In industry sectors such as aerospace, automotive, energy, and medical, precision finishing of machined parts is critical to the refinement of end product performance levels. Deburring does not count as a core process in machining. 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 electgochemical deburring process to suit the desired output rate.

Trust our experts to manage these key process considerations: The electrolyte flowing between the cathode and the workpiece the anode ensures the removal of the ellectrochemical when flushing the gap. The shape of the cathode determines the final shape of the workpiece or the impression imaging placed upon the workpiece.

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.

Instead of cutting metal using hardened tooling, material is removed more efficiently by an electrochemical process. The demands made on the deburring process. Contactless deburring with ECM – electro-chemical machining.

Electrochemical deburring

Advantages of this process include:. The ECM process is a revolutionary way to manufacture high precision components.

The 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. This is accomplished through mapping of the cathode geometry into the workpiece. ECM is an ideal deburring process for electrochemicak where burrs are difficult to reach or machine using conventional methods, and it eliminates the challenge of secondary burr formation.

Ensuring the cathode is made out of electrically conductive materials. We’re here for you Do you have questions or need more detailed information regarding this machine?

However, this changes drastically 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 the material. The electrolyte solution transfers charge elrctrochemical the gap between the cathode and workpiece, which causes electron transfer from the workpiece to remove surface material.

One example of a demanding deburring task is to be found in the manufacture of pump housings for common-rail systems. Abrasives materials used in ECG include aluminum oxide and diamond. Components that have intricate shapes with very low finishing tolerances are often needed.

To prevent this, it is important to define the machining direction right from the start, when choosing the operating process and the process sequence. Eletrochemical speed of material removal is dictated by the DC current applied. Removes burrs at bore exits and at intersecting holes in a workpiece caused by conventional drilling.

An example is the treatment for gears. However, a precondition is that the whole process is mastered.

ECM is a highly productive process. 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.

The mechanical machining and deburring of pump housings is currently considered state-of-the-art. With regard to the deburring process this is electrocheimcal great importance, as the relatively small problem of a burr can very quickly escalate to a crisis.

On the contrary, it has up to now been considered a necessary evil. Controlling the gap by designing the appropriate fixtures including cathodes.

Workpiece material is removed only at precisely defined locations. The dressing of the grinding wheel is required much less frequently.

ELECTROCHEMICAL DEBURRING (ECM)

The separation distance between the cathode and the workpiece is key to electfochemical the material removal process. Creates defined surface structuring to optimize the tribology at the component surface — retaining oil at a bearing surface. I have read and understand the data protection information for contact by EMAG. 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.

The workpiece material must be corrosion resistant. When can you say a Deburrong is in Thermodynamic Equilibrium? There are no mechanical loads or thermal loads on the workpiece.
