Special Tools

Edge honing device

The manual honing device can be used to hone blades with all types of angles. Honing is carried out using 4 rotating Arkansas stones (natural stone). The final result does not depend on the operator.
The device is fitted with a scale.
Ideal for honing guillotine or cutter blades guaranteeing:

• durable sharpness

• reduction in bur formation time

Magnetic chuck for HM knives

The magnetic chuck is suitable for straightening out Widia (HM) tools, used for woodworking. The chuck has a strong holding power because the small knives are positioned directly on the magnets so even very small pieces can be resharpened. It is particularly suitable for linear or surface grinders because the supporting bed is parallel to the magnetic surface.

The magnetic chuck can be :

a) secured to any type of magnetic chuck ;
b) fixed mechanically by means of the four holes around the edges.

The chuck is available in two sizes :
1) mm 200 x 70 x 20
2) mm 400 x 70 x 20

By aligning or flanking a number of magnetic chucks, extremely strong magnetic surfaces can be obtained. 

Portable Refractometer

MVM has been manufacturing knife sharpening and surface grinding machines for more than 40 years, and now offers to its present and future customers a new type of refractometer.

A refractometer is a tool used to measure the concentration of a water solution by measuring its refractive index.

This portable and practical instrument is a must for anyone using grinding machines who needs to check the oil concentration in the coolant solution used in grinding machine.

The range varies from 0 to 10 (BRIX) and allows MVM machine users not to go over the correct oil to water percentage of 1.5% to 2%.

The use of this instrument is extremely important because if a grinding machine operates with a concentration of oil higher or lower than the recommended percentage this could cause problems which are well-known to everyone in this sector. 

Corundum Stone

An aluminium oxide stone with various granulometries.We suggest the use of the double grain version (180/500) for a wide filed of application.The colour (orange, brown, blue) is due to the oxide content, which confers a high level of toughness to the stone.Stone for sharpening particular worn out tools, suitable for use by inexperienced people.We suggest the use of this stone before finishing with natural stones.

APPLICATION: dry, oil, petroleum or water.
CLEANING: rub stone with sandpaper and water.

Natural Stone

Quartz is one of the most abundant materials in nature. However only few natural stones have the correct quartz-carbonate (bonding agents) ratio; a perfect balance that makes these natural stones exceptional for sharpening. The natural characteristics of these stones are enhanced by the use of water which, reacting with the lime, removes it slightly, leaving the abrasive quartz permanently exposed. This means that the stone can be immediately and perfectly cleaned, maintaining its abrasive characteristics. Qualities of the natural stone: high quartz content with homogeneous distribution of the sharp-edged quartz grains (measuring only a few tenths of a Micron), that provide a high level of abrasiveness and long term use. This type of stone is easy, and clean to use, durable with constant performances.

APPLICATION: with water.
CLEANING: leave stone to soak in water and vinegar for 12 hours.

MVM s.r.l., proposes to its customers a mechanical multifunctional clamping device for “disposable” blades, apt to be installed on MVM knife sharpening machines.Each device is for specific use with one kind of blade, for example Tersa, Centrofix, Weining etc.All the faces of the blades are rectified and this together with a special clamping systems allows the tool to b easily mounted or removed from the grinding machine.We guarantee a parallelism between the centering groove and the cutting edge of 0.02 mm/m.
