Highly efficient, multi-functional and easy operate, this specialized grinding machine is specifically designed for CNC turret punch press punches and dies, it can also be used in the grinding of other punches, die plates and cutting dies, The main motor, coupled with a rotating angular joint directly drives the grinding head. The grinding head is cooled by internal coolant spouts to ensure sufficient cooling of dies during the grinding process. A cam ring chuck can be fitted on to the rotating angular table. The clamping device can be adjusted from zero to ten degrees: and be rotated 180 degrees for the grinding of rooftop shears or single sloped “whisper” shears.
