What are electromagnetic chucks used for?

Processing various ferromagnetic materials on metalworking machines would be difficult without the use of special magnetic or electromagnetic holders (chucks), also called electromagnetic tables. These are elements whose task is to immobilize and hold metal details during their processing. They are used e.g. in grinders, milling machines or lathes.

What are the biggest advantages of using electromagnetic chucks?

The greatest benefits of using electromagnetic chucks during machining include:

• Shortening the time of preparing the workpiece for processing (up to ten times);
• The possibility of convenient processing of both the front and side surfaces of the detail, and no risk of deformation of the workpiece.
• The possibility of convenient processing of both the front and side surfaces of the detail, and no risk of deformation of the workpiece.

The electromagnetic chucks characterize: resistance to cooling liquids, possibility of use during automated production; waterproof construction; easy installation, and constant clamping force. The workpiece is fixed to the machine tool with only one plane, thanks to which tools can easily reach its other surfaces.

What are Electromagnetic chucks made of?

Electromagnetic machining chucks are designed to hold workpieces made of ferromagnetic materials during machining. They are equipped with a non-magnetic gripping plate, a power cord, two limiting strips and poles with windings. Unlike magnetic chucks, electromagnetic chucks use electromagnets instead of permanent magnets. Therefore, when for some reason the power is turned off, they will stop working and the workpiece will not be properly held. Therefore, when installing them, it is necessary to introduce changes in the machine control, which in the event of a power failure and the release of the electromagnet will stop the machine immediately.

Electromagnetic chucks are used in many metalworking machines used in various industries. These include: grinders, milling machines and lathes. Thanks to them, it is possible to process details in one clamping.

In order to facilitate the removal of details mounted on the electromagnetic table (chuck), a demagnetizer is connected to the table’s power supply system, which demagnetizes the detail and facilitates its removal.
