Gear Hobbing Features

Worm Gear Cutting:
- Worm Gears are similar to screws, with teeth in a 360 degree profile. They have a high gear ratio in a small space.

Bevel Gear Cutting:
- Bevel gears are conical in shape but do not extend to their vertex.

Rack and Pinion Gear Cutting:
- Rack and pinion gears have a rack, or toothed rod operated by a pinion gear converting torque into a straight line movement.

Helical Gear Cutting:
- Helical gears have angled teeth that provide for a slower, smoother motion.
