Vertical production milling has robot
handling
A linear motor equipped, travelling column VMC integrated with a fast-acting robot is setting new standards in dynamic response and productivity, says the builder.
The new vertical machining centres DMP 45/60 V linear from Deckel Maho are setting standards in dynamic response and productivity Examples are the extremely short chip-to-chip time of 1.8 seconds and the linear drive on the X axis for max

With the highly productive DMU 50 / 70 eVolution, DMG has added a new dimension to universal milling and drilling machines designed to save up to 20% on machining times.
rapid traverses of 80m/min and accelerations over 1G.
Yet these new machining centres can do a lot more: thanks to the integrated 18,000 rev/min motor spindle delivering 25kW and 130Nm, extremely high removal rates are possible with no detriment to excellent contour precision.
The DMP 45/60 V linear is designed as a travelling column machine, i.e all three axes lie in the tool.

Bar feeder has high capacity
SACO's new bar feeder reduces idle times and offers high precision and flexibility. Idle time for bar feeding to the collet is considerably reduced.
FEM was used to maximise the stability of and dimension all component designs.
This also applies to the change table that takes a new workpiece during the actual production time and replaces the machined part with the new one in less than three seconds.
At EMO, Deckel Maho combined highly productive vertical machining centres with a high-tech automation concept from Fanuc - consisting of a 3D CNC unit, electrical systems, servo or linear drives, and a robot system.
This new machining cell therefore presents itself as the convincing result of a development project between partners from two leading global groups in machine tool building.
The decisive feature differentiating this from conventional automation solutions is the robot system's high degree of integration in the machine concept of the DMP 45/60 V linear.
For example, the robot is mechanically coupled to the machine, which always creates identical general conditions for programming.
On the other hand, software modules can be used to operate the complete machining cell alone from the CNC system: an additional robot control console becomes superfluous.
Moreover, this high integration gives rise to an extremely compact design: including the vertical machining centre, the robot system, and a module for the internal supply of coolant, the machining cell requires a floor area of solely 16m2.
In Milan Deckel Maho gave an exemplary presentation of the high-end design with a vision system facilitating the chaotic provision of workpieces.
The robot is fitted with optical detectors and so recognises the geometry of the part, at the same time initiating both the suitable robot and manufacturing program.
