How to remove the half tooth of thread on CNC lathe?

Generally, when machining screws on a lathe, the workpiece is rotating and the mold is static. However, for the screw shown in the circle, the diameter is small and it is not easy to clamp, so it is better to remove the half tooth. The operation steps are as follows:

1. Clamp the die on the three claws and prepare for oil tapping. Diesel oil is used here. Because of its good wettability, it is used as lubricating fluid.

2. Fix the stationary workpiece with wire cutters. In order to prevent the screw from being clamped, a layer of aluminum skin or copper skin can be wrapped around the screw;

3, then screw the thread into the mold, and then start the lathe, and the half tooth can be removed at a slow speed of more than 20 revolutions;

Extended data:

The programming methods of half tooth removal of CNC machine tools can be divided into manual programming and automatic programming.

1, manual programming, all the contents of the program are written by hand according to the instruction format specified by the numerical control system.

2. Automatic programming is computer programming, which is divided into automatic programming method based on language and automatic programming method based on painting. However, no matter what automatic programming method is adopted, corresponding hardware and software are needed.

The controlled actions of automatic programming generally include the start and stop of machine tools; Start and stop of spindle, change of rotation direction and speed; Direction, speed and mode of feed movement; Tool selection, length and radius compensation; Tool replacement, startup and shutdown of coolant, etc.
