Hydrostatics - Import export

How can large, heavyduty and bulky workpieces be processed without adversely affecting the weight and size of the machining result? The Droop+Rein G/GF series has been specifically developed to tackle this difficult task. The gantry machines reliably prevent dynamic losses through the table and workpiece. The G/GF series has many technical highlights to meet the requirements of complex machining tasks, such as the hydrostatic guide in all linear axes or the thermosymmetrical design of the spool milling unit with an integrated Caxis. Milling heads can be changed automatically via a head change interface. Droop+Rein has developed over 300 different milling heads for a variety of applications such as machining large diesel engines. The option to set up in a second working area during the machining time allows increased productivity.

With the addition of a moveable table, traversing through the twin column portal design of the VC machine range, the VCV provides the ultimate flexibility for machining large components. In addition to the «on center» machining capability of a standard lathe the VCV machines are able to machine eccentric features. With the use of our extensive range of standard milling and drilling attachments, the VCV machine range is capable of full 5 sided machining of components up to 12,000 mm in diameter and 350 tons in weight. On machines with a Yaxis the component can be machined in any position. The turning table is set on a sliding bed. The default Yaxis travel corresponds to the swing diameter of the machine size, but can be tailored to suit any application.

The Dörries CONTUMAT VC series, designed as a double column portal system, is ideal for larger swing diameters of 3,500 to 12,000 mm. The VC range combines all of the advantages of the VCE range with the ability to machine large scale components just as effectively. The positive construction properties of the smaller range are taken over here in correspondingly dimensioned main components. The range also provides high levels of flexibility by combining standard modules, providing the customer with a solution tailored to suit their individual needs. The closed portal construction of the double column vertical lathe guarantees high intrinsic rigidity, while the proven cast construction ensures excellent damping and thermostability. Thanks to these characteristics customers obtain a lathe that provides high machining accuracy, with a long service life.

The compact single column vertical lathe (swing diameters of 1,400 to 2,800 mm) is appropriate not only for turning, but, with additional units, can also be used for drilling, milling and grinding. It means that it is possible, in a single clamping, to carry out a full machining operation on the CONTUMAT VCE and not simply turning. The rigid cast construction on this lathe ensures low vibration and accurate cutting; hydrostatic guide rails damp vibrations even further. The technical design and numerous fitting options mean that Dörries is able to configure an individual machine to every customer.
