Starrag LX 021 vs Starrag SIP 5000
Starrag vs Starrag · 5-Axis Machining Centers
Summary
The Starrag LX 021 and Starrag SIP 5000 are both 5-axis machines from Starrag, but they serve different jobs. The LX 021 is a turbine blade machining center with a 30,000 RPM HSK-A40 (HSK-T40) spindle and 400 x 200 x 410 mm of X/Y/Z travel. The SIP 5000 is a high-precision 5-axis machine with a 20,000 RPM HSK-A63 spindle and 700 x 530 x 500 mm of travel.
The SIP 5000 carries more spindle power, 28 kW (37.5 hp) against 20 kW (27 hp), and more tools, 40 standard (up to 120 optional) against 30 in a disk magazine (up to 90). It runs a Heidenhain TNC 640, where the LX 021 uses the Siemens SINUMERIK 840D sl. The LX 021's advantage is spindle speed for small-diameter finishing of blade airfoils.

Advantages
Starrag LX 021
- 30,000 RPM spindle against 20,000 RPM
- HSK-A40 (HSK-T40) spindle aimed at compressor and turbine blades
- Siemens SINUMERIK 840D sl control, set up for automated blade cells
Starrag SIP 5000
- 700 x 530 x 500 mm of X/Y/Z travel against 400 x 200 x 410 mm
- 28 kW (37.5 hp) spindle against 20 kW (27 hp)
- 40 tools standard (up to 120 optional) against 30 (up to 90)
- Larger HSK-A63 taper against HSK-A40
Verdict
These machines answer different needs. The Starrag LX 021 is for aerospace and power generation plants producing compressor and turbine blades in volume, often in robot-loaded cells, where 30,000 RPM and a blade-specific layout matter. The Starrag SIP 5000 suits flight-critical housings, manifolds, optical and medical parts that need a larger 700 x 530 x 500 mm envelope, 28 kW and HSK-A63 tooling.
