United Grinding’s STUDER roboLoad

With the STUDER roboLoad system, United Grinding offers manufacturers simple, part-loading automation for CNC radius internal grinding machines such as the company’s STUDER S121, S131 and S141. Loader integration was difficult on these types of machines because of the height of their workheads and geometric restrictions. The new STUDER loader meets the geometrical requirements and has a small footprint and an exceptional price-performance ratio, operating without any programming knowledge, allowing for greater production flexibility, and a high degree of operating comfort.

On the STUDER S121, S131, and S141 machines, often used to produce dies for the packaging industry, automatic B axes swivel in a range from -60° to +91°. Any automation must be able to exit the machine and give the B axis the freedom to swivel.

As an external loader, STUDER roboLoad measures only 59.06" (1.50 m) wide: half the width of the machine, saving valuable shop floor space, and offering plenty of room for workpieces manually loaded on six trays, each measuring 42.52" x 12.6” (1080 mm x 320 mm), within a small work area. 

Operators can bring up any grinding program for the workpieces, and the STUDER roboLoad processes them and places each workpiece back in the same place after machining.

For simplicity of operation, the STUDER roboLoad incorporates a setup wizard developed by automation specialists from WENGER of Winterthur, Switzerland. It requires no programming knowledge on the part of the setter or machine operator.
