The list of a wide range of national awards includes the outstanding management performance, technological innovation and good design of product etc.
We believe that without the hard work and dedication of our employees, there is no way CHMER would be such successful. The original product line consisted of Sinker, Wire Cut and Drilling EDM. Afterward the High Speed Machine was produced. Since 2018, we developed a more holistic approach, the newest products, Laser Cutting Machine and the Electrochemical Machine were released over this time. Technology is the core of CHMER. We have a staff of 40 working in our R&D division.
There are four teams here, specializing in mechanical, electrical, Mechatronics and software design. Our R&D team accounts for 15 percent of the employees in CHMER. Generally speaking, we devote 5% of our revenue to the R&D efforts and this number may even increase.
To this day, we continue to place an emphasis on research and development activities to create over 50 patents. Indeed it is their innovation that drives our company forward and sets us apart. Let’s move to the next production line. Take a look, this bright, spacious, air-conditioned production area makes the building a very pleasant workplace.
It’s also perfect for assembly of high-accuracy machines and superb product assurance. Additionally, it is so neat and tidy thanks to lean system that has been maintained by our great teams. We also implement a CPS manufacturing system. CPS can produce machines efficiently with Top-quality and shorter delivery that fully satisfy all customers’ requirements. Quality delivered is the No. 1 driver for a firm’s success.
The final stage, testing is where the product is examined to weed out any defects. Our quality control inspects carefully and does not overlook any important detail on our product. It is a critical part of the process since anything less than 100% quality guarantee will damage our reputation.

We have to say this is the most of stable AWT system in the world. The standard is set up! Through certifications of patents on RV series to perfection, we successful fulfill the customer’s need for the large mold. All the function is not only deal with the problem but also is the standard for new generation machines. We do welcome everyone to have the wonderful experience with us! Our RV series is not only designed with great appearance and highly rigid structure, but requires smart controls and a strong heart to show its perfect performance.
RV series wire cut EDM is equipped with the all new i8 +power supply. The new power cabinet has a modular PCB design, which is easy to assemble and maintain. With a DC fan to enhance the cooling performance, It can maintain a stable machine temperature at high-speeds for continuous production without PCB problems. For consistent machining accuracy a stable power supply is vital.
We build our own smart AVR power supply that uses a newly developed IVC(Intelligent voltage control) high frequency switching power supply. It provides ripple Voltage bellow 300mV and conversion efficiency above 90%. The unstable external power can be changed to high precise internal power for higher accurate machining. Innovative discharge circuit design. The discharge circuit for processing energy control transistor uses the high-current type IGBT module design. Compared with the MOSFET type before, IGBT reduces the thermal effects and transistor numbers, to save the cost in the future maintenance.
Compared with the resistor used before to consume the heat and waste the energy, The ineffective energy is now directly reused while machining. The i8+ power supply not only saves 20% of energy but also reduces indoor heat generation, This provides a stable working temperature for machining accuracy and saving energy in one time. We have the latest anti-wire break function. It estimates the thickness of the workpiece and changes the cutting data in time. The combination of software and hardware works when there is a step difference in processing to improve the machining efficiency. Setting different sparking wave forms with the processing conditions can increase the cutting efficiency on thick parts.
CHMER fully self-developed controller shows our own impressive R&D capabilities and give the commitment of after service to users. The controller includes many functions such as: 1.Pre-loaded with 50 sets of copper wire parameter selection. 2.Intelligent programming allows users to quickly start the production. 3.3999 hole data makes the multi-hole information more complete. Teaching newcomers is easier with less technical gap by our UI (User Interface) conversational operations.
Our professional R&D team provides the strongest development capabilities to customize the software and hardware for customer’s jobs. Anyone is familiar with CHMER previous products or new users can feel a significant increase in cutting speed. The new i8+ power is like the Engine of an Automobile, and how valiant of this engine? Let's go to see how it does.
Comparing to the previous G7 power supply, we can obviously to see the difference on old & new structure. With the new i8+ power supply, WIith The work conditions on a HRC55 SKD-11 steel @50mm thickness, we can opportunity to see the cutting speed stability varied from 160mm2/min up to 180mm2/min It’s a 12% efficiency improvement if compare to the G7 power supply. Same work conditions when we are doing @ 100mm thickness, we see cutting speed stability varied from 105mm2/min up to 120mm2/min, It’s a higher efficiency improvement about 15% efficiency if compare to the old G7 power supply. It’s an incredible experience to work on a high thickness Job.
We would say ''YES'' on new RV & i8+power the best match. On the RV wire cut we could get the result an excellent 3~5µm accuracy along with a good 0.55~0.65µmRa surface roughness on a thickness 30~100mm Job.
It’s almost the same to work on small size wire cut machine. Even we look at 100mm~200mm Job. it’s still a good cutting accuracy in 10um(micron meter) and just slightly reduced @0.6~0.65umRa surface roughness. Awesome.
And the most surprising thing when doing at thickness 200~400mm job , we can take a 15~19um accuracy ; just a little pity the surface roughness will down to 1.9~2.4umRa, however, It’s not bad for users actually. Let’s take a look how the reduction of outer profile error, especially from line to arc segment in NC programming path. A perfect cutting demo because the combination of hardware (linear motor plus i8+ power) and software (W5F Operation System) A smooth machining path, a small radius angle error which is perfectly be controlled in 1~2um accuracy, With a free and easy operating that we have almost forgotten RV is a giant size machine. Amazing user' experience.
We have a conclusion about radius corner error being well controlled in 3um. Just like driving a 4 wheelers (4WD) PICK-UP, which overcomes all difficult NC programming paths, what a pleasure cutting experience to operator, isn't it? We could see more proves from the cutting demons. An excellent cutting result in 3µm accuracy and surface roughness by 0.46µmRa. Another sample we could see overall features likes as (high thickness/high accuracy /high cutting speed). it’s almost forget it’s not a small wire cut machine, after all, this 'RV' is a Taiwan excellence Gold Medal awarded wire cut machine.
Let’s move it! Try it now! Challenge themselves beyond the limit. The incredible surface roughness 0.46umRa result could happen on a 30~50mm thickness Job.
The user will crush on this RV wire cut, wants to developing how the potential of this RV wire cut does. What are your waiting for? Experience it for yourself.

reaching 39.63 billion by 2024 With the data from each industry above, furthermore, we have to know the role of RV series in these industries on molds and parts processing. 80% of wire cut are used in mold manufacture including press, progressive die, plastic injection… etc. according to the design for continuous and automated mass production. For example: the oil pan, the transmission of cars, the TFT TV, fridge or air conditioner… in home appliances. Although part processing is only 20% in wire cut use, the application for it is literally no limitation.
Only the workpiece has to be electricity conductive. Of course, the cutting speed and accuracy are different from various materials and required shapes. For instance, the turbo blades in the aerospace industry and the transmission parts of energy industry. Apparently, the market for large size wire cut EDM is wide and huge; CHMER RV series will also lead the way with our customers forward!
