Abrasive wheels used on bench and pedestal grinding machines must be equipped with safety guards. The safety guard encloses most of the wheel — covering the flange, spindle end, and nut projection — while allowing maximum exposure of the wheel periphery.
What is the function of wheel guard?
Wheel guards prevent mud, dirt and other debris from causing damage.
What is the function of a wheel guard on a bench grinder?
The wheel guards serve to intercept the fragments of an exploding wheel, keeping them from killing people or damaging surroundings. This is why running a grinder without the guards is prohibited.
Why are abrasive wheels used?
They are used for surface modification or preparations (external or internal) by periphery grinding, abrasive cut-off and face grinding standard designs; they (disc) can also be used for cutting materials. Some are used for polishing, deburring, sanding and finishing.
What is a Type 1 grinding wheel?
Type 1 Wheel – A thick disc shaped wheel intended for grinding on its periphery as in bench grinders or straight grinders. … Type 29 Wheel – A saucer/center depressed shaped wheel intended for grinding on the face of the wheel used with angle grinders fitted with the appropriate guard.
What is the best method for inspecting abrasive wheels for cracks?
What is the best method for inspecting abrasive wheels for cracks? When in doubt, throw it out. Before mounting, inspect closely for damage and perform a sound or ring-test to ensure that the wheel is free from cracks/defects.
What is grinding wheel specification?
Diamond/CBN grinding wheels (super abrasive wheels) can be applied to various specifications by combining “abrasive grain (abrasive grain type)”, “grain size (abrasive grain size)”, “bond strength”, “degree of concentration (grain concentration in bond)”, and “bond type (bonding material)”.
What is the process of grinding?
Grinding is an abrasive machining process that uses a grinding wheel or grinder as the cutting tool. Grinding is a subset of cutting, as grinding is a true metal-cutting process. … Grinding is used to finish workpieces that must show high surface quality and high accuracy of shape and dimension.
