Circular Magnetic Chucks

A magnetic chuck is a catch acclimated to authority plan pieces. It is about acclimated in abode of automated clamps and vises because it saves set up time and provides a able and compatible captivation force. They are bogus in two footprints: ellipsoidal and circular. Annular or rotary chucks are advised to authority a alternating plan piece. Grinding and axis operations are the archetypal applications for annular magnetic chucks. These chucks are primarily acclimated for captivation locations such as rings or discs.

Construction

Circular magnetic chuck are complete with assumption and animate top plates with a concentric ring that gives best attrition to coolant and accurateness in plan section centering. Dowel pins or screws may be amid in the top bowl to bear the top torque acclimated on lathes, grinders and added accouterment with abundant cuts. chuck top plates may be machined for plan with odd configurations. The top bowl is magnetic with anniversary pole alone magnetized by bowl abiding magnets, so electrical controls and blooper rings are not required.

Magnetic Pole Types and Pitch

Circular magnetic chucks can be complete with axle and longitudinal pole types. In axle pole types, the poles run beyond the chuck from ancillary to side. The pole agreement varies from chuck to chuck and determines how abundant of the workpiece can be magnetized. In longitudinal pole type, the poles run the breadth of the chuck. For attenuate plan pieces attenuated pole angle is best while a added pole angle is bigger for thicker parts.

Types of magnetic Circuits

Since these annular chucks are alternating if in operation, abiding magnetic or electro-permanent magnetic circuits are universally activated because they crave no electrical ability if in operation, no electrical controls or blooper rings to alteration D.C. ability from the ascendancy to the magnets.

Permanent magnetic chucks use activating bowl magnets to accomplish a magnetic captivation force. The magnetic force is actuated with a automated lever. The batten aligns the magnetic packs to absolute the magnetic force from the top bowl through the plan section and assuredly to the basal plate, commutual the magnetic circuit. If the batten is reversed, the magnetic armament are independent aural the chuck and abroad from the plan piece, which allows the section to be released.

Electro-permanent magnetic chucks (commonly alleged electroperms) are complete with a braid anguish about abiding magnetic actual anchored in the chuck plate. They use a chuck ambassador to administer a DC voltage to the coils to allegation the magnetic material. This takes about 1 additional and deeply binds the plan section to the chuck. Electroperms will abide magnetic even if ability is removed, which gives them a fail-safe feature.
