Overview
The Starrag SIP 7000 is an ultra-precision 5-axis machining center from the legendary SIP (Societe Genevoise d'Instruments de Physique) product line, now part of the Starrag Group. With X/Y/Z travels of 1,200 x 1,000 x 1,000 mm (47.2 x 39.4 x 39.4 in), the SIP 7000 is engineered for the most demanding accuracy requirements in aerospace, defense, and precision optics manufacturing. SIP machines have historically set the benchmark for jig boring and coordinate machining accuracy, and the 7000 continues that tradition with positioning accuracy in the sub-micron range.
The SIP 7000 features a thermally stabilized cast iron bed, precision ballscrews with glass scale feedback on all linear axes, and a high-precision tilting rotary table for full 5-axis simultaneous machining. Spindle speeds reach up to 20,000 RPM with an HSK-A63 interface, delivering 22 kW (30 hp) of continuous power. The rotary axes provide a B-axis swivel of +/- 105 degrees and C-axis continuous 360-degree rotation, enabling complex 5-axis contouring of turbine blades, optical housings, and precision structural components. The tool magazine holds up to 60 tools with chip-to-chip times around 5 seconds.
What sets the SIP 7000 apart from conventional 5-axis machining centers is its volumetric accuracy. While most production 5-axis machines achieve positioning accuracy of 5-8 microns, the SIP 7000 targets sub-3-micron volumetric accuracy across the full work envelope through extensive thermal compensation, precision mechanics, and active error mapping. The Heidenhain TNC 640 control provides advanced 5-axis kinematics management with built-in volumetric compensation algorithms.
The SIP 7000 competes with machines like the Yasda YBM series, Mitsui Seiki Vertex, and Dixi DHP series for ultra-precision applications. New machines are priced between $800,000 and $1,200,000 depending on configuration, reflecting the extreme engineering investment in accuracy. Used SIP 7000 machines from 2015-2022 can be found between $400,000 and $700,000, though availability is limited due to the specialized nature of these machines.

Strengths & Limitations
Strengths
- Sub-3-micron volumetric accuracy across the full work envelope sets the SIP 7000 apart from virtually all production 5-axis machining centers, enabling true jig-boring-class precision in a 5-axis platform
- SIP heritage spanning over 150 years of precision machine tool building provides proven design principles refined through decades of ultra-precision coordinate machining experience
- Extensive thermal compensation system with multiple temperature sensors and active correction algorithms maintains accuracy across long production runs and varying ambient conditions
- Heidenhain TNC 640 control with advanced volumetric compensation provides the control-side precision management that complements the mechanical accuracy of the machine structure
- 1,200 mm X-travel with 1,000 kg table load handles medium-to-large precision components including aerospace structural parts, optical housings, and defense components in a single setup
- Glass scale feedback on all linear axes eliminates ballscrew pitch error accumulation, providing direct position measurement essential for sub-micron accuracy class machines
Limitations
- At $800,000-$1,200,000, the SIP 7000 is priced significantly above conventional 5-axis machining centers, requiring applications that genuinely demand sub-3-micron accuracy to justify the investment
- 22 kW spindle power is modest compared to production 5-axis machines, reflecting the precision-first design philosophy that prioritizes accuracy over aggressive metal removal rates
- Limited dealer and service network outside of Europe and key aerospace markets can result in longer service response times and higher support costs in some regions
- Starrag's specialized market position means fewer trained operators and programmers compared to mainstream brands like DMG Mori or Mazak, potentially increasing staffing challenges

Frequently Asked Questions
01
New SIP 7000 machines typically price between $800,000 and $1,200,000 depending on spindle configuration, tool magazine size, pallet system options, and probing packages. The high price reflects the extreme engineering investment in sub-micron accuracy class machine design, including precision-ground guideways, thermal compensation systems, and volumetric error mapping. Used units from 2015-2022 can trade between $400,000 and $700,000 when available.
02
Both the SIP 7000 and Yasda YBM machines target the ultra-precision 5-axis market with sub-5-micron accuracy. The SIP 7000 offers larger travels (1,200 x 1,000 x 1,000 mm) compared to most Yasda YBM models, making it better suited for larger aerospace structural components. Yasda has a stronger presence in the Asian market and die/mold sector, while SIP has deeper roots in European aerospace and defense. Both deliver exceptional accuracy, with the choice often coming down to application size, regional support, and preferred control platform.
03
The SIP 7000 targets sub-3-micron volumetric positioning accuracy across the full work envelope, which is verified through laser interferometer calibration and ballbar testing during installation. In practice, achieving these numbers requires a temperature-controlled environment (typically 20°C ± 1°C), proper foundation isolation, and adequate warm-up time. Surface finish capabilities reach Ra 0.2 µm or better depending on material and cutting parameters.
04
The SIP 7000 can serve production roles, but it is primarily designed for precision-critical applications rather than high-volume production. Its 22 kW spindle and precision-first design philosophy favor accuracy over aggressive metal removal rates. Shops needing both high accuracy and high productivity often pair a SIP 7000 for finishing operations with a more powerful production 5-axis machine for roughing, optimizing both throughput and final part quality.
05
The SIP 7000 requires the standard maintenance of any precision CNC machining center — spindle lubrication, way lubrication, coolant management, and filter replacement — plus additional attention to the thermal compensation system sensors and environmental controls. Starrag recommends annual laser calibration verification and volumetric compensation updates to maintain stated accuracy specifications. The machine's precision guideways and ballscrews require monitoring for wear that could degrade accuracy over time.
06
The SIP 7000 is primarily equipped with the Heidenhain TNC 640 control, which is well-suited for precision 5-axis work with its advanced kinematic transformation, volumetric compensation, and conversational programming capabilities. Some configurations may offer Siemens SINUMERIK 840D sl as an alternative. The Heidenhain control is favored for its touch-probe integration, Dynamic Precision package for high-accuracy contouring, and user-friendly interface for complex 5-axis programming.
