Emco PC120 Turn

[m_c]

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)
