CHMER CM655C

Q: How much does the CHMER CM655C cost?

The price estimate for the CHMER CM655C is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/chmer-cm655c#price; the request is passed to CHMER or an authorised dealer.

Price estimate

Uncertain

We do not have a price for the CHMER CM655C 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 CM655C is where CHMER's CNC die sinker series becomes a production mould machine. Table travel is 600 x 500 mm (23.6 x 19.7 in), ram travel 500 mm (19.7 in), and for the first time in the series all four generators are available, up to the 150N with 150 A.

The jump from the model below is large. Workpiece weight goes to 3,000 kg (6,600 lb) and electrode weight to 300 kg (660 lb). A 300 kg electrode on a 500 mm ram stroke means big graphite for deep cavities, and the 150N's maximum machining speed of 1,050 mm3/min is there to rough them. The 50N and 75N remain available where finish matters more: every generator lists 0.25 μm Ra as best surface roughness.

The table is 900 x 600 mm (35.4 x 23.6 in) in a work tank of 1,450 x 950 x 550 mm, and the ram platen is 300-800 mm (11.8-31.5 in) above the table. Dielectric volume is 1,300 L (343 gal) in the D655 tank.

Plan the installation around more than the 2,000 x 2,230 mm machine. It stands 2,685 mm (105.7 in) high and weighs 3,500 kg (7,700 lb), the 125N and 150N generators use a second cabinet, and their power input is 9 kVA and 10 kVA. Closed-loop linear scales on the three axes are standard; the tool changer and C axis are options.

Frequently Asked Questions

01 What generators can the CM655C use?

All four: 50N, 75N, 125N and 150N, with maximum machining currents of 50 A, 75 A, 125 A and 150 A. Maximum machining speed is 350, 550, 900 and 1,050 mm3/min, and maximum power input 4, 5, 9 and 10 kVA.

02 What are the load limits of the CM655C?

Maximum workpiece weight is 3,000 kg (6,600 lb) and maximum electrode weight 300 kg (660 lb). The table is 900 x 600 mm (35.4 x 23.6 in).

03 How does the CM655C differ from the CM434C?

It is a much heavier machine. The CM655C has 600 x 500 x 500 mm travels, carries 3,000 kg (6,600 lb), weighs 3,500 kg (7,700 lb) and takes generators up to 150N. The CM434C has 400 x 300 x 350 mm travels, carries 750 kg (1,653 lb), weighs 1,400 kg (3,080 lb) and is limited to the 50N and 75N.

04 What is the daylight under the ram on the CM655C?

The distance from the ram platen to the work table is 300-800 mm (11.8-31.5 in), with a ram travel of 500 mm (19.7 in). The work tank is 550 mm high.
