Nobur® JA Series Automatic Recessing Tool Allows Faster Production Time

Cycle time is reduced by more than 94% as Nobur Recessing replaces circular interpolation for grooving operation manufacturer of hydraulic valves had to machine two O-ring grooves in a spool valve bore. They were circular interpolating one groove at a time with a key slot cutter. The approximate cycle time with this method was six minutes per part.

The grooving operation was a bottleneck in their manufacturing process. With the use of the Nobur JA Automatic Recessing tool from Cogsdill, both grooves were machined simultaneously for a total cycle time of only 20 seconds per part.

The customer­s fixture holds 16 piece parts; for grooving all 16 parts, the total cycle time is reduced from 96 minutes to 5.33 minutes, for a total cycle time reduction of more than 94%!
