It will allow the wheel to cut faster, cooler and with a better surface finish. 3. Hand-Held (Portable) Grinder Safety 3.1. Right Wheel and Right Dimensions . The use of the right dimension of the grinding wheel plays a vital role in ensuring safety and achieving higher efficiency. It also helps in achieving the maximum allowed rotation speed ...

Higher wheel speeds, such as employed in high speed grinding, are predicated on the use of special grinding wheels and on machine design, including reinforced wheel guards, adapted to such operations. The infeed rates listed in Table 1-7.1 refer to the penetration of the grinding wheel into the work material.

Grinding abrasives require the right guidance about how to store, test, and use them; otherwise, a routine grinding application can turn into a safety nightmare. Sparks, airborne debris, and a disengaged, detached wheel can all present safety hazards to you and those around you. Improper use also can cause the grinding wheel to break, which can ...

Ensure that the accessories used always fulfill the following minimum requirements. Respect the maximum grinding-disc diameter. 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 ...

Grinder safety gauges can be used during the installation, maintenance, and inspection of bench/pedestal grinders to ensure work-rests and tongue-guards comply with OSHA's 1910.215 regulation and ANSI standards. To do so, wait until the wheel has completely stopped and the grinder is properly locked out before using a grinder safety gauge.
