Grinding machine, diamond tool and machining method of diamond tool

Abstract

A diamond tool is used for grinding a to-be-machined workpiece, and comprises a main body and a diamond particle fixed to one end of the main body; one end of the main body is provided with a concavegroove; the diamond particle comprises a fixing part and a grinding part formed by extending from the fixing part; the fixing part is stored and fixed to the concave groove; the grinding part is exposed out of the concave groove and used for grinding the to-be-machined workpiece, the profile arithmetical mean deviation Ra, the profile maximum height Ry and the microcosmic irregularity ten-point height Rz of the grinding part meet the relation that Ra is smaller than 0.124 [mu]m, Ry is smaller than 1.306 [mu]m, and Rz is smaller than 0.757 [mu]m. The invention further provides a grinding machine and a method for manufacturing the diamond tool. According to the diamond tool, the grinding machine and the method for manufacturing the diamond tool, flexible grinding is conducted through an airflotation shaft and an air flotation platform, thus, the obtained diamond tool meets the design requirements for the appearance and size and has the characteristics of being smooth in arc and free oflines, meanwhile, the machining yield reaches 99% or above, and one diamond tool can machine 600 to-be-machined workpieces.

Description

technical field [0001] The invention relates to a grinding machine, a diamond cutter and a manufacturing method thereof. Background technique [0002] Diamond has extremely high hardness, high thermal conductivity and low thermal expansion coefficient. It is the best material for making cutting and grinding tools and is widely used. Diamond tools made of diamond have the advantages of high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals, and can be used for non-metallic hard and brittle materials such as Precision machining of graphite, high wear-resistant materials, composite materials, high-silicon aluminum alloys and other tough non-ferrous metal materials. [0003] In the prior art, diamond is usually processed by rigid grinding technology, but the surface of the diamond tool manufactured by rigid grinding is rough, the arc contour is smoo...

Problems solved by technology

[0003] In the prior art, diamond is usually processed by rigid grinding technology, but the surface of the diamond tool manufactured by rigid grinding is rough, the arc contour is smooth and there are obvious horizontal lines, while the diamond tool manufactured by rigid grinding is It will vibrate and bounce the knife from time to time, so that the workpiece will be worn out quickly, and the final size of the workpiece is difficult to guarantee
