Workpiece material is removed only at precisely defined locations. This is accomplished through mapping of the cathode geometry into the workpiece. The result is a much higher grinding ratio. Related Posts on Manufacturing topic s. The dressing of the grinding wheel is required much less frequently. Don’t fill this field! We’re here for you Do you have questions or need more detailed information regarding this machine?
Ensuring the cathode is made out of electrically conductive materials. Instead of cutting metal using hardened tooling, material is removed more efficiently by an electrochemical process.
Deburring and electro-chemical Deburring Deburring does not count as a core process in machining. Undercuts, pockets or internal, intersecting drill holes do not present that much ddburring a challenge for mechanical machining processes. One example of a demanding deburring task is to deburrring found in the manufacture of pump housings for common-rail systems.
An example is the treatment for gears. The electrode tool is designed better to focus the metal removal action on the electrocheemical.

Electrochemical grinding 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 dburring the below figure 2.
Controlling the gap by designing the appropriate fixtures including cathodes. The demands made on the deburring process. Contactless deburring with ECM – electro-chemical machining. The debutring material flows through the hole to carry away the burr particles.
Dear Sir, We are looking for purchase electrochemical deburing machine, kindly contact us.
Deburring and electro-chemical Deburring
The workpiece material must be corrosion resistant. Because the cathode never comes into contact with the workpiece, the tooling has no process-related wear. In the case of the EMAG Group, machining, automation and deburring are all covered by their firmly established technologies. The process time is fast as compared to conventional methods and multiple parts per cycle can be machined resulting in a lower unit cost of production.
ELECTROCHEMICAL DEBURRING (ECM)
Electrochemical Deburring and Grinding
Less material is removed in the Electrochemical Deburring ECD machining process; cycle times are much shorter. ECM deburring of a pump housing for common-rail systems. When can you say a System is in Thermodynamic Equilibrium?
Workpieces with complex geometries often contain machining sectors that are difficult to get at. Medium size batch and mass production attach great importance to high quality, and internal burrs and ridges can adversely affect the functioning of a component. The cycle time can be increased if it is desired to round the corner in addition to removing the burr.
ECM is a highly productive process. 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.
To prevent this, it is important to define the machining direction right from the start, when choosing the operating process and the process sequence. Ensuring that the design of the cathode fits the workpiece area to be machined using insulation to protect the workpiece from the ECM process in other areas. Creates a defined edge rounding. On the contrary, it has up to now been considered a necessary evil. The electrolyte flowing between the cathode and the workpiece the anode ensures the removal of the material when flushing the gap.
I have read and understand the data protection information for contact by EMAG.
Components that have intricate shapes with very low finishing tolerances are often needed. Again and again this has led to the machining processes being optimally coordinated, whilst the cost-effectiveness of the system as a whole suffered, owing to the fact that deburring was not taken into consideration as being part of the process chain right from the word go.
It is fair to describe the precision deburring or burnishing of metal components using the electro-chemical machining ECM process as economically highly viable. The mechanical machining and deburding of pump housings is currently considered state-of-the-art. Advantages of this process include:.
Only deburrinh will it be possible to remove burrs economically and with precision. ME Mechanical Team https: Providing short circuit detection at the DC source. Applications of ECG includes devurring of cemented carbide tools, grinding of surgical needles, other thin wall tubes, and fragile parts.
Deburring does not count as a core process in machining.
