Latest Patents

One of Yoshioka's latest patents is a rotary table unit. This invention features a stationary base element and a table element that is rotatably mounted on the base. The design incorporates hydrostatic and hydrodynamic bearing guides, creating a composite bearing guide mechanism. This mechanism allows for smooth and stable rotation of the table element, even under local loads. Additionally, the rotary table unit is equipped with a main drive motor and an auxiliary drive motor, which work together to adjust the drive force in response to changes in load.

Another significant patent is a method for producing a grinding wheel by electroplating. This method involves immersing part of the outer peripheral portion of a grinding wheel body in a plating solution. While the grinding wheel body rotates at a low speed, electric current is supplied to create a pre-plating layer of uniform thickness. The process continues with the adherence of abrasive grains to the pre-plating layer, followed by pressing the grains into the layer to achieve a uniform projection height. Finally, a final plating is conducted to secure the abrasive grains.
