EDM Magnetic Chucks Enhance Productivity Through Palletization

https://www.youtube.com/watch?v=Pf_WNxsAfK8

As with most magnetic work holders, EDM chucks provide uniform, full magnetic holding coverage over the entire surface in the work piece. CNC programming is simplified since setup, changeover and destroy rates are drastically reduced.

The EDM process is popular by moldmakers, but can be utilized to manufacture prototypes, aspects of complex shapes, difficult materials with close tolerances, or low quantity production parts within the aerospace, automobile and electronics industries. Traditionally, EDM work pieces were clamped and strapped onto plates. This caused more setup time, an inability to set multiple work pieces for a passing fancy plate, an inability to automate and caused more advanced CNC programs. EDM magnetic chucks remove the unproductive unwanted effects of mechanical clamping. techno

Introduction to EDM Magnetic Chucks

EDM magnetic chucks are constructed of encapsulated ceramic or Neodymium (rare earth) permanent magnets and is controlled mechanically or electronically depending on the application. They possess a low magnetic height to lower secondary erosion. A superb magnetic pole distribution provides a uniform magnetic holding force that allows for sparking parts better the chuck surface to get rid of interference through the magnetic field from distorting the EDM process. Additionally, the fine pole design won't hinder flushing. As with every magnetic work holders, EDM chucks provide uniform, full magnetic holding coverage through the entire area with the work piece. CNC programming is simplified since setup, changeover and destroy rates are drastically reduced.

Magnetic Control

EDM magnetic chucks can be controlled manually having a lever that turns the magnetic force off or on. No electrical energy is necessary, giving it portability and an intrinsic failsafe feature. They can also be controlled electronically, that gives the chuck a flexible holding force, by 50 % ways: electro-permanent and electromagnetic control.

Electromagnetic chucks are made from electrical coils wound around a steel core embedded in the chuck. To energize the electromagnetic field, a chuck controller is employed to generate a variable DC voltage in the chuck's coils. The chuck's poles are magnetic as long as voltage is used. The operator can adjust the controller's DC voltage to vary the strength of the magnetic field, which, consequently, provides variable holding force.

Electro-permanent magnetic chucks (commonly called electroperms) really are a hybrid in the permanent and electromagnetic chuck types. They're constructed with a coil wound around magnet material embedded in the chuck plate. Whenever a DC voltage is used, the magnetic materials are charged, which takes about 1 second, and supports the workpiece despite power is slowly removed. They've got variable holding power capability much like electromagnetic chucks. Power is essential is de-energize the magnetic field. This offers them both a failsafe edge on electromagnetic chucks and eliminates the accidental relieve work piece.

The power Automation

EDM magnetic chucks will be more flexible and taking machining multiple parts with one setup or several elements of varying dimensions. Conventional chucking will need a lot more setup time and energy to prepare for the EDM process. An additional advantage of magnetic workholding is palletization. Within a setup, EDM pallets could be moved from a 5-axis machine, to the EDM, drilling operation, or some other machine that is certainly build for pallets.
