Large diameter tubes need large rolls for highest quality production

a process with final homogeneous distribution of regular carbides, which maximises wear resistance and avoids cracking and breakages. Dedicated procedures of stress relieving, high temperature hardening, and tempering (at least three cycles), accompanied by inspection of the residual austenite, allow the best working conditions, even in severe applications. Atomat also pays particular attention to the surface of the keyways, which can be subject to micro cracks. The cut surface is treated with sandblasting, polishing or dedicated stress relieving to avoid this.

OWNERS of the Powermax45 air plasma system can now upgrade to a Duramax series torch – the same type found on Powermax65, 85 and 105 systems. Replacing the T45 torch originally sold with the Powermax45 will provide longer consumable life, better cut quality, and more torch and consumable options. Designed for durability and reliability, Duramax torches include Spring Start™ technology in the electrode to eliminate moving parts and ensure consistent, reliable starting. Hypertherm offers its Duramax torch in seven different styles. Owners can choose from 15° hand, mini machine and robotic torches in addition to the traditional hand and machine torch options with lead lengths up to 15.2m (50 ft). The switch to Duramax torches also gives Powermax45 owners access to Hypertherm consumable technologies such as CopperPlus ® , Max control and needs: dimensions, quality, availability, etc. Steel comes from forged steel flanges, with re-forged material used to obtain dimensions out of stock with enhanced quality and mechanical properties, or from forged bars. After the melting process, flanges and bars are annealed and inspected with an ultrasonic system. Chemical composition and reduction ratio during the forging process are certified. Material must present a fine and homogeneous distribution of carbides, without segregations that have a detrimental effect in breakage resistance. For these high alloyed steels, heat treatment is also important. The procedure is tailored in consideration of roll shape and dimensions. Qualified heat treatment suppliers can grant

ATOMAT states that its production has always been committed to guarantee the quality levels within all the products in its range: CNC machinery and rolls for tube and wire. This approach is now leading the organisation in enlarging the production range of steel tooling up to 24" OD tubes. Recently commissioned equipment grants Atomat the ability to machine rolls suitable for the above tube diameters. Along with working capacity, Atomat has improved and developed an operational context with a group of selected and highly qualified partners that ensure levels of quality concerning raw material and heat treatment. The company considers this essential to comply with the expectations of the most demanding customers. Raw material is selected in consideration of different characteristics

New torch options for plasma system owners

gouging, FineCut ® , HyAccess™ and FlushCut™. “Powermax45 customers have been asking us about the ability to use Duramax torches with their system for a long time, since it gives them access to so many more cutting and gouging options,” said Jonathan Murphy, a Hypertherm marketing specialist. “With tens of thousands of these in use every day, we wanted to do what we could to help owners take advantage of the newest technology.” Hypertherm designs and manufactures industrial cutting systems and software for use in a variety of industries such as shipbuilding, manufacturing and automotive repair. Its product line includes cutting systems, in addition to CNC motion and height controls, CAM nesting software, robotic software and consumables.
