Grinding wheels with diamond or CBN grains are called superabrasives. The rate of wear in this process is usually very predictable for a given application, and is necessary for good performance. A general guide to specification marking can be seen in the table here:. In other projects Wikimedia Commons. Other, non-safety related information.

Dressing the wheel refers to removing the current layer of abrasive, so that a fresh and sharp surface is exposed to the work surface.
Other, non-safety related information. From Wikipedia, the free encyclopedia. A grinding tool for non-metallic materials such as stone, porcelain and the like, and more particularly to a grinding tool using a diamond alloy as a grinding body comprising a substrate and a plurality of grinding bodies, And the substrate is preferably made of an adhesive material having a certain toughness, and the grinding body is preferably made of a diamond alloy material, and the substrate is preferably made of a diamond alloy material, The utility model has the characteristics of high grinding performance, simple manufacture and low cost, high grinding quality and can be applied to large-scale grinding.
Grinding wheels are consumablesalthough the life span can vary widely depending on the use case, from less than a day to many years.
The size of the grinding wheel is marked as dimensions in mm. They are often used in the construction industry for cutting reinforcement bars rebarprotruding bolts or anything that needs quick removal or trimming. Articles needing additional references from January All articles needing additional references. This can be used to advantage on many tools such as chisels.
They are used on the periphery only and therefore produce a slightly concave surface hollow ground on the part. Various profiles and cross sections are available depending on the intended usage for the wheel. Straight Wheels are generally used for cylindrical, centreless, and surface grinding operations.
Louise prefers not to specialise in one particular area, griinding has written about everything from asbestos and COSHH, through nomencltaure food safety, safeguarding issues and business skills.

For the Overkill album, see The Grinding Wheel. Views Read Edit View history. This article needs additional citations for verification. They are used only in vertical or griding spindle grinders. Most handymen would recognise an angle grinder and the discs they use. Abrasive Wheel Markings All abrasive wheels are marked with: They are used for grinding extremely hard materials such as carbide cutting tipsgemstones or concrete.
Grinding and lapping Metalworking tools. A grinding wheel, also known as an abrasive wheel, is a wheel made of abrasive particles bound together by various substances, such as rubber, shellac or silicate.
The wheels are generally made from a composite material consisting of coarse-particle aggregate pressed and bonded together by a cementing matrix called the bond in grinding wheel terminology to form a solid, circular shape.
Many of the main types of ceramic mounted points, grindijg mounted points, diamond mounted points, emery cloth and so on. Made from natural rubber or synthetic rubber.
Understanding the Marking System for Abrasive Wheels
The arrow should point downwards when the wheel is mounted. This page was last edited on 9 Novemberat The saw pictured to the right is a slitting nomenclatuure and is designed for slicing hard materials, typically gemstones. Grinding wheels with diamond or CBN grains are called superabrasives.
To use the grinding wheel it must first be clamped to the grinding machine. The specification of the grinding wheel is marked as a series of letters and numbers. Diamond mounted points are tiny diamond rasps for use grindinng a jig grinder doing profiling work in hard material.
For smaller grinding wheels below 80mm in diameterthe maximum operating speed is provided on a separate notice which must be stored alongside the wheel.
All operators should have a strong awareness of the hazards associated with grinding wheels, as well as how to correctly store and handle them, inspect them for damage and nomenclaturs appropriate control measures.
One of the first control measures to adhere to is ensuring that you understand the marking system for grinding wheels. Ultra-fine grain sizes are for precision finish work. Post Author Louise Petty.
