Colonial Saw Inc. recently introduced its UT.MA P20 CNC, which the company calls the world’s first CNC profile grinder.

The UT.MA P20 CNC Profile Grinder can be used for manufacturing or regrinding profile tools. It is also a complementary finishing machine for those who rough grind with a waterjet. The company says moulding and millwork businesses use the P20 CNC to grind custom knives in the original heads (including Powerlock heads), while toolmakers use it for mass production of HSS moulder knives, carbide inserts, brazed cutterheads and router bits.

The UT.MA P20 CNC’s 12-horsepower grinding motor with variable speed control is five times more powerful than standard manual profile grinders, according to the company. The machine rough grinds from blank knife to finished profile directly from DXF or HPGL CAD drawings. No templates are needed. The machine also comes standard with a PXCAD, a 2-D drawing that allows the user to create a CAD drawing of a tool profile or to finish drawing from an electronic scan of a wood sample or a non-dimensioned line drawing.

With four CNC digital servo motor controlled axes, the UT.MA P20 CNC automatically compensates for compound side and back clearance angles.
