To minimise the risk of bursting, abrasive wheels should always. be run within the specified maximum rotation speed. If they are large enough, this will be marked on the wheel (a. requirement of regulation 23) Smaller wheels should have a notice fixed in the workroom, giving the individual or class maximum permissible rotation speed.

This legislation, referred to as concerning the use of abrasive wheels in the workplace 2007 to 2016, outlines the duties of the employer including the requirement to avoid using abrasive wheels where possible, to carry out risk assessments and to reduce the risk of abrasive wheel injuries to employees by implementing appropriate controls.

Grinding Wheel Care. Recondition frequently to keep the grinding wheel in good condition. The process for cleaning the periphery of the wheel is called dressing. The dressing process involves breaking away any dull abrasive grains to create a smooth wheel surface. The wheel dresser is used for dressing grinding wheels on bench and pedestal ...

Abrasive wheels training is a legal requirement under the Provision and Use of Work Equipment Regulations 1998 (PUWER 98). It is imperative for those operating abrasive and grinding wheel equipment in the workplace, and provides learners with guidance on precautions for the prevention of accidents in the use of abrasive wheels, particularly ...

Proper mounting procedures for grinding wheels

Portable Abrasive Wheel Tools. One of the most common tools found in any shop, the portable grinder is incredibly useful for grinding and finishing material of all shapes and sizes. The hazards associated with portable grinders are similar to those of pedestal or bench grinders. The rotating abrasive stone can cause severe abrasions and cuts.

Be sure edge of grinding wheel clears side of work after each pass 20. Take as many passes (.001 in.) as needed 21. Set wheelhead for .0005 in. depth for final pass to improve surface finish 82-38. Procedure to Grind a Vertical Surface 1. Mount proper grinding wheel; true, dress and balance 2. Dress side of wheel to give it slight clearance 3.

• Follow the manufacturer's instructions for mounting grinding wheels. • Keep face of the wheel evenly dressed. • Ensure that the wheel guard covers at least one half of the grinding wheel. • File off any burrs on the surface of work that is placed on the magnetic chuck.

9. Abrasive Wheel. The function of an abrasive wheel is to get rid of the matter from the surface of the work piece. It is covered with abrasives in order to achieve high precision. 10. Coolant. The function of the coolant is to reduce the temperature of the work region so that heat cannot be dissolute into the work piece and grinding wheel.

These steps are outlined in OSHA standard 1910.215 and most grinding wheel manufacturers' websites. While you're there, also download ANSI standard B7.1, Safety Requirements for the Use, Care & Protection of Abrasive Wheels, a document that Norton Saint-Gobain refers to as the bible of grinding wheel safety.

• Ensure that the abrasive product is suitable for its intended use. Examine all abrasive products for damage or defects before mounting. • Follow the correct procedures for handling and storage of abrasive products. Be aware of the hazards likely during the use of abrasive products and observe the recommended precautions to be taken:

Proper steps in mounting a grinding wheel are as follows: Handle and store grinding wheels in a careful manner. Handle and store all grinding wheels as if they were made of glass! Select the proper grinding wheel and machine for the job. Lock out and tag all machines before working on them.

Proper mounting of cut-off wheels and grinding discs is essential. Do not force a wheel onto a machine or alter the size of the arbor hole. Do not use a wheel which fits the arbor too loosely. Do not bump a grinding disc when starting to grind. Start the cut gently. Depressed-center grinding discs (Type 27) are best used at an angle of 15°.

Grinding, or abrasive machining, is the process of removing metal in the form of minute chips by the action of irregularly shaped abrasive particles. These particles may be in bonded wheels, coated belts, or simply loose. Grinding wheels are composed of thousands of small abrasive grains held together by a bonding material.
