The external broaching head has been developed to produce primarily hexagonal forms on turned parts during the turning cycle on capstans, autos, CNC lathes, etc.
Recommended feed rate 0.0015”-0.002” per revolution. Spindle speeds 885-1500 rpm pre-turn bar by 0.010”-0.015” below A/C dimension minimum. Chamfer to A/F diameter minimum.
At present for use on mechanical feed type machines only. Depending on material and work holding facilities, designed to produce 3mm-16mm (1/8”-5/8”) A/F hexagon with length of flats 1.5 X A/F max. It is also possible to produce squares with limited application. The external broaching head complements the internal head and is available with various shank diameters, including VDI.
