Automatic work piece changing equipment reduces set-up down time with increased manufacturing flexibility.
Dörries CONTUMAT VC 4500
High process reliability thanks to highly customised application-oriented technology solutions
Palletizing options with automatic workpiece changing equipment reduce set-up down times with increased manufacturing flexibility.
The vibration-damping two-column cast construction and generously dimensioned main components guarantee a long service life and maximum machining accuracy.
vertical turning lathe
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 thermo-stability. Thanks to these characteristics customers obtain a lathe that provides high machining accuracy, with a long service life.
Dörries lathes offer flexible tool handling systems. The multifunctional disc magazin offers up to 72 pockets, the chain type magazine up to 100 pockets and the column magazine with double gripper unit up to 210 pockets.
A wide variety of head attachments are available. These could be angular milling heads, universal-swivel heads, facing heads or grinding spindles.
The machine can be adapted with a boring and milling drive of 37 kW. Also grinding operations are optinal possible.
The main drive is powered by one or two electrically preloaded drive units with asynchronous motors. The power is max. 2 x 60 kW. The version with two motors (master-slave principle) permits exact positioning and feed motion of the machine tables in a numerically-controlled C-axis for boring and milling, as well as the highest dynamics in tuning.
The cast iron design of the main components leads to a vibration damping design. All main machine groups are calculated and optimised using the Finite-Element Methode (FEM) regarding stiffness and cross sections.
Basically two tool holder systems are available for Dörries lathes. One for powerfull turning operations and the other one if boring and milling operations are additionally required.
For various types of workpieces different clamping solutions are available. Tables for jaw boxes, with inserted basic sliders, with hydraulic power chucks or with magnetic power chucks. The table load is max. 350000 kg.
The crossrail offers hydrostatic guiding in the x-axis. The guiding width is 700 - 1500 mm. The crossrails are hydrostatically clamped.
The cast iron ram design consists a closed hydrostatic guide system. Ram section of 300 x 300 mm or 480 x 400 mm are available. Z-stroke options of 1500 mm to 3500 mm are possible.
