650XBT50

650X CNC Spindle Series

Integration of the popular BT50 tool holder into the 650 spindle housing delivers constant high speed with ultra-low vibration and improves accuracy and rigidity. Rigid steel construction in one piece with the tool holder also cuts the height of the unit. With Air Turbine Spindles® patented double turbine’s extra power the 1.4 hp (1.04 kW) motor maintaining stable high speed and torque under load. The 650XBT50 accelerates feed rates and cuts cycle times as a result of its low friction power unit with few moving parts. Rated governed speeds available are 25,000, 30,000 and 40,000 rpm. Plenty of power to speed up your inches cut per minute. High cutting speeds are maintained at the periphery of your end mill or burr using the 650’s unique governed performance to achieve a faster cycle time, a cleaner finished surface, and more production on your CNC. No Duty Cycle.

Automatically Tool Change on your CNC

Block and Collar on the Automatic Tool Changer Assembly

Automatically load Air Turbine Spindles® in CNC machines with our patented wrap-around Toolchanger Mounting Assembly (TMA). This option allows CNC tool-changers to automatically load/unload our family of high-speed precision spindles using a proprietary collar system and mounting block or ring around the CNC spindle integrated to the right side of the CNC spindle in minutes.

Drill Tap

Mounting blocks or rings compatible with Haas, Hurco, Doosan, Robodrill, Hardinge, DMG, Brother, Okuma, and all other CNC’s are available. We are accustomed to developing custom solutions for any CNC. A Universal Block can be provided for drilling your CNC screw positions. Installation Kits are available. The TMA block remains on the CNC spindle for normal tool changes, even if not using the Air Turbine Spindles™ as it will not interfere when using the main spindle.

TMA Assembly Includes

  1.  Mounting block or ring assembly
  2. Spindle manifold collar with adjustable height connector to block
