Space saving Emco's VT 400 extends large workpiece capability

The Vertical 400 extends the capacity of Emco's vertical lathe machine series. It fits chuck parts with up to 400 mm clamping diameters and 450 mm swing diameters, 200 mm length and 40 kg weight, and enables users to alternate lathe work with additional drilling and milling. This is offered by a compact 6.2 m2 footprint machine.

The Emco Vertical 400's automation concept enables customer-specific solutions. As the pick-up system removes the need for additional workpiece loading systems, machine linkage and technical adaptation are easily tailored to each customer's needs. The main spindle carries out the movements in the X and Z axes, and the workpiece arrangement ensures a free chip fall. The welded steel construction of the rigid, vibration-absorbing machine bed and thermo-symmetrical construction of the headstock are specified to withstand heavy use. High rigidity permits large distances between the guide tracks of the slide system and 55/45 linear carriage. The digitally controlled synchronous main spindle motor provides up to 36 kW drive power, 4,000 rpm and 600 Nm torque in line with heavy duty applications. Directly driven ballscrew spindles from 40 mm dia, with backlash and maintenance-free claw couplings, enable speeds up to 45 m/min. The XYZ travel distances are 960, 400 and ±90 mm respectively. In case of Z-axis power failure, mechanical weight compensation prevents the Z-axis from falling. Both the inner and the outer machine casings are designed for low maintenance. The stainless steel covers and wipers do not require telescopes; while guides and seals are protected from flying chips. The completely sealed casing supports economical and ecological extraction since the machine door stays closed even when picking up a new workpiece. Two versions of the VT 400 are available together with various options. In addition to the basic version without Y-axis, a version with the moving turret axis and driven tools offers the advantages of complete processing. Optionally, a multi-function panel can be selected, as well as stationary or driven tools. This also applies to long drill and perforating tools. The user can also implement the VT 400 linear optical measurement systems, process monitoring and electronic analysis.
