5-Axis CNC Grinder with Extended XY Paths



The Schütte 325linear cylindrical grinding system features extended XY paths plus two auxiliary slides.

Optional robotic handling, wheel changing and tool magazines allow for scalable automation.

SIGSpro enables full 3D simulation of the entire cycle, either on the HMI or offline, for improved estimating and safety concerns.

Schütte's 325linear machine is a 5-axis CNC grinder featuring 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. This machine further expands the user's automation possibilities, as 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 also offers scalable automation with available options that include a 140-position tool changer, 5-24 grinding wheel magazine and a flexible robotic tool gripper for changing small micro tools. 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 (<0.0001° resolution) and pitch accuracy, while the XYZ-axis resolution is maintained at <0.1 microns. The swiveling C-axis for the grinding head has a 225° range of motion and also features <0.0001° resolution accuracy. The primary motor spindle operates up to 12,000 RPM with a 15 kW max. drive output, while the grinding spindle option affords a max. speed of 24,000 RPM. Linear axis travel on the machine is 480 mm x 250 mm x 275 mm (XYZ).

The machine is offered with the proprietary Schütte Integrated Grinding Software (SIGSpro) 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 3D 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.

The Schütte 325linear grinding machine is available for viewing at the company's North American headquarters in Jackson, MI, as well as at a number of upcoming trade shows in 2015. For an operational video on this machine, visit http://youtu.be/2gTHHCZHMic
