This is a Colchester Master 3250 metal lathe, used for many kinds of turning operations on (mostly round) metal parts

The lathe is ACNode controlled and requires training. For information on the training process see Lathe Training

For some information on the current range of tooling and accessories, see Metal Lathe Accessories

A few house rules for using the lathe:

• No wood (sawdust gets into all the moving parts, soaks up moisture and oil and then becomes quite abrasive)
• No use of compressed air for cleaning (it sometimes drives chips past the chip guards and into the moving parts)

When you are finished with the lathe please ensure all chips are removed from the ways and carriage - first by brushing down with a brush, then hoovering using the nearby wet & dry vacuum, then finally wiping down with a rag

Maintenance

Check coolant levels preferably before the coolant pump stops pumping. If it reaches that point, the reservoir can take a little over ~20L of 5% coolant diluted down with tap water: measuring jug & funnel can be found atop the big blue plastic jerry can of concentrate under the bench in the toolstore. There's a white 5L jerry can nearby for premixing (and may contain leftover) 5% coolant.
