Professional long-bed knife sharpening and grinding machines for industrial straight knives and blades, with Siemens PLC control, automatic grinding cycles and grinding lengths from 1,000 to 7,100 mm and longer on request.
The MVM KS250 and KX250 are professional knife sharpening grinding machines designed for industrial workshops that need to sharpen long straight knives and blades accurately and repeatedly.
Both machines are available in grinding lengths from 1,000 mm to 7,100 mm, with longer special configurations available on request.
Siemens PLC control, automatic grinding cycles, variable carriage speed and substantial machine construction make the KS250 and KX250 suitable for professional sharpening applications where long blade capacity, repeatability and controlled grinding are important.
The KS250 and KX250 are designed around long industrial straight knives where a compact knife grinder does not provide sufficient grinding capacity.
Their long-bed configurations extend to 7,100 mm, while special versions can be produced for applications requiring even greater grinding length.
The carriage runs on low-friction sliding surfaces and is driven by a toothed belt for smooth movement throughout the sharpening cycle. Variable carriage speed allows the grinding process to be adjusted to suit the workpiece and application.
Both machines provide professional long-length knife grinding, but the KX250 adds greater standard motor power and additional capability for surface grinding.
The KS250 is the professional long-bed model for sharpening industrial straight knives and blades, with a standard 5.5 kW grinding motor.
The KX250 is the higher-power version, with a standard 7.5 kW grinding motor and the additional ability to perform flat and surface grinding on plates and mechanical components.
The MVM KS250 and KX250 use Siemens PLC control to manage the grinding process and carriage movement through the working cycle.
On the KS250, programmable cycles include roughing, finishing and spark-out, allowing the machine to perform repeatable grinding sequences with less repetitive manual adjustment.
The KX250 combines PLC-controlled automatic operation with a higher-power grinding system for demanding knife sharpening and precision surface-grinding applications.
MVM specifies the KS250 and KX250 for a broad range of industrial straight knives and blades used across timber, paper, recycling, converting and manufacturing environments.
Suitable for long industrial knives used in paper and paper-converting applications.
Configurations are available for industrial straight knives used in timber processing and related blade-sharpening applications.
Suitable for long straight blades used in plastic recycling and granulating applications.
Long grinding capacity makes the KS250 and KX250 relevant to veneer and wood-peeling knife maintenance.
Professional grinding capability for long straight cutting and slitting blades.
MVM lists suitable carbide-edged industrial blades among the applications for these machines.
The KX250 extends beyond knife sharpening and can also be used for precision flat grinding of steel plates and other mechanical components.
Its higher standard motor power and available motor upgrades make it the stronger choice where a workshop requires both long-knife sharpening and surface-grinding capability from the same machine.
