Safety with Grinding
⚫ Always use goggles or face shield while working on a grinder.
• Check the various parts and controls before the grinder is set in motion.
• Ensure that the wheel is flat and is free from depressions and grooves.
• Use only correct and sound wheels for the work.
• Ensure that tool rest in pedestal grinders is about 3 mm from the face of the wheel. If the clearance is more it may cause the job to jam the wheel and break it.
• Use the entire face of the wheel and not any particular portion to ensure uniform wear of the wheel.
• Use only the face of the wheel and not the side of the wheel unless specified.
• The wheel should be run at specified speed only.
⚫ Check frequently the balance of the wheel.
• Use proper holding devices or clamps while grinding small pieces.
⚫ Check the holding power of chuck before starting the machine in the case of surface grinders.
