Like its sister systems in the MFP series, the Mägerle Grinding Center delivers superb results for creep feed grinding with high removal capacities as well as for profile and flat grinding. In its swivelling table version, the MGC is also designed with the maximum ejection capacity. The 180° swivelling table allows loading and unloading of workpieces while machining is in operation. Non-productive times for workpiece change are thus largely eliminated. This results in maximum productivity for small and large batches, as well as in special applications. The MGC with swivelling table, in conjunction with the automatic loading and unloading system, frees up additional reserves. The openly accessible swivelling table also provides the ideal interface.
Applications:
- Turbine rotor vane
- Rotors
- Pump rotors
- Rocker arm
- Spring collets
- Steering rack variations
- Projectile body
- Shearing knife
- Textile industry
- Saw blades
