the \"tradition\" continues to build.
Traditional processing with laser, stereo forming, plasma and water
Jet cutting in most directory lists.
The problem with these catalogues is simple: EDMing is rapidly becoming the hottest tradition in the field of cutting metals, composites and derivatives.
EDMs now replaces more \"traditional\" processing technologies every year.
Moreover, this trend continues, not only in the traditional market ---
Tooling, molding tools, mold cavity and EDM machining--
However, the EDMs sold today are usually acquired by a manufacturing workshop of a Fortune 500 company. Why?
Because EDM is now considered a highly complex production technology, it is easy to adapt to many manufacturing environments, and in addition to higher volume requirements, it is a viable alternative to other \"traditional\" processing technologies
Just a few years ago, in the US market, it was difficult to find many EDMs in certain industries or in certain applications.
But there are only a few examples of the reasons for this change: with 32-
\"Fuzzy Logic\" in V-of bit control\"
Mitsubishi EDM\'s sinker series is a new concept for EDM that adapts to today\'s era of automation and unattended.
Fuzzy logic control contains operational control rules and alternatives that automatically correct the ambiguity inherent in human reasoning and action.
Fuzzy logic control provides a processing format for automatic monitoring and adjustment to adapt to the changing discharge environment of cnc edm.
In order to always obtain the stability of the machine and the best state of the machine, fuzzylogic also integrates a high
Speed arc avoidance function provided by special arc detection circuit. Fuzzy-
The processing conditions are monitored logically and accurately, and the optimal processing conditions are always maintained through automatic control.
The speed of these two abilities
Simplify the overall processing.
A series of fans
Jet engine blades are now being manufactured in 11 steps instead of 37 thanks to EDM.
EDM enables the company to solve the following problemsthe-
In some cases, the clock accounts for 86% of unattended time.
It is responsible for increasing production and saving, both of which contribute to greater profit margins.
Newly designed workpiece grabbing and positioning device, plus up to 72 tools
A replacement magazine is installed in sinkerapplication, thus turning a single unit into a virtual machining center for the production and operation of electronic parts.
EDM has successfully burned a sandwich material made of exotic alloys and thermoplastic resin, enabling it to be used in aircraft design.
In many applications, acid etching technology is replaced by precision EDM.
Line EDM sales increased significantly due to new line feeder, power supply, reverse power supply
Independent uv-electrolytic power supply
Shaft capability and significantly improved servo
These yield accuracy, repeatability and reliability are unmatched by any other technology
Growing market segments throughout the machining market.
With improved EDMing accuracy, coupled with its flexible cutting capabilities, the technology is moving into more markets than ever before, more production plans and more material cutting applications
EDMing is really developing his own tradition.

Equipment for laser cutting, drilling and welding.

The CNC production laser system is designed to compete directly with conventional turret punch machines.
The system uses double cut and a new dynamic punch technology, providing advanced technology in precision sheet metal manufacturing throughput.
The laser system processes 4 ftx 8 ft pieces and uses a 1500 W laser cavity.
The machine is designed for the processing of stainless steel and aluminum plates without marking, thus eliminating the need for expensive PVC protective materials.
Dynamic piercings allow \"dynamic\" piercings when the workpiece moves towards the cutting line.
The programmer specifies the geometry of the hole.
The rest is done by the system, using spiral leads-in (or path)tothe cut.
The axe never stops;
The electronic shutter closes the laser that it moves from one hole to another.

Including four working envelopes, each with a choice of two laser power levels, the machine is designed for cutting stainless steel, hot-rolled and cold-rolled steel, as well as galvanized steel, aluminum, titanium, Harbin alloy, acrylic plastic, composite and alloy.
The system controller adopts the fast replacement mechanism;
Remove the laser head and replace it with a stylus probe.
The operator moves the probe around the part through the ateching pendant and joystick to digitize the part.
The controller processes these reference points as well as path information, such as circles, arcs, curves, etc. , which are input by the operator to program the correct cutting path.
Other features include quick traverse rate manual coverage, background editing and programming, patented nozzle design to eliminate electrical interference, and system diagnostics.
