Machining Centers

GS-SERIES

The ALZMETALL GS series was designed to combine rigidity and damping properties. The thermo-symmetrical structure of the entire base frame – right down to the spindle – always reliably controls the force transmission during the machining process. The advantages are maximum accuracy and machining precision on the workpiece as well as maximum cutting performance – even in heavy-duty cutting.

Solid, rigid base frame made of grey cast iron
Dynamic stressed machine coponents are made of nodular cast iron
ALZMETALL-specific gantry concept (ASGK) with box-in-box system
Fourfold linear guide system in the Z slide (Z axis)
Rotation axes (A and C axis) with torque drives, optional
Hybrid machining (miling, turning, grinding) in one wordpiece setup

BENEFIT FOR USER

Closed power flow between workpiece and tool as well as geometrically symmetrical structure of the X-Y-Z coordinate carriage

GRANTS
- Thermal stability at Tool Center Point (TCP) in X-Y-plane without compnsation
- Reduction of tool costs
OPTIMIZES
- Contour accuracy at high path speeds
- Lifetime of main spindle

GUARANTEES
- Extremely high parallel traversing accuracy due to double drives in the X and Y axes
- Significantly lower Total Cost of Ownership (TCO) over the lifetime of the machine

TRAVEL SYSTEM CARRIAGE

Design Caracteristics

Carriage designed as a Box-in-Box system with symmetrical structure and restrained mono block cross slide as well as integrated Z-axis slide and motor spindle.

Multiple guide-ways in all linear axes.

Single and double ball screws with Servo drives of the linear axes.

NC SWIVEL AND ROTARY TABLE (SDK)

Gear or torque drive technology according to application-specific design.

Gear drive in swivel and rotary axes for economical 5-axes machining.

Torque motors are direct, rotary drives for highly dynamic, oscillating machining tasks.

GANTRY-CONCEPT

ALZMETALL–SPECIFIC GANTRY-KONZEPT (ASGK)
– patented –

The Gantry design:
In the gantry design, the three linear motion axes are assigned to the machine gantry. If the machine has fixed uprights with a movable crossbeam at the top, it is referred to as a bridge gantry design.

GANTRY-CONSTRUCTIONS

Conventional and modified Gantry designs

IN COMPARISON:

4-fold internal linear guides
Deviation(deflection) reduced by a factor of 2.3 and thus
- Rigidity is 2.3 times higher than “on top mounted” systems
- Less positional deviation at the tool center point (TCP) at the same level of acceleration
- Significantly increased cutting tool lifetime
