The Hunger PHM is designed for precision honing of cylinder liners up to 640 mm diameter right on the engines or on a stationary base in workshops.

   Honing diameter up to 640mm

Air operated machine.

Rotary motion and linear stroke motion of the honing head are infinitely variable through simple regulation of air supply to obtain the desired crosshatch surface pattern.
Stone pressure is also infinitely variable through regulation of air supply to the stone pressure actuators.
When air supply to the stone pressure actuators is shut off, the stone holders will be retracted so that vertical scratches in the cylinder liner wall can be avoided when the honing head is removed from the cylinder liner bore.
