These grind extremely hard materials, with CBN working on hard steels for precise profiles and finishes, and synthetic diamond working on hard nonferrous material like tungsten carbide and cermets. Superabrasives can be used for both roughing and surface finishing, depending on the grit size involved.

Grinding at shallow angles can prolong the wheel's lifespan, but it also often compromises the cut-rate. On harder materials, shallow grinding angles may also increase unwanted vibration and chatter. TYPE 28. Type 28 grinding wheels, also known as saucer wheels, have similarly depressed centers and are optimized for low grinding angles.

For materials that are hard to grind, we will want to use a mild/friable grain, which fractures more easily, stays sharper, and actually grinds the material. For easy to grind materials, we would want a coarser grit. This is because the grain can easily penetrate the material, make and remove chips.

بیشتر

The hardness of the material governs the amount of penetration that can be achieved by the abrasive. For this reason, finer grit sized wheels are required to grind hard materials and soft materials are best ground with medium to coarse grit size wheels. For most efficient operation, the grade must be adjusted to suit the hardness of the material.

Further, you should use grinding wheels with coarse grains for soft material and a grinding wheel with fine grains for hard material. Type of Bond. Bond is the material used for cementing together the abrasive grains in your grinding wheel; bonding materials in use are Vitrified bond, silicate bond, rubber bond, resinoid bond and metallic bond.

Grinding is the first step of mechanical material removal. Proper grinding removes damaged or deformed surface material, while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in the shortest possible time.

بیشتر

Each grinding step, while producing damage itself, must remove the damage from the previous step. The depth of damage decreases with the abrasive size but so does the metal removal rate. For a given abrasive size, the depth of damage introduced is greater for soft materials than for hard materials.

Grinding crosswise causes arc wander and risk inclusions in some applications. Since tungsten is a very hard material, grinding wheels should be made of diamond or borazon. Electrodes should be cut using a cutting wheel where possible.

Like grinding, hard turning in some materials can produce a "white layer" or amorphous zone on the surface of the workpiece. This surface defect is invisible to the eye and must be measured using instruments. The white zone usually forms in hard turning because the cutting tool is dull and, hence, delivers too much heat to the workpiece ...

Grinding also works better than milling on very hard materials. Turning machine manufacturers may claim their equipment can achieve a surface finish of Ra 8 µin (0.20 µm) to Ra 16 µin (0.41 µm), depending on the tools, speeds, and feeds.

The selection of abrasives for the grinding wheels are depends on the material type of the work piece. On grinding wheel specifications abrasives is represented by an alphabetic character. If we consider three basic types of work materials i.e. very hard, hard and soft or medium then for each category different types of abrasives are used.
