He has made significant contributions to the field of manufacturing technology, particularly in the development of automatic chamfering machines. With a total of 3 patents to his name, Yoshikawa's innovations have enhanced the efficiency and precision of machining processes.

Latest Patents

One of Yoshikawa's latest patents is an automatic chamfering machine designed for ceramic honeycomb structural bodies and similar workpieces. This machine features a clamping device that securely holds the workpiece while allowing it to rotate in one direction. The grinder wheel's movement is controlled by a tracer element that maintains contact with the workpiece's peripheral surface, enabling an autoprofiling chamfering operation. This design ensures that a consistent amount of material is removed, even when the workpiece has an irregular outer contour or is clamped inaccurately.

Another significant patent is a clamp device specifically designed for clamping workpieces with surface curvature, such as ceramic shaped bodies. This device includes support members mounted on a base frame, which can swing about predetermined rotational axes. The first clamp members are also mounted on the base frame, while the second clamp members are on a sub-frame that moves relative to the base frame. This innovative design allows the second clamp members to move toward the first clamp members, effectively clamping the workpiece securely.
