Periodic magnetic finishing machine

Abstract

The present invention is related to finishing mechanical, electronic, and jewelry workpieces. The system comprises a container -including an abrasive medium-, a control unit, a measurement unit, and a display. Adjusting the rotational and vibration motion is conducted using magnetic coils and eccentric weights in the control unit. Moreover, the control system can tune the container's tilt angle. The magnetic coils enclose the container producing a magnetic field, thereby pulling the abrasive particles against the target surfaces. The container is held by two motors located at its top and bottom, which provide the rotational movement of the container around its axis. Besides, the rotary motors that hold the container are bound by the structure related to the vibration motors, which are paid by the vibration motors of the container assembly and the materials inside it due to the resulting vibration. Finally, these motors are placed on the device's frame with the help of a vibration damping system (springs), which allows the device to be adjusted at different tilt angles and create a rocking motion with the help of an angular movement mechanism. The printing circuit companies, ornamental jewelry companies, and factories producing mechanical parts are potential customers of this equipment that can use this machine for surface finishing aiming to increase the surface smoothness on a micro scale for a large number of parts.
