1.Smoothing of milled surfaces
2.Surface hardening (cold)
3.Targeted localized reduction of residual stresses
Advantages / Benefits
Longer service life of machined surfaces
Increased economic efficiency
Elimination / reduction of manual machining time
Ra roughness improved by 2-20 times (Ra <0.05 µm)
Homogeneous surface quality
Repeatable surface quality
No offset (machining allowance) required due to μ-deformation
Cold hardening of surfaces
Increase of surface hardness by more than 30% due to riveting (depending on material)
Compressive stresses up to 1,000 MPa up to a depth of 0.5 mm
Hardness increase of more than 10% possible
Targeted localized reduction of residual stresses
Increased service life by preventing premature wear of the working surfaces
Milling + machine polishing on the same machine (no re-fixturing of the part)
When polishing, the inclination angle should be α <30°
The direction of tool movement must correspond to the geometry of the component
5-axis machining is preferred, depending on the geometry of the surface to be machined.
The FORGEfix system must not rotate during machining (especially with external air supply).
- Machining of the corresponding NC program with S = 0 rpm.
The material in the machining zone must be homogeneous, with the same physical and mechanical properties.
- Polishing inhomogeneous material results in a surface with different characteristics.
An appropriate surface quality / flatness is required.
- Surface flatness cannot be smoothed by polishing.
80-100% reduction of manual work such as grinding, polishing, finishing, lapping.
Up to 100% of the manual process can be fully automated
Finishing time and overall production time is reduced
Lower requirements on the quality of the resulting surface after milling, reducing machine time
Process repeatability
Complete machining in one clamping of the workpiece is possible.
Strengths / Advantages
Savings on machining time
Optimal utilization of equipment
Reduction of human resources
Improved quality
