High Speed Air Spindles

	Presenting the 30,000 RPM Mini-MacTM series spindles for your lathes and mills. Perfect for micro machining or eliminating secondary operations! Small and easy to mount in virtually any machine!

	Presenting the 30,000 RPM ATC-Mac? series spindles. Now your CNC mill or machining center can have high-speed spindles that are loaded and unloaded unattended through the machines tool changer.

Affordable High Speed Machining - Our high speed air driven spindles operate on "shop air". They rotate at approximately 30,000 RPM. Most lathes and mills turn to slowly to efficiently drill or mill small holes or slots. Our high speed spindles let you mill and drill at more advantageous speeds and feeds. Additionally, our speed gives you the versatility to grind or polish so you can achieve close tolerances and and smooth finishes. Numerous secondary operations can often be accomplished on the machine by adding the air spindle. Even older equipment can have "live tooling"! Reduced production time and better finishes! The Mini-MacTM, though small in size, is a precision tool. Each air driven spindle is held to exacting tolerances. The result is a high speed tool that is accurate and consistent.

When 30K Is Not 'High Speed"
With small tools, the speed that can be achieved with an add-on air-powered spindle may be needed just to use the tools effectively.
Air-Powered High Speed Spindle
Two different designs for this spindle allow it to be mounted on a lathe's turret or slide (like an add-on live-tool spindle) or mounted in a machining center's toolholder. In either case, the spindle is capable of 30,000 rpm. When driven by an 80-psig shop air supply, the spindle can deliver 75 W of cutting power.
