STUDER S33 With flexLoad Automation Grinds Complex Test Specimens

MIAMISBURG, Ohio, October 27, 2020 – The STUDER S33 CNC universal cylindrical grinding machine handles individual, small-batch, and large-scale production of short to long workpieces. It grinds complex workpiece geometries in a single clamping and provides excellent results on essential test specimens for the aerospace and defense industries. Paired with an integrated flexLoad loader and robot, the versatile S33 provides a fully flexible solution with easy programming and reduced setup times.

The STUDER S33 changes over from grinding between centers to live spindle grinding in less than two minutes. With distances between centers of 15.7" (400 mm), 25.6" (650 mm), 40" (1,000 mm) and 63" (1,600 mm), and a center height of 6.9" (175 mm), the STUDER S33 can machine workpieces with a maximum weight of 330 lbs (150 kg). A solid Granitan® S103 machine base provides stability and well-damped vibration for excellent surface finishes.

To perform straight and angular plunge grinding on one machine, the wheelhead swivels to positions of 0, 15 and 30 degrees, and can be equipped with a spindle motor for external grinding, as well as a high-frequency spindle for internal grinding in different configurations. The STUDER S33's B-axis design features an automatic 1-degree Hirth coupling with a swivel range of -30 degrees to +210 degrees to accept up to two outer diameter (OD) grinding wheels and one inner diameter (ID) grinding spindle for complex tasks. Options include a chuck workhead for chuck applications and a C axis for thread and form grinding.

With graphical StuderPictogramming and a software design that expands with integrated modules, the STUDER S33 offers easy programming. Optional StuderWIN software allows shops to program grinding and dressing cycles on an external PC.

The optional flexLoad loader with FANUC LR-Mate robot for the STUDER S33 provides a fully flexible automation solution, with a large side door for easy access and a stacking method that expands through optional pallet stackers or conveyors. The flexLoad system also accepts options that include gauging, barcode scanning and a coolant-clearing air nozzle. To maintain safety, flexLoad's full-system sheet metal enclosure requires the operator's explicit permission to open its main access door and three parts drawers. A side flanged panel connects flexLoad to the S33, further enhancing safety and reducing overall cycle time by up to eight seconds over an automatic door.
