Surface grinding machine FX 80

for straight bladerotating tablewith fixed table

Product overview
The FX 80 is an industrial grinding machine designed for the high-volume production of blades, knives and for surface grinding of large workpieces. It features a 700 mm working chamber width and is offered in working lengths from 1,500 mm to 7,100 mm (extendable on request). The machine is equipped with a 55 kW grinding motor and can be configured with rotating or fixed electro-permanent magnetic tables.
