Our best estimate for a 5-axis machining center in this class — not a quote from Starrag. Configuration moves it a long way.

Overview

The Starrag LX 451 is a large blade machining center: the listed figures give a maximum blade length of about 1,200 mm (47.2 in) inside travels of 1,500 mm (59.1 in) in X, 1,000 mm (39.4 in) in Y and 1,200 mm (47.2 in) in Z. An A-axis and a B-axis provide simultaneous 5-axis motion. Starrag's current product pages do not show this model, so the table here is unconfirmed and worth checking against the machine's own documents.

The size becomes clear next to the small end of the family. The LX 021 has travels of 400 mm (15.75 in), 200 mm (7.87 in) and 410 mm (16.14 in) and a 30,000 RPM spindle with 20 kW (27 hp). The LX 451 gives up spindle speed for reach and power: 18,000 RPM, 35 kW (47 HP) and an HSK-A63 taper.

Long blades are finished with long tool paths, and over that distance the accuracy rows are the ones that count. Positioning accuracy is listed at +/-0.005 mm (+/-0.0002 in), repeatability at +/-0.002 mm (+/-0.00008 in) and surface finish capability at Ra < 0.6 um. The magazine holds 60 tools as standard, with 120 optional, and the control is a Siemens SINUMERIK 840D sl. Torque, rapid traverse and machine weight are absent from the table, so roughing capacity and installation requirements have to be asked for.

Strengths & Limitations

Strengths

Takes blades up to about 1,200 mm (47.2 in) long, with 1,500 mm (59.1 in) of X travel
18,000 RPM spindle on an HSK-A63 taper with 35 kW (47 HP)
Listed positioning accuracy of +/-0.005 mm (+/-0.0002 in) and repeatability of +/-0.002 mm (+/-0.00008 in)
Surface finish capability listed at Ra < 0.6 um
60 tools as standard, 120 optional

Limitations

The larger 120-tool magazine is an option, not part of the standard machine
No spindle torque figure is listed, so heavy roughing capacity cannot be judged from the table
Not on Starrag's current product pages; rapid traverse and machine weight are not among the listed figures

Best For

Long blades up to about 1,200 mm (47.2 in) Simultaneous 5-axis aerofoil finishing to a listed Ra < 0.6 um Blade work needing far more reach than the 400 mm (15.75 in) X travel of the LX 021

Frequently Asked Questions

01 What is the longest blade the LX 451 can machine?

The listed maximum blade length is about 1,200 mm (47.2 in). The travels are 1,500 mm (59.1 in) in X, 1,000 mm (39.4 in) in Y and 1,200 mm (47.2 in) in Z, with an A-axis and a B-axis for simultaneous 5-axis machining.

02 What spindle is listed for the LX 451?

An 18,000 RPM spindle with an HSK-A63 taper and 35 kW (47 HP). No torque figure is listed, so ask for the torque curve before planning heavy roughing passes on the machine.

03 How accurate is the LX 451?

The listed positioning accuracy is +/-0.005 mm (+/-0.0002 in) and the repeatability +/-0.002 mm (+/-0.00008 in). Surface finish capability is listed at Ra < 0.6 um. No current Starrag page confirms these figures.

04 How does the LX 451 compare with the LX 021?

The LX 021 is the small machine of the family, with 400 mm (15.75 in) of X travel, a 30,000 RPM spindle, 20 kW (27 hp) and an HSK-A40 (HSK-T40) taper. The LX 451 has 1,500 mm (59.1 in) of X travel, runs to 18,000 RPM with 35 kW (47 HP) and uses HSK-A63.
