PROCESS EQUIPMENT UPDATE
In the automotive industry, for example, throttle valves and magnetic valves in diesel injection systems are manufactured in rotary transfer machines. Cylinder heads for high-pressure pumps or pump housings are also typical applications. In the electrical and electronics industry, copper, aluminium, and their alloys (e.g. brass) are mainly processed into plugs, sockets, terminals, sleeves, or contacts. Lock housings, locking cylinders, and keys are other examples of typical products from rotary transfer machines.
FACT 5: NEW ROTARY TRANSFER MACHINES ARE SUSTAINABLE AS THEY ARE ENERGY-EFFICIENT Compared to a multi-machine production of the same component, the energy savings are enormous with a single rotary transfer machine production, as each machine would need to be supplied with energy separately. Newer rotary transfer machines are equipped with intelligent energy controls, so only the currently active stations are powered, which reduces energy consumption significantly. Compared to conventional machining centres, a rotary transfer machine requires only about half the energy – a decisive competitive advantage in times of high energy prices.
FACT 6: ROTARY TRANSFER MACHINES ARE EXPENSIVE, BUT THE INVESTMENT PAYS OFF Automated production with minimal personnel, high component control
The control system reaches all stations simultaneously. This enables the automated process possible from loading, through high-precision manufacturing with parallel component monitoring, to unloading
and process reliability, very high annual production volumes, and a minimum of four tools required for processing: if these are the requirements to be met, the purchase of a rotary transfer machine can be worthwhile compared to conventional machine tools. Other advantages over multi-machine production include lower investment, less space and personnel requirements, and shorter setup times. Fewer involved employees also mean more homogeneous component quality. A factor that further minimises
investment risk is the high production flexibility of the rotary transfer machine due to its modular design. With proper
maintenance, they have a lifespan of well over 30 years, making them attractive for resale.
The Imoberdorf imo-space provides plenty of space, allowing the machine to be equipped with up to 16 processing stations. The trailing plate ensures maximum accuracy during high-speed production

FACT 7: ROTARY TRANSFER MACHINES ARE ALSO AVAILABLE SECOND-HAND Due to production restructuring, well- maintained rotary transfer machines become available on the second-hand market time and again. At present, Surplex offers a new Imoberdorf imo-space rotary transfer machine with zero process hours, equipped with eight processing stations, a drag tray, and a glass scale for repeat accuracy up to 0.5 µm. As the name suggests, the imo-space design is a machine configuration with plenty of space. A maximum of 16 machining stations and ATC tool changers enable enormous production potential. Surplex is known for its auctions of used machinery, with up to 55,000 industrial goods changing hands annually in over 800 auctions. However, it also offers direct sales of individual, usually particularly outstanding machines. Almost 3,000 direct sales are handled annually by the company Te highest quality machines are not auctioned, but are offered on request. Surplex takes care of the marketing for the sellers using its international network and, if desired, organises logistics and commissioning for buyers.
