Machine tools accomplish diverse processes in the metal working industry, e.g. turning, milling, grinding, punching. Every second counts, especially in large batch production: the productivity is a highly crucial factor to determine the competitive advantages of a machine tool.

As machinery safety is regarded, this means that the safety guards must not affect or interfere with the productivity. The Schmersal Group develops powerful safety systems for the machine tool construction in accordance with this principle for many decennia already.

According to studies, the tampering of the safety devices installed on machinery however is unfortunately standard practice in one-third of the metal-working companies. This risk can be minimised in a simple manner by means of coded safety switches and safety sensors as well as hinge safety switches.

Interruptions of the production process are unwanted, and not just because of productivity reasons. When the operator opens the safety guard of a boring mill, thus interrupting the process, both the drill bit and the workpiece can be damaged.

This explains the above-average use of solenoid interlocks in machine tools. These devices keep the safety guard closed as long as the process is running. For these applications, the Schmersal Group offers an extremely comprehensive range of products for various requirements - ranging from a compact solenoid interlock for small safety guards to a three-point interlock for very large safety guards and a modular system for protection walkable hazardous areas.

Ergonomics is another important aspect of safety at the man-machine interface. After all, a machine with directly accessible operating elements enabling an intuitive operation runs safer. The Schmersal Group is convinced of that. That is why the programme includes for instance the operating panels of the BDF series, which can be directly installed onto conventional profile systems. By means of the command and signalling devices of the R series, complete operating panels can be configured.

Wherever man and machine must collaborate, special safety measures are required. This applies for instance to the feed and withdrawal areas on presses - here, optoelectronic safety devices from the Schmersal Group are used. Schmersal moreover is developping custommade solutions enabling a safe collaboration between man and robot without separating protective fence for more than ten years already.
