Nature of the grinding operation: Finish required, accuracy and amount of metal to be removed must be considered when selecting a wheel. Fine and accurate finishes are best obtained with small grain size and grinding wheels with resinoid, rubber or shellac bonds.
The first abrasive wheel used might be a coarse grit, followed by 60 grit, then 80 grit and finally a 150 grit to slowly achieve the desired finish. But Rex-Cut wheels feature a non-woven cotton fiber that's denser than the non-woven nylon found in other abrasive wheels.
Grinding wheels are a great product for removing a lot of material quickly. They don't typically leave as smooth of a finish as other abrasive products, but they get the job done fast. If the application does not require a specific finish, this type of product may be best suited for the application.
Hilti grinding wheels are now available in three performance levels to ensure you have the right grinding wheel for your job. Our grinding wheels deliver improved productivity and safety along with a superior finish across a wide variety of materials and applications.

Available to fit many sizes and specification of machines with speed, quality and finish in mind. Review our selection include ID and bearing wheels, cylinder wheels, and other shapes.
Coated with an abrasive such as aluminum oxide (also known as corundum), ceramic aluminum oxide, or silicone carbide, they have a designated grit number that corresponds with their level of material removal and final finish. Surface grinding wheels may be extra coarse, coarse, medium, or fine.
Grinding wheels usually will be between 24 and 100 grit. Honing stones and jointing stones and other polishing abrasives will be 150 grit and higher. Use a coarse grit for fast, aggressive stock removal and finer grits for less stock removal but better surface finish. Grinding wheel hardness
Even fine finishing in profile grinding of gears can be done with conventional CNC gear-grinding machines; the only requirement is the use of a twin wheel. Even though elastic-bonded abrasives have been around for almost 100 years, such abrasives are not technologically stagnant.
The grinding wheel is a cutting tool. It's an abrasive cutting tool. In a grinding wheel, the abrasive performs the same function as the teeth in a saw. But unlike a saw, which has teeth only on its edge, the grinding wheel has abrasive grains distributed throughout the wheel.
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles ( grinding wheel ) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
Bench & Pedestal Grinding Wheels 372 items returned Refine Results List New Table ... Use smaller grits/finer grades where the final finish is important. Bench and pedestal grinding wheels are used for sharpening, shaping and deburring parts and tools. Bench grinding wheels are generally used on stone and metal materials.
Basics of Grinding Fundamental Manufacturing Processes Video Series Study Guide - 1 - Training Objectives ... worn machines yield a poor quality finish • wheel condition - clogged wheels cannot produce a good finish • lubricant cleanliness - coolant filtration removes waste that could damage workpiece surface.
A grinding wheel is a wheel composed of an abrasive compound and used for various grinding (abrasive cutting) and abrasive machining operations. Such wheels are used in grinding machines.. 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 …
The finish of a ground plastic is extremely dependent on the following factors: Wheel Grit; Wheel grit is the most critical factor in obtaining your desired surface finish. A grinding wheel with a rougher grit will remove more material per pass, but the result is a rougher surface finish.

vAs a rule, grinding wheels are used for rougher finishes that won't be painted, while flap discs grind and finish at once and produce relatively fine finishes. Resin-fiber discs can be used for a short lifespan to grind quickly with a relatively fine finish.
