Test method for testing cutting performance of diamond saw blade

Abstract

The invention belongs to the technical field of diamond tool testing, and discloses a test method for testing the cutting performance of a diamond saw blade, which solves the problem in the prior art that existing test methods for testing the cutting performances of diamond cutters are not accurate and not uniform. The test method comprises the following steps of 1, obtaining a set load parameter value: controlling the feed quantity of a diamond saw blade, finding a load value K of the diamond saw blade when the feed quantity of the diamond saw blade on a cutting object is maximal, and setting M= 0.70K-0.85K, wherein M is the set load parameter value; 2, during the cutting process, controlling the cutting load value of the diamond saw blade to be 0.9M-1.1M by means of a servo system. According to the technical scheme of the invention, the unification of three cutting elements, namely a machine tool, an object and a feed thrust, is realized. Meanwhile, the cutting performance of a diamond cutter can be automatically and accurately tested. Therefore, a unified and standard testing standard is formed for the industry and the perfect development of the diamond tool industry is ensured.

Description

technical field [0001] The invention belongs to the technical field of diamond tool testing, and in particular relates to a testing method for the cutting performance of a diamond saw blade. Background technique [0002] The national standard "GB / T11170 Diamond Circular Saw Blades for Superhard Abrasive Products" is one of the technical standards with a certain level of technical standards in the field of superhard tools in my country in line with international standards, but there is no "cutting" for the actual performance of diamond circular saw blades. "performance" is an important characteristic to make qualitative or quantitative specifications. [0003] The cutting performance of the diamond circular saw blade is the core performance index of the diamond circular saw blade. The cutting performance of the saw blade is determined by the performance of the actual cutting of a specific object in terms of speed, load, consumption, tailing, edge effect and other indicators. ...

Problems solved by technology

[0009] In order to solve the inaccurate and inconsistent testing methods of existing diamond saw blade cutting performance, diamond grinding wheel grinding performance and diamond drill bit drilling performance, the present invention provides a test method for diamond saw blade cutting performance. It forms an accurate, sensitive and reliable control and test system with the programmable logic controller (PLC), skillfully establishes a dynamic closed-loop servo mode in the cutting process, and adjusts the cutting speed in a timely manner, which not only stabilizes the cutting load (that is, the cutting force) Adapt to the condition of uneven structure of cutting materials and uneven performance of saw blade working teeth, make the saw blade work in the best state, realize intelligent cutting, and realize automatic measurement of various parameters, so as to accurately obtain the working conditions of the diamond saw blade performance

It not only realizes the flexible and intelligent cutting test, but also solves the problem of large differences in manual pushing and cutting.
