CNC WITH SIEMENS 840DI CONTROL
ROBBI IGU HIGH PRECISION CNC INTERNAL GRINDING MACHINE WITH UPTO 4 SPINDLES |
- High Precision Internal Grinding machine
- Up to 4 grinding spindles on the rotating turret
- Motor controlled by CNC and software interpolation 2-axis allow the adjustment of various axes, customised to suit the application
- Roller linear guides
- Axis movement by means of high precision re-circulating ball screw
- Granite base
An important component of the Internal Grinding Machine IGU 400 is represented by the spindle turret that, in the maximum configuration, can be equipped with:
- 4 spindles (one of which for external)
- 4-spindles for internal grinding
- Tailstock to facilitate the grinding of a centre bore
The turret has an integrated swivel axis that runs automatically and allows you to use up to 4grinding spindles.
The rotation of the turret is automatic and the positioning is accurate and precise ( the turret do not rotates in the versions numer 1 and 2 – see spindle image)
GRANITE BASE
- Low thermal expansion
- Excellent rigidity
- Absorption of the vibrations
ROLLER LINEAR GUIDES
- Maximum rigidity
- Speed and acceleration over the very low speed
- Elimination of stick slip.
INCREMENTAL LINEAR ENCODER ON BOTH AXES
- Small coefficients of variation.
- Dampens vibrations optimally.
- No vibration side
- Maximun positioning accuracy and repeatability
- Excellent performance during the working in interpolation
