On may 16 2019 how to safely mount grinding wheels used in sets we receive calls from our customers asking us if they can mount several wheels onto a single arbor in sets. Some of the grinding applications where it is common to use multiple wheels on a single spindle are centerless, crank and cam (bearing) grinding. What are the rules for mounting several wheels onto a spindle? what may happen if the correct procedures are not followed? we have been asked, “in applications with multiple wheels mounted on a single spindle without spacers, can we mix and match grinding wheels from different sets, different abrasive manufactures, different batches, etc.
Safety in the use of abrasive wheels
Guidance subsequent to the repeal of the abrasive wheels regulations 1970 (encompassing relevant puwer 1998 issues and any conflicts with draft european standards). 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.
This training course is a legal requirement for all those who are involved in the selection, storage, mounting, dressing and use of wheels in accordance with the requirements of abrasive wheels safety in industry regulations.
