How much does the CHMER RQ5030L cost?
Price estimate
We do not have a price for the CHMER RQ5030L 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 RQ5030L sits in the middle of the RQ gantry wire EDM range with 500 x 300 mm (19.7 x 11.8 in) of X and Y travel. Z remains 200 mm (7.9 in), as on the two smaller RQ machines, so the model widens the table without adding height.
It is the largest RQ frame that keeps the 60 x 60 mm (2.4 x 2.4 in) U and V axes and the ±14.5°/80 taper rating. Anyone needing a wider taper or a taller part has to move to the RQ6040L, which lists 300 mm (11.8 in) of Z. If the work is flat plate, though, the RQ5030L covers a useful area: its workpiece row reads 850 x 500 x 200 mm / 850 x 500 x 145 mm, with a 600 kg (1,323 lb) limit.
Is the gantry worth it at this size? CHMER's case rests on rigidity and on the direct drives: UX1 linear motors on X and Y, good for 1,800 mm/min (70.9 ipm), with the i8+ power supply behind the cut. U, V and Z run on AC servo motors.
The frame is a little larger than the RQ4025L at 2,500 x 2,650 x 2,250 mm (98.4 x 104.3 x 88.6 in), and weighs 3,000 kg (6,614 lb). Standard accessories include paper filters, 0.26MM diamond guides and a water chiller.

Frequently Asked Questions
01
X and Y travel are 500 mm (19.7 in) and 300 mm (11.8 in), with 200 mm (7.9 in) of Z. The workpiece size row lists 850 x 500 x 200 mm / 850 x 500 x 145 mm and the weight limit is 600 kg (1,323 lb).
02
The RQ6040L adds travel in every axis (600 x 400 x 300 mm), carries 1,000 kg (2,205 lb) and is rated for ±21°/100 taper. The RQ5030L is the smaller machine, at 3,000 kg (6,614 lb) against 4,000 kg (8,818 lb) for the RQ6040L, and suits flat work up to 200 mm tall.
03
The X Y feed rate is a maximum of 1,800 mm/min (70.9 ipm). X and Y are driven by linear motors and U, V and Z by AC servo motors. Wire feed is up to 300 mm/sec (11.8 in/sec).
04
Wire diameters of 0.15-0.3 mm (0.006-0.012 in), with 0.25 mm (0.010 in) as the standard size, at 300-2,500 gf of tension. The standard accessory list includes brass wire in DIA.0.25MM and 0.26MM diamond guides.
