Precise magnetic sine tables type SPNS with embedded SPNM clamping plates are processed very well and are also very precisely.
The sinusoidal basic body is hardened at 60 HRC, burnished and precision ground. You can adjust the angle through end-gauges.
SPNS sinusoidal benches are used for EDM, grinding and high precision measuring.
