Rotating center Morse taper 4 (MT MTA MTB MK) movable

A rotating turning center is used for fixing workpieces with rotating bodies on the tailstock of a metalworking machine.

The design of this type of equipment allows processing at high speeds with minimal runout.

Rotating centers can be used on lathes and grinding machines with manual, semi-automatic and numerical control.

Basic rules for operating rotating centers necessary for precision machining of parts:

When choosing the accuracy class of the equipment, it is necessary to leave a margin to cover runout errors due to other reasons - wear of bearings, low rigidity, etc. Correct installation of the part plays an important role. The axis of the cone must coincide with the axis of rotation of the workpiece with high accuracy. To check the accuracy of the installation, you can place a white sheet of paper under the rotating center and evaluate the alignment. More precise control is carried out using indicators. If there is runout, the cone is ground in place and checked against a template. Processing is carried out with a power tool located in the tool holder. The beating of the rotating centers leads to the beating of the resulting part relative to the axis. When installing this part on another machine that has a different runout, a deviation from alignment may occur. To eliminate deviations, processing is carried out using a fixed center.
