Grinding Wheel Dressing Dressing may be broadly defined as any operation performed on a wheel face to change the nature of its cutting action. Why Grinding Wheel Dressing Needed? Dressing is necessary when the individual grain crystal in the wheel face become dulled and the rate of stock removal is constantly decreasing as the grinding…
Grinding Wheel Ring Test Procedure The ring test usually detects an external or internally cracked wheel. This test is applicable to vitrified and silicate wheels. Such wheels will give a metallic ring when gently tapped with a wooden mallet, preferably at about 45 degrees to the either side of the vertical center line and about…
A grinding wheel has three components: Abrasive grains that do actual cutting. Bond which holds together the abrasive grains in the wheel while they cut and releases grains when they become dull, so as to provide new sharp grains. Structure which is the void or air space left between adjacent grains coated with bond, so…
Selecting right grinding wheel for a specific application, if properly understood, is not difficult. Some times, the first selection of the wheel may not turn out appropriate and modifications in specification may be necessary. Factors Affect Choice of Right Grinding Wheel There are 6 factors which affect choice of a grinding wheel specification. Material to…
Centerless Grinding is an outer diameter grinding process sometimes we call it OD Grinding. Centerless grinding is a process used to remove
Grinding Wheel in Industry A vitrico grinding wheels is the most common equipment in the metallurgy industry. Grinding Wheel cuts metals with different sizes, shapes, and efficiency. 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…
Precision grinding of the outer surface of any cylindrical piece is called OD grinding. OD grinding operations on cylindrical pieces, are done on two different types machines. Centre or centerless type, and by two different methods of applying the work pieces to the grinding wheel. The difference in two methods is based in the method…
The grinding wheels are safe operating tools, but also it must be remembered that they are fragile and breakable. Grinding is a safe operation under normal conditions. Severe stresses can be set up in the grinding wheel if, established, safe operating practices are not maintained. A thorough knowledge of the nature and characteristics of grinding…
Handling of Grinding Wheels All the abrasive wheels are breakable and some are very fragile. Great care shall be exercised in handling and storage to prevent damage which might cause a wheel to fly apart when speed up. Wheel shall be handled carefully to prevent dropping or bumping. Wheels shall not be rolled except in…
You can improve your grinding profitability by tracking and measuring following parameters. These parameters all work together and adjusting one or more parameters changes the result. Balancing important parameters allows you to improve grinding efficiency by making necessary changes. Let’s discuss with important main factors that influence grinding efficiency. 1) Machine and tools Rigidity, precision…
