Long, magnet coil is not just applied to.Therefore set forth herein electromagnet is replaced with permanent magnet, the long appearance of magnet coil processing is overcome
Easy heating problem.It is with strong applicability, and device is small, it is lightweight, it is not necessary to electric supply installation.But magnetic grinding is hard crisp in processing
Material, for example ceramic material, processing efficiency is low.Therefore, if during magnetic grinding, introducing vibration, it will further
Improve grinding effect, improve processing efficiency.And vibrating can keep abrasive particle well interior in the intervals of business, promote abrasive particle
It is mobile and from sharp, and the cutter trade produced in process of lapping can be eliminated, improve surface quality.Because vibration can make
Abrasive particle produces dither to workpiece surface, reduces workpiece surface residual stress, produces compression, improves workpiece antifatigue strong
Degree, lifts its service life.
During ultrasonic wave added magnetic grinding, the amplitude very little that transducer is produced, it is impossible to the need for meeting grinding.Cause
This, can be amplified by using ultrasonic transformer to amplitude, so as to meet processing needs.Ultrasonic transformer amplification amplitude principle is basis
Ultrasonic wave law of conservation of energy in ultrasonic transformer transmittance process, because ultrasonic transformer large end face is connected with transducer, small end is ined succession work
Have head, and by the energy constant of luffing rod end surface unit area, therefore output end amplitude becomes big, disclosure satisfy that wanting for processing
Ask.
