Inca Geometric provides answer to trapped swarf in automotive parts cleaning system

Chartham, Kent-based Inca Geometric has retooled a special purpose four-station automotive rotary washing machine for cleaning the oil feed holes in crankshafts and will strip down the existing equipment on the production line and re-commission the process during the summer shutdown.

Explains managing director Michael Cain: "The existing set-up had problems with swarf being trapped from the drilling operation and, due to general wear from the 22 sec continuous production cycle running 24 hours a day, positive location of the crankshaft had also become unreliable." Inca has completely re-engineered the eight fixtures, redesigned the workholding, using hardened location pads to interface with the existing gantry loading system. Six high pressure jets have been positioned on the underside of each fixture and two above, which align with the feed holes in the four cylinder-engine crankshaft. Once in position, 6 bar coolant pressure from a filtered supply will be applied to each hole.
