1. ABRASIVES PRESENTED BY: DR. HASHMAT GUL DEMONSTRATOR, DENTAL MATERIALS, AMC, NUST. 2. SOME IMPORTANT DEFINITIONS ABRASIVE A hard substance used for grinding, finishing, or polishing a less-hard surface. CUTTING Process of removing material from the substrate by use of a bladed bur or an abrasive embedded in a binding matrix on a bur or disk.

An embedded abrasive is a loose abrasive particle pressed into the surface of a specimen. With soft materials, abrasive particles can become embedded. Embedded abrasives can occur because of a small abrasive particle size, the grinding or polishing cloth used has a low resilience, or a lubricant with a low viscosity is used.

Grinding Wheel is generally composed of two types of materials. One is the abrasive cutting compound used for grinding in Industrial applications. The other is the bond formed between the abrasives. A grinding wheel performs several operations in the grinding and the abrasive machining. Grinding wheels are used in grinding machines.

What are 3 different sizes or types of grit? Sandpaper- 30-160 Polishing- 180-240 Please go to Home Depot or and find several options for bench grinding wheels.

These bonds are prepared by mixing abrasives with synthetic resins like backelite and redmanol and other compounds. Mixture is moulded to required shape and baked upto 200°C to give a perfect grinding wheel. These wheels have good grinding capacity at higher speed. These are used for precision grinding of cams,

GRINDING Abrasive machining: •The oldest machining process - "abrasive shaping"at the beginning of "Stone Era". •Free sand was applied between two moving parts to remove material and shape the stone parts. Grinding: •Removing of metal by a rotating abrasive wheel.(Very high speed, Shallow

The milder abrasives like 32 and 38 Aluminum Oxide are best for lighter precision grinding operations on steels and semisteels, while the intermediate 57 and 19 Aluminum Oxide abrasives are used for precision and semiprecision grinding of both mild and hard steels. The severity of the grinding operation also influences the choice of grade.

Abrasive machining involves material removal by the action of hard, abrasive particles. The use of abrasives to shape parts is probably the oldest material removal process. They are important because Introduction They can be used on all types of materials ranging from soft metals to hardened steels and hard nonmetallic materials such as
