The new P20 CNC is the world’s first CNC profile grinder, from Colonial Saw. Colonial says this is a fast, powerful grinder that requires no templates. The machine accurately rough-grinds from blank knife to finished profile, right from DXF CAD drawings. Features a 10 hp grinding motor with variable speed control. Colonial sans the P20 is five times more powerful than standard manual profile grinders. The unit has four CNC digital servo motor-controlled axes. It automatically compensates for compound side- and back-clearance angles. Quick-change cutting wheel grinds against the cutting edge only. This limits any burning to the bottom of the grind.
