摘要： A mold machining method using an endmill, the contour of a cross section of the mold being concave and continuous in an area, a ratio of the maximum to the minimum of radius of curvature of the contour of a portion of the area (a first area) being 2 or greater, and a blade of the endmill having a second area where the contour of a cross section is similar to the contour of the first area, the method comprising the steps of determining a spiral path of the endmill such that each point of the first area is machined by a portion of the second area, corresponding to said each point in the similarity, and a radial interval between the spiral tool path is maximized while keeping surface roughness of the machined mold at or below a predetermined value; and machining the mold along the path.

摘要： A device for removing flashes of a wheel blank includes two layers of turnover mechanisms, wherein the lower-layer turnover mechanism realizes the initial positioning of a wheel and has the function of removing the flashes at both the inner side and the outer side of an inner rim of the wheel, and the upper-layer turnover mechanism realizes the secondary positioning of the wheel and has the function of removing the flashes on the outer rim side. By means of the two layers of turnover mechanisms, the flashes on the front face and end face of a wheel blank outer rim wheel lip, and the inner side and outer side of the inner rim are removed, and coaxial processing conversion and orderly takt connection are ensured. The disclosure also provides a method for removing flashes of a wheel blank.

摘要： An orbital drill bushing adapter for use with a drill unit. In one embodiment, the orbital drill bushing adapter comprises a main body and locking arms. The main body includes a base member having an upper surface, a lower surface, and an external side wall that extends between the upper surface and the lower surface. The main body further includes a cylindrical spacer that projects from the lower surface of the base member, and is configured to fit in a drill hole of an orbital drill bushing. The main body includes a cylindrical hole that passes through the base member and the cylindrical spacer. The locking arms are pivotally coupled to the base member, and are configured to clamp the main body onto the orbital drill bushing.
