How much does the CHMER RX853S cost?
Price estimate
We do not have a price for the CHMER RX853S 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 RX853S is a large-format wire EDM with 800 x 500 mm (31.5 x 19.7 in) of X and Y travel, 300 mm (11.8 in) of Z and a 1,370 L (362 gal) tank. CHMER describes the RX series as suitable for wire cutting of large-sized molds and machined parts, and names large home appliance and automotive mould work as its intended use.
The tank is the figure that defines this variant. The RX853F has the same travels but a 340 L (90 gal) tank, and it is rated for a 2,000 kg (4,409 lb) workpiece where the RX853S is rated for 1,000 kg (2,205 lb). So the choice between the two is a choice between water volume and load. The footprint follows: the RX853S measures 3,150 x 3,500 x 2,350 mm (124.0 x 137.8 x 92.5 in) and weighs 5,535 kg (12,202 lb).
Maximum workpiece size is 1,210 x 800 x 295 mm (47.6 x 31.5 x 11.6 in). U and V travel of 150 x 150 mm (5.9 x 5.9 in) supports a taper rating of ±21°/140 with the wide-angled nozzle, a taller taper band than the G series offers. Drives are AC servo motors at up to 800 mm/min (31.5 ipm).
Three paper filters, a swinging panel and 2T water chillers on both circuits are standard. Auto Wire Threading (AWT) is optional, which matters on a machine whose jobs can run for many hours.

Strengths & Limitations
Strengths
- 800 x 500 x 300 mm (31.5 x 19.7 x 11.8 in) travels for large mould plates
- 1,370 L (362 gal) tank, about four times the 340 L (90 gal) of the RX853F
- ±21°/140 taper rating on 150 x 150 mm (5.9 x 5.9 in) of U and V travel
- Swinging panel and two 2T water chillers are standard accessories
- Takes workpieces up to 1,210 x 800 x 295 mm (47.6 x 31.5 x 11.6 in)
Limitations
- Workpiece limit of 1,000 kg (2,205 lb) is half the 2,000 kg (4,409 lb) of the RX853F
- Large footprint: 3,150 x 3,500 mm (124.0 x 137.8 in) of floor
- AWT, the 30kgs wire feeder and the wire chopper are options
- AC servo drives limited to 800 mm/min (31.5 ipm)

Frequently Asked Questions
01
Tank, load and footprint. The RX853S has a 1,370 L (362 gal) tank, a 1,000 kg (2,205 lb) workpiece limit and outside dimensions of 3,150 x 3,500 x 2,350 mm. The RX853F has a 340 L (90 gal) tank, a 2,000 kg (4,409 lb) limit and measures 2,400 x 2,800 x 2,350 mm. Travels are identical.
02
CHMER lists 1,210 x 800 x 295 mm (47.6 x 31.5 x 11.6 in) and 1,000 kg (2,205 lb). The wire covers 800 x 500 mm (31.5 x 19.7 in) of that in X and Y, with 300 mm (11.8 in) of Z travel.
03
The table gives ±21°/140 using a wide-angled nozzle (DA+DB=15mm). U and V axis travel is 150 x 150 mm (5.9 x 5.9 in), which is what allows the wide angle to be held over a tall section.
04
Machine weight is 5,535 kg (12,202 lb). With 1,370 L (362 gal) of water in the tank and a workpiece of up to 1,000 kg (2,205 lb), the loaded machine is considerably heavier, so check the floor before installation.
