With regard to the deburring process this is of great importance, as the relatively small problem of a burr can very quickly escalate to a crisis. The electrolyte flowing between the cathode and the workpiece the anode ensures the removal of the material when flushing the gap.
Trust our experts to manage these key process considerations: The demands made on the deburring process. It is fair to describe the precision deburring or burnishing of metal components using the electro-chemical machining ECM process as economically highly viable. Undercuts, pockets or internal, intersecting drill holes do not present that much of a challenge for mechanical machining processes.
Providing short circuit detection at the DC source. Using the electro-chemical deburring process instead of conventional deburring methods mechanical or water jet deburring has elechrochemical costs quite significantly and made ddeburring possible to match the cycle time to electrkchemical start-up and production phase by scaling the electro-chemical deburring process to suit the desired output rate.
The ECM process is highly stable with very good process control which ensures accuracy, quality, consistency and the highest repeatability.
The abrasive grits protruding from the grinding wheel at the contact with the workpart establish the gap distance. The separation distance between the cathode and the workpiece is key to regulating the material removal process.
Electrochemical Deburring and Grinding
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. Optimizes the surface characteristics of the workpiece. Removes burrs at bore exits and at intersecting holes in a workpiece caused by conventional drilling. Deburring and electro-chemical Deburring Deburring does not count as a core process in machining.
The electrode tool is designed better to focus the metal removal action on the burr. The effects of component stress as a result of the manufacturing process are also a concern for components that will be functioning under extreme operating conditions.
The mechanical machining and deburring of pump housings is currently considered state-of-the-art. Only then will it be possible to remove burrs economically and with precision.
The cycle time can be increased if it is desired to round the corner in addition to removing the burr. Related Posts on tag s.

ELECTROCHEMICAL DEBURRING (ECM)
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 electrochemidal material. An example is the treatment for gears.
ECM is an ideal deburring process for parts where burrs are difficult to reach or machine using conventional methods, and it eliminates the challenge of secondary burr formation. Request offer You have questions or need detailed information?
Deburring and electro-chemical Deburring
Creates defined surface structuring to optimize the tribology at the debureing surface — retaining oil at a bearing surface. This makes ECM ideal for the following surface machining applications: Controlling the gap by designing the appropriate fixtures including cathodes. The electrolyte solution transfers charge devurring the gap between the cathode and workpiece, which causes electron transfer from the workpiece to remove surface material.
Deburrng fill this field! Medium size batch and mass production attach great importance to high quality, and internal burrs and ridges can adversely affect the electrochemica of a component. In the case of the EMAG Group, machining, automation and deburring are all covered by their firmly established technologies.

Workpieces with complex geometries often contain machining sectors that are difficult to get at. On the contrary, it has up to now been considered a necessary evil. The ECM process is a revolutionary way to manufacture high precision components. However, a precondition is that the whole process is mastered. A typical cycle time in ECD is less than a minute.
In industry sectors such as aerospace, automotive, energy, and medical, precision finishing of machined parts is critical to the refinement of end xeburring performance levels. Abrasives materials used in ECG include aluminum oxide and diamond. When can you say a System is in Thermodynamic Equilibrium? Workpiece material is removed only at precisely defined locations.
