Body and spindle models
− SM (small): small body, for light pieces and higher turning rates
− ST (standard): for normal loads
− SU (super): for heavy-duty loads and low turning rates
Type of spindle
− Type N/NH = standard point 60°
Loads
The weight indications for workpieces are based on the assumption that the workpieces are held between two Live-Centres and therefore one has to hold a maximum of 50% of the workpiece weight. Additional loads, for example, due to imbalance or due to uneven weight distribution, are not allowed.
Important
− Pay attention to the load diagram
− Live-centres with carbide tips may not be used with the maximum load.
Maintenance
All ROTOR Centres are manufactured with continuous lubrication.
Type N = hardened steel
