High performance tools for manufacturing
The market for electrically powered tools – known as „power tools“ in this sector – is growing throughout the world. Particularly in demand by the pros are high-quality, branded products that combine maximum performance with user-friendly handling. This combination is made possible among other things by housings of extremely robust lightweight metals, which in turn make high demands on the tools used for machining them. That‘s why during the development of a new 16 kilo percussion hammer Bosch placed its trust in the experience of the experts at LMT Kieninger.
The 16 kilo percussion hammer launched 2007 by Bosch sets a new standard for power tools in demolition work. In spite of its extremely high force of impact – the GSH 16 demolishes around 1,700 kilos of B25/30 class concrete per hour – the tool is relatively light and has little vibration. This guarantees skilled workers user-friendly handling and minimum physical stress.
Involved from the beginning: the machining pros at LMT Kieninger
A critical component of the new power hammer is its housing of lightweight metal. Because the same requirements obtain more or less for the production of tools as for their use in practice – high efficiency and maximum operating times – Bosch collaborated intensively with the machining experts at LMT Kieninger during the planning of the production process. This company of the Leitz Metalworking Technology Group has an excellent reputation, above all as a supplier of special tools and milling systems throughout industry including the automotive and aerospace sectors. Accordingly the Kieninger team could call upon its comprehensive experience in machining demanding lightweight metals, as they are used for example in modern motors, during the development and design of the special tool for Bosch.
Efficient production: machining a workpiece so that it is ready for installation
The tool itself is a so-called monoblock construction. This means that the cutters for the various machining steps are mounted on a common base. They are attached to this either via soldering or by means of short tool holders.
At Bosch a tool is used with soldered cutters of poly-crystalline diamond (PKD). This extremely hard cutting material guarantees the highest machining performance and long tool lives for high-performance machining. Because of the monoblock construction of the tool and its optimised cutting geometry the housing is machined ready for installation, and the set-up and other preparation times are reduced to a minimum. In view of Bosch‘s favourable experience and the growth predictions for professional standard power tools the people at Kieninger are sure that their high-performance tools will continue to make a major contribution in the future in optimising the production of power tools
