CNC Gear Cutting Machines 3 Axes CNC Gear Hobbing Machines

PHA Series

PHA series CNC gear hobbing machines developed for autocomponent manufacturers and engineering industry in India.

PHA series machines are capable of cutting spur gears and helical gears up to 10 mm module. Crown hobbing and taper gears are also possible. Suitable for shaft and ring type of components.

PHA series can be offered with Electronic Gear Box (EGB) & Quick Hob Arbor Clamping (SK40 Taper).

PHA–250 EGB

This is the most popular model in the gear cutting machine in its category. Developments have been introduced to reduce noise of the machine and a new Siemens 828 D control has been added.
