How to use:



The

die is used to tap the external thread. Before tapping, the cutter with

the diameter of the bar should be selected to cut the lubricating oil.

The diameter of the bar is very important. It can not be larger than the

nominal diameter of the required thread. It should be smaller than the

nominal diameter of about 0.050.15. The diameter is too large, which is

easy to cause cutting difficulties and damage the die. The diameter is

slightly smaller, which is conducive to tapping the thread, and maintain

enough thread height. Install the end face of the die with the cutting

cone upward into the cutter The positioning groove shall be aligned with

the fastening screw in the middle of the winch, and the screw shall be

clamped into the plate groove and tightened. The end of the bar stock

shall have a 1'45 ° chamfer, but the chamfer shall not be too large, and

the excessive chamfer is not easy to cut in. When tapping the thread,

the cutting cone of the die shall face the bar stock and try to keep the

two coaxial.

The

die rotates the cutting screw clockwise and reverses every 1 / 4-1 / 2

turn, so as to clean the chips from the outside of the plum blossom

hole, and continue to operate until the required thread length is

reached. When tapping the thread, appropriate lubricating oil shall be

added, and the lubricating oil shall be added to the die cut
