This is the content required for an introduction to our bench grinder - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)
Let's begin! First off, make sure you have read the machine's manual, if available (should be linked from its InfoBox).
Safety
Dangers
- generation of hot sparks that are expelled in varying directions
- sparks can fly far and deposit themselves as fine dust
- the workpiece heats up and stays hot for a while
- has no prevention of turning on after loss & restoration of power (keine Anlaufsicherung)
- metal dust can be a health hazard when inhaled
- aluminum can clog an abrasive wheel and cause it to overheat until it breaks
- the workpiece can get caught on the wheel and get jerked from your hand
Precautions
- wear goggles to protect your eyes
- wear a proper dust mask when working with the bench grinder
- wear suitable gloves to prevent burns from sparks or the workpiece
- do not attempt to vacuum up sparks! The dust collection bag could catch fire
- do not attempt to grind aluminum
- let the wheels get to full speed before you start grinding
- use the tool rests whenever possible
- make use of the grinder's plastic spark guards, if available
