Linear knife sharpening machine grinding a long straight converting blade
Industry Application

Knife Grinding for Paper Film and Plastics Converting

Long straight knives ground flat, straight and to the same angle every time.

Industry Pain Points

Three Problems That Bring Buyers to Us

Long Blades Do Not Fit Any Standard Grinder

A 2000 mm guillotine knife has nowhere to sit on a surface grinder table, and repositioning it halfway destroys the reference.

Mechanical Clamps Bow Thin Blades

Clamping a thin blade introduces exactly the bow you are trying to grind out. Magnetic holding across the full length avoids it.

Edge Angle Varies Between Regrinds

A hand ground edge is never the same twice, and cut quality moves with it. Setting the head angle makes the regrind repeatable.

Converting plants need full length blade support, repeatable edge angles, and traverse speed control so blade steel is not burned during grinding.

Questions

Paper and Plastics Converting Questions

What blade length can you handle?

Up to 2000 mm on the WK2000, and up to 700 mm with 650 mm effective length on the WK700.

How is a thin blade held without bowing it?

On a 180 x 2000 mm magnetic table that supports the blade along its full length.

Can you build a machine for longer blades?

Table length is one of the things we modify. Send your blade dimensions and we quote the build.

What edge angles are possible?

Minus 90 to plus 90 degrees on the WK2000 and 0 to 90 degrees on the WK700.
