How much does the AWEA LG-4030 cost?
Price estimate
We do not have a price for the AWEA LG-4030 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The AWEA LG-4030 is the shortest machine in the LG gantry line: a 5-face machining center with 4,000 mm (157.5 in) of X travel, 3,000 mm (118.1 in) of Y and 1,000 mm (39.4 in) of Z over a fixed 4,000 x 2,800 mm (157.5 x 110.2 in) table. The table does not move. The gantry travels along it, which is why AWEA rates the load per area, 2,500 kg/m², instead of as a single weight.
Being the shortest has a measurable benefit. X-axis positioning accuracy under VDI is P = 0.025 mm, the same figure the table gives for Y and Z, and repeatability is Ps = 0.018 mm. Every longer LG gives up some of that: the LG-5030 is listed at P = 0.030 mm and Ps = 0.022 mm. On this size the gantry is moved by 2 sets of large ball screws with servo motors and optical linear scales under simultaneous servo control.
X rapid traverse is 12 m/min (472 ipm), with 15 m/min (591 ipm) on Y and 10 m/min (394 ipm) on Z. The standard spindle is a CAT50 gear unit at 4,000 rpm with a 22 / 26 kW (30 / 35 HP) motor, and AWEA quotes 982 Nm at 253 rpm for it. Gear spindles of 5,000 / 6,000 rpm and built-in spindles of 6,000 / 8,000 rpm are options.
Five-face work depends on the milling heads, and those are not part of the base machine. AWEA says the LG series could be equipped with an automatic head changer and a vertical / horizontal ATC system; the angle, extension and universal heads are the maker's own. The floor type magazine behind the machine holds 32 tools up to 350 mm (13.8 in) long and 20 kg (44 lb).

Strengths & Limitations
Strengths
- Tightest X accuracy of the LG range under VDI: P = 0.025 mm positioning and Ps = 0.018 mm repeatability
- Fixed 4,000 x 2,800 mm (157.5 x 110.2 in) table rated at 2,500 kg/m², so the part's weight never rides on a moving axis
- Standard 4,000 rpm gear spindle delivers 982 Nm at 253 rpm from a 26 kW (35 HP) motor
- Twin ball screws with optical linear scales on X, driven under simultaneous servo control
- 3,800 mm between the columns (3,500 mm with the water eliminator) over a 2,800 mm wide table
Limitations
- X rapid of 12 m/min (472 ipm); the LG-6030 with its rack and pinion drive is listed at 20 m/min (787 ipm)
- Milling heads, the automatic head changer and the horizontal ATC are equipment the machine could be fitted with, not rows of the standard specification
- The specification shows a 32-tool magazine and no larger option for this size
- Z travel is 1,000 mm (39.4 in) on every LG, whatever the X and Y
- Needs an 80 kVA supply even at the smallest size

Frequently Asked Questions
01
Because the table is fixed and the gantry moves over it. AWEA rates the 4,000 x 2,800 mm (157.5 x 110.2 in) table at 2,500 kg/m² and describes a double layer table that attaches firmly to the base. What has to be checked for a given job is how the workpiece weight is spread over its footprint, not one total figure.
02
With 2 sets of large size ball screws, servo motors and optical linear scales, driven by simultaneous servo control. AWEA uses this arrangement on the LG sizes with 4 m and 5 m of X travel. From the LG-6030 upward the gantry runs on a rack and pinion instead, and the X rapid rises from this machine's 12 m/min (472 ipm) to 20 m/min (787 ipm).
03
Under VDI, positioning is P = 0.025 mm on X and P = 0.025 mm over full travel on Y and Z. Repeatability is Ps = 0.018 mm, with Ps = 0.020 mm for Y and Z. The JIS rows read ± 0.025 over full travel for positioning and ± 0.003 mm for repeatability.
04
The standard unit is a 4,000 rpm gear spindle with a 2-speed gearbox, CAT50 taper and a 22 / 26 kW (30 / 35 HP) motor. Options are gear spindles of 5,000 / 6,000 rpm and built-in motor spindles of 6,000 / 8,000 rpm. AWEA gives the built-in spindles a maximum of 600 Nm at 350 rpm, against 982 Nm at 253 rpm for the standard gear spindle.
