abstract

The invention discloses a grinding wheel which has large contact surface and can be used for grinding, comprising a grinding wheel body and is characterized in that the outer circumference of the grinding wheel is evenly provided with a set of slots used for removing chips and dissipating heat. As the slots are arranged on a grinding surface of the grinding wheel, the grinding lengths of the grinding wheel and workpieces are simultaneously shortened, and cooling fluid flows into grinding area through the slots to cool and lubricate the grinding surface, thus solving the problem that the grinding surface is burnt, increasing the quality of the grinding surface without the reduction of grinding efficiency. The parts along the axial direction of adjacent slots are overlapped, thus the length where the grinding wheel is contacted with workpieces is even and stable grinding can be ensured. The included angel alpha formed by grinding wheel axis lines is 45-55 degrees. The relationship between include angle alpha of grinding wheel diameter D, width B, the slots and the axis lines and the number of the slots N can be described as N=(arc sin(B* tg alpha / D)).

Description

technical field [0001] The invention relates to a grinding wheel for grinding, which belongs to the technical field of parts processing, in particular to a grinding wheel used in the plunge-cut forming grinding process, in particular to a grinding wheel for large contact surface grinding. Background technique [0002] Usually, in the plunge-cut form grinding process, the form grinding wheel is moved towards the workpiece in a given direction, and the desired shape is ground on the surface of the workpiece. If during the grinding process, the contact area between the grinding wheel and the workpiece is relatively large, it is easy to produce vibration marks, and the temperature of the grinding surface is high at the same time. At this time, the cutting fluid cannot enter the grinding area to cool the workpiece in time, which can easily cause burns on the grinding surface and seriously affect the quality and performance of the workpiece. [0003] In order to avoid the burn of...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problems of the existing grinding technology or the workpiece is easy to be burned or the grinding efficiency is very low, and the grinding surface quality is poor. It provides a novel grinding wheel, which aims to ensure the grinding efficiency and Effectively avoid workpiece burns while maintaining processing quality

[0006] In the present invention, a set of chip removal and heat dissipation chute is provided on the grinding surface of the grinding wheel, so that the grinding length of the grinding wheel and the workpiece is reduced at the same time, and at the same time, the coolant enters the grinding area through the chute to cool and lubricate the grinding surface. Solve the problem of grinding surface burns, improve the quality of the grinding surface without reducing the grinding efficiency
