Recknagel Präzisionsstahl
50-tonne machine floats into production hall
At one million euros, the new CNC machining centre is the most expensive single investment made by the Hückeswagen-based company Recknagel Präzisionsstahl. On Tuesday, the huge machine was delivered in two parts and manoeuvred into the hall in a complex process. This is how the procedure went...
Precision is part of everyday life at Peter Recknagel. After all, his company has been producing exactly that for almost 60 years: precision steel. That's exactly how precise things have to be on this Tuesday morning, as the new CNC machining centre from Schöppingen-based AXA is transported in two parts on low-loaders with the help of two mobile cranes to the dispatch hall and from there a good 25 metres further by forklift truck and heavy-duty rollers to its location in the grinding shop.
However, both the fitters from AXA, where the ‘machine monster’ was manufactured, and the employees of the Dutch company Rensink, which specialises in machine relocations and special transports, had the situation under control. By 11.30 a.m., the two parts, each 13 metres long, four metres high and five metres wide, had already been driven through the hall door, and by the afternoon the machine was in place. However, it will probably take until the end of next week before the final assembly.
At 2.45 a.m., the journey started with two heavy goods vehicles from the manufacturer in Münsterland in the direction of Bergisches Land, and by 5.30 a.m. the convoy had arrived in Kobeshofen. One truck had positioned itself in the Aldi car park opposite so that it only had to reverse across the road to the Recknagel haulage company's roller shutter door, while the other was waiting in the car park of the meat market. To the left and right of the gate were a crane lorry from the Dutch company and one from Wuppertal.
At 9.52 a.m., the first, 31-tonne half - the so-called machine bed with the tool magazines, the guides and drives as well as the travelling column with the processing spindle - starts to move. Centimetre by centimetre, the two cranes lift the huge part into the air. Five minutes later, it floats so high that the heavy goods transporter with the long trailer can drive towards the Aldi car park.
Now the real precision work begins, because somehow the 13 metre long machine half has to get inside. First, thanks to the two cranes, it floats two metres into the dispatch hall and is set down on two heavy-duty rollers at the front. The steel chains with which it was suspended from the Dutch crane are released. Now the Wuppertal crane, whose chains are attached to the rear third of the machine, can push the 30 tonnes in piece by piece until the chains reach the door frame.
Meanwhile, a Rensink employee has brought out a special ‘toy’: using a remote control, he moves a heavy-duty roller measuring a good 1.50 by 1.50 metres from a flat ‘garage’ into the hall - this is of great importance for the onward transport of the two halves into the neighbouring production hall.
Once the second half has been transported to its future location in the same way, preparations can begin for the installation of the new state-of-the-art CNC machining centre. In the afternoon, the two parts are bolted together and initially brought into their prepared position with the help of hydraulic lifters and the heavy-duty rollers. The fitters now mark the points for the holes in the hall foundation, then the CNC machine is moved aside again. Today and after the long weekend, the largest single investment in the company's history, at a good one million euros, will not only be fixed to the hall floor with screws by the end of next week, but will also be prepared for subsequent operation.
Precision machine parts ‘made by Recknagel’ can then be manufactured on it from around mid-May. These are primarily steel guide rails that are ordered by mechanical engineering companies and over which the moving parts in their machines travel. The products from Kobeshofen are primarily used in grinding or milling machines and presses, as well as in toolmaking and by automotive suppliers. For example, Recknagel supplies customers from Audi, VW and Mercedes - ‘but only in small volumes’. As a rule, it is German SMEs that order the products; one company is Klingelnberg from Hückeswagen.
‘With the new machining centre, we now have a modern machine with a more powerful drive that can handle all drilling and milling work,’ explains Recknagel. Fewer work steps are also necessary. Thanks to the rotating machining spindle, holes and threads can now also be drilled and milled from the side. Previously, this was only possible at the sister company in Thuringia.

Largest single investment in the company's history
With this investment, the Hückeswagen-based company Recknagel is securing the site in Kobeshofen for the coming years. However, the decision to place the order almost a year ago was not an easy one in view of the difficult economic situation.Recknagel Präzsionsstahl on Stahlschmidtsbrücke is looking forward to next Tuesday with excitement - and also to the night before. Because on Tuesday morning, the new ‘AXA’ CNC machining centre will be installed in Kobeshofen. ‘This machine is the largest single investment in the company's almost 60-year history - both in terms of the investment sum of almost exactly one million euros and in terms of its dimensions,’ reports company boss Peter Recknagel.
According to him, the machine is around five metres wide and 13 metres long and will therefore be delivered on Tuesday night on three lorries, two of which are heavy goods vehicles with a police escort. Two mobile cranes are planned for unloading.
The travelling column machining centre was built at AXA Maschinenbau GmbH in Schöppingen in Münsterland using precision guide rails made of high-strength Swedish tool steel ‘TOOLOX 44’ - ‘from our company, of course’, says Recknagel.
With this investment, Recknagel is securing the site in Kobeshofen for the coming years. The decision to place the order almost a year ago was not an easy one in view of the difficult economic situation, reports the boss. But not investing was not an option for Recknagel. The previous CNC machine from 2006 will be retained, especially for training and preparatory work, which was previously carried out at the Recknagel plant in Thuringia for capacity reasons.
According to Recknagel, the new AXA has an additional CNC axis so that long components up to four and a half metres in length can also be machined on the face side without retooling. The latest CNC control generation ‘Heidenhain TNC 7’ and the TOOLOX guide rails are the basis for future viability. A tool magazine with 144 tools and a spindle drive with 540 Nm torque and 56 kW power enable powerful yet precise machining.
High-precision mechanical engineering components are manufactured in Hückeswagen, in particular customised guide pads for customers primarily in Germany and Europe. The finished machines are then shipped all over the world.
‘For such a valuable machine, however, the CNC specialists are also valuable in order to be able to work economically. All of the employees working on this machine were trained as cutting machine operators at Recknagel in Hückeswagen,’ reports the boss. Recknagel has therefore also been a founding partner of the Hückeswagen Vocational College for 15 years.
