New Bench Grinder
« on: December 01, 2012, 08:15:37 AM »
We now have a bench grinder :)  located in the metal working area.


It is brand new so let's take care of it.  Here are a few rules and tips for safe effective grinding.


Safety:
  • Wear safety goggles
  • Keep spark shields in place.
  • Check for loose fittings before use.
  • Make sure both wheels are clear before use.
  • Hold small pieces with a vice grips.
  • Clamp the grinder to the bench to prevent it from walking away while in use.
  • It spins quietly.  Make sure to turn it off after use.
  • Do not eat it - it may cause choking.
Grinding:
  • The grinder is ONLY FOR HARD METALS.  Do not use for Copper, Aluminum, Brass, Plastic, etc.  These will clog the wheels.
  • Avoid burning your work.  Grinding creates a lot of localized heat which will soften the metal.  If your piece turns red you have burned it.
  • Use light pressure to keep your piece cool.
  • Dip your piece in water frequently to keep it cool.  It is normal for the piece to boil the water as it is dipped in.  A small sizzle is good.  A big boil means you waited too long.
  • Keep your piece moving across the face of the wheel.  Grinding removes material from both your piece and the wheel.  If you grind in one place the wheel will become deformed and make it harder to grind a straight edge.
  • There are two wheels;  A course one. and a fine one.  Use the course wheel for rough cutting and the fine one for finish work.

Add to safety: Wear breathing protection - you are inhaling bits of metal and grinding wheel - not good.

When I installed the bench grinder I wrote on the top of it, "No aluminum, copper, brass" and made that the first grinding rule.  This means do not grind these things on the grinder because it will clog up the grinding wheel.  It is clear someone has been grinding aluminum on it because there are nice shiny globs all over the wheels now.  They will eventually wear off.


Please DO NOT GRIND SOFT MATERIALS ON THE BENCH GRINDER
