Dividing heads are indispensable tools for machinists and engineers who require precise angled cuts or rotations. They work alongside milling machines or similar tools to divide workpieces equally or rotate them to specific angles. The key components of dividing heads are a spindle and a worm gear. The spindle can be rotated to any angle which is mounted on a swiveling base. The worm gear meshes with a worm wheel attached to the spindle. Turning the worm gear rotates the spindle, achieving the desired division or rotation of the workpiece. To use a dividing head, the workpiece is mounted on the spindle and secured. The operator sets the worm gear to the desired ratio, determining the spindle's rotations per turn of the worm gear. As the worm gear is turned, the spindle rotates, accomplishing the desired angle division or rotation. Dividing heads are versatile and reliable, providing accurate results, which is why they are a valuable addition to any workshop. They are also used in manufacturing some exterior car panels.
