To ensure that grinding wheels are safely used in your workplace, know the hazards and how to control them. Solution. Abrasive wheels used on bench and pedestal grinding machines must be equipped with safety guards. The safety guard encloses most of the wheel — .
The basic machine shall have a robust and vibration free construction and high power rating to ensure accurate grinding of jobs. Machine should have push buttons controlling the different functions of the machine. Devices should be protected against shortcircuiting with .
Dress regulating wheel at the same angle as dressing grinding wheel (in order to prevent bent caused by uneven grinding force). Dress wheel to ensure that it has slight gradient upward to exit side. Spirals: Incorrect wheel dressing: Dress wheel so it stops grinding 1/2 from exit edge. Round off both edges of wheel. Guides improperly adjusted
Protective guards Grinding wheels must be guarded by appropriate protective guards on grinding machines. These guards must be capable catching broken wheel fragments effectively. Only that part of the wheel required for grinding may be left unprotected. Certain operations may require even the entire wor¬king area to be guarded.
Cylindrical grinders. The maximum angular exposure of the grinding wheel periphery and sides for safety guards used on cylindrical grinding machines shall not exceed 180 deg. This exposure shall begin at a point not more than 65 deg. above the horizontal plane of the wheel spindle. (See Figures O10 and O11 and subparagraph (9) of this paragraph.)

Dec 23, 2018· The grinding machine provides high accuracy and fine surface finish with minimum tolerances. The machining process is done by the abrasive action of the grinding wheel; the abrasives are embedded over the periphery of the rotating wheel. In Grinding machine grinding wheel is work as a cutting tool and responsible for all machining processes.
Grinder Machines Process Description. The grinding machine consists of a power driven grinding wheel spinning at the required speed (which is determined by the wheel''s diameter and manufacturer''s rating, usually by a formula) and a bed with a fixture to guide and hold the workpiece.

The maximum angular exposure of the grinding wheel periphery and sides for safety guards used on cylindrical grinding machines shall not exceed 180 deg. This exposure shall begin at a point no more than 65 deg. above the horizontal plane of the wheel spindle. Surface grinders and cuttingoff machines
Do not exceed recommended depth of cut for the grinding wheel or machine. Remove workpiece from grinding wheel before turning machine off. Use proper wheel guards on all grinding machines. On bench grinders, adjust tool rest 1/16 to 1/8 inch from the wheel. 51
Abrasive grains are held together in a grinding wheel by a bonding material. The bonding material does not cut during grinding operation. Its main function is to hold the grains together with varying degrees of strength. Standard grinding wheel bonds are vitrified, resinoid, silicate, shellac, rubber and metal.
5. Move the grinding wheel down using the vertical table handwheel until it barely makes contact with the dresser. 6. Turn the machine off after making contact with the dresser. 7. Turn the machine on again. While the wheel is spinning, lower the grinding wheel down in the Z direction until it makes a small plume of dust. 8.
On fixed internal grinding machines, however, arrangements can be made so that a guard may be placed in position automatically when the wheel in motion is withdrawn from the work (Figures 10 and 11). Figure 10 A springloaded telpic guard for use on an internal grinding machine.
Floor and BenchGrinding Machines; Are all floor and benchmounted abrasive wheels equipped with safety guards? [29 CFR (a)(1) and (a)] Does the safety guard cover the spindle end, nut, and flange projections? [29 CFR (a)(2)] Is the maximum angular exposure of the grinding wheel and sides 90º or less?
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. True False 30. If the grinding wheel becomes loaded it is not necessary to dress it. True False Pedestal Grinder Study Guide Advanced Photon Source
