Twin-pallet HMC has high rigidity, fast
traverses
A twin-pallet, horizontal machining centre has high standards of rigidity using a double walled casting structure to carry the heavy duty saddle, column and linear roller guide bearing system.
Qualifying the progress of its machine tool development programme to provide high productivity production solutions, the latest addition to the Hyundai-Kia horizontal machining centre range, the HX630 is boasting a class-leading specification of 50m/min rapid traverse rates The machine has an 8,000 rev/min spindle as standard with a 12,000 rev/min option, a 3s tool change for the BT50 taper tool-holders and a 12s exchange for the 630mm by 630mm pallets able to carry a workpiece load of 1.2 tonnes

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.
Now installed in the Hove, Sussex, UK showroom of C Dugard, the HX630 horizontal machining centre is able to carry and index components on each of its twin-pallets within a cylindrical volume of 930mm diameter by 1000mm high.
The basic single piece T-shaped bed casting sets high standards of rigidity using a double walled casting structure to carry the heavy duty saddle, column and linear roller guide bearing system.
With friction and drag minimised, the machine is able to maximise its advantage with high acceleration to 50m/min rapid traverse rates in each axis.

High-speed vertical turning and machining centres offering production times that are significantly faster than current machines can achieve - with up to 96m/min rapids - cost under GBP 50,000.
Double-acting ballscrew cuts machine downtime
Very fast-moving mill-tap centres, zippy machining centres and a very nippy pick-up spindle vertical turning lathe are the results of applying a double-acting ballscrew axis drive.
Linear scale positioning is available as an option to provide higher accuracy specification if required.
The spindle is powered by a 22kW high torque two-step, gear head motor giving 8,000 rev/min as standard and a high speed built-in 12,000 rev/min option.
The BT50 taper, (CAT50 option), toolholder system is clamped in the spindle with a force of some 2,100kg.
Coolant supply to the cutting zone is via eight nozzle feeders and through-the-tool supply.
There is an option of an high-pressure jet coolant supply system.
Pallet exchange takes just 12s using a lift-to-index and move from the precise four taper cone location which features built-in clamps to ensure maximum rigidity under heavy duty milling and drilling.
A Hurth coupling is used for precise indexing and location.
The tool magazine and double arm exchange is totally isolated from the machining area to prevent ingress of coolant and swarf and utilises a mechanically driven cam based system to enable a tool to tool time of 3s to be achieved.
Tools up to 120mm diameter weighing 15kg can be handled as standard but Hyundai-Kia provides a heavy tool option which will accommodate tools up to 245mm diameter and 25kg in weight.
The tool magazine is chain-type and as standard holds 40 tools.
However, 60, 90 and 120 tool systems are also available.
Control is through Fanuc 18i-MB giving up to six axes of movement and four-axis simultaneous.
Canned cycles are included for roughing, finishing, deep hole and peck drilling, boring, tapping and threading. Request a free brochure from C Dugard ...
