• Run a new grinding wheel for about one minute before engaging the wheel into the work. • Wait for the wheel to reach maximum speed before using it as there may be unseen faults in the wheel. • Stand to one side of the wheel before starting the grinder.
7. Grinding • Use both hands to maintain hold of the grinder. • Allow grinder to reach full rpm before grinding. • Position yourself to avoid overbalancing. • When grinding avoid placing excessive pressure on abrasive wheels. • Do not grind objects on sides of grinding wheels.
Grinding in one direction is usually better for maintaining flatness than grinding in both directions. This procedure can be done dry for certain delicate materials, but water is usually added to keep the specimen surface cool and to carry away the grinding debris. For manual work, use a tuft of cotton soaked in a detergent solution. For
Allow grinding wheel to reach working speed before applying to work piece. Increase working loads gradually. Never abruptly. Use smooth fluid motions Be aware of flying sparks and particulate. Aim debris away from self and other people as well as flammable materials Turn grinder off when not in use
Keep work area clean and tidy. Use only in designated grinding area erect screens if necessary. Examine the power cord, extension lead, plugs, sockets and power outlet for damage. Ensure that the grinding disc, guard and attachments (including handle) are secure and correctly fitted. Inspect the grinding disc for damage. Do not use

reducing the gap between the wheels, grinding the work. Surface grinding produces flat, angular, or contoured surfaces by feeding work in a horizontal plane beneath a rotating grinding wheel. Work is most often magnetically attached to the table, and may be ground by either a traversing or rotating movement of the table.

Ensure that the grinding disc, guard and attachments (including handle) are secure and correctly fitted. Inspect the grinding disc for damage. Do not use
• Keep the floor and work area clean. Store flammable and combustible materials a safe distance (e.g., a minimum of 35 feet) away from the grinding operation. Sparks can ignite debris and flammable vapors. In some cases, a hot work permit may be required. See the EHS SOP, Hot Work Permit Operations for additional information.
• Prior to starting the grinder, ensure guards enclosing the outside of grinding wheel are in place. • Prior to adjusting the work rest or tang, unplug the power to the grinder from the wall receptacle. • If the grinder is hardwired into a box, Lock-out/Tag-out. • Be alert and cautious when a grinding
Bench Grinder Operating Procedures 1. Inspect & Adjust Grinder Ensure area around grinder is clean and well maintained. Side guard must cover the spindle, nut and flange and 75% of the abrasive wheel diameter*. Check the work rest gap must be no greater than 1/8 inch adjust if necessary*.
This procedure applies to wet sawing, grinding, and drilling/coring by Facilities operations Management (FM) personnel and contractors. 3.0 Responsibility 3.1 Facilities Management Environmental Resources Environmental Resources is responsible for working with staff to
When capabilities and the nature of the work. The utility grinding machine consists of a horizontally mounted motor with a grinding abrasive wheel attached to get price. Sample SAFE Work Procedure Templates: All Industries. Supervisors must ensure that safe work procedures are followed. Safe work procedures should be readily available to
§ On completion of the grinding procedure, clean down the Disc grinder and return it to its storage position. § The grinding wheel should be fully protected when the Disc grinder is on the work bench or when being stored. § Look for cracked or damaged casing, bare wires, loose connections, damage to
Standard Operating Procedures of Hand Tools Introduction To safely use each tool in Ideation Station, follow the standard operating procedures below. Every hand tool in Ideation Station is listed and described in this document. If you are unsure from a work piece, or smooth out the surface of a work
Operating Procedure 1. Inspection Before using the polisher/grinder inspect it and its surroundings for the following: C Make sure the electric power connections are made correctly and that the power cable is not damaged. C Make sure the polisher/grinder, including the wheel and the bowl, are clean. C Make sure the table and the floor around the table are clean and dry.
Dec 08, 2016· For example, when grinding with a 4” (101.6 mm) wide superabrasive wheel, the rest blade will generally work well at 30º. But with a wheel width of 6” (152.4 mm) or 8” (203.2 mm), that same angle may generate too much pressure toward the grinding wheel and cause chatter.
required. Generic safe work procedures are discouraged as they may tend to overlook specific circumstances such as location, weather, knowledge and experience required, time of day, other equipment involved, etc. Tickner and Associates Inc. is available to assist your firm in developing site-specific safe work procedures for the circumstances
Feb 22, 2016· The diameter of the central hole in the grinding disc (3) must fit the inner flange (10) without any play. Do not use any adapters or reducers. Use clamps or other practical way to secure and support the workpiece to a stable platform. Holing the work by hand or against your body is unstable and may lead to loss of control. Do not force tool.
