Sharpener for narrow band saw blades OW-4

The machine sharpens the band saw blades semi-automatically. The tooth parameters are being changed manually. Grinding wheel is driven by motor but feed of the blade is driven by motoreducer. Smooth adjustment of grinding wheel stroke (up-down) gives the possibilities of adjustment of different tooth heights. The basic tooth pitch is 22 mm (other pitches to individual order)

The machine is equipped with a cam which enables many modifications of the tooth profile by various combinations of the positions of the driver.
One rotation of the cam completes the sharpening cycle of one tooth.
The sharpener is equipped with a pump to cool the tooth during the sharpening process.
The machine must be set steadily or fixed to the floor.
