MVM LT500 Circular Knife Grinder for Industrial Sharpening
The MVM LT500 is an automatic circular knife grinding machine designed for bevelled circular knives up to Ø500 mm, as well as single and multiple counter-blades. Its rigid construction, motorised working axes and programmable grinding cycle provide the control needed for repeatable industrial sharpening.
A standard Ø250 mm tangential grinding wheel is complemented by an optional Ø150 mm face grinding wheel for suitable frontal-grinding applications. Siemens touch screen PLC control, precise electronic handwheel adjustment and variable table speed allow the grinding process to be configured around the knife geometry and required finish.

Grinding applications
Automatic Circular Knife Grinding for Bevelled Knives & Counter-Blades
The LT500 is designed for industrial circular-knife work where controlled bevel grinding, accurate positioning and repeatable automatic cycles are important. The grinding setup should be selected to suit the blade geometry and material.
Counter-blade sharpening
Single & Multiple Counter-Blades
The machine accommodates single and multiple counter-blade arrangements. A suitable grinding-wheel and workholding configuration can be selected for the knife set and required edge.
Industrial blade maintenance
Repeatable Automatic Grinding
Programmable cycles, PLC control and precision adjustment make the LT500 relevant to specialist sharpening workshops and production facilities maintaining circular cutting tools.
