The Do s and Don ts for Handling Storage and Inspection

Handle all grinding wheels with care. Remember there is no such thing as an unbreakable grinding wheel. Be safe and follow the attached Do s and Don ts for handling storage and inspection of grinding wheels.Do s Do check all shipments of grinding wheels for possible damage in transit. Do report any damaged containers or pallets. Grinding wheels are designed to operate at high speeds and can throw fragments at over 300 MPH if they shatter during use. For safety the wheel should be regularly inspected for cracks however visual inspection cannot be relied upon to reveal hairline fractures. A wheel can be tested by lightly striking it with a metal object.

Check grinding wheels for cracks (Ring Test Figure 5-11) before mounting. Never operate grinding wheels at speeds in excess of the recommended speed. Never adjust the workpiece or work mounting devices when the machine is operating Do not exceed recommended depth of cut for the grinding wheel or machine. Remove workpiece from grinding wheel 5. visual inspection of power cord/conduit (frays cracks etc.) grinding wheel 1. grinding wheel in good working condition (see note) 2. contact surfaces are flat and free of foreign matter 3. blotters and flanges are of correct size work rests 1. rigidly constructed stable adjustable 2. rest is adjusted to within 1/8" of wheel safety guard 1.

Effective Methods for Checking Grinding Quality Gear

An effective method for grinding process control and quality inspection is the Barkhausen Noise method. This method was first discovered in 1919 and implemented to grinding quality control during the 1980s. It is sensitive to residual stresses and microstructure which are directly involved with the grinding quality of the part. The acoustic emission generated during the grinding process is analyzed to determine its sensitivity to process efficiency and the condition of the grinding wheel. Acoustic emission from surface grinding is used to measure wear-related loading of the grinding wheel and sparkout (or loss of contact) between the wheel and the work surface.

In addition to looking at essential training needs the guide also focuses on details such as wheel characteristics safety in grinding machine operations wheel mounting procedures and issues guards extra considerations for portable or hand-held grinders and protective equipment requirements. How your wheel/hub bearings can make a grinding noise Designed to serve as a buffer between the axle and wheel wheel or hub bearings eliminate friction between these parts. If your wheel bearings are worn it can cause a grinding noise while turning the vehicle.

Oregon Occupational Safety and Health Abrasive 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. Grinding wheels are designed to operate at high speeds and can throw fragments at over 300 MPH if they shatter during use. For safety the wheel should be regularly inspected for cracks however visual inspection cannot be relied upon to reveal hairline fractures. A wheel can be tested by lightly striking it with a metal object.
