The Karlsruhe company supplies nanometer-precision positioning technology. During the founding years, research and higher education were the main customers of the company. In the meantime the company in Karlsruhe now serves the Semiconductor technology, automotive industry, biotech PI has been developing and manufacturing standard and OEM products with piezo or motor drives for more than 40 years. In addition to four locations in Germany, the PI Group is represented internationally by fifteen sales and service subsidiaries. The youngest member of the Physik Instrumente Group is ACS Motion Control, a company in Israel that joined the group in 2017. History and structureThe company headquarters is in Karlsruhe, which is in the federal state of Baden-Wuerttemberg, Germany. The company is privately managed and enjoys healthy growth. There are four production sites in Germany:
TechnologySince the 1970s, the focus at PI has been on the use of piezo technology as a drive system for technology. PI (Physik Instrumente) depends on in-house vertical integration as well as in-depth production and technology. It was particularly the piezo technology that led to the foundation of the PI Ceramic subsidiary in 1992, which manufactures the piezo components and piezo actuators that are built into the nanopositioning products of PI. In the last few years, PI has put its focus on new key areas outside of piezo technology and extended its own development and research into the fields of linear motors and related technologies. Related technologies such as air bearing [3] and industrial controllers[4] were supported by acquiring other companies. Business sectorsThe technologies from Physik Instrumente are used in various different applications in industry and science. PI's markets and applications are:[5]
ApplicationsSince the seventies, the automotive industry all over the world has been putting its trust in industrial robots[6].In the past, robots and production staff worked separately from each other. Today, it is perfectly normal to see both robots and hexapods working together on the production line[7]. Car manufacturers use the parallel-kinematic system in conjunction with the classical industrial robots. The precision motion and positioning of the hexapod[8] compensates any inaccuracies of the robot arm. The hexapod then positions a car door for example, and the production line staff can continue with performing the manual work steps. This allows loads to be positioned with micrometer accuracy. The Webinar in the specialist magazine elektrotechnik.de provides more information on that.[9] In the past, it was not possible to make use of commercially available plastic granulate for the additive manufacturing. The mechanical engineers at Arburg did some research and now rely on piezo ManufacturingPI manufactures in seven autonomous organizational units, so-called fractals. Each fractal[13] is responsible for its own product line and is equipped with all necessary production equipment. It operates independently and controls all processes from the receipt of order and materials procurement through assembly and quality testing up to dispatch. The fractals have the following advantages: 1. Faster and more flexible adaptation of production to customer requirements 2. Faster implementation of customized solutions 3. Shorter lead times due to shorter processing times[14] "The concept of the fractal factory" as described by Mr. Warnecke is more relevant than ever and gives a real sense of purpose to a large number of companies in the manufacturing industry in Germany as well as the rest of the world", explains Professor Thomas Bauernhansl, Head of the Fraunhofer IPA Institute. PI has a heavy-load hall for assembling and measuring masses up to five tons. Here, three gantry cranes span the working area to lift and transport the components of the positioning systems. A ground granite slab with a flatness of 3.8 µm serves as assembly area. Air-cushioning elements decouple the granite slab from external vibration. This allows the axes to be aligned accurately during assembly. The lifting and rotating equipment allows payloads up to seven tons to be rotated smoothly around 360°. This makes it possible for example, to qualify behavior and specification of heavy-duty hexapods under realistic load conditions.
