If a grinding wheel becomes cracked, it can fly apart, ejecting chunks of wheel like missiles. To reduce the safety hazards from wheel explosions,wheel guards (Figure L-34) are used on nearly every type of grinding machine. All grinding wheels are rated at a specific maximum rpm. Exceeding rated speeds can cause a wheel to fly apart.
2014-3-17OPERATIONAL SAFETY PROCEEDURES 1 Stand to the side of the wheels when starting up.. 2 Let the wheels gain maximum speed before starting to grind.. 3 Do not grind on the side of the wheel.. 4 Small objects must not be held by hand.. 5 Never leave the machine running unattended.. 6 Do not bend down near the machine whilst it is running..
Ensure that a machine will not operate when unattended by checking the dead-man (constant pressure) switch. Wear safety glasses or goggles, or a face shield (with safety glasses or goggles) to protect against flying particles. Gloves, aprons, metatarsal safety boots, and respiratory protection may be required, depending on the work.
2017-3-2327. Wear safety glasses, goggles, or a face shield when performing grinding operations, even though the machine is fitted with eye shields. True False 28. Never force a grinder wheel onto the machine or the size of the mounting hole. True False 29 It is OK to stand directly in front of a grinding wheel whenever a grinder is started.
Grinding machines, like broaching machines, operate over a range of speeds depending on the type of machine being used.These range from approximately 1250 to 2000m min −1, although in high-speed grinding speeds of up to 5400m/min are achievable (Schey, 1987).The two most common grinding applications are cylindrical grinding and surface grinding.
The minimum wall thicknesses for safety guards are specified in ISO Standard 16089 Machine tools - Safety - Stationary grinding machines. For example, there is a directly proportionate link between the requirements concerning primary protective covers for gear grinding machines and those for the full enclosures located further away.
