Is the work rest used and kept adjusted to within 1/8-inch (0.3175cm) of the wheel? 215(b)(9) Is the adjustable tongue guard on the top side of the grinder used and kept to within 1/4-inch (0.6350cm) of the wheel? 215(d)(1) Is the maximum RPM rating of each abrasive wheel compatible with the RPM rating of the grinder motor? 215(d)(1)
An agreed safe procedure has been established and communicated for the agreed task. Grinding work is necessary. Could a different tool be used with less risk? The correct size grinder is selected for the job. The correct flange and locking nut is in place for the type of disc being used.
• 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.
Cutting and Grinding Safety. Cutting and grinding is performed on many jobsites. The following are a list of safety precautions that must be followed to prevent injury or property damage. Stay alert and watch what you are doing. Do not use tool while tired or under the influence of drugs, alcohol or medication.
Dec 08, 2016· A downside of centerless grinding is you can't have as many multiple axes operating on the workpieces. However, there are many parts where the process addresses the limitations of machining in terms of dimensions, materials, and surface finishes. That's why we like to say that where machining ends, the centerless grinding process begins.
Basics of Grinding Fundamental Manufacturing Processes Video Series Study Guide - 3 - different internal contours can be produced within a workpiece using I.D. grinding. In centerless grinding, the workpiece rotates between a grinding wheel and a regulating drive wheel. The work is supported from below by a fixed work-rest blade.
grinding operation can loosen chips or particles that can fly into the eye. On rare occasions, excessive speed can make an abrasive wheel disintegrate, which could send pieces of metal flying through the work area—and into your eyes. Yet another hazard is inhaling the dust and fumes generated during grinding, which can lead to respiratory ...
For dry grinding the work input should normally be multiplied by 1.30. However, ball coating and packing can increase the work input in dry grinding. The accompanying procedure and table can be used to shorten the calculations required with the new formula.
A grinding wheel is an expendable wheel used for various grinding and abrasive machining operations. It is generally made from a matrix of coarse abrasive particles pressed and bonded together to form a solid, circular shape, various profiles and cross sections …

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
18. Stabilize work pieces before grinding. 19. To avoid any accidents, once a wheel starts functioning, keeping a safety distance between the work piece and the wheel is obligatory. 20. DONT leave the operating grinder unattended. 21. Only firmed work pieces are allowed to put on the machine during grinding…
For larger grinders, grinding wheels are laid flat on a vibration-table with sand evenly spread over the wheel. If the wheel is cracked, the sand moves away from the crack. To prevent cracking a wheel during the mounting procedure, employees must be very carefully trained in those procedures.
Grinding machines remove material from the work piece by abrasion, which can generate substantial amounts of heat. To cool the work piece so that it does not overheat and go outside its tolerance, grinding machines incorporate a coolant. The coolant also benefits the machinist as the heat generated may cause burns.
Jun 03, 2013· Besides, high-quality grinding discs as well as flap discs work with right-angle grinders as a system. An old jalopy (that is, a low-quality grinder) with fancy tires (high-quality grinding disc) may drive a little better, but it's still not the smoothest ride. 2. Be safe. Using the right tool for …
