Automated loading and parts handling system complement state-of-the-industry laser and machine control technology
Han-Kwang USA announces immediate availability of its new Model TL 6015, a tube cutting laser system capable of handling 24’ long, 6.5” diameter workpieces up to 1/4” wall thickness in mild steel and 0.200” in stainless steel. Equipped with a powerful 2.5KW Panasonic laser and a versatile Siemens 840D CNC to control all functions of the machine, the TL 6015 can significantly increase the tube production in any department or shop, especially when used with Han-Kwang’s proprietary “Flex 3D” tube cutting software . The unit comprises an automatic bundle loading system with tube V-support, auto-centering rotary chucking system, laser cutting station and automatic parts removal station.
Maximum positioning speed on this new laser system is 4700 ipm for the X-
axis and 120 rpm for the rotary A-axis. Max acceleration rate is 1G, while the laser beam is precisely controlled by the unique Han-Kwang Auto Focus Control (AFC). This AFC technology allows the machine to automatically adjust the focal length of the cutting lens to accommodate variations in the materials being processed or changes in material feed, which eliminates the downtime normally associated with manual adjustments.
A new generation of sensing board in the S5 laser cutting head on the TL 6015 translates into faster cutting speeds on round, square or rectangular shapes.
In a recent design modification, the entire loading section of the machine has been enclosed, as depicted in the attached illustration.

Improves efficiency and bearing reliability on industrial compressors and other applications; positive locking WITHOUT washers and keys; supports extreme thrust loads
Advanced Machine & Engineering Co., (AME) Rockford, IL provides its unique Spieth locknuts for accurate rotor positioning and reliable thrust bearing retentionon compressors, shafts, spindles and other industrial/commercial applications, in a unique engineering achievement.
In a compressor application, for example, the locknut can play a key role in establishing the clearance between the rotor and the compressor housing, where too little clearance causes seizure, while too much reduces compressor efficiency, due to leakage around the rotor body.
While the standard Spieth locknut configuration had considerable appeal for the application, several design refinements were deemed highly beneficial for this application. “We liked the positive locking feature without washers and keys, plus the locknut’s ability to support extreme thrust loads by providing full 360º contact around the thread flanks,” according to one application engineer contacted for this story.
Key features that led to one compressor manufacturer’s selection of the Spieth product from AME included:
The full circumference contact of the Spieth locknut was designed to ensure the locknut would not back off, even when subjected to extreme shock loads. It further aligns its contact face with either a zero runout or, as needed, it can be adjusted to suit the inaccuracies of the in-line connecting components, thus compensating for minor errors of parallelism due to the stack-up of mating parts. Uneven bearing loading is thus compensated and its impact minimized.
The basic design of the Spieth adjustable locknut involves two axially arranged radial grooves, one from the outside and one from the inside, which result in a diaphragm-like cross-section to give the locknut a predetermined axial elasticity. The internal groove divides the locknut into a clamping and a locking section. Depending on the nut size, multiple axially arranged socket head set screws are used to clamp the sections together. This eliminates the thread flank clearance between the rotor and the locknut, allowing for shockproof clamping.
In installing the locknuts, a consistent tool torque setting was found sufficient to achieve parallel locknut body and threads. Thus, the face of the thread flank and centerline of the shaft were always in ideal alignment. This was done to provide a square thrust collar for thrust bearing reliability and rotor positioning.
Other applications for Spieth locknuts typically include shaft and spindle retention on bearings, where displacement, axial preload and clearance issues are critical. The unique design of this locknut ensures no back-off, even when subjected to extreme shock loads. In machine tool and heavy equipment use, for example, spindle runout due to uneven bearing loads can be eliminated, due to the full 360º contact around thread flanks. Spieth heavy-duty locknuts can be used with needle and roller thrust bearings, plain thrust bearings or taper roller bearings on ballscrews, worm drives, bevel gears and other high-thrust carrying components.
