HARTFORD'S NEW INTELLIGENT FIVE-AXIS MACHINING SOLUTIONS AVAILABLE FROM WARD CNC
With a gantry-type structure and integrated swivel rotary table, Hartford’s new and compact Intelligent 5A-650 machining centre sets new standards in the cost-effective, five-axis production of a wide range of even the most complex parts - courtesy of modular design principles that allow users to select varying spindle head and tool magazine options.
Available from Ward CNC, the exclusive distributor in the UK and Ireland for the Taiwanese builder, the new machine offers a variety of ‘intelligent’ spindle and control options for the guaranteed high-performance, five-axis machining of parts in a single set-up.
The 5A-650 has a work envelope (X, Y and Z axes) of 660 mm by 550 mm by 460 mm and can accommodate loads of 300 kgs. A 25 revs/min 650 mm diameter table on the fourth/fifth axis unit can handle loads of 200 kgs, plus the B axis movement is +110deg to -50deg and there is a C axis rotation of a full 360deg.
As standard, the machine is provided with a 12.5 kW direct drive spindle head and has rapids of 30 m/min plus a 24-tool automatic toolchanger. As options, 20 kW (direct drive) or 24 kW (built-in) spindles can be supplied along with 30-, 40- or 60-tool ATC. Also, the machine can be supplied without rotary table for three-axis applications.
The 24,000 revs/min built-in ‘i-Tech’ spindle can incorporate a variety of ‘smart’ functions for high-speed use - wear diagnostics, thermal displacement compensation and internal cooling for heightened thermal balance and overload protection.
Accurate and consistent machining is guaranteed by the gantry-type construction based on double-wall columns of spheroidal cast iron providing superb damping qualities and which resist the impact of high acceleration/deceleration.
In addition, when used in three-axis mode, the workpiece remains stationary on the base, so loads remain constant. High-performance linear scales are used on the main axis travels, and the cross beam features four linear ways.
Software on the Hartford 5A – 650 is formatted to meet all five-axis demands, including options for Heidenhain dynamic collision monitoring, kinematic 48 touch probing and kinematic comp for volumetric compensation.
