602 CNC Spindle Series

Integration of the popular HSK-E40 tool holder into 602 spindle housing cuts vibration and improves accuracy and rigidity. Rigid steel construction in one piece with the tool holder also cuts the height of the unit. Air Turbine Spindles® patented constant governed high-speed operation under load cuts faster and cleaner – speeding up cycle times and achieving major savings. Your solution for fast cutting with small end mills and drills, finishing or marking. High-speed cutting improves finish quality and accuracy with a fast light pass of your tool. At 40,000, 50,000, 65,000, or *90,000 rpm tool coatings achieve the required temperatures to extend endmill life-saving money as well as accelerating production. 0.2 hp (0.15 kW). No Duty Cycle.

*90,000 rpm 602 version is recommended for only special applications with micro end mills. Please call +1.561.994.0500 for more information.

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.

For machines that have an air blast line or coolant channel that can be used to supply sufficient CFM / L/s airflow volume;  Air Turbine Spindles can tool change without the Toolchanger Mounting Assembly. All HSK spindles can be used with center air feed if air supply line has sufficient ID.

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
