Geometric Model of NC Machine tool for Spiral Bevel Gear

According to the spiral bevel gear CNC machine tool of Gleason Company, the geometric model of the CNC machine tool is established, and the machine mechanism is shown in the figure.

The machine tool has the advantages of simple mechanism, good rigidity and strong versatility, and can process two kinds of tooth systems. The head part of the machine tool adopts two sets of horizontal and vertical guides, so that the spindle box can move in a plane perpendicular to the axis of the spindle.

The machine tool worktable is provided with a set of guide rails parallel to the axis of the spindle, the axis of the workpiece fixture is arranged horizontally, and the fixture seat can be rotated around the axis in the vertical direction.
