Press Release Summary:
To hog cast iron and aluminum on same machine, CNC Jaguar(TM) horizontal machining center (HMC), with optional spindle, performs both high-speed and high-torque cutting without changing spindles. HMC utilizes 50% of spindle torque when cutting 6061-T6 aluminum with 2 mm depth-of-cut at 8000 rpm and 15840 mm/min feed. Conversely, it can cut cast iron at 463 rpm and 940 mm/min feed rate with 5 mm depth-of-cut and requires less than 80% of torque.

Lamb Technicon Announces New High-Torque / High-Speed Spindle
For hogging cast iron and aluminum on the same CNC
Chicago, Ill, Sept. 4, 2002 - Lamb Technicon (Warren, MI), a UNOVA Company, has announced the development of a new high-torque / high-speed spindle which allows for both high speed and high torque cutting on the same CNC machine without changing spindles.
The spindle, which is an option on Lamb's Jaguar(TM) horizontal machining center, has been designed to offer high-speed cutting in aluminum and other non-ferrous metals, and yet can handle heavy depths-of-cut in cast iron at lower speeds without exceeding the torque capability. In one example of high-speed machining, 50% of spindle torque is utilized when cutting 6061-T6 aluminum with a 2 mm depth-of-cut at 8,000 rpm and 15,840 mm/min feed. Conversely, cutting cast iron using the same spindle at 463 rpm and 940 mm/min feed rate with a 5 mm depth-of-cut required less than 80% of torque.
The new spindle provides greater torque than comparably sized direct-drive spindles, enabling heavy metal removal and high depths of cut, even at low spindle speeds. Benefits of the new spindle include reduced capital investment, as one machine can now do the job that was previously done by two. Also, productivity increases as time-consuming mechanical changeover of spindles is eliminated.
Lamb's Jaguar machine is the stiffest HMC on the market, making it perfect for high-torque applications. But its 1-g acceleration and 45m/min traverse rates also make it applicable to high-speed applications.
For more information, visit booth A-8101 where there is an exhibit featuring the new spindle, and Lamb Technicon personnel are available to discuss this product in detail.
