According to OSHA grinding regulations, grinding machines must have safety guards. A guard must cover the machines spindle end, flange projections and nut and have secure mounting that keeps it in line with the grinding wheel.
Sep 04, 2013 ANSI B7.1 has been called the Bible for grinding wheel safety for good reason. It is the abrasive grinding wheel industry standard for the Safety Requirements for the Use, Care and Protection of Abrasive Wheels and most abrasive wheel safety-related questions can be found there.
Jun 02, 2017 Wheels should have an RPM rating that matches the RPM rating of the grinder motor. Use the correct type of wheel for the material you are grinding. Store wheels so that they are not subject to the environment or damage. Guarding is extremely important for safe grinder operation. Side guards should cover the spindle, nut, flange and wheel.
Apr 08, 1994 Machines that use abrasive wheels are powerful and most operate at high speeds. Some abrasive wheels operate at several thousand revolutions per minute. If a grinding wheel shatters while it is turning, the fragments from the wheel assembly including the flange, spindle end, and nut can travel at more than 300 miles per hour.
Ring test and visually inspect all grinding wheels before they are mounted. FEDOSHA 1910.215, CALOSHA 3580 Verify that the maximum RPM rating of each abrasive wheel meets or exceeds the grinder RPM. FEDOSHA 1910.215d1, CALOSHA 3583 Use approved lockouttagout means and procedures for all maintenance activities.
Sep 03, 2020 Safety while grinding work Most injuries reported during grinding work are cuts to fingers and eye injuries from flying objects such as metal parts or sparks.Grinding is the process of finishing the workpiece to remove sharp edges or maintain surface

Jan 21, 2015 How to ring test a grinding wheel. Grinding wheels must be inspected and ring-tested before they are mounted to ensure that they are free from cracks or other defects. Wheels should be tapped gently with a light, nonmetallic instrument. A stable and undamaged wheel will give a clear metallic tone or ring.
Oct 03, 2016 Bring work into contact with the grinding wheel slowly and smoothly, without bumping. Apply gradual pressure to allow the wheel to warm up evenly. Use only the pressure required to complete a job. Move the work back and forth across the face of the wheel. This movement prevents grooves from forming. Wheels are made only for grinding certain items.
OSHA specifies that work-rests must be kept adjusted to within 18 in of the wheel to prevent the workpiece from being jammed between the wheel and the rest, resulting in potential wheel breakage. In addition, the distance between the grinding wheel and the adjustable tongue-guard also known as a spark arrestor must never exceed in.
Mar 01, 2017 Remember to document any safety requirements set forth by OSHA as that is the best evidence that safety procedures are being followed. Grinder Safety Ring-Testing. OSHA requires that grinding wheels be ring tested before mounting them. This simple step prevents the inadvertent mounting of a cracked grinding wheel.
May 13, 2019 OSHA requires a maximum clearance of 14 between the grinding wheel and the tongue guard. If a wheel breakage should occur, maintaining the proper distance will help to contain the wheel fragments and reduce the probability of an injury. ... Torque Requirements for Grinding Wheels Mounted Between Flanges.

The maximum angular exposure of the grinding wheel periphery and sides for safety guards used on cutting machines and on surface grinding machines which employ the wheel periphery shall not exceed 150 degrees. This exposure shall begin at a point not less than 15 degrees below the horizontal plane of the wheel spindle.

Oct 03, 2016 Right-angle grinder - the grinding face of the wheel or disc is at an angle of between 5 and 15 degrees from the grinding surface. Vertical grinder - the grinding wheel face is in contact with the surface. Use racks or hooks to store portable grinders. Stand away from the wheel when starting grinders. Warn co-workers to do the same.
Mar 01, 2013 Torque Requirements for Grinding Wheels Mounted Between Flanges. Excessive tightening of grinding wheel mounts can cause damage to the machines grinding wheel mounting flanges. To prevent wheel breakage, learn the torque requirements for grinding wheels mounted between flanges. Read more
Grinding wheel safety operation regulations Dust masks or protective masks and glasses must be worn. Before work, check whether the grinding wheel is damaged, whether the safety protection device is intact, and whether the ventilation and dust removal device is effective.
It is based on the premise that grinding is a safe operation when a few basic rules are followed. These rules are based on material contained in the American National Standards Institute Safety Requirements B7.1 Use, Care amp Protection of Abrasive Wheels. Follow them.
Use the correct wheel for the machines size and speed, and the work to be performed. A cutting disc should not be used for grinding. The RPM rating of the discblade must be higher than that of the angle grinder. Adjust guards to deflect flying particles away from operator. Use an 180 guard between operator amp wheel.
Feb 01, 2019 ANSI B7.1 Safety Requirements for the Use, Care and Protection of Abrasive Wheels is the industry standard and the authority of knowledge for grinding wheels in North America. Compliance to this safety standard is critical to end user safety.
Apr 01, 2014 Improper flanging causes additional stresses to the abrasive wheel, and is a common cause of wheel breakage therefore, it is critical that the design and condition of flanges meet the requirements of Section 5 of ANSI B7.1-2000.
