The unique universal structure design endows the spindle with the ability to rotate freely 360° and adjust at multiple angles of inclination. It can easily handle tapping tasks at complex spatial positions such as curved surfaces, inclined holes, and cross - holes. There is no need to customize additional tooling fixtures. Through simple parameter settings and angle adjustments, precise tapping can be completed on the surface of irregular workpieces, greatly expanding the equipment's processing range and application scenarios. It is especially suitable for industries such as mold manufacturing and medical device manufacturing, which have strict requirements for the structural accuracy of workpieces.
