- Heavy roughing of tough material
- Power milling of turbine parts and structural-components as well as air foils featuring MILLTURN operation
- Platform spindle for customization
- Suitable for swiveling axis thanks to compactness
- Best thermal stability thanks to OptiCool Principle
- Highest dynamic stiffness capable of working long tools
Energy
Machining of functional parts in one casting requires long tools to reach into deep cavities, produces high chip volumes, and calls for a most rugged Spindle design with greatest dynamic stiffness. Step-Tec Spindles’ excellent price/ performance ratio, superb ratio of performance to compactness, energy efficiency and – especially - our long term reliability give you the cost advantage you need. That’s why Step-Tec Spindles are manufacturers’ first choice for energy applications.
