The spindles with permanent grease fill with “T” indication do not need additional lubrication during operation. The bearings are greased with high-revs quality grease. The lid labyrinths are full of plastic grease that resists common cooling liquids used during grinding.
The oil-mist lubricated spindles need a misting machine for operation. For the grinding spindles with belt drive, the MP4 misting machine manufactured by ČZ is available as well.
Driving grinding spindles with belt drive
The spindles are dextral (when viewed from the belt pulley, the spindle rotates clockwise) and anti-clockwise spindles are available upon special request.
Woven flat belts or plastic of uniform cross-section and minimum seam or final woven are used for driving the spindle. The belt pulley diameters are calculated for an electric motor drive of 2865 mm-1 revs with A220 belt pulley. To drive the spindles at 50 000 and 60 000 min-1 revs, a higher-frequency motor or PD 14 gear is required.
