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 8,000revs/min spindle as standard with a 12,000revs/ 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 1.2tonnes.

Now installed in the Hove, Sussex 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 1,000mm 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 said to be able to maximise its advantage with high acceleration to 50m/min rapid traverse rates in each axis. 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 8,000revs/min as standard and a high speed built-in 12,000revs/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 reportedly takes just 12 secs 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 three sees 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 18J-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.
