For larger grinders, grinding wheels are laid flat on a vibration-table with sand evenly spread over the wheel. If the wheel is cracked, the sand moves away from the crack. To prevent cracking a wheel during the mounting procedure, employees must be very carefully trained in those procedures.

These steps are outlined in OSHA standard 1910.215 and most grinding wheel manufacturers' websites. While you're there, also download ANSI standard B7.1, Safety Requirements for the Use, Care & Protection of Abrasive Wheels, a document that Norton Saint-Gobain refers to as the bible of grinding wheel safety.

do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control. - Do not use a damaged accessory. Before each use inspect the accessories such as abrasive wheels for chips and cracks, …

An abrasive wheel may be damaged in shipment or storage or the wheel may be subjected to improper, excessive stresses during mounting. Wheels which have been damaged or are under excessive stress are likely to fracture within the first minute of rotation at operating speed. While this procedure is most important at the time when an abrasive ...

A "mount up" arrow on the wheel face should point upward when attaching the flange. (Norton)

Push the grinding wheel against the blotter. Slide another blotter and then a flange against the grinding wheel. Thread the nut onto the spindle. Tighten the nut with an adjustable wrench. Only tighten the nut to the point the grinding wheel holds secure on the bench grinder. Step 6 Remove the lockout tag from the grinder switch set.

9. Abrasive Wheel. The function of an abrasive wheel is to get rid of the matter from the surface of the work piece. It is covered with abrasives in order to achieve high precision. 10. Coolant. The function of the coolant is to reduce the temperature of the work region so that heat cannot be dissolute into the work piece and grinding wheel.

By the end of the course delegates will be able to: -. Identify different types of abrasive wheels. Understand the BS marking system. Identify the need for the rpm to be marked on the machine and the cutting/grinding discs. Learn correct mounting procedures. Identify different types of abrasive wheel machines excluding bench mounted.

Course Details. This course is designed to provide the necessary knowledge and skills required to demonstrate the selection and safe fitting of abrasive wheels in accordance with manufacturer's guidance and current legislation. This attracts a CITB Short Course Duration Grant at …

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.

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.

Mounting of abrasive wheels. The danger of an abrasive wheel bursting is considerably increased if it is not properly mounted; many accidents could be prevented if the people mounting the wheels were instructed in the hazards arising from incorrect mounting and in the correct method of assembly.

Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece, they act as tiny cutting tools, each particle cutting a tiny chip from the workpiece.

Proper cutting procedures must be followed; abrasive cut-off wheels will crack and become flying projectiles when used improperly. Lab Procedure - Sectioning 1. Place the sample on the slotted Table so that it is at the center of the swing of the head. 2.

When it comes to grinding and polishing safety, there are some factors that should be considered before the operator even starts to touch a workpiece. All operators should be aware of these practices. Some of these considerations include ergonomics, safety gear, correct speed (RPM), spark control, use of guards, accurate mounting of abrasives, as well …

Ensure mounting pilot (s) is rounded with length about 2/3 width of the wheel. Extend the threaded section well inside the loose flange. Tighten grinding wheels just enough to prevent them from slipping. Over tightening the spindle nuts or clamping screws can damage the wheel and grinder parts.

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.
