What are the design features of turned parts?

1. Length to diameter ratio: Parts suitable for hard turning usually have a small length to diameter (L/D) ratio. The L/D ratio of unsupported workpieces does not exceed 4:1, and L/D. Ratio of supported workpieces D. Not more than 8:1.
2.Tool handle and cutting head: The tool handle is usually composed of an outer shank and an inner shank. The outer shank is cylindrical and the inner shank is prismatic or hexagonal. The joint between them is a conical structure to prevent loosening and slipping. The cutting head is usually prismatic or other shape, and the part connected to the tool handle has a stepped structure, so that the cutting head can be firmly inserted into the tool handle and provide stability during rotation.
3. Blade: The blade is the last part that performs the cutting function. It is usually made of carbide material. Its shape and structure also vary according to different processing requirements. Common blade shapes include circles, triangles, squares, etc. Different blade shapes will have different cutting angles and cutting directions to adapt to the needs of the different materials being processed.
4. Other design features: The connection between different parts of the turning tool is tight, stable and reliable, and the installation of the blade is convenient and quick.
The above characteristics enable precise cutting and processing of turning parts in the machining process, improving production efficiency.
