Contactless deburring with ECM – electro-chemical machining: It is fair to describe the precision deburring or burnishing of metal components using the. Although deburring technology is used in precision manufacturing and high- quality machining, deburring is still considered a difficult problem. Deburring and edge finishing technology as the final process of machining operation is required for manufacturing of advanced precise components. Fitting a.

Wear-resistant, precise, contactless and economical are all predicates that apply to the ECM deburring process.
The ECM process is highly stable with very good process control which ensures accuracy, quality, consistency and the highest repeatability. 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.
Published hundreds of articles on various engineering topics. Because the cathode never comes into contact with the workpiece, the tooling has no process-related wear. The material removed during the deburring process must be filtered out of the electrolyte stream in order to maintain constant electrolyte quality in the gap between the cathode and the workpiece.
Creates defined surface structuring to optimize the tribology at the component surface — retaining oil at a bearing surface. The result is a much higher grinding ratio. Deburring and electro-chemical Deburring Deburring does not count as a core process in machining.
The speed of material removal is dictated by the DC current applied. Workpiece material is removed only at precisely defined locations. Elrctrochemical fixture including the tool cathode is a critical element of the ECM process because its properties and shape determine where and how much material is removed from the workpiece.
Our machines improve the precision of finished product profiles with complete processing in a fraction of the time required by other methods. The electrode tool is designed better to focus the metal removal action on the burr.
An example is the treatment for gears.
The cycle time can be increased if it is desired to round the corner in addition to removing the burr. The electrolyte solution transfers charge in the gap between the cathode and workpiece, which causes electron transfer from the workpiece to remove surface material.
Request offer You have questions or need detailed information? A typical cycle time in ECD is less than a minute. Workpieces with complex geometries often contain machining sectors that are difficult to get at. Leave a Reply Cancel reply.
This makes ECM ideal for the following surface machining applications: This is accomplished through mapping of the cathode geometry into the workpiece.
However, this changes electrochwmical when it comes to the necessary deburring, as the burrs on sections that are difficult to reach must also be removed cleanly and without negative impact on elecgrochemical material.

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.
ELECTROCHEMICAL DEBURRING (ECM)
The demands made on the deburring process. Components that have intricate shapes with very low finishing tolerances are often needed. 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 in the below figure 2.
Another difficulty in practical applications is the so called “”secondary burr””, i. electroochemical
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. Visit our about section to know more. ECM is a highly productive process. Electrochemicl the cathode is made out of electrically conductive materials.
Controlling the gap by designing the appropriate fixtures including cathodes.
