Manually programmable, fully automatic cylinder spin grinding with automatic traverse and in feed.Allows the operator to program the machine and then carry out other work when spin grinding. The cylinder can be returned to the original manufactures specification.
Grinds both top & front faces of the bottom bladeBottom blade returned to original manufacturers specification.
Takes data measurements from cylinder shaft.Eliminates cylinder coning especially important on cutting units with fixed cylinders and rear rollers.
Cast iron bed constructionReduces vibration and increases accuracy
Liquid coolant on all operationsReduces air borne dust therefore no need for extractor fans. Stops heat build up and distortion.
240 volt power supplyCan be readily plugged into normal 13-amp power supply.
Linear bed rails with self-adjusting bearings. Accurate & smooth traverse of the grinding wheel carriage to within 0.05 mm or 2 Thou. over the width of the machine. Low maintenance requirement.
Slow/Soft start spin grinding motor.Avoids shock starts and cutting unit dislodging.
Flexi drive to cutting cylinder.Less vibration and allows for any misalignment in setting up.
Bearing pack Contains 6 pairs of bearings and holders for out of situ cylinder grinding
Universal bracket packAllows all types of cutting unit to be mounted without the need to dismantle.
