How to adjust the size of the rolling cutter?

The rolling cutter has different adjustment methods according to different types. The rolling cutter is divided into the following categories according to the area and machine tool used:

1. Tool rotation class:

1.1、Inner hole rolling cutterC

1.2、Cylindrical rolling cutter (sleeve type) (the diameter of the rolling cutter can be adjusted by loosening the adjusting screw and rotating the adjusting body)

1.3、End surface rolling cutter

1.4、 Plane traverse type rolling cutter

1.5、Taper rolling cutter

2. Workpiece rotation class:

2.1、Diamond rolling cutter

2.2、Single wheel rolling cutter

Except that the needle type inner hole rolling cutter and sleeve type outer circle rolling cutter need size adjustment, other rolling cutters do not need special adjustment. Only the pressing amount (interference amount) can be controlled through the machine tool program!

How to adjust the size of needle type inner hole rolling cutter? The adjustment method is as follows:

Step A. Measure the tool diameter with a micrometer

Step B. After pushing the aluminum shell upward, rotate the aluminum shell left and right to skip the diameter of the inner hole rolling cutter, and the scale value of each grid is 0.0025mm. After adjustment, push the aluminum shell downward to reset.

Because the domestic needle type inner hole rolling cutter is generally of even structure, it is convenient to use micrometer for measurement. However, due to the problem of manufacturing tolerance, the diameter dimensions of the two needles on different radial lines are different, so there is another way to adjust the size of the rolling cutter: Reduce the size of the rolling cutter, then put it into the hole to be rolled, and then increase the size according to the method shown in the above figure until the rolling needle supports the inner wall of the hole and the rolling cutter can be rotated manually, then pull out the rolling cutter while rotating, and then increase the size of the rolling cutter and the machining interference (0.03-0.06mm)
