Available from Absolute Machine Tools, the Accutex DS-550CM die sinker EDM will be on display as part of an automated cell also including a Tongtai TMV-510G machining center and tended by a FANUC M-20iA robot arm. The cell will perform electrode management, robotic part handling and advanced control intelligence in addition to production machining, according to the company.
The EDM features an XYZ working capacity of 20" × 16" × 14" (500 × 400 × 355 mm) with a worktable size of 32" × 18" (813 × 457 mm). The machine accommodates workpieces as large as 47" × 27" × 17" (1,194 × 686 × 432 mm) and as heavy as 2,970 lbs (1,345 kg). The EDM is designed with finite element analysis (FEA) to improve rigidity and resist distortion with heavy workpieces. Contributing to its rigidity and accuracy is a heavily ribbed Meehanite casting. Other components include a precise drive system; linear bearings; class 5, pretensioned, fine-finish ballscrews; and high-resolution servo motors, along with roller-type linear guideways and optical scales. For added flexibility, options include a built-in C axis with 360-degree indexing, an automatic electrode changer, dielectric cooler and custom tooling package.
The EDM’s full-color, 15" LCD monitor eases reading, and the software provides dialogue options for straightforward programming and operation. With it, the user can perform three-axis machining in multi-cavity, circular, internal/external spherical, 45-degree corner machining and square and any angle orbital directions. The EDM also supports three-axis linear and two-axis arc machining, as well as offering electrode compensation for helical machining.
