U-axis processing

What is U-axis processing?

  1. U-axis processing is a processing method that enables the process which could be handled only with a lathe to be completed with a machining center.
  2. Due to the NC control of in the direction of diameter, accurate processing of curved surface, sphere and taper are possible.
  3. Processes can be consolidated since a machining centre can undertake lathe processing.
  4. With NC controlled honing tool in the direction of diameter with U-axis function, it realizes accurate honing processing.

With U-axis, the processing that can be done only with the lathe is now undertaken by a machining centre.

Various processing with a machining center

A machining center can handle various processes: step processing, arc processing, taper rolling, curved surface processing, grinding finishing processing, leakage prevention, grooving, inside and external runout process, large diameter screw processing, and rolling. In addition, a variety of special processing can be handled such as honing processing depending on ideas.

One tool is enough to handle step process, arc process and taper rolling.

U-axis

Honing tool can handle high precision honing processing.

Features of U-axis processing

1.Much less number of boring tools is needed.

・One U-axis tool are capable of doing jobs for several boring tools.

U-axis

2.Easy preparation. Cutting process of deformed work

・Lathe process generally has to take balance of work. With U-axis processing, work can be fixed at M/C.
