Confirming its position as developer and manufacturer of the world’s most advanced EDM systems, Sodick demonstrated its latest technologies at EMO this year. Machines on the stand included no less than four wire EDM machines; with two brand-new models, the ALC800G and VL600QH, as well as a Premium ALC600L, while Sodick’s extensive die-sinker EDM range was represented by an automation-ready AG60L equipped with a robot, as well as one of its highly successful entry-level AD55L machines. In addition, the company showcased its unique, ground-breaking 3D metal additive manufacturing machine, with integral milling capability – the OPM250L, which continues to draw crowds wherever it appears.
ALC800G and VL600QH – New Wire Machines with extended Z stroke
The newly announced ALC800G, incorporates all the features and benefits of Sodick’s Premium wire range, as well as offering a three-sided automatic opening door and generous work tank with inner dimensions of 1500mm (X) by 1040mm (Y). The high-column option version of the machine also provides an extended Z-stoke of 800mm.
Meanwhile, the new VL600QH, which incorporates an extended Z-stroke of 500mm – making it suitable for tackling even taller work-pieces, is a development of the VL600Q linear motor driven wire-cut EDM, which has proved to be extremely successful since its debut at EMO Milan in 2015. The new machine retains all the features and benefits of the earlier model, including the FJ-type Automatic Wire Threader with “pop-up” function to enable reliable automatic wire threading.
ALC600G Premium Wire Machine
The ALC600G wire EDM machine incorporates all the company’s latest digital innovations, resulting in a machine capable of increased cutting speed, greater accuracy and improved surface finish. These achievements are the result of Sodick’s many years’ experience in developing linear motor technology, including the incorporation in the ALC600G of the Smart Pulse Generator, which dramatically reduces the number of cuts necessary to achieve the required accuracy and surface finish, when compared to conventional machines.
AG60L Die-sink with Robot
The best-selling AG60L, which incorporates Sodick’s linear EDM technology, has been installed on shop-floors and in tool-rooms around the world in sectors including automotive, aerospace, medical and pharmaceutical. The three-sided automatic rise and fall work-tank makes the machine ideally suited for automation, hence its appearance at EMO with a robot.
AD55L Entry-Level Die-sinker
Making world-leading EDM technology available to entry-level participants, the AD55L incorporates a plethora of leading Sodick innovations, including linear motors on X, Y, and Z axes, as well as the K-SMC Sodick Motion controller, 1Gbit/sec communication technology, SGF nano-wear generator and ceramic work-zone, ensuring a superior level of performance compared to other entry-level EDM machines. In addition, the symmetrical structure of the AD55L has been specifically designed to provide improved rigidity in order to maximise machine performance.
OPM250L Combined 3D Additive Manufacturing/Milling Centre
Sodick’s unique metal 3D additive manufacturing machine with integral linear motor drive milling centre represents the industry’s first one-step solution for the entire metal 3D additive manufacturing process. The OPM250L is ideally suited for applications in sectors including aerospace, automotive, defence and pharmaceutical. Recent developments include the new “function parallel” mode, which enables simultaneous laser sintering of multiple locations by controlling a single laser at high speed.
Simply put, the OPM250L operates as follows: first, a metal powder is uniformly spread and then melted and solidified by scanning with a laser beam (this process can be repeated up to ten times) after which the surface is subjected to high speed milling process, creating the high quality, accuracy, precision and finish which are not achievable with a laser process alone, after which the metal powder is uniformly coated again and the process is repeated, until the geometry is complete.
In addition, the combination of a linear motor drive system with the machine’s gantry structure ensures excellent positioning and machining accuracy by taking full advantage of backlash-free, rapid axis movement while minimizing any deformation of the machine structure, while the dielectric chiller and surface level adjustment function ensure stable machining performance right from the very start.
