surface grinding wheels: types and specification

surface grinding wheels: types and specification

On a surface grinder, the abrasive grinding wheel that spins at very high speed removes material from the workpiece surface that is fed against the wheel. How are the abrasive wheels made and what are the specifications of the grinding wheel? Lets take a detailed look at the surface grinder wheel.

A grinding wheel contains abrasive grains of a selected size held together by a bonding agent. However, the complete volume of the grinding wheel is not filled with abrasive grains and bonding element and this result in gaps between the abrasive grains and bonding element and they are called pores.

The abrasive grain in your grinding wheel has a unique quality called friability; friability is the capability of the abrasive grain to get fractured under heavy cutting forces to improve its ability to cut.

Your objective of using a grinding wheel as a tool is to get a high-quality surface finish, precision geometric accuracy (up to within 0.0025 mm tolerance), and its ability to grind hardened surfaces, carbide, and ceramic. The performance of your grinding wheel in terms of material removal rate and surface finish depends on the type and size of abrasive grains, type of bonding material, and pores or empty space between the abrasive and the bonding material. Come, let us consider each of the following factors.

You can use the grinding wheels of aluminum oxide, silicon carbide, cubic boron nitride, and diamond as under: Type of abrasive Knoop Hardness Typical Usage Aluminum oxide. 2100 HK Ductile materials like steel and other high alloy materials. Can be used for cast-iron also. Silicon carbide. 2400 HK Cast-iron, aluminum, copper, and brass. Cubic boron nitride. 5000 HK Hardened tool steels and cemented carbides. Diamond (synthetic or poly crystalline diamond). 6000 HK Glass, ceramic, and cemented carbide tools.

The grinding wheel grain size controls the possible amount of depth of cut. Bigger grain size protrudes more on the grinding wheel periphery or face resulting in a higher depth of cut and smaller grains protrudes less resulting in a lower depth of cut. Hence the size of the chip is fine in the case of smaller grain size wheels.

The grain size in your grinding wheel is classified as coarse 8-30, medium 30-60, fine 70-180 and very fine 200-600. The material removal rate will be more for your grinding wheel with coarse abrasives and less for a wheel with fine abrasives; also grinding wheels with fine or very fine abrasives gives a better finish compared to the grinding wheels with medium or coarse grains. Further, you should use grinding wheels with coarse grains for soft material and a grinding wheel with fine grains for hard material.

Vitrified bond (V) The majority of your grinding wheels used in industries are of vitrified bond and it is a combination of clay and ceramic. Your grinding wheel with vitrified bond has good strength, thermal stability and can run up to 2000 meters per minute speed; it is inert to oil and water and good for wet grinding.

Silicate bond (S)-Your grinding wheel with silicate bond has silicate of soda and is used for grinding operations where the heat generated by grinding is to be kept to a minimum, like grinding of hardened tool material.

The grade of your grinding wheel indicates the strength of the bonding material with the abrasive grains and also how firmly the bond holds the abrasive grains. The grade of your grinding wheel is also referred to as the hardness of the wheel. Grade of the grinding wheel is indicated by alphabets A to Z; A indicates Soft Grade; M indicates Medium Grade and Z indicate Hard Grade.

You use the hard grade Grinding Wheel for grinding soft materials and soft grade grinding wheels for grinding hard materials; also you use hard grade for high material removal rate (low surface finish) and soft grade for low material removal rate (high surface finish).

You use grinding wheels with an open structure for high material removal rate (soft material and low surface finish) and grinding wheels with a dense structure for low material removal rate (hard material and high surface finish).

Since the grinding wheel of your machine rotates at high rpm, even slightly out-of-balance conditions may give rise to high vibrations and results in poor surface finish, faster wheel wear-out, and can even be dangerous to the operator.

tormek 10" fine 600 grit diamond wheel for t7/t8

The Tormek diamond wheels have abrasive on the side of the wheel too. When used in conjunction with the MB100 Multi Base, this flat face can be used with 10 different Tormek jigs for sharpening. If you need a flat bevel instead of the slight concave surface that edge-of-wheel sharpening gives, it is now possible to achieve it on a Tormek.

For the best results, Tormek recommends using water when sharpening with their diamond wheels. And included with each diamond wheel is a 150ml bottle of TOR-ACC150 Anti Corrosion Concentrate. Mix 10ml of concentrate per 250ml of water in the trough for non-corrosive, water cooled sharpening.
