Switzerland-based Fritz Studer AG, the internationally renowned manufacturer of high-end cylindrical grinding machines, has introduced insertLoad, a new automation solution to support the loading and unloading of its S33 and S31 universal cylindrical grinding machines — it can load workpieces between centres and into the chuck.

Where customised solutions were previously necessary, the new universal loading system from Studer now enables standardised automation for loading and unloading the S33 and S31. insertLoad can be used for centre distances of up to 1,000mm, thus closing a gap in standardised automation systems — the workpieces can be up to 100mm long and weigh 1.5kg in alternating mode or 5kg in a single mode. The sophisticated design and the ease-of-use with the digital set up wizard allow users to configure this themselves for centres and chucks — no programming knowledge is required. Furthermore, insertLoad can handle workpieces that are stored either vertically or horizontally.

The new Studer loader combines the advantages of a standardised system with great flexibility. It handles a wide variety of parts in terms of geometry, weight, and size; even the capacity of the drawers and the degree of autonomy can be adapted based on the needs and requirements. Loading and unloading is handled by a Fanuc robot, which moves independently on a linear axis between the loader and the machine’s work area. Typically, the time without human operator intervention is between 30 and 60min.

Studer placed particular emphasis on safety during development. For example, a loading hatch separates the loading area of the insertLoad from the working area of the machine to prevent ‘flame flashback’ during machining processes using grinding oil. In addition, the software and a safety switch ensure that grinding technicians are not endangered in the event of a deflagration.

Initially, insertload is only available for S33 and S31 CNC universal cylindrical grinding machines, but plans are in place for it to be rolled out for use with other Studer models. The S33 and S31 are ideal grinding solutions for small to large workpieces in single, small batches and volume production. Both machines feature distances between centres of 400 to 1,600mm and a centre height of 175mm.
