How much does the CHMER GLX643 cost?
Price estimate
We do not have a price for the CHMER GLX643 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 CHMER GLX643 wire EDM covers 600 x 400 x 310 mm (23.6 x 15.7 x 12.2 in) with linear motors on X and Y. It is the larger GLX model, taking workpieces up to 910 x 700 x 305 mm (35.8 x 27.6 x 12.0 in) and 650 kg (1,433 lb).
CHMER's catalogue says the U/V travel went from 100 mm to 120 mm for this model, and the table confirms 120 x 120 mm (4.7 x 4.7 in). The maximum taper angle is given as ± 21°/140 with the wide angle nozzle, which is the main functional gain over the GLX432 and its ± 21°/110 apart from sheer size.
The structure is described as FEA-optimised, with a reinforced base and slide meant to hold precision when X and Y move together. That is a sensible thing to design for on a linear motor machine, since both axes accelerate hard on contour work. Feed rate is 1,800 mm/min (70.9 ipm).
Operation follows the series. The 6th Gen AWT re-threads under water, the water shield flushes itself clean, and a 24-inch monitor with keyboard and mouse forms the operator station. Dielectric capacity is 760 L (201 gal) with a 14 L resin filter. One caution: CHMER's catalogue and its web page disagree on this model's machine dimensions and net weight, so both rows are left out of the table until the maker confirms them.

Frequently Asked Questions
01
The GLX643 has 600 x 400 x 310 mm travels, 120 x 120 mm U and V axes, a ± 21°/140 taper rating, a 650 kg (1,433 lb) load and 760 L (201 gal) of dielectric. The GLX432 has 400 x 300 x 250 mm travels, 100 x 100 mm U and V axes, ± 21°/110, 450 kg (992 lb) and 650 L (172 gal).
02
Maximum workpiece size is 910 x 700 x 305 mm (35.8 x 27.6 x 12.0 in) and maximum workpiece weight is 650 kg (1,433 lb). Z axis travel is 310 mm (12.2 in).
03
Maximum power consumption is 8 kVA. The power supply unit is a transistor circuit with no resistance loop, with rough machining, fine machining and AC-μ super fine finish discharge modes.
04
Yes. The GLX series has CHMER's 6th Gen AWT, which supports wire break and underwater threading and, with the automatic wire threading assistant device, threading of thick workpieces. CHMER states nearly 100% wire threading success.
