Investments Machine park renewed and expanded There have been some major investments in production recently at the location in Aerzen. In the past few months, three new machines have been taken into operation, in order to support high-quality and more efficient production. The new flat grinding machine The new machining centre began operations in January. The new CNC turning and milling centreNew flat grinding machine After more than 20 years of operation, the old Favretto machine has been replaced with a compact flat grinding machine model ZT 715 made by Ziersch. Its task is the grinding of rings, bushings, washers, covers and side plates. 70% of the pieces to be processed consist of steel, 20% consist of cast iron and 10% consist of stainless steel. While the old machine could only manage surface roughnesses of up to 4 μm, the new one reaches 1 μm. The spindle power is now 15 kW and the work surface is even larger. It is remarkable how quietly the new machine runs. New machining centre For the processing of housing parts, a new machining centre DMC 160 U duoBlock was procured from Messrs. DMG Mori Seiki GmbH. With this machining centre,in future cylinders and side plates can be manufactured from segment 2. January saw the commissioning and the manufacturing of the first cylinders VM 237 L and suction side plates VM 337 L. Thanks to the 5-axis machining centre, the housing parts can be processed in one clamping. A special feature is the universal milling head with kit motor in heavy-duty version, with a capacity of 52 KW and 2000 Nm. New CNC turning and milling centre As a replacement for the FE0178/0179, in November 2014, the new M65 MILLTURN FE 0176 from the manufacturer WFL in Linz, Austria was taken in operation in hall 21. Four identical machines have hitherto been in operation in the production centre for the complete processing of blower pistons and compressor rotors. The new machine was designed for the range of parts in hall 21. The essential difference from the existing machines is the reinforced design of the turning, drilling and milling unit, as well as the use of processing heads when milling with bigger profile cutters. This will considerably reduce wearin the turning, drilling and milling unit, and will increase the machine’s availability.
