This is the content required for an introduction to our bench grinders - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)
If you need this introduction, please reach out to the following tutors: Lukas, Luzian, Patrick, Sebastian, Johannes, Utis
Let's begin! First off, make sure you have read the machine's wiki page and manual, where available (see InfoBoxes).
Safety
(Breathing & hearing protection recommended depending on material and duration of work)
| Dangers | Precautions |
|---|---|
| dry grinding: generation of hot sparks that are expelled in varying directions |
|
 |
wear suitable gloves to prevent burns from sparks or the workpiece when you remove a lot of material |
| dry grinding: sparks can fly far and deposit themselves as fine dust, metal dust can be a health hazard when inhaled | wear proper breathing protection if your material is harmful when inhaled |
| aluminum can clog an abrasive wheel and cause it to overheat until it breaks | do not attempt to grind aluminum |
| the workpiece can get caught on the wheel and get jerked from your hand |
|
 |
if the power has been lost for whatever reason, always press the "off" button before restoring it! |
| the blades you are sharpening become sharp... | do NOT test the sharpness with your finger or other body parts you want to remain intact |
Wet Stone Grinding
- Before you start:
- Ensure the water trough is filled properly with cold water before you start to grind (there is a "MAX WATER LEVEL" sign).
- Tighten the knob on the front of the machine (turn it clockwise until the wheel begins to drive)
- Keep an eye on the water level during grinding. Refill if needed.
- Do NOT grind a blade with the stone being dry.
- When you are done:
- Remove the water. The stone is not supposed to be kept wet!
- Disengage the drive system with the knob (turn it counter-clockwise) on the back of the machine.
