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 ;-)
Safety
(Breathing protection recommended depending on bit and material)
| 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 |
| shavings (especially steel) are very sharp & hot, parts of the machine/workpiece can become hot | |
 |
if the power has been lost for whatever reason, always turn the switch "off" before restoring it! |
Precautions
which danger do these belong to?
- keep transmission covers closed during operation
- compound slides move 0.2mm per 1/10 of a revolution (1 indent)
- radius reduces twice as much
Demonstration
The tutor will show you these steps in detail:
Function and Maintenance
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
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!
