Starrag SIP 5000 vs Starrag SIP 7000
Starrag vs Starrag · 5-Axis Machining Centers
Summary
The Starrag SIP 5000 and Starrag SIP 7000 are high-precision 5-axis machining centers that share a 20,000 RPM HSK-A63 spindle and a Heidenhain TNC 640 control. The SIP 7000 is the bigger machine: 1,200 x 1,000 x 1,000 mm of X/Y/Z travel against 700 x 530 x 500 mm, an 800 x 800 mm table against 630 x 500 mm, and a 1,000 kg (2,205 lb) load against 500 kg (1,102 lb).
The SIP 7000 also carries 60 tools against 40 standard (up to 120 optional). The SIP 5000 has the stronger spindle, 28 kW (37.5 hp) against 22 kW (30 hp), and is the lighter machine at 14,000 kg against 18,000 kg. Starrag quotes 0.002 mm positioning for the SIP 5000 and < 3 µm volumetric for the SIP 7000, which are different measures.

Advantages
Starrag SIP 5000
- 28 kW (37.5 hp) spindle against 22 kW (30 hp)
- Tool capacity up to 120 optional
- Lighter at 14,000 kg (30,865 lb) against 18,000 kg (39,683 lb)
Starrag SIP 7000
- 1,200 x 1,000 x 1,000 mm of X/Y/Z travel against 700 x 530 x 500 mm
- 800 x 800 mm table and 1,000 kg (2,205 lb) load against 630 x 500 mm and 500 kg
- 60 tools standard against 40
Verdict
Both are built for jig-boring-class accuracy, so the decision is envelope. The Starrag SIP 5000 suits aerospace housings, optical parts, implants and mold inserts that fit a 630 x 500 mm table and 500 kg, with 28 kW for harder materials. The Starrag SIP 7000 is for larger guidance housings, blisks, gimbal parts and optical mounts that need 1,200 mm of X travel, a 1,000 kg load and 60 tools.
