AIR TURBINE TECHNOLOGY INC. is offering the new Air Turbine Spindles® 601 Series spindle that combines constant high-speed in cut, energy efficiency and a user-friendly design. As a result of its governed high-speed performance the 601 Series is a valuable addition in any CNC magazine to accelerate productivity and reduce costs in today's fast-paced industrial landscape.
The compact 601 Series spindle incorporates Air Turbine Technology Inc.’s patented governor technology, which increases CFM airflow on demand to maintain constant speeds of 40,000 to 90,000 RPM under cutting load on the toolpath through the program. The 601 Series spindle provides up to 0.2 HP (0.15 kW) power, delivering ample power for micro-machining applications - although Air Turbine Technology Inc.’s range includes spindles with power to 1.4HP (1kW) for larger tools and hard materials.
This governed turbine maintains the required surface feet per minute (SFM) and chip load for micro and small tools by sustaining high RPM on the toolpath.
Cycle times are routinely reduced six to 10x compared to standard CNC spindles at 6,000 RPM, to at most 20,000 RPM. Maintaining high-speed in cut also optimizes tool performance, eliminating tool breakage and ensures the production of standardized high-quality parts.
Air Turbine Technology Inc.’s direct drive 601 spindle generates no heat, consistently delivering 2-micron accuracy with no thermal growth in the spindle. No maintenance is needed and just 2 moving parts makes this high-speed spindle reliable.
A connection to 90 psi (6.2 bar) air is all that required to make any CNC a high-speed machine. Fully automated loading is available using air supply through the machine spindle, a collar and stop block or manual connection through the side air inlet. Easy installation minimizes downtime, allowing manufacturers to quickly adapt to changing production demands.
The high-speed capabilities of the 601 Air Turbine Spindle® streamline production by the elimination of secondary operations. Moreover, micro tools are expensive. Big savings result from optimization of small tool performance and life. Governed high-speed also enhances the overall surface quality of the finished products.
The 50-mm extended barrel on the 601 Series reaches into tight workpiece operations allowing greater maneuverability and access to pockets, angles and hard-to-reach areas. These dimensions enhance access and tool performance on all machines, including those with limited Z-Axis travel as well as 360˚ five-axis programming. Another great advantage is that the 601 design eliminates the need for long cutting tool stick-out from the spindle collet in angles or pockets causing vibration, tool breakage and poor surface quality.
Air Turbine Spindles® generate no heat, ensuring consistent accuracy during extended use. Operation with no heat also eliminates the need for a duty cycle, allowing continuous 24/7 operation without requiring cool-down periods. No lubrication is required in this high-speed turbine - eliminating contamination of parts from misting. This feature is especially important to the medical and food industries. Oil-free operation also reduces maintenance and lubrication costs.
Most popular taper options are available, including HSK-A63, CAT40, BT40, BT30, DIN30, DIN40, and 20-mm JS straight shank enabling flexible use with any spindle taper.
