Drill/tap centres machine aluminium
Drill/tap machining centres are for use in the high-volume production of complex aluminium parts that require fast, reliable and cost-efficient drill/tap machining.
Hardinge Machine Tools has added introduced a range of high performance, purpose-built drill/tap machining centres to its range of milling machines The compact Bridgeport GX 480 DT machines drill/tap machining centres are intended for manufacturers involved in high volume production of precise and complex aluminium parts that require fast, reliable and cost efficient drill/tap machining

Added performance and capability at no extra cost on all of the Hardinge produced VMC II range, which have been enhanced with new spindle drives and motors and still start at GBP32,000.
Hardinge speeds up pick-up spindle VTL working
The revolutionary Hardinge / EMAG joint venture produced VL machines provide a guaranteed load / unload time of 4 - 6 seconds - chip to chip - which is critical for cycles of 30 sec and less.
Typical sector applications include: communications, electronics, automotive and so on.
The machines have a rigid C-frame, fixed column design.
The machines' spindle carrier, column and base are constructed from high quality cast iron.
This construction - plus high performance linear guideways improve machining performance, protect tool life and ensure consistent high positioning accuracy (+/-0.005mm) and repeatability (0.002mm).
GX 480 DT machines are equipped with a 5.5kW 15,000 rev/min direct drive ISO 30 spindle that produces 17.5Nm torque and a maximum tapping speed of 6,000 rev/min.
This power, combined with 48m/min rapid feeds on all axes, 1G acceleration/deceleration and 14-position (turret-type) or 20-position (swing-arm) ATC with 1.5/0.8 second tool change time - provides customers with a quick and responsive machine that both reduces non-cutting times and improves duty cycle times.
The machine's performance characteristics are complemented by its versatility.
A good working envelope, despite its compact size, delivers manufacturing flexibility - whilst its high efficiency coolant (100 litre tank capacity) and chip removal system ensure that optimum cutting conditions are maintained in the work area - vital for long and uninterrupted machining operations.
The machine is equipped with a Fanuc 0iMC control with 256KB memory and is supplied with custom-made/ready to use mill and tap macros that save time, simplify programming and eliminate input error.
At the EMO 2007 exhibition, Hardinge will show a GX 480 DT APC (twin automated pallet change) machine equipped with Renishaw probes for workpiece and tool measurement.
This twin-pallet machine extends the already-high productivity and performance of the GX 480 DT machines still further.
