As a result of double four- spindle machining, two finished parts are produced by the machine per drum rotation. In double rear end machining, there are eight spindle positions available for front machining the workpiece and two spindle positions for rear-end machining, and they all work simultaneously. Further productivity increases can be achieved with optionally available additional slides in positions seven and eight in the part-off position. "is feature allows the user to implement both an additional rear-end machining operation as well as simultaneous pre-part-off of a follow- up workpiece during rear-side workpiece machining," Mr. Rupp says. Machining Units e basic construction of the AC10-36 follows the classical concept of the cam-controlled automatic, where eight spindles index in a precision-made spindle drum that is locked with repeatability by a robust Hirth coupling. e cross-slides for OD machining permit machining in the X, Z and Y axis on positions one through eight. e X-axis slide moves radially to the spindle centerline on linear guide- ways. e Z-axis motion uses a hydrostatic quill design that travels parallel to the spindle centerline and passes through the X-axis carrier at 90 degrees. Both axes are driven electro- mechanically. Using interpolation, these allow X-Z contour motion at all eight stations. e modular cross slide tool turrets can bring one or more tools into the cut at any of the eight stations, poten- tially multiplying the number of tools that can be used at any given station. is flexibility allows for multiple operations to be performed at a single station or gives the option of having redundant tools in place for unattended operation. Each and every cross-slide can provide Y-axis machining capability as well. In addition to its linear motion, the Z axis can be arranged to swivel. is motion allows a second or third tool or more tools to be positioned on the workpiece. It also allows for Y-axis milling by interpolation between the linear X axis and the rotary C axis. e Hirth coupling is used to accept variously config- ured turrets that carry cutting tools used for a given station. As on the SCX series, the ACX standard turrets include devices for (off-center) drilling, deep-hole drilling, thread cutting, angular drilling, cross drilling, contour milling, gear hobbing and multi-edge turning, spherical and polygon turning (cross) as well as cross-slides (endworking) for driven and stationary tools. Essentially important: all units can be used independently from one another in every spindle position. e standard connection allows any turret to be positioned on any cross-slide. is modular design is suitable for both stationary and driven tools. For driven tools, an integral motor is mounted in the Z-axis quill and generates 8,500 rpm. Coolant lines are also routed through the quill, keeping the workzone clear. rough-the-tool coolant up to 100 bar is available. e cross- and longitudinal-slide turrets use HSK or Capto cutting :: Here are three combinations of the eight-spindle concept using the machine's main and counterspindles.
