With a gantry-type structure and integrated swivel rotary table, Hartford’s new and compact Intelligent 5A-650 machining centre claims to set new standards in the cost-effective, 5-axis production of a wide range of parts courtesy of modular design principles that allow users to select varying spindle head and tool magazine options.
Available from TW Ward CNC Machinery, 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 high performance, 5-axis machining of parts in a single set-up.
The 5A-650 has a work envelope (X-, Y- and Z-axes) of 660mm by 550mm by 460mm and can accommodate loads of 300kg. A 25rpm/650mm diameter table on the fourth/fifth axis unit can handle loads of 200kg, plus the B-axis movement is +110°/-50° and there is a full 360° C-axis rotation.
As standard, the machine is provided with a 12.5kW direct drive spindle head with rapids of 30m/minute plus a 24 tool automatic toolchanger. As options, 20kW (direct drive) or 24kW (built-in) spindles can be supplied along with 30, 40 or 60 tool ATC. Also, the machine can be supplied without rotary table for 3-axis applications.
The 24,000rpm 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 solid damping qualities and resistance to the impact of high acceleration/deceleration.
In addition, when used in 3-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 5-axis demands, including options for Heidenhain dynamic collision monitoring, kinematic 48 touch probing and kinematic comp for volumetric compensation.
