Overview
The Starrag SIP 7000 Series is a family of ultra-precise horizontal machining centers from the legendary SIP brand, now part of the Starrag Group. The series includes the SIP 7000/7 4A and SIP 7000/7 5A models, designed for horizontal-spindle machining with sub-3-micron volumetric accuracy.
The horizontal spindle orientation provides advantages for specific applications: gravity-assisted chip evacuation, better multi-sided workpiece access on rotary tables, and favorable thermal behavior. X/Y/Z travels of approximately 1,200 x 1,000 x 1,000 mm handle medium-to-large precision components.
The 7000/7 4A provides 4-axis capability while the 7000/7 5A adds full 5-axis simultaneous machining. Both feature thermally stabilized construction, precision ballscrews with glass scale feedback, and extensive thermal compensation. The spindle delivers up to 20,000 RPM with HSK-A63 and 22 kW continuous power.
Sub-3-micron volumetric accuracy is verified through laser interferometer calibration. The Heidenhain TNC 640 control provides advanced volumetric compensation. New machines price between $800,000 and $1,300,000. Competitors include the Yasda YBM H-series, Mitsui Seiki Vertex, and Dixi DHP.

Strengths & Limitations
Strengths
- Horizontal spindle provides natural chip evacuation and better multi-sided workpiece access
- Sub-3-micron volumetric accuracy exceeds most horizontal machining centers
- Both 4-axis and 5-axis configurations available
- 1,200 mm X-travel with 1,000 kg table load handles medium-to-large precision components
- Glass scale feedback eliminates ballscrew pitch error accumulation
- SIP heritage spanning 90+ years of proven ultra-precision design
Limitations
- $800K-$1.3M premium justified only for applications requiring sub-3-micron accuracy
- 22 kW spindle power prioritizes accuracy over aggressive metal removal
- Limited service network outside Europe and key aerospace markets
- Fewer trained operators available compared to mainstream HMC brands
