Why is the industry considering changing from well-established gear manufacturing processes to something that is much more complex at first glance? Gear manufacturing has been its own “world” in metal cutting, dominated by companies with very specific expertise around gear technology. Production output has been high, but flexibility is limited. The technicians running these machines are highly skilled, but recruiting new staff with these skill sets has become more and more difficult.
Gear skiving offers great opportunities
for production with step-changing
productivity, particularly for internal gears,
whilst offering high-quality finishing
capabilities and being applicable on a
5-axis machine tool with its inherent
flexibility and multifunctionality.
Mitsubishi Heavy Industries, Ltd. (MHI) conducted a comparison test between the super skiving cutter and the pinion skiving cutter used in the conventional skiving process and the test results are reported here.
Automotive gear manufacturers have implemented significant improvements in external planetary gear manufacturing yielding quieter gears. In addition, process stability has increased due to the post-heat treatment finishing processes employed. This article explains various complete solutions for cutting and finishing internal ring gears.
Call it new wine in old bottles, or old wine in new bottles, but
gear skiving has certainly aged well over time. Gear skiving's evolution, perhaps gaining momentum most dramatically since around 2004, has ultimately led to rather dramatic technological advancement and cost saving in the manufacture of certain gears.
