CNC International brings new EDM machines to MACH 2016

At MACH 2014, CNC International made its MACH debut. An exhibition that also noted the UK show debut of the Accutex line of wire cut EDM machines, something that proved a resounding success. Generating considerable sales at the last event, CNC International gave a UK show debut to the Accutex AL600 CNC wire EDM at MACH 2016 to emulate the results of the previous show. This impressive Accutex machine appeared alongside the industry leading Exeron range of high speed machining centers and spark erosion technology.

Since their UK introduction at MACH 2014, it is no surprise the Accutex Series of Wire Cut EDM machines has proven such a hit. With a linear shaft motor drive and a closed loop control to eradicate backlash, the machines deliver a high level of repeatability with low friction and exemplary efficiency and precision levels. At MACH 2016, the new AL Series that has five machines in the range from the smallest AL400SA to the largest AL750, was represented at MACH by the AL600. The smallest machine can accommodate workpieces up to 790 by 610 by 215mm (LxWxH) whilst the large AL750 can accept workpieces up to 1190 by 720 by 295mm (LxWxH).

The AL600SA, shown at MACH 2016, has a maximum workpiece weight of 550kg, an X, Y and Z stroke of 600mm by 400mm by 300mm and a UV stroke of 100 by 100mm. The AL600 has a maximum water level in the tank of 300mm and a water system capacity of 900 liters. Build quality and rigidity is assured by the 3,700kg machine weight that is packed into the compact 2480mm by 2980mm by 2210mm footprint.

The AL600SA incorporates a rapid servo response unit that can enhance the sensitivity of the discharge gap control to improve production times by upwards of 10%. Furthermore, this rapid servo response unit prevents the wire from breaking to reduce downtime whilst also increasing the processing speed. In addition, the Accutex AL600 Series to be shown at MACH has a high resolution signal processor that delivers a smoother velocity control than alternate machines. The result is improved stability of positional control to guarantee unrivalled contouring accuracy with a resolution narrowed down to 0.2microns.

Working in conjunction with this is the Accutex Corner Pro system that optimises data such as wire thickness, cutting data, angle and workpiece thickness. This feature automatically controls the machine parameters to achieve the best possible cutting performance. What this means, is that small and continuous corners can be processed with astounding precision. This corner precision is matched by Accutex passion for perfection that now sees the AL Series introduce its new Lead-In and Lead-out technology. This innovation reduces the commonly occurring wire-mark at the lead-in process.

Adding to all this, CNC International can supply the Accutex line with a host of optional extras that include auto wire threading, anti-collision on Z-axis, safety door interlock, transformer, remote master, auto voltage stabiliser, alarm messenger, pilot lamp, 45kg jumbo wire feeder and high pressure water jet threading. The exceptional Accutex line was accompanied at MACH by the high-end line of Exeron HSM machining centers and spark erosion machines.
