Overview
The Starrag SIP 5000 Series is a family of ultra-precise vertical machining centers from SIP (Société Genevoise d’Instruments de Physique), the legendary Swiss jig boring machine builder now part of the Starrag Group. The series includes the SIP 5000/6 and SIP 5000/7 models, targeting applications where positioning accuracy in the single-micron range is required.
The SIP 5000 Series carries forward SIP’s 90+ year heritage into modern 5-axis capability. With X/Y/Z travels of approximately 700 x 530 x 500 mm (27.6 x 20.9 x 19.7 in), the machines feature hydrostatic guideways on all linear axes for zero stick-slip. The natural granite bed provides superior thermal stability with roughly half the thermal expansion of cast iron.
Temperature-controlled oil circulates through the spindle, column, and bed. The motorized spindle delivers up to 20,000 RPM with HSK-A63 interface and 28 kW of power. Positioning accuracy of 0.002 mm and repeatability of 0.001 mm are verified under loaded cutting conditions. The machines run on Heidenhain TNC 640 with advanced 5-axis kinematic compensation. Tool capacity is 40 standard, expandable to 120.
New SIP 5000 Series machines price between $900,000 and $1,400,000. Competitors include the Yasda YBM Vi40, Kern Micro HD, and Mitsui Seiki PJ 303X5.

Strengths & Limitations
Strengths
- Hydrostatic guideways eliminate stick-slip and provide superior vibration damping for mirror-finish surfaces
- 0.002 mm positioning accuracy and 0.001 mm repeatability verified under loaded cutting conditions
- Natural granite bed provides exceptional thermal stability and vibration absorption
- SIP heritage dating to the 1930s means 90+ years of precision engineering refinement
- Heidenhain TNC 640 with advanced 5-axis kinematic compensation for best-in-class contouring
- Temperature-controlled oil circulation actively compensates for thermal growth
Limitations
- At $900K-$1.4M, costs 2-3x more than capable 5-axis machines from mainstream builders
- 500 kg workpiece weight and 700 mm X-travel limit the machine to small-to-medium parts
- Starrag service network is smaller than major Japanese and German builders
- Hydrostatic guideways require dedicated hydraulic system and regular oil maintenance
