Analysis of common thread size:
CNC lathes need a series of sizes for the processing of ordinary threads. The calculation and analysis of the size required for the processing of ordinary threads mainly include the following two aspects:
1. Workpiece diameter before thread processing:
Considering the expansion of the thread shape, the diameter of the workpiece before the thread processing is D/D-0.1p, that is, the thread diameter is reduced by 0.1 pitch, which is generally 0.1 to 0.5 smaller than the thread diameter according to the material deformation ability.
2, thread processing feed:
The amount of thread feed can refer to the bottom diameter of the thread, that is, the final feed position of the thread cutter.
Thread path: large diameter -2 times the tooth height; Tooth height = 0.54P (P is pitch).
The feed amount of thread processing should be continuously reduced, the specific feed amount is selected according to the tool and the working material.
