Embodiment Construction

[0016] The present invention will be further elaborated below with reference to the accompanying drawings.

[0017] A grooved wheel, the material components of which include: copper-tin alloy powder, silver powder, polyimide resin powder, the components are: copper-tin alloy powder 70% to 95%; silver powder: 3 %~10%; polyimide resin powder: 1%~6%.

[0018] see figure 1 , a method of manufacturing a grooved wheel, comprising the following steps:

[0019] The first step S1 is to prepare a composite binder: mix copper-tin alloy powder, silver powder, and polyimide resin powder according to weight percentage: copper-tin alloy powder: 70%-95%; silver powder: 3%-10%; polyimide resin powder: 70%-95%; silver powder: 3%-10%; Resin powder: 1% to 6%, placed in a mixer and mixed for 20 to 60 minutes. Wherein, the mixer is a three-dimensional mixer.

[0020] In the second step S2, add abrasives and continue mixing for 50-120 minutes. Abrasives are steel balls to aid in mixing, and the...

Abstract

The invention provides a slotted wheel. Manufacturing material components of the slotted wheel comprise copper-tin alloyed powder, sliver powder and polyimide resin powder, and the components comprise, by weight, 70%-95% of the copper-tin alloyed powder, 3%-10% of the silver powder and 1%-6% of the polyimide resin powder. The slotted wheel is good in heat resistance, long in service life, high in sharpness, great in cutting capacity and high in material removal rate, the processing work cycle can be shortened, the quality of the workpiece surface is good, and no burn or crack occurs.

Description

technical field [0001] The invention relates to the technical field of grinding tools, in particular to a grooved wheel and a manufacturing method thereof. Background technique [0002] The powerful grooved wheel has the characteristics of high grinding efficiency, good surface finish and low cost. Mainly through the high hardness, high thermal conductivity and high sharpness of diamond and CBN to achieve high grinding efficiency, it is suitable for high hardness materials such as cemented carbide, high-speed steel, ferrite, ceramics, quartz, and refractory materials. However, the current grooved wheel is made of resin bond, which has good self-sharpening and high grinding surface quality, but has poor heat resistance and short life; metal bond grinding wheel has high strength, good life and heat resistance. , but less sharp. Contents of the invention [0003] The purpose of the present invention is to provide a grooved wheel and its manufacturing method, which solves th...
