650CAT40

650 CNC Spindle Series

The 650CAT40 delivers governed constant high speeds under load – 25,000 to 40,000 rpm, < 0.88 hp (0.66 kW). Robust and reliable, with double front ceramic bearings, the 650 Series is ideal for heavier duty applications and milling hard materials in corners. The governor-controlled turbine maintains rated high speed, optimizing tool performance and life. Effective in all materials, including tool steel, titanium, and ceramic. Ultra-low vibration and no heat in 24/7 operation. Selectable rear or side air feed on each spindle. Automatic Loading from the magazine on all machines.

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.

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
