15HP Collet

Divider

XR-15 Collet, Manual/Wrench Type

  • spindle1515HP rated at full 480V-3 phase
  • Operating range 3600 rpm to 18,000 rpm
  • Aggressive plunge rates, fixed pre-load (up to 600 in/min)
  • 1” diameter capacity, manual change

Housing & Construction

  • high strength (32,000 tensile) cast iron outer housing to help maintain internal precision alignment;
  • 15HP motor pack supplied by E+A (Switzerland), also used by spindle giants Fischer & IBAG (4-pole, full torque @ lower RPM)
  • cast iron provides unmatched system rigidity, quietness of cut and quality edge finish, maximizing tool & bearing life (compare to cheaper die-cast housings);
  • heat shrunk rotor for ideal internal balance;
  • upper and lower balance rings that are precision balanced;
  • balanced to 80 decibels as measured at our plant at full speed/no load;
  • Supplied with closed-loop auxiliary chiller, dust hood, eight collets each (customer specifies desired sizes);

Bearings & Lubrication

  • two duplex 50 mm ID ceramic lower bearings;
  • two duplex 40 mm ID ceramic upper shaft bearings;
  • micro spray mist oil lubrication to the bearings (superior to grease which can contaminate bearings).

Standard Sensors for Worry-Free Operation

  • sensors to detect desired coolant flow;
  • heat sensors to avoid high internal heat;
  • low level sensor in the spindle oil lubricator to detect when oil needs to be added;
  • These sensors will automatically help avoid costly mistakes or oversights.
