Grinding Wheels Discs Abrasives - CRATEX Abrasives

In case you are working on a hard material, you'll probably want to use a softer grade and a fine-grit wheel, as hard materials resist the drilling of the abrasive grains into the surface, which dulls them quite quickly. The combination of a finer grit and a softer grade would be perfect, as the grains will dull, break away and leave.

It is the grain which decides the size of a physical abrasive in any wheel. Though a grain which is of greater size cut swiftly without any strain, we would still be able to get only a poor finish of surface. To get a fine & precision surface finish make use of ultra-fine sized grain. Wheel bonding agent is what decides how a wheel.

Dhiru said: (Aug 31, 2014). Coarse grained abrasive are used for fast removal of materials and fine grained wheel are used for finish of work. Coarse grained for grinding soft materials and fine grained for hard and brittle materials. Chirag Gotecha said: (Jul 12, 2015). But it should be depend on the surface finishing required.

Grinding - SME

movement of the workpiece or workpieces using the grinding wheel face. Workpiece surfaces produced by grinding are influenced by the following factors: • workpiece material - harder materials allow finer finishes. • type of wheel - fine grains yield finer finishes. • wheel condition - clogged wheels cannot produce a good.

Dressing of fine grained diamond grinding wheels for ultra precision .

The manufacturing of structured molds calls for alternatives in terms of grinding wheel geometry and dressing. To manufacture geometric features in the micron range on molds, sharp edged fine grained grinding wheels can be used. A dressing procedure with metal alloy blocks is used to create sharp edged grinding.

Is a grinding technique, used for many years, which allows to “dig” or carve the glass. It is carried out in several phases: The first phase involves the use of a very rough grinding wheel consisting of coarse-grained silicon carbide; the second a fine grain grinding one; the third a natural sandstone wheel, which removes all.

Product introduction | SHIN-EI Grinding Wheels MFG. Co.,Ltd.

We consider resinoid bond to be the optimal bonding agent for affixing fine abrasive grains, because it enables more uniform dispersion of abrasive grains in comparison to other bonds. Building upon these ideas, SHIN-EI GRINDING WHEELS MFG. CO., LTD. has developed and manufactured high speed roll grinding.
