Abstract

The invention provides an evaluation method for processing characteristics of a diamond pellet. The method comprises the following steps: 1) setting a characteristic index system of the diamond pellet, wherein the characteristic index system comprises integral rigidity and microscopic hardness, the integral rigidity characterizes shape preserving ability of the pellet during processing of a workpiece and the microscopic hardness characterizes influence of the pellet on surface quality of the workpiece during processing, presetting rigidity thresholds used for dividing grades of the integral rigidity and presetting hardness thresholds used for dividing grades of the microscopic hardness; 2) carrying out constant-speed loading on a to-be-evaluated diamond pellet by using a pressure testing machine, measuring a pressure-deformation curve, calculating the integral rigidity, and comparing the calculated integral rigidity with the rigidity thresholds used for dividing grades so as to obtain the grade of the integral rigidity; and 3) detecting the microscopic hardness of the to-be-evaluated diamond pellet and comparing the detected microscopic hardness with the hardness thresholds used for dividing grades so as to obtain the grade of the microscopic hardness. The method provided by the invention prevents statistics through a great number of experiments and has good rapidity.

Description

technical field [0001] The invention relates to the technical field of grinding processing, in particular to a method for evaluating the processing characteristics of diamond pellets. Background technique [0002] In the grinding process, diamond pellets are used as fixed abrasives, and are widely used in the grinding process of brittle materials such as optical glass, ceramics, and gemstones. Different factors such as diamond pellet binder, diamond powder concentration and other factors affect the surface shape accuracy and surface roughness of the workpiece after processing. Generally, the surface shape accuracy of the workpiece processed by diamond pellets with a harder binder is better, but the surface roughness is poor. The surface roughness of the workpiece processed by diamond pellets with a softer binder is better, but the surface shape accuracy is poor. There is a large range of variation in the measured surface accuracy and surface roughness of the processed work...
