GROB G640 4 Axis Pallet changer Milling machine

Detailed Specification

The 4-axis universal machining centers G440, G640 and G840 offer our customers a heavy-duty machine series that guarantees robust and optimal, dynamic processes at the same time.

GROB 4-axis machine series is characterized by high productivity, reliable components and unique resilience. Thanks to extensive configuration options, our machining centers can be ideally adapted to the requirements of your production.


Topology optimization for a perfect combination between stability, cushioning and weight.

Thanks to the different motor spindle types (HSK, SK, BIG-PLUS), you have a wide range of options to find the optimal solution for your machining

Depending on the equipment, the drive concept is based on up to two symmetrically arranged ball screws in the Y-axis. The built-in torque motor in the B-axis also enables fast positioning with the highest precision.

Optimally designed Tool Center Point (TCP) ensures particularly stable processes and high cutting performance.

Our efficient machine cooling concept includes the cooling of the drive train, control cabinet, motor spindle, rotary table and cooling lubricant system, which means that a high level of precision is achieved on the component


The largest possible workpiece in the work area can be machined with the maximum tool length (up to 830 mm)

Choice of a wide variety of tool magazine variants in different sizes (up to 450 spaces). These have a modular structure and can also be exchanged afterwards using “Plug and Play”.

The chip conveyor can be designed for your different machining processes and is suitable for a wide variety of materials

The cooling lubricant system is available in different packages and ensures a chip-free work area and a stable process. The optionally available IKZ with up to 120 bar rounds off the various additional options.
