the improper mounting of a grinding wheel is a major cause of grinding wheel breakage. Proper steps in mounting a grinding wheel are as follows:
handle and store grinding wheels in a careful manner. Handle and store all grinding wheels as if they were made of glass!
select the proper grinding wheel and machine for the job.
Lock out and tag all machines before
working
on them. Disconnect portable machines from their power source before changing the grinding wheel. Visually inspect all grinding wheels. Also, the use of “ring testing” or “vibration testing” is required for many grinding wheels.
Grinding wheels can be extremely dangerous. If you over-rev the wheel, and it has microscopic defects or cracks, it may shatter, sending shrapnel everywhere and possibly injuring you or a co-worker. Here’s what you need to know about the proper care and maintenance of your grinding wheels. Despite its long history, its extreme precision and its ability to machine even the hardest of metals to a glasslike finish, grinding remains a bit of a black art. With a host of variables that include grit size, bond and the abrasive itself, it can be challenging to find the optimum wheel for a given grinding application, let alone use and care for it properly.
The training shall include suitable and sufficient instruction in the following matters in relation to each class or type of abrasive wheel in respect of which it is proposed to appoint the person being trained: proper methods relating to the mounting of abrasive wheels; hazards arising from the use of abrasive wheels and precautions which should be observed; methods of marking abrasive wheels as to type and speed; methods of storing, handling and transporting abrasive wheels; methods of inspecting and testing abrasive wheels to check for damage; the functions of all components used with abrasive wheels, including flanges, washers, bushes and nuts used in mounting, and knowledge of the correct and incorrect methods of assembling all components and of correct balancing of abrasive wheels;.
Since the causes of many grinding wheel breakages can be traced back to improper storage and handling, this section focuses on how to handle and store grinding wheels. Included in this section is information related to the shelf life of a grinding wheel.
Safety in the use of abrasive wheels
An employer must ensure that an abrasive wheel is suitable for the work for which it is used, having regard to the risk of personal injury to any person, and any person using abrasive wheels has undergone an abrasive wheels training course.
Statistics show most accidents involving abrasive wheels occur because of an unsafe system of work or operator error. There are obvious dangers of wheel breakage or contact with a running wheel but other, less obvious health risks, such as vibration, noise and dust. Work with abrasive wheels must comply with the safety, health and welfare at work (general application) (amendment) regulations 2016 (s.
S. I. No. 30 of 1982. Safety in industry (abrasive wheels) regulations, 1982. I, liam kavanagh, minister for labour, in exercise of the powers conferred on me by sections 6 and 71 of the factories act, 1955 (no. 10 of 1955), and the labour (transfer of departmental administration and ministerial functions) order, 1966 ( s. I. No. 164 of 1966 ), after consultation with the minister for health, and after compliance with the third schedule to that act, hereby make as special regulations the following regulations: 1. These regulations may be cited as the safety in industry (abrasive wheels) regulations, 1982, and shall come into operation on the 1st day of june, 1982.
