Problems solved by technology

[0004] As industrial production has higher and higher requirements for efficiency, cleanliness and environmental protection, the processing efficiency of ordinary corundum grinding wheels is low, the dressing interval is short, and the service life of the grinding wheel is low. Fast wear and tear, the grinding fluid needs to be replaced frequently, and the pollution is large

Embodiment 1

[0024] A special CBN grinding wheel for stainless steel flat grinding, the raw material formula and the distribution ratio of each component are shown in the following table:

[0025] components Phenolic resin powder CBN Silicon carbide copper powder White corundum Foaming agent Proportion / wt %

22 30 15 20 10 3

[0026] Among them, the particle size of CBN is 76 microns, the particle size of foaming agent is 20 microns, the particle size of white corundum is 30 μm, the particle size of silicon carbide is 20 μm, and the particle size of copper powder is 30 μm.

[0027] The specific pressing process is as follows:

[0028] Mix phenolic resin powder, silicon carbide powder, copper powder, white corundum powder and foaming agent according to the above ratio and put them in a three-dimensional mixer, mix them for 1 hour, and make them fully mixed evenly; then add the CBN abrasive into the mixed Mix the mixture in a three-dimensional mixer...

Embodiment 2

[0032] A special CBN grinding wheel for stainless steel flat grinding, the raw material formula and the distribution ratio of each component are shown in the following table:

[0033] components Phenolic resin powder CBN Silicon carbide copper powder White corundum Foaming agent Proportion / wt %

24 30 15 20 10 1

[0034] Among them, the particle size of CBN is 76 microns, the particle size of foaming agent is 20 microns, the particle size of white corundum is 30 μm, the particle size of silicon carbide is 20 μm, and the particle size of copper powder is 30 μm.

[0035] The specific pressing process is the same as in Example 1, except that the height of the die ring during pre-compression increases the volume of the die cavity by 5% to obtain a finished grinding wheel.

Abstract

The invention provides a CBN grinding wheel special for stainless steel plane grinding and a preparation method thereof. The grinding wheel comprises, by weight: 18-25% of phenolic resin powder, 25-35% of CBN, 12-18% of silicon carbide, 8-12% of white corundum, 20-25% of copper powder, and 1-3% of a foaming agent. The CBN grinding wheel is specially designed for stainless steel plane grinding andis used for replacing an existing common corundum grinding wheel. The grinding wheel is provided with uniformly distributed air holes, a designed bonding agent has weak elasticity, the sharpness can be continuously maintained when the plane of a stainless steel workpiece is ground, continuous machining is achieved without finishing, the production efficiency of grinding is improved, the use time of grinding fluid is prolonged, and the production cost is reduced. The ground stainless steel workpiece is uniform in surface texture and stable in size, and time for finishing a grinding wheel multiple times and measuring the size of the workpiece multiple times when a worker uses the common corundum grinding wheel is shortened.

Description

technical field [0001] The invention belongs to the technical field of grinding tool processing, and relates to a special CBN grinding wheel for stainless steel flat grinding and a preparation method thereof. Background technique [0002] Stainless steel is a general term for acid, alkali and salt chemical corrosion resistant steel containing Cr, Mo, Ni and other elements. There are more than 100 kinds of stainless steel used in the market, including martensitic steel and ferritic steel according to the organizational state. , Austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardening stainless steel, etc. [0003] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. With the development of the mold industry, the working environment of the mold has higher and higher requirements on th...
