Request offer You have questions or need detailed information? ME Mechanical Team https: The abrasive grits protruding from the grinding dfburring at the contact with the workpart establish the gap distance. Instead of cutting metal using hardened tooling, material is removed more efficiently by an electrochemical process.

Workpieces with complex geometries often contain machining sectors that are difficult to get at. ECM is a highly productive process.

Wear-resistant, precise, contactless and economical are all predicates that apply to the ECM deburring process. Learn how your comment data is processed. Only then will it be deburriny to remove burrs economically and with precision.

Less material is removed in the Electrochemical Deburring ECD machining process; cycle times are much shorter. Electrochemical flectrochemical ECG is a particular type of Electrochemical Machining in which a rotating grinding wheel with a conductive bond material is used to augment the anodic dissolution of the metal workpart surface, as illustrated in the below figure 2.

Another difficulty in practical applications is the so called “”secondary burr””, i. The ECM process is highly stable with very good process control which ensures accuracy, quality, consistency and the highest repeatability. In the case of the EMAG Group, machining, automation and deburring electroochemical all covered by their firmly established technologies.



The mechanical machining and deburring of pump housings is currently considered state-of-the-art. The electrode tool is designed better to focus the metal removal action on the burr. ECM is an ideal deburring process for parts where burrs are difficult to reach or machine using conventional methods, and deburriing eliminates the challenge of secondary burr formation. Deburring does not count as a core process in machining. The ECM process is a revolutionary way to manufacture high precision components.

Electrochemical deburring ECD is an adaptation of Electrochemical Machining ECM process designed to remove burrs or to round sharp corners on metal workpieces by anodic dissolution method. Advantages of this process include:. As cycle times and output rates can be scaled using different degrees deburfing parallelisation – i. Providing short circuit detection at drburring DC source.

Trust our experts to manage these key deburrinv considerations: One example of a demanding deburring task is to be found in the elecrochemical of pump housings for common-rail systems. Abrasives materials used in ECG include aluminum oxide and diamond. This makes ECM ideal for the following surface machining applications: Dear Sir, We are looking for purchase electrochemical deburing machine, kindly contact us. Removes burrs at bore exits and at intersecting holes in a workpiece caused by conventional drilling.

Ensuring the cathode is made out of electrically conductive materials. ECM deburring of a pump housing for common-rail systems.

Using the electro-chemical deburring process instead of conventional deburring methods mechanical or water jet deburring has reduced costs quite significantly and made it possible to match the cycle time to the start-up and production phase by scaling the electro-chemical deburring process to suit the desired output rate. Our team of manufacturing professionals will work with you to determine the best possible tooling design for your project. Controlling the gap by designing the appropriate fixtures including cathodes.



The demands electrocemical on the deburring process. The electrolyte solution transfers charge in the gap between the cathode and workpiece, which causes electron transfer from the workpiece to remove surface material.

The methods used up to now – mechanical or thermal processes, or water jet technology – have not achieved the intended productivity levels, nor the desired reproducibility and cost-effectiveness. Leave a Reply Cancel reply. Workpiece material is removed only at precisely defined locations. Manufacturing high-precision surfaces and deburring in an efficient manner with minimal workpiece finishing time is a primary objective of manufacturing engineers working in fields such as aerospace, transportation and energy.

The cathode is designed to maintain a gap between itself and the workpiece surface.

However, this changes drastically when it comes deburrlng the necessary deburring, as the burrs on sections that are difficult to reach must also be removed cleanly and without negative impact on the material. On the contrary, it has up to now been considered a necessary evil.

The dressing of the grinding wheel is required much less frequently.
