ACRA-BORE 2000 Specifications


Heavy duty inclined
bed allows for easier operator access to jig and uninterrupted passage of chips and coolant to swarf tray.

Robust headstock

Vari-speed Drives used to spindle and feed, controlled by two quick change, eight position switches. Both set on corresponding numbers give the recommended feed rates per revolution of 0.584mm (0.023"). Vari-speed drives give slower start up revs and feed for initial cutter entry and then increasing to a higher speed and feed giving faster throughput of cylinders without chatter.

Spindle has 2 ½" brake tube capacity. Coolant nozzle, fixed to tool slide, follows parting and chamfering tools. No time wasted resetting nozzle to tools.
