The CHMER 434C is the product of decades of experience building EDM machine tools. It is a space-
efficient three-piece design comprised of the machine tool, DI tank, and CNC control.
• X, Y, and Z fully closed-loop Glass Scale feedback with .000020” (.0005mm) resolution
• Ultra-high precision ball crews and LM Guides (ways)
• Panasonic AC motors on all three axes
• Remote control
• Flushing Manifold with pressure and suction flush valves
• Auto lube system
• Halogen Work light
All features listed above are standard equipment on the CHMER CM434C
Construction
The casting is a very rigid design in order to ensure longevity, stability, and offset the effects of
temperature fluctuation.
Remote control
Provided as standard equipment, the remote allows the operator to perform operations such as jog,
edge find, Macro Chuck open/close, tank fill and drain, program start and stop, and more.
Auto lube system
The machine is equipped with an Auto Lube system that is pre-programmed to deliver the correct
amount of lubricant at the correct intervals to all necessary parts of the machine.
CNC Control – Power Supply Features
• Advanced Anti-Arc protection
• Extremely user friendly
• Conversational Programming
• Auto cutting condition selection
• More than 75 preprogrammed orbit routines
• Fast cutting – 1.35 in3/hr with 50N power supply
• Best wear rate – 0.2%
• Best surface finish – 0.25 μm/Ra
• Six-axis capable
• Industrial-grade PC with dual Intel Pentium processors
• LAN port
• USB Port
• 15” Color TFT
The CHMER control with its intuitive conversational programming is very easy to use. The power
supply is simple to manage. Of course, power selections are chosen automatically by the control. The
operator simply inputs the following:
Depth of cut
Electrode material and work piece material
Surface area of cut
Wear rate
Desired Surface Finish
The control does the rest, changing power settings and orbits at the appropriate times in the burn to
allow for electrode wear and achieve the desired surface finish in the shortest possible burn time. It
provides the operator with optimum spark gap info, so there is no guessing about how far undersize to
make the electrode. All parameters are easily edited. This is especially helpful when cutting exotic
materials.
There are many canned cycles built into the control such as edge find, center find, etc. which allow
extremely fast setup. It is six-axis capable (axes other than X, Y, and Z are available at additional
cost). Several choices are offered for communicating with the control, such as LAN port, USB Port,
and MDI. It is powered by an industrial-grade PC with dual Intel Pentium processors.
