By replacing the time-consuming shaping process with power skiving, cutting time was reduced and tool life increased considerably. With an annual production of 500 pieces, the customer could save 112 hours worth of machining time per year, leaving space for a large amount of valuable free capacity.
Further benefits with the switch to power skiving were reduced tool set-up and indexing time, increased process stability and consistent component quality.
