How much does the CHMER RX853F cost?
Price estimate
We do not have a price for the CHMER RX853F 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
A 2,000 kg (4,409 lb) workpiece rating on an 800 x 500 mm (31.5 x 19.7 in) cutting area is the headline of the CHMER RX853F wire EDM. It is the heavy-load, small-tank version of the 853 frame in the RX series, with a 340 L (90 gal) tank and a footprint of 2,400 x 2,800 mm (94.5 x 110.2 in).
The RX853S, by comparison, carries half the weight, 1,000 kg (2,205 lb), and occupies 3,150 x 3,500 mm of floor around a 1,370 L (362 gal) tank. For a shop cutting dense mould steel in a tight bay, the RX853F fits where the RX853S would not, and it weighs slightly less at 5,460 kg (12,037 lb).
Z travel is 300 mm (11.8 in) and the listed workpiece envelope is 1,210 x 800 x 295 mm (47.6 x 31.5 x 11.6 in). Taper is rated ±21°/140 with a wide-angled nozzle, using 150 x 150 mm (5.9 x 5.9 in) of U and V travel. The wire system is the common one across CHMER's servo-driven machines: 0.15-0.3 mm wire, 300 mm/sec maximum feed and 300-2,500 gf of tension.
Two paper filters are standard here, one fewer than on the RX853S. A swinging panel, two 2T chillers and auto data recovery after a blackout are also included. Wire threading is not automatic unless the AWT option is ordered.

Strengths & Limitations
Strengths
- 2,000 kg (4,409 lb) maximum workpiece weight on 800 x 500 mm (31.5 x 19.7 in) of travel
- Footprint of 2,400 x 2,800 x 2,350 mm (94.5 x 110.2 x 92.5 in), smaller than the RX853S
- ±21°/140 taper rating with 150 x 150 mm (5.9 x 5.9 in) U and V axes
- 340 L (90 gal) tank keeps the water volume to treat and chill low
- Swinging panel is standard on the RX series
Limitations
- 340 L (90 gal) tank against 1,370 L (362 gal) on the RX853S
- Auto Wire Threading (AWT) is an option
- X Y feed rate is capped at 800 mm/min (31.5 ipm)
- Machine weight of 5,460 kg (12,037 lb) plus a 2,000 kg part calls for a floor check

Frequently Asked Questions
01
The maximum workpiece weight is 2,000 kg (4,409 lb), double the 1,000 kg (2,205 lb) of the RX853S. The maximum workpiece size is 1,210 x 800 x 295 mm (47.6 x 31.5 x 11.6 in).
02
Outside dimensions are 2,400 x 2,800 x 2,350 mm (94.5 x 110.2 x 92.5 in), width by depth by height. The machine weighs 5,460 kg (12,037 lb) before water and workpiece are added.
03
No. The axis drive system is listed as AC Servo Motor, and the X Y feed rate is a maximum of 800 mm/min (31.5 ipm). Wire feed runs at up to 300 mm/sec (11.8 in/sec).
04
Two paper filters, diamond guides, upper and lower flushing nozzles, energizing carbides, brass wire, an alignment jig, ion exchange resins for the flushing and submerged circuits, a swinging panel, auto data recovery after a blackout and two 2T water chillers. AWT, the wire feeder, the wire chopper and a DC inverter chiller are options.
