AccuteX’s new AL-600SA CNC Wire EDM is from Absolute Machine Tools. The AL-600SA moving-table model can be fully equipped with 6-axis capability, PCD cutting circuit, and AccuteX’s exclusive linear shaft motors that provide a 10-year positioning guarantee. These motors were designed and built fully in-house specifically for AccuteX wire EDMs. This concept ensures enhanced precision and performance with its maintenance-free design, 10 percent faster cutting, HIWIN linear guideways, 0.000004” Fagor glass scales and 64 bit processing.
S-cut fine finish skimming (9 Ra µin. surface finish), enhanced lead in/lead out control that eliminates witness marks at entry and exit points. Accuracy is achieved at +/-0.00012" (0.003 mm) and repeatability +/-0.00008" (0.002 mm). MST-II Micro Sparking Technology comes standard for surface finishes down to 5 Ra µin. in five passes.
The AL-600SAi comes standard with AccuteX’s patented fully annealing automatic wire threading (AWT) with the ability to perform submerged machining up to 11.81" (300mm) deep. Travels are 23.62” X-axis, 15.74” Y-axis, 11.81” Z-axis, and 3.94” U & V axes. Maximum workpiece size (XYZ) is 38.97” z 24.41” x 11.61” (990 mm x 621 mm x 295 mm) with a maximum workpiece weight of 2,450 lbs. (1,113 kg).

Softening a metal by heating it to and holding it at a controlled temperature, then cooling it at a controlled rate. Also performed to produce simultaneously desired changes in other properties or in the microstructure. The purposes of such changes include improvement of machinability, facilitation of cold work, improvement of mechanical or electrical properties and increase in stability of dimensions. Types of annealing include blue, black, box, bright, full, intermediate, isothermal, quench and recrystallization.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- electrical-discharge machining ( EDM)
electrical-discharge machining ( EDM)
Process that vaporizes conductive materials by controlled application of pulsed electrical current that flows between a workpiece and electrode (tool) in a dielectric fluid. Permits machining shapes to tight accuracies without the internal stresses conventional machining often generates. Useful in diemaking.
- polycrystalline diamond ( PCD)
polycrystalline diamond ( PCD)
Cutting tool material consisting of natural or synthetic diamond crystals bonded together under high pressure at elevated temperatures. PCD is available as a tip brazed to a carbide insert carrier. Used for machining nonferrous alloys and nonmetallic materials at high cutting speeds.
Process of both external (e.g., thread milling) and internal (e.g., tapping, thread milling) cutting, turning and rolling of threads into particular material. Standardized specifications are available to determine the desired results of the threading process. Numerous thread-series designations are written for specific applications. Threading often is performed on a lathe. Specifications such as thread height are critical in determining the strength of the threads. The material used is taken into consideration in determining the expected results of any particular application for that threaded piece. In external threading, a calculated depth is required as well as a particular angle to the cut. To perform internal threading, the exact diameter to bore the hole is critical before threading. The threads are distinguished from one another by the amount of tolerance and/or allowance that is specified. See turning.
- wire EDM
Process similar to ram electrical-discharge machining except a small-diameter copper or brass wire is used as a traveling electrode. Usually used in conjunction with a CNC and only works when a part is to be cut completely through. A common analogy is wire electrical-discharge machining is like an ultraprecise, electrical, contour-sawing operation.
