Price estimate
We do not have a price for the CHMER RV653L 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 RV653L is the smallest fixed-table wire EDM in the RV series: 600 x 500 mm (23.6 x 19.7 in) of X and Y travel, 350 mm (13.8 in) of Z and linear motors on X and Y. It weighs 7,600 kg (16,755 lb), a great deal for that travel, and the reason is the construction.
CHMER describes a high-rigidity column designed by FEA, with three large span linear guideways and a fixed table for heavy loads. Because the workpiece stays still and the column moves, the 2,000 kg (4,409 lb) load rating does not burden the axes. A block of 1,000 x 800 x 345 mm (39.4 x 31.5 x 13.6 in) can sit on the table.
The generator is CHMER's i8 power supply, for which the maker claims faster cutting (increasing 15% on 150mm workpiece) with energy saved by 20%, plus stronger wire-break suppression. An IVC regulated supply conditions unstable mains power before it reaches the cut. Machine status, utility and spare-part life can be followed from a phone or tablet through CHMER's Android app.
Feed rate on X and Y is up to 1,800 mm/min (70.9 ipm). U and V travel 150 x 150 mm (5.9 x 5.9 in), and the taper rating is ±21°/80mm with the wide-angle nozzle. CHMER also mentions its own submerged rotary table for indexing work.

Frequently Asked Questions
01
It is a fixed-table design. CHMER describes a rigid column designed by FEA and three large span linear guideways with a fixed table for heavy loads. The result is a 7,600 kg (16,755 lb) machine with 600 x 500 mm of travel that carries a 2,000 kg (4,409 lb) workpiece.
02
X 600 mm (23.6 in), Y 500 mm (19.7 in) and Z 350 mm (13.8 in). U and V travel is 150 x 150 mm (5.9 x 5.9 in). The largest workpiece is 1,000 x 800 x 345 mm (39.4 x 31.5 x 13.6 in).
03
CHMER states faster cutting speed, increasing 15% on 150mm workpiece, and energy saving of 20%, with more powerful wire break suppression. It also describes improved heat dissipation for continuous high-speed machining.
04
X and Y are driven by linear motors; U, V and Z by AC servo motors. The maximum X Y feed rate is 1,800 mm/min (70.9 ipm) and wire feed is up to 300 mm/sec (11.8 in/sec).
