How much does the CHMER CM434C cost?
Price estimate
We do not have a price for the CHMER CM434C 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 CM434C is a CNC die sinker EDM with 400 x 300 mm (15.7 x 11.8 in) of table travel and 350 mm (13.8 in) of ram travel. It is the second size in CHMER's CNC series and the last one before the frames get much heavier: at 1,400 kg (3,080 lb) it is still a machine that goes into an ordinary toolroom bay.
Its table measures 650 x 400 mm and sits in a 1,050 x 630 x 350 mm (41.3 x 24.8 x 13.8 in) work tank. Workpieces up to 750 kg (1,653 lb) are allowed. Against the CM323C that is half as much load again, with a longer ram travel for deeper cavities; the CM323C has a 300 mm ram travel.
As on the smaller model, generators are limited to the 50N and 75N. With the 75N the machine delivers 75 A and a maximum machining speed of 550 mm3/min from a 5 kVA input. Both generators list 0.2% electrode wear and a best surface roughness of 0.25 μm Ra.
Construction follows the series: stress-relieved cast iron, precision ball screws on X, Y and Z, linear motion guides and closed-loop linear scales. The D434 dielectric tank holds 390 L (103 gal). One gap in the published data: CHMER's metric and pound figures for the maximum electrode weight do not agree for this model, so that row is omitted.
