Engineering precisely what value
The second machine cuts (even) better - FOGS 40 68 C in toolmaking
Schmedthenke Werkzeugbau ordered a second Droop+Rein milling machine with overhead gantry (Droop+Rein FOGS) from Starrag Technology GmbH, which began operation at the same time as the other FOG machine shut down for retrofitting.
In Gütersloh, the success of a secondhand Droop+Rein FOG 2500 has paid off. In 2017, the machine underwent another retrofit, in which the golden oldie (built in 1994) was given new drive technology and a new control system, meaning it can now machine parts from high-alloy castings. According to Jörg and Carsten Schmedthenke, Managing Directors of SWB Schmedthenke Werkzeugbau GmbH in Gütersloh, the machine has smoothed “sensationally“ since the retrofits.
In 2016 – thanks to the enormous success of the old Droop+Rein machine – they ordered a second one: The Droop+Rein FOGS 40 68 C is also a five-axis machine tool designed for smoothing (X axis: 6,800 mm; Y axis: 4,000 mm, Z axis: 1,500 mm, C axis: ± 200 °, B axis: ± 115 °; pallet: 6,000 mm x 3,000 mm, changer for 51 tools, fork head with two motor spindles, 10,000 rpm or 20,000 rpm) with a Heidenhain control system that is tried and tested in toolmaking (iTNC 530 HSCI).
”With the second machine, we‘re smoothing all of the components for the automotive sector“, says Managing Director Jörg Schmedthenke. ”The investment in a second FOGS machine also provides more security in the event that one machine fails.“ Indeed, the new Droop+Rein FOGS took over the work of the first machine when it underwent 22 weeks of planned downtime for retrofitting. ”It was very important for us to have a supplier on whom we could rely completely in terms of meeting deadlines and commitments“, says the Managing Director. ”We agreed on a nine-month delivery time, and Starrag met this 100 %.“ Equally important to the East Westphalia-based company was a very high level of availability, which was at over 95 % shortly after commissioning. This reliability was not only thanks to the FOG series but also, according to Schmedthenke, down to the Starrag staff, who ”were extremely knowledgeable and paid close attention to detail, down to the last 100th of a millimetre“ during assembly.
In line with the Starrag claim ”Engineering precisely what you value“, Schmedthenke thus received a machine with all the features they wanted exactly when they needed it. This meant it went into reliable operation four weeks after setup, precisely when the Droop+Rein FOG 2500 was due to be shut down. The East Westphalia-based company is now using the second machine purely for smooth ing. ”With an additional drive, we could also use it for roughing“, empha sises the qualified engineer. ”But because of our two-machine strategy, we‘ve decided to employ a machine just for smoothing. The precision needed in toolmaking can only be achieved by roughing on one machine and smoothing on another.“
