United Grinding North America, Inc. offers its STUDER S33 universal cylindrical grinding machine featuring an all-new ergonomic design and a new post-process control system that checks the absolute diameter and length of the workpiece while it is on the machine.
This versatile machine can perform I.D., O.D. and thread grinding operations on medium-sized workpieces in individual batch production. The S33 has a center height of 6.9" (175 mm) and distance between centers of 25.6" (650 mm) or 39.4" (1,000 mm), with a maximum workpiece weight between centers being 176 lbs. (80 kg) or 264 lbs. (120 kg).
To increase the ergonomics and convenience of its products, STUDER applied a new design to the S33 that makes it easier for operators to interact with the machine, including better access to the work area, easier loading and unloading of parts as well as improved access for automation. Furthermore, the machine's main contours are rounded for a sleek new look.
Only available on the S33, STUDER's new post-process multiControl system is an alternative for external control measurement using manual micrometer screws. The system provides absolute measurement of workpiece diameters without having to remove the part from the clamping source for remeasurement. Automatic size adjustments are done based on measuring each part after grinding. The system records the measuring data in a PDF or Excel file, allowing users to determine part rejection causes during unmanned night shifts. Overall, multiControl is a cost-effective process monitoring system that checks the differences and actual values of a workpiece, allowing users to base programming on absolute masses from drawings.
STUDER offers two wheelhead variants for the S33. A new turret wheelhead with two motor spindles and an internal grinding attachment enables the processing of complex geometries in a single clamping. Also available is a wheelhead for external grinding at 0° to 30° in production applications or two internal grinding spindles with one external spindle.
A universal workhead design allows the S33 to perform either live spindle grinding or grinding between centers, with users, in some cases, being able to retool the machine from one process to the other in less than two minutes. The S33 can also be fitted with a chuck workhead for chuck applications, while an optional C-axis allows the machine to perform thread and form grinding.
"A Granitan S103 mineral-casting machine base allows the S33 to achieve excellent vibration damping and thermal stability that results in high surface quality and workpiece accuracy," said a company spokesperson. "Adding to the machine's rigidity are longitudinal and cross slides made from high quality gray cast iron and optimally positioned ground V and flat guideways. The slides rest completely on the machine bed guideways throughout the machine's entire speed range to provide excellent inherent grinding straightness."
STUDER grinding software with StuderPictogramming in a standard integrated StuderTechnology system allows less experienced operators to quickly optimize the potential of the machine, while the more advanced StuderGRIND software makes it possible to efficiently program special applications, including form and thread grinding.
Users can automate the new S33 with a side, gantry or front-load robot system. The various automation and handling options provided by STUDER and United Grinding allow manufacturers to configure the right system for their needs.
