Trigano in France and Baileys in England are among the most renowned caravan manufacturers in Europe. Maka supports the productivity and competitiveness of these companies with high-performance CNC milling centers, which are used to machine caravan floor and side panels made of composite materials with high precision and efficiency. The most successful mobile gantry series from the southern German mechanical engineering specialist are used for this purpose.
The requirements profile of the English-based company Baileys regarding the use of Maka technology related to the economical processing of caravan floor parts made of glued and nailed wooden frames with insulation coating in lengths of up to approximately 7.5 meters.
For these processing operations, Maka supplied a system with a three-axis technology in a mobile gantry design that specifically meets the requirements of caravan construction. This customer-specific special version with a total machine length of around twelve meters offers Baileys the option of processing the universal floor panels using the two-channel technology. In addition to the automatic infeed and outfeed of the panels, the highlights of this PM 210 machine solution are the approximately 44 individually controlled suction cups that are distributed in a grid over the entire work area. The required suction cups are automatically set according to the part size and the specific milling.
Another key feature is the two-channel technology used, which makes it possible to format the floor panels on the long sides at the same time; this is necessary if, for example, wheel arch millings are machined in mirror image. With this technology, milling can be carried out both in mirror image or synchronously with both three-axis units and the active tool correction at the same time.
Bailey's main decision criterion for the Maka solution was the enormous performance of the machine and the ability to work with both units simultaneously; this results in an extraordinarily high saving in the overall processing time. Thus, by alternating use of the units, the tool change times are calculated to 'zero', i.e. one unit works and the other changes the tool for the next work step. This ensures not only process reliability but also cost-effectiveness.
Trigano is a very well-known French caravan manufacturer that is a European leader in the market segment for exclusively equipped caravans. The PM 210 series was also used here, which uses three-axis technology to enable profitable machining of caravan side and floor panels.
This special version impresses with a total length of around 12 meters and offers the company the possibility of processing the panels universally. In addition to the automatic infeed and outfeed of the blanks, the 55 individually controlled suction cups are also a technical highlight of this CNC machining center. These are distributed in a grid over the entire work area and are automatically positioned according to the part size and specific millings. Another special feature is the special protective cabin, which is installed above the double guide system in the Y-axis. Here, the suction system rests on two rails and thus ensures the highest possible protection against dust. The decisive factors for Trigano here were the high performance of the machine and the possibility of integrating the system into an automatic work process. Another criterion was 100% compatibility with the CNC machining FPM 410 delivered in 1999 in order to be able to guarantee an optimal workflow.
Fully automatic processing of individual refrigerated container components
​
The company Bernhard Krone AS in Kjellerup in Denmark specializes in the production of containers for refrigerated vehicles and required a special CNC system for fully automatic processing of the individual refrigerated container components for roof, side, floor and front parts that was able to optimally harmonize the production processes in order to ensure rationality and cost-effectiveness.
The decision was then made in favor of the overall concept from MAKA, which supplied the BC 570 system in bridge construction with a total length of 17 meters for these demanding machining processes. The mobile portal bridge is equipped with a universal robot unit, 20 kW nominal power and a traveling tool chain magazine with 32 tool positions as well as a separate storage space for a saw blade up to a maximum diameter of 500 mm.
The machinable cube size of 3,300 mm x 14,000 mm x 150 mm corresponds to the maximum dimension of the largest component. The panels are retrieved from a semi-automatic warehouse directly in front of the processing system. Due to the different materials to be processed - sandwich construction - made of aluminum, chipboard, PU foam including steel inserts, the installation of a coolant spray system was unavoidable, as, among other things, the introduction of threads into the steel inserts of the roof parts was required.
The longitudinal and transverse processing as well as the 'formatting of the notch cuts' are carried out with the saw blade. The longitudinal waste parts are fed out of the system via a conveyor belt and automatically cut to a maximum length of 300 mm and transported to the waste container. This technology also made it possible to automate the 'waste disposal' and thus corresponded perfectly to the Danish company's ideas.
