This circular knife grinding machine combines the following three main features:
for grinding bevelled circular knives and blades and surface grinding discs and other work-pieces
Also available is the version LA 700 for grinding circular blades and discs with diameter up to 700 mm.
Technical features of the LA500 circular knife grinding machine:
The model LA300 is a grinding machine for sharpening circular blades and counter-knives. Practical, covenient and compact the LA 300 is easy to use.
The LA 300 can sharpen circular blades up to 300 mm in diameter and features a 0° -70° rotating grinding head, grinding motor power of 1,5 kW, automatic working cycle, and variable speed blade support.
The LA 300 is particularly suitable for sharpening blades used in the tissue sector.
LA 500/90 spindle with a horizontal axis is a grinding machine for external diameters up to 400 mm.
The set up of the machine provides for a system for adjusting the working position of the spindle to vary the outside diameter of the disc to be ground, so as to always maintain the optimal point of contact between the abrasive and work-piece.
Also available LA700 / 90 for outer diameters up to 700 mm.
The same machine, fitted with rotating magnetic chuck up to Ø400 mm, allows surface grinding the plane of the blades or mechanical components, the sharpening of circular blades and single or double counter-bevelled blades, in addition to the external grinding of discs at 90°.
The system ATK is an innovative, revolutionary and unique grinding machine, that is able to combine into a single professional machine the capability of sharpening both straight and circular blades.
This innovation is made possible by using the ATK system, that has been patented by MVM in 2014, that features a motorized rotary axis that is adjustable from 0° to 60°, for sharpening circular blades and counter-blades up to max Ø 300 mm. This new system can be mounted on our linear grinding machine models KS250, KX250, FX20 and FX40.
This new unique hybrid grinding machine allows the re-grinding of two very different types machine blade, therefore maximizing production efficiency and increasing the investment return on the machine purchase.
This application is suitable and recommended for professional grinding centers and for the tissue industry and paper mills.
Tool for sharpening and fixing mincer blades up to a maxmum Ø = 300 mm with centering flange hub for reversible blades. It is possible to work the recess angle up to 15 ° and the cutting angle at 0 ° on each blade. Mobile reference for rapid blade change, rotation stop for angle sharpening.
System for centering and locking flange for flat mincer blades with all cutting edges of 0 °.
Tool for sharpening and fixing mincer blades up to a maximum Ø = 300 mm with retractable centering expansion for non reversible blades. Ability to adjust the recess angle up to 15 ° with locking brake for angle sharpening and mobile reference for blade changes.
Centering system for grids and flat plate mincer blades on rotating magnetic chuck.
TP 500 is an additional head for cleaning and polishing circular chamfered or toothed discs.
This is useful to remove any kind of residue build-up from the body of the circular discs and bevels (oxidation, resin, scale, stains, etc).
TP500 is an option for the LA500 and LA700, so they can be used as both as a circular blade grinding machine and as cleaning and polishing machine for circular discs.
