Features of Thread Rolling Machine Steel Stainless Steel
It is suitable for radial and axial processing of various threads below 36. It can be used as bolts or threaded rods (threads). It is equipped with time control, high efficiency, reasonable structure, and easy operation.
Wear & Refurbishment of Thread Rolling Machine Steel Stainless Steel
The rolling wheels must be adjusted synchronously, that is, to
adjust the coincidence of the indentations of the L and R wheels on
the surface of the workpiece. If the synchronous adjustment is
inaccurate, the workpiece will have chaotic teeth, chips, and
out-of-tolerance conditions. The center height of the workpiece is
consistent with the center height of the rolling wheel (allowing a
lower 0.01-0.08mm). The commonly used adjustment methods are:
After the rolling wheel is worn out, the teeth can be ground off to
reduce the number of teeth, and the parameters can be calculated
again according to the above process, and the teeth can be re-cut
to produce a refurbished rolling wheel, which can be refurbished
multiple times within the allowable range of the center distance of
the machine tool.

Common problems and solutions of thread rolling machine
1. The order of changing the inner gasket of the thread rolling
wheel: clockwise: thick, medium, and thin, and outer gasket, thin
and medium;
2. Fine-tune the size: After loosening the six inner angle screws
(or three outer hexagonal screws) behind the rolling wheel head,
use an adjustable wrench to fine-tune the size;
3. The length of wire adjustment: adjust the stopper distance on
the double-stroke switch;
4. Adjust the length of the leather: adjust and install the square
seat on the retracting shaft;
5. Car anti-wire
(1) The gaskets in the thread rolling wheel are installed in
reverse order
(2) Push button switch up
(3) Turn on the machine and peel the skin counterclockwise, press
the button switch on the back button to roll the thread clockwise,
and then return the thread counterclockwise
