EDM Model Promotes Accuracy, Repeatability
IMTS 2018: AccuteX’s AL-600SA CNC Wire EDM moving-table model, displayed in Absolute Machine Tools’ booth, has six-axis processing capability, a PCD cutting circuit and linear shaft motors that contribute to improved positioning and speed.
AccuteX’s AL-600SA CNC wire EDM moving-table model will be displayed in the Absolute Machine Tools booth. It has six-axis processing capability, a PCD cutting circuit and linear-shaft motors that contribute to improved positioning and speed. The machine features Hiwin linear guideways, 0.000004" Fagor glass scales and 64-bit processing.
Other features include S-cut fine-finish skimming (9 µin Ra surface finish) and lead-in/lead-out control that reduces witness marks at entry and exit points. The machine is accurate to ±0.00012" (0.003 mm) and repeatable to ±0.00008" (0.002 mm). MST-II micro sparking technology promotes surface finishes as smooth as 5 µin Ra in five passes.
The machine features the company’s fully annealing automatic wire threading and can perform submerged machining as deep as 11.81" (300 mm). Travels measure 23.62" in the X axis, 15.74" in the Y axis, 11.81" in the Z axis and 3.94" in the U and V axes. Maximum workpiece size is 38.97" × 24.41" × 11.61" (990 x 621 x 295 mm), with a maximum workpiece weight of 2,450 lbs (1,113 kg).
Cutting metal with an energized strand of wire is still one of the most dynamic frontiers in metalworking, and this shop goes to extremes to keep up with the latest advances. It has even developed some of its own.
Hummingbird takes on machining work that is too small for most shops to handle. In fact, Hummingbird tries not to handle it either. To accurately machine the tiniest parts, this shop relies on processes that are as hands-off as possible.
Electrical discharge machines, both wire and ram type, have undergone rapid improvements in capability, economical operation, speed and flexibility. New applications are continually emerging as shops discover the advantages of this process.
