Production Machining in Germany
This week I’m reporting from the Schwabian region of Germany, where metalworking has deep roots and good technology.
Schwanog Sales Manager Peter Schöninger in the company's production area which boasts five-axis CNC grinding centers from Germany-based Haas and fully automated Agie EDM machines.
Automated CNC grinding centers ensure efficient production processes and short lead times. Typical batch sizes for Schwanog are ranging from three to 50 form tools per order.
The Schwanog tool system consists of a Schwanog tool holder and an insert blank. Part-specific contours are ground or wire-cut into the insert blank. The form tools are suitable for single and multi-spindle lathes as well as CNC and Swiss-type lathes.
Weisser is a global manufacturer of precision turning centers, which are well-known in the automotive industry. The company, which was founded in 1856, produces 250 machines per year on a production area of 18.000 square meters.
Cihan Yanpinar, area manager Americas at Weisser, explains the machines' functionality. Due to their modularity, the machines are suitable for hard turning, out-of-round turning, rotational turning, drilling, thread-cutting, milling and grinding in one setup.
Chris Koepfer, PM editor-in-chief, accompanied by his colleagues, listens closely to Cihan Yanpinar's presentation during a Weisser's plant tour.
Weisser builds single-spindle pick-up precision lathes for chuck-held turned parts, as well as highly productive twin-spindle pick-up lathes for synchronous processing of two workpieces or processing in two clampings.
Burkhardt + Weber make machines the size of houses, and I don’t think many will find their way into your shops, since these machines are bigger than many shops!
We saw a promising new tooling system from Goeltenbodt for Swiss-type automatics.

This week I’m reporting from the Schwabian region of Germany, where metalworking has deep roots and good technology. I’m accompanied by Barbara Schulz who is our European correspondent and represents our sister publication, Modern Machine Shop, on this tour. We arrived on Sunday, we rested and started our trek on Monday.
Our first stop was Schwanog, which manufactures custom form cutting tools for the precision machining industry. With production facilities in the U.S., France and Eastern Europe, along with distribution worldwide, this 100-employee company has created a global reach.
Our second visit on Monday was 160-year-old lathe builder, Weisser. This family-owed company is in its 6th generation and supplied sophisticated turning equipment to the automotive industry. We learned about a process the company calls rotational turning, which is a combination of turning and grinding. It eliminates turning lines on the finished workpiece.
On Tuesday, we visited Burkhardt + Weber. The company makes machines the size of houses, and I don’t think many will find their way into your shops. They are bigger than some of your shops! However, I have some background in this technology (life before PM) and enjoyed my conversation with the company’s engaging CEO Olaf Furtmeier. He spent four hours with us, as we discussed the ins and outs of the large machine tool market.
The last stop on Tuesday was with toolholder manufacturer Goeltenbodt. Long known for its multi-spindle toolholders, the company is moving into quick-change toolholders and have an interesting solution. It’s new and so far applicable to Tsugami and Star. However, Thomas Flache, head of sales and technology, told me many other brands’ holder in development and response has been strong.
The system involves fabricating a machine-specific gang tool plate that allows stick tooling to be quickly exchanged and preset off line. They also offer a simple, yet effective, presetter as well.
