About Hautau
Over 45 years of service to the tube processing industry.
1972
We designed and patented our first rotating-head tube cutoff machines for trimming automotive glass-pack mufflers, and the prototype cutoffs were proven in a continuous production line by a major exhaust manufacturer. Wheel-type cutoff tooling was used and cycle times were as low as 4.5 seconds including transfer.
1993
Our RC Series of rotary-head tube cutoff machines were introduced, featuring full servo control of cutting and feeding motions and integrated PLC control of all machine functions.
Our SC30 dual-blade tube shear was re-designed to work with our indexing tube loader for round and shaped tubes.
1995
1998
Our tube cutoff lathes are now available with an auxiliary chuck slide that allows full chamfering of both tube ends. This a major advancement that eliminates secondary operations. All OD and ID edges are beveled or chamfered and finished parts are produced.
1999
Our RC-CCX dial-transfer machines are developed for tube cutting and double-end finishing at rates up to ten pieces per minute. Typical systems included a tube bundle loader and rotating-head cutoff, plus precision ID boring, tube forming, part marking and powered runout systems.
Fully automated pin-stamping is integrated into the tube handling system for 100% process tracking.
2001
New CCX double-end tube boring machines were commissioned for high-speed boring and profiling of heavy conveyor idlers and rollers. When coupled with our RC tube cutoff lathe, customers realized cycle times as low as 15 seconds for an 8 inch diameter x 90 inch part.
2003
Our production increases to 18 tube cutoff machines per year, so we moved operations to a larger manufacturing facility in Brookville, Indiana.
2004
Custom Servo Runout systems are added for sorting different cut lengths. When cutting multiple lengths, the tubes are automatically separated and transferred to carts or bins.
2007
Full integration of Robotic Unloading and Packaging. Options include vision part inspection, slip sheet insertion and pallet transfer conveyor.
