8in Wheel Bench Grinder

Never grind aluminum or other non-ferrous materials on a grinding wheel.

What safety procedures should you follow when using bench and pedestal grinders?

• Fasten pedestal and bench grinders securely.
• Ensure all the guards are in place and secure before using a grinder.
• Adjust tool rests to within 1/8 in. (3 mm) of wheels. Never adjust rests while wheels are moving. Work rest height should be on the horizontal centerline of the machine spindle.
• Maintain 1/4 in. (6 mm) wheel exposure with a tongue guard or a movable guard.
• Check that wheels have blotters on each side.
• Check the wheel fits properly to the spindle when mounting. If it is loose, get another wheel.
• Stand to one side of the grinder until the wheel reaches operating speed.
• Bring work into contact with the grinding wheel slowly and smoothly, without bumping.
• Apply gradual pressure to allow the wheel to warm up evenly. Use only the pressure required to complete a job.
• Move the work back and forth across the face of the wheel. This movement prevents grooves from forming.
• Wheels are made only for grinding certain items. Do not grind rough forgings on a small precision grinding wheel.
• Dress wheels regularly. Do frequent, light dressings rather than one heavy dressing.
• Support dressing tools so you can apply leverage without undue effort. With revolving cutter dressing tools, use the lugs as anchors.
• Replace worn wheels if you cannot dress it.
• Ensure the grinder speed does not exceed the operating speed marked on the wheel.
• Visually inspect wheels for possible damage before mounting.
• Wear proper personal protective equipment:
  • eye, ear and face protection,
  • metatarsal safety boots, where required,
  • respiratory protection may be required, depending on the work.
• Wear gloves only where necessary.

What should you avoid when using bench and pedestal grinders?

• Do not use a wheel that has been dropped.
• Do not use a wheel that does not fit properly to the spindle.
• Do not use excessive force to tighten the nut of the wheel. The force can crack the wheel.
• Do not grind wood, plastics, and non-iron metals on ordinary wheels.
• Do not leave grinding wheels standing in liquids. The liquid can cause balance problems.
• Do not grind on the side of a regular wheel.
