How much does the CHMER RV855L cost?
Price estimate
We do not have a price for the CHMER RV855L 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
Half a metre of Z travel is what distinguishes the CHMER RV855L wire EDM. On the 800 x 500 mm (31.5 x 19.7 in) fixed-table frame of the RV series it provides 500 mm (19.7 in) of Z, and the table lists a workpiece of 1,200 x 800 x 495 mm (47.2 x 31.5 x 19.5 in). The column is headed RV855L SUBMERGED.
Cutting a section that tall under water puts demands on the generator and on flushing, and it is here that CHMER's claims for the i8 power supply are most relevant: more powerful wire-break suppression, and better heat dissipation for continuous high-speed machining. Whether a given part can be cut at full height depends on material and wire, so a test cut is the sensible basis for a purchase.
The rest of the table follows the RV853L. Load is 3,000 kg (6,614 lb), U and V travel 150 x 150 mm (5.9 x 5.9 in), and X and Y run on linear motors at up to 1,800 mm/min (70.9 ipm). The taper rating is ±21°/80mm with the wide-angle nozzle.
The tall Z raises the machine. Overall height is 2,750 mm (108.3 in), against 2,200 mm for the RV853L, and weight is 8,000 kg (17,637 lb). Check the building's clear height and the route in before ordering.
