EMAG CNC precision electrolytic machining application has great potential

Electrolytic processing is showing its unique charm with the rapid development of technology due to its unique non-traditional cutting processing advantages. With multi-axis linkage CNC precision electrolytic machining technology, EMAG Electrochemical Company of Germany can realize the processing of integral turbine blade and turbine blade by using electrolytic machining to completely replace high-speed milling and five-axis EDM.

Dorner has been a leader in electrolysis technology in Europe. Since 1990, the company has specialized in the production of high-quality electrolysis machine tools. In 2002, it successfully developed a precision vibration high-frequency narrow-pulse electrolysis machine and its production process. Developed the world's first multi-axis linkage CNC precision electrolysis machine. In 2009, after Dorner officially joined EMAG and changed its name to EMAG Electrochemical Machining Machine Co., Ltd., with the platform advantage of EMAG manufacturing CNC machining center, electrochemical processing technology ushered in Milestone development.

Technical strength to create high-end products

EMAG uses its platform for manufacturing CNC machine tools to upgrade multi-axis CNC precision electrolysis machine tools. It combines the technical characteristics of multi-axis linkage CNC and precision electrolytic machining. It removes metal materials based on the principle of electrochemical anode dissolution. Cutting force, no loss to the tool cathode, is particularly suitable for processing alloys in the high temperature region of the end of the compressor and difficult overall blade discs with twisted blades of titanium alloy. The five-axis EDM process of EMAG multi-axis CNC precision electrolysis machine tool can realize the electrolysis production of the whole turbine blade and turbine blades, completely replacing high-speed milling.

As a technology leader in the field of electrochemical machining, EMAG Electrochemical Machining Machine Co., Ltd., with its many patented technologies in the field, has become the world's first seven-axis CNC high-frequency narrow-pulse precision vibration electrolysis machine tool for aerospace engines. European equipment manufacturer that processes whole leaf discs. The processing process is all electrolytic, and the production efficiency is greatly improved, which effectively reduces the production cost. In addition, in the field of European diesel fuel injection system manufacturing, the electrolytic forming process of the high pressure common rail injector needle body oil return chamber is also the most used by the non-vibration electrolysis machine tool (DC or pulse power) of EMAG Electrochemical Machining Machine Co., Ltd. One of the fields.

The above two electrolysis machine tools - non-vibration electrolysis machine tools and high-frequency narrow-pulse precision vibration electrolysis machine tools - are the representative products of EMAG Electrochemical Machining Machine Co., Ltd. In Europe, EMAG is the only equipment manufacturer that can offer both types of electrolytic machines.

Successful deburring of poorly accessible parts of complex workpieces

The “deburring” has long been regarded by many as a “troublesome” that cannot be avoided. In recent years, EMAG has been successful in the development of electrochemical deburring technology, which not only fills the technical gap in the field of deburring, but also makes the overall technology of EMAG Group more perfect, thus becoming a kind of All-rounder of all cutting processes including burrs.

The unique feature of the EMAG electrochemical deburring machine is that in the electro-mechanical machine, the low-speed feed of the cathode tool is subjected to electrical discharge machining to the stationary workpiece, thereby performing electrolysis on the burr portion of the workpiece while the core is single. The power supply controls a single cathode tube (ie, multiple power supplies individually control multiple cathodes for relatively independent electrolytic processing), and cooperates with a closed cathode runner design of a professional cathode (unlike other suppliers to immerse the workpiece in the electrolytic cell for processing) Therefore, when deburring a plurality of workpieces, the machining operation of the machining parts having different processing parameters on each workpiece is performed, and the parts that do not need to be deburred can be effectively protected. While fully protecting the workpiece, EMAG electrochemical deburring machines can achieve the most economical and optimal machining accuracy, and the loss of cathode and electric energy is only 1/10 of that of competitors.

Electrochemical machining technology from EMAG Electrochemical Machining Machine Co., Ltd. can remove burrs from all complex workpieces, even for extremely tough or extremely hard parts, with excellent deburring and uniformity. Its patented 100% computer process control technology enables the machining accuracy of electrolytically machined workpieces to reach Cmk 1.67 or higher. Today, EMAG electrochemical deburring machines have been widely used for deburring of poorly accessible parts of complex shapes, such as the intersection of rear ribs, cavities, and intersecting cavities.
