Vertical turning lathes mill and grind
too
A range of elevating cross rail-type vertical turning lathes machine parts up to 2.8m diameter by 1.6m height, including milling, drilling and, optionally, grinding too.
C Dugard of Hove, UK, has introduced a range of You-Ji elevating cross rail-type vertical turning lathes (VTL) with a turning diameter up to 2.8m and 1.6m turning height The VTLs have motors up to 75kW driving through a high torque ZF gearbox with dual speed drive

Travelling column VMC has dual-pallet indexing
Vertical machining centre with a travelling column design and integrated rotary dual-pallet indexing system provides higher levels of productivity and output and efficient workpiece loading/unloading.
Wide range of CNC machines will suit all tastes
High speed lathes, as well as vertical and horizontal machining centres, to suit all tastes, will be exhibited at Mach 2002 by C Dugard.
The VTLs perform turning, milling and grinding cycles.
The machines can carry hydraulic chucks with up to six jaws.
Drilling heads for 90 deg approach can be specified as well as a grinding spindle option and automatic pallet and tool changer.
There are further options of through tool coolant supply and a 25kW live machining spindle.
The You-Ji range is designated 1000, 1200, 1600, 2000 and 2500.
* High stability and rigidity - high stability and rigidity are achieved through the use of a heavy box-section structure of the column to support the sliding cross rail.
The machines accommodate non-symmetrical work and heavy cutting conditions.
The base is heavily walled and multi-ribbed for rigidity and to retain high thermal stability when supporting workloads up to 15 tonnes.
* High torque - the high precision CF-axis gearbox with worm and wheel drive is able to deliver a maximum torque up to 17,500Nm and provides a positioning accuracy of 15 sec of arc, enabling multiple angles and cam shapes, for instance, to be machined.
When worked in conjunction with the X- and Z-axis of the ram, the machine range can perform a more universal role of a machining centre.
In addition to conventional turning, facing and boring, the VTLs enable off-centre operations to include driven tools through the 90 deg angle head, as well as boring, tapping, U-drilling, face milling and milling.
Tool pre-setting and workpiece probing is available.
A BT50 tool disk magazine is standard with 16 positions and is able to accept tools weighing up to 50kg.
There are four further options of magazines with capacities of 24, 32, 48 and 60 tools.
Control is via Fanuc 18i-T or Siemens 840D and linear scales are available for higher accuracy positioning as an option. Request a free brochure from C Dugard ...
