Description
A pedestal grinder is a type of grinding machine used to drive abrasive wheels. This type of grinder is mounted on a pedestal, which may be bolted to the floor or may sit on rubber feet.
Here is an example of a grinder being used.
Documentation
Terminology
- Wheel Guard - The shroud around the wheel.
- Spark Guard - The adjustable metal slider located near the top of the wheel guard.
- Tool Rest - An adjustable piece of metal that serves several purposes. The rest helps prevents the workpiece from getting sucked into the wheel and also can be used to support the work.
Training
Operation
There is a grinding wheel captivated on both sides of the motor. The wheel is made up of abrasive material. As you press material up against the wheel small amounts of material get removed and begin to cut away the metal surface. The wheels spins at 3600 RPM so remember to always work on the lower portion of the wheel and never hold any parts so the edges can catch on the wheel. Never wear gloves while using rotating equipment.
Demonstration
You will need to demonstration how to safely grind a piece of scrap steel.
General Procedure
- Ensure that the pedestal grinder is stable
- Ensure that all the guards are in place before turning on
- Check to see if the tool rest is within 1/16" of the grind wheel. If you are unsure if it is within 1/16" of the wheel, adjust it as close to the wheel as you can.
- Make sure that the wheel turns freely before using
- Turning on the wheel, stand to the side of the machine and wait for it to come to full speed
- Bring work into contact with the grinding wheel slowly and smoothly, without bumping
- When grinding move back and forth across the face of the wheel. This prevents even wear on the wheel and prevents grooves from forming in your work piece
- Once done using, turn off the grinder and wait for it to come to a complete stop
Certification
Troubleshooting
Maintenance
General maintenance
The gaps between the wheel and grinding fixture rests should be no more than a 1/16" inch. As the wheel wears the technician will need to adjust the rests.
