“The main benefit is this is that it’s full CNC, so the learning curve of your grinder person goes down. You don’t need someone with 20 years of experience in the grinding industry to put out good product. You can train anyone to run it,” product manager Jeff Goltz says.

The machine rough grinds a blank knife into a finished profile directly from DXF or HPGL CAD drawings. Templates are not required. It features a 12-hp grinding motor and variable-speed control, according to Colonial Saw.

“The reason you want variable speed on a machine like this is because some people are still running high speed steel and others are running carbide,” Goltz says.

“With four CNC digital servo motor controlled axes, it automatically compensates for compound side and back clearance angles. The full cabin enclosure is significantly safer than manual knife grinders. The quick-change grinding wheel grinds against the cutting edge, limiting any burning to the bottom of the grind.”

Goltz adds that the machine also helps shops eliminate inventory.

“If you’re having somebody now do your sharpening for you, you need certain sets on hand depending on the job. But now you don’t need them because you can make a brand new set in 30 minutes.”

The machine retails for $150,000 to $160,000, depending on the tooling specified.
