Air Turbine Spindles
AIR TURBINE TOOLS RUN ON COMPRESSED AIR FOR 25,000-90,000 RPM. JUST 2 MOVING PARTS FOR EXCELLENT ACCURACY & PERFORMANCE
Air Turbine Spindles® turn a normal CNC machine to turned into a high speed machining center with a spindle speed of from 25,000 RPM to 90,000 RPM.
This is a must have for micro-tooling and delivers huge cycle time savings - typically around 80% time reduction.
We recommend and supply NS TOOL for micro tooling → NS TOOL (click to view)
With just 2 moving parts - Air Turbine Spindles are low friction, low vibration and low heat. This delivers super accurate performance as they have very little thermal expansion and vibration. This also means they don't have any parts to burn up and this is a huge improvement to high RPM life span.

20mm JS units combine with ER 32 or other toolholders for infinite compatibility.
Integrated Shank
For integrated shank mounting options select from CAT, DIN/SK, BT, HSK and many other integrated options to provide rigidity.
Tool Changer Mounting Assembly (TMA)
The TMA allows for air turbine spindles to be automatically loaded/unloaded into your CNC.
It is a proprietary collar system and mounting block that integrates to the right side of your CNC spindle. The mounting block connects to a clean airline and solenoid. Installation just takes a few minutes.
The Toolchanger assembly and mounting block is compatible with Haas, Fanuc Robodrill, Brother, Mazak, and most popular CNC/VMC machines.

Air Turbine Motors
Air Turbine Tools allow a normal CNC machine to turned into a high speed machining center.
450HD
Aluminum Motor Mount Series
Quadruple ceramic bearings, an ER 11 collet, and a rigid steel barrel for mounting make the 450HD ideal for cutting or finishing harder materials. Sealed at front collet for wet environments.
The durable direct drive governed motor make this unit a reliable workhorse. Powerful 24/7 performance with 0.88 hp (0.66 kW) at governed 40,000 rpm.
Very low vibration magnitude of 1.25 m/s² r.m.s, makes the well balanced 450HD ideal for robotic integrations.
Applications include finishing, drilling, milling and routing.
730MX
Steel Motor Mount Series
The popular 730MX is ideal for lab mills, lathes and swiss automation, and all fixture and robotic applications. Reach deep and run faster for accelerated production and cleaner cutting action.
Get finer finished surfaces with faster cycle times.
Lower vibration and greater reliability result from fewer moving parts in this direct drive, oil free geared double turbine motor.
Mountable area of 30mm by 95mm. Completely sealed with hose exhausts.
Air Turbine Hand Tools
Air Turbine Tools allow a normal CNC machine to turned into a high speed machining center.
0145SSV
Put the 0145SSV in your fingers or palm and experience exceptionally fine control necessary for close proximity work. Feather-light at 0.17 kg the 0145SSV has lots of torque.
This tool is effective for precision work, marking or deburring but its so light you hardly notice you are working. Our patented 45° design conforms to the natural position of your hand for hand- eye coordination.
Because the motor is in the 45° head there are no gears, vanes or brushes to vibrate or heat up. As a result the 0145 delivers direct drive reliability with only 2 moving parts combined with lower vibration and weight than a gear head.
201SV
You will immediately feel the 201SV's ultra low vibration and weight and hear the < 65 dBA sound level. The light 201 is powerful - designed to work reliably in industrial applications.

About
Air Turbine Tools® are high RPM tools that run on compressed air.
Patented Direct Drive constant high speed and torque - which remains high under load. Constant 25,000 to 90,000RPM up to 1.4 HP/1.04kW with optional double turbine power.
Governor controlled constant high speed and torque results in more inches cut per minute. Acceleration of the milling process saves hours. Speeding up the detail work results in great savings and frees up your CNC.
Fewer moving parts means less friction, less heat and lower vibration - important for accuracy. The 40,000 rpm 625JS vibration is just 0.28mm/s.
Superior accuracy. High speed and low vibration are good for accuracy. The spindle's steel housing is rigid and stable and air cools the ceramic bearings. Optional upgrade to 2 micron collet where desired.
Reliability 24/7 at high speed with minimal heat distortion. The grease packed ceramic bearings withstand heat in the 40C / 104F range and a small airflow from the turbine cools the bearings. Most spindles have a limited duty rating which requires them to be shut down or turned off over time. All the advantage of nominal high speed is lost when the spindle overheats and is switched off - in addition to having a person watch the CNC machine. Air Turbine Tools® can run lights out.
Low friction and low heat with the positive air pressure through the spindle resolves accuracy problems resulting from thermal expansion and increases durability.
No maintenance or oil lubrication. Spindle and motor maintenance, part cleaning and lubrication of motors are time consuming and costly.
With plastics, graphite, wood - oil free Air Turbine Spindles® and Air Turbine Motors® also eliminate lubrication, oil mist contamination and chemical interactions.
Tool life improved. Coatings work well at high temperature which requires high speed. Super finish quality with no secondary cleaning required.
