High stock removal

Grinding with coated abrasives has recently become a viable alternative for high stock removal through developments in machine tool and grinding belt technology.. Belt grinding with coated abrasives can be an attractive process because the large surface area of the recirculating belt tends to carry away heat and prevent local hot spots.

How to choose the grinding wheels for stainless steel

Dec 07, 2021Resin bond grinding wheels are used for stainless steel cutting, grooving, and centerless grinding. It has high strength, good elasticity, shock-free and many porous and can be used for high peripheral speed (35-75m/s). But resin bond grinding wheels have low hardness. If put the resin grinding wheel into the paraffin wax, it can prevent the

Fluid performance study for groove grinding a nickel

The performance of three water-based grinding fluids was analyzed and compared to a neat oil tested under the same process conditions. Light optical and scanning electron microscopy observations show the mechanism of metal deposition that leads to CBN wheel failure for water-based fluids. To improve the performance of the water-based fluids, a new nozzle layout is proposed that would prevent
