Rectangular square pole electric permanent magnet chuck

Product Introduction

The permanent magnet device, which adopts the principle of bipolar magnetic difference and is controlled by a brief pulse current, has a huge magnetic force and long-term stability due to the use of rare earth permanent magnet materials as the main magnetic pole. Electric permanent magnet suction cups do not require electrical energy during operation, and only rely on permanent magnet suction to hold workpieces, avoiding the danger of workpiece detachment caused by the loss of magnetic force of electromagnetic suction cups in the event of sudden power failure or wire damage. The use of electric permanent magnet suction cups is very simple and fast, with no moving parts inside the fixture system, reliable and durable, and strong practicality. The conversion process between magnetization and demagnetization only takes 1-2 seconds, and the efficiency of clamping and releasing the workpiece is very high. Strong suction and low residual magnetism. Power off without demagnetization, safe to use. Small thermal deformation, no moving parts, long service life, and reliable operation. Easy card installation and time-saving. Five sided processing, no blocking phenomenon, and can also be chamfered on the bottom surface when combined with magnetic conductors. The suction cup adopts an integral structure with high rigidity and stability. The large capacity suction cup adopts a dual element control circuit and phase balance, so the high-order harmonics are extremely small and do not interfere with other devices. The suction force after excitation of the suction surface shall not be less than 28 kilograms per square centimeter.

Specification and model

Residual magnetism: ≤ 5% of the suction force at that point. Suction force: ≥ 280N/cm2

Application

Widely used in high-precision grinding, cutting and other precision machining of various machine tools such as surface grinders, CNC milling machines, machining centers, etc.
