Wire machines New technology for ALC wire cut EDM range
The new ALC i Groove edition is a range of innovative technology that will be standard for Sodick ALC400 and ALC600 category wire machines.
All models in the ALC400 and ALC600 range will be equipped with Sodick’s new, patented wire rotation mechanism, together with significantly improved Stepcut technology and a number of increased automation facilities, as well as larger dielectric tanks. This newly developed technology, patented by Sodick, rotates the wire during the skim cut operation, so that workpieces are machined from top to bottom with the “unconsumed” surface of the wire.
Conventionally, wire electrodes are controlled solely by tension and running speed, while being constrained by a die. The company’s i Groove rotation mechanism provides additional control over the wire, resulting in increased surface quality and improved geometric accuracy, whilst at the same time minimising wire consumption – combining the best ecological solution with the highest quality of EDM machining.
The i Groove technology incorporates the manufacturer’s new step machining functions, developed to easily and conveniently overcome issues such as the typical “streaky” precision errors that can occur where the plate thickness changes suddenly, for example at a counterbore or a hole. Sample workpieces machined by Sodick using the i Groove technology have shown that the streak shaped precision error can be reduced by up to 50 percent when compared to conventional machining.
To support the new facilities, the machining technology database has been expanded to include an even greater range of materials. In addition, i Groove enables users to select optimum conditions visually by using on-screen icons, while the mesh FTC function enables high precision groove and step machining even for multi-cavity finish.
The AL i Groove edition machines feature a number of advanced technologies to assist in increased automation including, of course, the use of Sodick’s linear motor. Furthermore, the machines incorporate the FJ-AWT high-speed automatic wiring device with its sophisticated automatic recovery performance in the event of disconnection.
Enhanced management functions include digital machining fluid monitoring (filter pressure, fluid level specific resistance, fluid temperature) as well as TH COM — which minimises the effect of temperature changes within the machine, reducing the amount of thermal displacement by 50 percent compared to a conventional machine. Another function, AIM (AI Maintenance), monitors and automatically diagnoses the status of the machine, including operation, maintenance and installation environment, boosting the machine’s operation rate, reducing machining defect rates and improving traceability.
Additional automation and labour-saving options have been added to the line up including Sodick’s S3 Core automatic core processing device which keeps the workpiece from dropping after removal from machine and automatically retrieves it, together with camera-type on-board measurement systems and enhanced compatibility with robotic automation.
In addition to all these technical features, i Groove edition machines also feature newly designed, larger capacity dielectric tanks (the ALC400G tank is increased from 675 litres to over 790 litres, and the ALC600G tank is increased from 850 litres to greater than 990 litres), with three dielectric chambers, which has resulted in a slightly increased machine footprint. Furthermore, the number of filters has increased from three to four in order to further increase filtration efficiency.
