Use of Maija milling discs in combination with robots

Various tests have recently been conducted and documented for this purpose. Two specific applications can be seen in the linked video. Milling is performed dry, i.e., without the use of cooling lubricants or similar substances.

The first test was conducted using a Kuka robot, with the goal of creating a groove in S355 (solid material with burnt edges). A combination of a GAT 115-260 BX/S1 operating at 1,300 rpm and a DoubleWorker 125mm/B10mm with 85 teeth for steel processing was used. The workpiece used was 30 cm long. After a machining time of 7 minutes, a depth of 19 mm was achieved.

In the second case, a portal robot was used. The machine used was the GAT 123-451 BX/S1, and for the first time, a DoubleWorker with 180 mm was employed. The material machined here was stainless steel (austenitic) (solid material) with a length of 100 cm. The goal was to achieve a specified depth (12 mm) in multiple passes. In a total of three passes, 4 mm was machined in each pass at a feed rate of 30 cm/min. During the milling process, the temperature at the milling disc was regularly recorded. A maximum of 100 °C was measured at the bottom of the material and 40 °C at the top.

The goal is to address the challenges in the labor market and help companies implement reliable, high-quality, and future-proof processes. In addition to traditional manual work with hand-held angle cutters and Maija milling discs, the integration of this combination into (semi-)automated processes is also becoming increasingly relevant. For this purpose, various mounts have been developed, for example for use on a robot, to transfer the originally hand-held machines into these processes.
