AIR TURBINE TECHNOLOGY INC. offers its ‘all rounder’ 625 Series spindles for manufacturers seeking precision, reliability, and higher productivity. Governed constant high speeds under load from 30,000 to 65,000 RPM with power ratings up to 0.55 HP are easily added to any CNC with the 625 Series spindle and are ideal for engraving, moldmaking, milling, and finishing with small tools up to 1/8-in. (3-mm) capacity.

Using a patented direct-drive design with only two moving parts and optimized air circulation over bearings, these spindles operate 24/7 with no heat or thermal expansion and eliminate duty cycle limitations.

By increasing air flow volume to match cutting load, Air Turbine Technology’s governor-controlled turbine maintains constant rated speeds and torque under load, allowing users to cut faster and cleaner while extending tool life and ending frequent breakages of small tools. The performance of the 625 Series spindle is thus distinguished for its ability to accelerate cycle times and minimize tool breakage, while maintaining exceptional accuracy at 2 micron TIR and vibration at just 0.4 mm/s. This is completely different from nominal high speed coolant spindles that fade in cut and clog up with chips.

All that is required is a connection to 90 PSI compressed air. Full ATC is available on any CNC with air through the spindle or using the patented Air Turbine Technology collar and block.

By avoiding gears, vanes, and brushes, the spindle’s design reduces friction and wear as well as eliminates heat. This reliable turbine direct drive dramatically reduces downtime as well as repair costs from friction and overheating. Supported by a range of toolholder configurations including JS, HSK, CAT, BT and DIN, the 625 Series spindle can be seamlessly integrated into any CNC machine magazine for automated, uninterrupted production.

The extra power 625X Series spindle further boosts performance on any CNC with its patented double turbine delivering speeds up to 50,000 RPM and power of 0.76 HP. This makes the 625X Series spindle effective in demanding operations with larger tools or operations such as contouring and peck drilling in hard materials with tools up to 1/4 in. (6 mm) capacity.

Both 625 Series spindles provide practical benefits, power to maintain high speed, no duty cycle, continuous operation, predictable precision and versatile mounting options, enabling manufacturers to achieve superior surface finishes, reduce cycle times and maintain quality across a wide range of machining tasks.
