A complete systems approach to integral motorized spindles for milling, boring and grinding

• A drop-in unit that replaces other major brands with a more powerful, liquid cooled (TELC) motor. TENV is available.
• Embedded thermistor motor protection senses overheating conditions before serious damage occurs.
• System components; spindle, variable speed AC drive and spindle cooling chiller/circulator have been matched for optimal compatibility. The variable speed drive programming has been optimized for each motor size.
• MT spindles, like all SKF Precision Technologies spindles, achieve their accuracy through precise manufacturing of each component in the assembly, not by grinding the assembled spindle into spec.
• HP at Max RPM is S1-100% Duty Cycle Rating (24/7/365)
