Emco PC120 Turn

Yes, just lop off the spare, the manufacturer would originally have sold you some (very expensive) tools made for the machine but whatever works is good,

Great, thanks. I posted on some youtube videos where others are running these machines and they all did the same.

I noted one guy actually runs his machine with standard right hand tools but has them upside down. The manual shows this is possible. Downside is probably not as easy to get coolant onto the cutting area, not sure of any other reason to do this.

Rear turrets usually run tools upside down, otherwise you lose time having to reverse the spindle every time you want to drill. Getting coolant into the tool is not a problem.

Thanks. Where / what determines the direction of spindle rotation per tool?

Where the cutting edge is, and what direction the material has to turn in relation to the cutting edge. The turret on my lathe is rear mounted with the disc machined so 12mm tools have their cutting edge level and facing down when at the spindle (click the pic if you want to see a vid of it changing position a couple times)

Sorry, my question was unclear.

I understand when I need CW and when CCW. What 'setting' tells the spindle to rotate CW or CCW depending on the tool choice?

There's not a setting for that. You'll need to ensure however you produce your G-code does the spindle direction setting.

You could allocate blocks of tool numbers that rotate certain directions, then use the M6 macro to check and set spindle direction depending on tool number.

Great, I was thinking it might be CAM based. Ill check the settings in Fusion 360. That said, if I run everything 'upside down', I can stick to CW which suits drilling ops. Will also save me from buying a new 16mm boring bar as I can use what I have.
