The global medical devices market size was valued at $425.5 billion in 2018 and is expected to reach $612.7 billion by 2025, grow at a CAGR of 5.4%. More than 180,000 U.S. companies are involved in designing, developing, manufacturing, testing, marketing, packaging, and distributing medical devices in this thriving market. Today's Medical Developments serves the need of manufacturers and design professionals in medtech by featuring products, services, and techniques to help improve design and manufacture processes.
I was in manufacturing and inpecting similar ones at W E Sykes, a gear cutting machine tool manufacturer, who also made gear shaper cutters, hobs, shaving tools, standard gears (for gear rolling tests; e.g. Parkson) and some gear measurement equipment. The front angle is probably 5 degrees, dish ground. If there is a second angle, it s only to reduce grinding wheel wear when re-sharpening. The clearance angle, relative to the axis, is probably 6 degrees. Note; all from memory.
The shaper cutters can take a lot of resharpening on the front face before they are beyond use.
