Schütte will be showcasing the 325linear machine. The 325linear is a 5-axis CNC grinder with extended X- and Y-axis movement plus two auxiliary slides for workpiece clamping and improved grinding wheel guidance over the entire machining envelope. Micro tools, gun drills, hob cutters and complex geometries can be accommodated on this machine, which typically operates in the range of 2,500-4,000 RPM. The additional second auxiliary slide enables the 325linear to utilize tool guidance, part support, tailstock or workpiece pallets in operation. This Schütte machine further expands the user's automation possibilities, since it also offers advancements in wheel change and robotic workpiece handling.
On the A-axis, a user can install collet chucks, hydraulic expansion chucks or multi-range chucks. With the automated collet changer on the machine, workpieces with different diameters can be clamped with high concentricity in the unmanned loader station. The Schütte A-axis configuration on this machine also permits position-oriented clamping of non-rotationally symmetrical workpieces. In this way, sequential workpieces with various roughing and finishing requirements can be preset on the machine for continuous processing.
This Schütte grinding system offers scalable automation, with a 140-position tool changer, 5-24 grinding wheel magazine and a flexible robotic tool gripper for changing the smallest micro tools as available options. The same base machine can be utilized for continuous production of a single part in a work cell set-up or used for sequential one-off work, as needed.
The 325linear features a universal rotation A-axis with a high level of concentricity (<0.0001º resolution) and pitch accuracy.
The machine is offered with the proprietary SIGSpro (Schütte Integrated Grinding Software) as the programming interface, allowing users to assign clamping options for each grinding operation being performed. When the support and tool guidance system are used, preset distances from the grinding wheel to the workpiece can be defined and held constant. In the 3-D mode, all cycle steps can be simulated, controlled and optimized for exact estimating, collision avoidance and even external workstation integration with the other workpieces.
All motion control on this grinder is maintained on a Siemens 840D sl CNC with compatible drive technology.
