B-axis toolchanger lathes machine in one
set-up
Rigid and accurate B-axis toolchanger lathes are aimed at OEMs and subcontractors that want to produce complex, high-added-value components in a single set-up.
The Korean machine tool manufacturer, Daewoo, has introduced its first B-axis toolchanger lathes, the new Puma MX2500ST and MX2000, aimed at OEMs and subcontractors that want to produce complex, high-added-value components in a single set-up Weighing around 12 tonnes, the rigid, accurate machines are sized to manufacture parts up to 550mm diameter by 1020mm long

Machining times cut by three-quarters
It used to take Watford-based Parker Hannifin 30 minutes to machine both ends of complex cylinder rods. The same job is now done in seven minutes in a Nakamura Tome TW-20, twin-turret lathe.
Two opposing twin-turret lathes are in one
One of the most capable mill-turning machines ever built, has four turrets, two spindles and offers a total of 13 computer controlled axes.
The MX2500ST will be launched in Europe at the largest ever exhibition of Daewoo CNC machine tools outside Korea.
Called DIMF EUROPA 2004, it will be held at the Leamington Spa showrooms of UK agent, Mills Manufacturing Technology, on the 20th, 21st and 22nd April 2004.
Specification of the multi-axis CNC turning centres is high, so the customer does not pay extra to have advanced mill-turning functionality.

Small horizontal as rugged as the big models
Although the new Daewoo ACE HM500 horizontal machining centre is nominally a half-metre-cube machine, it is constructed using box section guideways normally found on larger machines
VMC machines vaporiser bodies from extruded stock
Anaesthesia equipment manufacturer, Penlon, is using a Daewoo vertical machining centre to produce vaporiser bodies from aluminium extrusions in-house.
It includes 20 bar through-spindle coolant, Sandvik Capto-C6 tooling, and 0.001 degree indexing (ie full C-axis) of the 15kW/10,000 rpm milling spindle, which is mounted on a +/-120 degree B-axis above the spindle centreline.
Capacity of the magazine is 24, 40 or 80 tools, ATC time being 1.5 seconds.
While this is in progress, it is possible to machine using the lower turret on the MX2500ST.
Control system is the Fanuc 18iT-B featuring manual guide operator programming.
It gives inexperienced users a simple, graphical instructions-based method of programming at the machine that does not require knowledge of G codes, even for probing cycles.
Part program editing has the flexibility of cut, copy and paste, powerful simulation of cutting cycles assists visualisation of complex processes, and integration with CAD/CAM systems is seamless.
Tool load monitoring is also standard.
Model MX2500ST is the more capable, as it is equipped with an opposed spindle identical to one on the left, offering 26kW/3,500 rpm, full C-axis and 76mm bar capacity at both ends.
There is a total of 10 CNC axes comprising X,Z,Y and B for the milling spindle, X and Z for the live, 12-station tool turret positioned below the spindles, Z-axis motion of the counter spindle, and the C-axes on the two turning spindles and the milling spindle.
Idle times are minimised by fast linear rapid traverse rates of up to 24m/min.
Take away the lower turret and the opposed spindle, add a tailstock, increase the turning spindle speed to 5,000 rpm, decrease the bar capacity to 65mm, and the result is the MX2000.
Turning tools are clamped in the milling spindle and exchanged in the same way as milling cutters and drills, making this an ideal, low cost machine for small batch production of complex components.
