625XCAT40

625X CNC Spindle Series

The patented double turbine 625XCAT40 delivers constant high speeds under load – 30,000 to 50,000 rpm, < 0.76 hp (0.57 kW). Speed up your cycle times with this compact and powerful spindle. Ideal for contouring, mold making, milling, finishing, and drilling with small tools. Governor control maintains constant high speed and power under load. Direct drive means no heat, no duty cycle, and super reliability. Selectable rear or side air feed.

Retrofit Any CNC with High Speed

We retrofit any CNC machine to mill at a constant high speed 24/7 – so any CNC can be a high-speed machine. This includes, but isn’t limited to DMG MORI, Haas, Fanuc Robodrill, Doosan, Hermle, Hurco, GROB, Brother Okuma, Makino and Mazak. Easy installation using selectable air feed inlets – choose side inlet NPT / Stop Block or center through shank/tool holder air feed. HSK, CAT, BT, and DIN Toolholder options are available.

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.

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
