CNC Gear Cutting

Richardson Manufacturing Company is pleased to offer precision gear cutting capabilities for a variety of industries which include but are not limited to industrial equipment, mining, oil & gas, and heavy construction. These capabilities include state of the art CNC hobbing, shaping, and gashing machine equipment. The hobbing machines can accommodate parts with a diameter of up to 78.7” (2000 mm) or a max axial face width of up to 46” (1168mm), with gear teeth as large as 1.6 D.P. (15.88 module). RMC also has heavy-duty manual and CNC shapers that can accommodate parts that are up to 69” in diameter, 60” tall, and cut gear teeth as large as 1 D.P. (25.4 module) with up to 17” of stroke length. Lastly, the 2400 size gear Gasher machine gives RMC the capability to perform either external hobbing or gashing (rough or finish applications) of spur and helical gears up to 78.7” in diameter with an axial stroke length of about 69” (1760mm). This machine is also configured with an internal gashing head that can cut internal teeth of parts up to 94.5” (2400mm) in diameter. We can work with a wide range of materials depending on customer needs, from prototype to production. Our state-of-the-art gear inspection equipment can perform full analytical gear inspection to verify the quality of the parts produced to ensure meeting the specifications required by the customer.

Lastly, a recent addition of our gear cutting capacity includes a new 2400 size hobber/ gasher machine. This gives RMC the capability to perform either external hobbing or gashing (rough or finish) of spur, helical, or double helical gears up to 78.7” (2000mm) in diameter with an axial stroke length of about 69” (1760mm). In addition, this machine is also configured with an internal gashing head that can cut a part up to 94.5” (2400mm) in diameter. We can work with a wide range of materials depending on customer needs, from prototype to production. Our state-of-the-art gear inspection equipment, newly equipped with the AGMA2015 standard, or other standards as required, can perform full analytical gear inspection to verify the quality of the parts produced to ensure meeting the specifications required by the customer.
