Title:
MAGNETIC CHUCK
Document Type and Number:
WIPO Patent Application WO/2019/225957
Kind Code:
A1
Abstract:
TThe present invention relates to a magnetic chuck for supporting a workpiece to be milled, ground, or the like to be immovable and, more specifically, to a magnetic chuck, which can variously change the positioning of the workpiece according to a table structure, a machining form, a machining method, and the like, and has a simplified structure, thereby enabling reduced manufacturing processes and costs, the magnetic chuck comprising: a magnetizable core; a conductive coil wound around the circumference of the magnetizable core; a first conductor coupled to one end of the magnetizable core; a second conductor coupled to the other end of the magnetizable core so as to face the first conductor in parallel; and an insulator for blocking a magnetic path by encompassing the magnetizable core and the conductive coil between the first conductor and the second conductor, wherein, when the first conductor and the second conductor are stood upright on the table, an air gap is formed such that either one end of the first conductor or one end of the second conductor does not come into contact with a table in order to block the magnetic path.
