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 051 is a horizontal-spindle machining center for simultaneous 5-axis work, with a tilting B-axis and a rotary C-axis. Starrag's page for the model gives few numbers, and the ones it does give describe the spindle and the axis speed: an HSK-A63 taper, 30 kW (40 HP) continuous power and 40 m/min (1,575 IPM) rapid traverse.

Thirty kilowatts of continuous power at an HSK-A63 interface is a rating that supports roughing as well as finishing. It sits well above the 20 kW (27 hp) of the smaller LX 021, which runs an HSK-A40 (HSK-T40) taper. The spindle also carries displacement and temperature sensors. Sensors of that kind are there to follow how the spindle grows as it warms, which matters when a long 5-axis finishing cut has to hold position from the first pass to the last.

What the page leaves out is as relevant to a buyer as what it states. Travels, maximum spindle speed, torque and tool magazine size are all missing from the listed figures, so the working envelope and the speed range have to come from Starrag's quotation for the specific machine.

Frequently Asked Questions

01 What spindle does the LX 051 have?

A horizontal spindle with an HSK-A63 taper and 30 kW (40 HP) continuous power, fitted with displacement and temperature sensors. Starrag's page for the model gives no maximum speed or torque, so those two figures need to be requested.

02 Which axes does the LX 051 use for 5-axis machining?

A tilting B-axis and a rotary C-axis, listed for simultaneous 5-axis machining, with the spindle horizontal. Rapid traverse is 40 m/min (1,575 IPM).

03 How does the LX 051 compare with the LX 021?

The LX 051 has the larger spindle interface and more power: HSK-A63 and 30 kW (40 HP) continuous, against HSK-A40 (HSK-T40) and 20 kW (27 hp) on the LX 021. The LX 021 is listed with travels of 400 mm (15.75 in), 200 mm (7.87 in) and 410 mm (16.14 in) and a 30,000 RPM spindle. Starrag's page for the LX 051 gives no travels or maximum speed to set beside those.
