Engineering Success
Grinding small, high precise diameters concentrical to a hole
- Concentricity between outside diameter and hole below 3µm
- Diameter tolerance below 3µm
- Roundness below 1µm
- Part diameter down to 20µm
- Length to diameter ratio 10/1
- 100% fully automatic inspection in production process
- Closed loop production for high process stability in high volume production
Grinding difficult, small geometries in high precision
- Diameter tolerance in 2µm
- Difficult geometries
- Ultra fine surface quality
- Length to diameter ratio more than 10/1
Exceeding Customer Expectations - Ceramic Nozzle
Our customer pursued electro-formed gold, believing it was their only option, But partnering with SPT resulted in a CIM zirconia nozzle that outperforms the gold nozzle in all aspects
- Full component characterization, including flow testing.
- OD: +/- 0.003mm
- Orifice:
Size 0.070 +/- 0.0025mm
Concentric < 0.010mm
Circularity < 0.0025mm
Process Stability
- Optimizing production processes to guarantee for the most process stability.
- Developing and building atomatic production machines, handling systems and inspection systems for the parts.
