GRAUX is equipped with a new large milling machine

19 December 2019

A new SORALUCE FP 8000 milling machine is operational.

In October 2019, GRAUX started up a new milling machine with large dimensional capacity, more precise and autonomous. This equipment completes the upgrade of the entire production tool and thus meets the growing demand for the manufacture of large mechanically welded units.

Hosting a 26-ton machine in a working workshop presents many challenges.

The installation of this new machining set required careful preparation. The pursuit of activities in the hall intended to accommodate this machine should not be compromised while reorganizing the work areas in order to free up space for carrying out the important work necessary for the preparation of the slab. All this in a busy production planning period! The team was flexible and fully participated in the smooth arrival of this new ‘baby’.

The demolition of the concrete slab, the excavation and the clearing of 240 m3 of earth were completed at the end of May 2019. Then, during the month of June, specific reinforcement was carried out, the pouring of a concrete high resistance and the very precise production of the machine anchoring studs.

When August resumed, following the official summer closing, the milling machine was installed. After this work, which lasted six weeks, the first machine adjustments were able to start at the end of September. The final acceptance took place in early October.

Technical information of the milling machine.

Observed tolerances measurements upon receipt of the machine.

The machine was received in our workshops with the following measures:

  • Machine geometry accuracy according to ISO 10791-3:
    • X axis: 0.022 mm on the 8000mm
    • Y axis: 0.005 mm
    • Z axis: 0.02 mm
  • Head accuracy according to ISO 10791-3:
    • Spindle nose: 0.005mm
    • Spindle axis relative to the table: 0.004mm
    • Head rotation: 0.01mm

A new machine geared towards the needs of demanding customers.

This milling machine ideally complements all of our production tools. It allows us to respond, in particular, to specific needs both in terms of large machining dimensions and high production dynamics.

Here are its main advantages:

  • More capacity in terms of dimension;
  • Greater precision;
  • Machining in full autonomy (without permanent operator) thanks to the 40 tools cassette;
  • High spindle speed allowing better surface finish and faster machining of aluminum;
  • Perfect for machining large dimension welds.
