This is the content required for an introduction to our metal lathe - 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: Patrick, Johannes, Luzian
Safety
| Dangers | Precautions |
|---|---|
 |
|
| loose workpieces can be thrown at high speeds |
|
| small debris can be thrown towards the user | a face shield in addition to goggles is recommended |
| cluster of shavings ('rats nests') can be caught by the chuck => very sharp; quickly rotating object... | regularly remove shavings around the chuck (with the machine turned off) |
| autofeed will cause a crash if left unattended! | never leave the machine unattended, especially when working with autofeed |
| belt drive will crush your fingers if the motor is tuned on while changing the transmission ratio | to be safe at least turn off the main switch AND the motor-circuit switch if not unplugging the machine |
| shavings (especially steel) are very sharp & hot, parts of the machine/workpiece can become hot | Don't try to remove shavings by hand. Stop the machine and use a pair of pliers or brushes. |
 |
if the power has been lost for whatever reason, always turn the switch "off" before restoring it! |
Demonstration
The tutor will show you these steps in detail:
Function of Dials
- compound slides move 0.2mm per 1/10 of a revolution (1 indent)
- radius reduces twice as much
Change Gearing
Change and Secure a Workpiece
Tooling
Turning a Piece with and without Autofeed
- turn a part to size
- outside diameter
- inside diameter
- drill a hole
Cleaning up
- loosen the belt tension
- unplug the machine
- remove the chips
- cover up the lathe
Waiting List
This introduction takes longer than many others and usually can't be done spontaneously during regular opening times. If you would like to receive it, please add yourself to >> this list << and we will find a good time once a few members are on it!
