Embodiment 1

[0050] The present embodiment provides a high surface quality processing method for a small T-shaped part with weak stiffness and easy oxidation, including the following steps:

[0051] Step 1. Preparation of T-shaped parts blanks:

[0052] like Figure 4 As shown in the figure, a cylindrical material of pure aluminum or pure copper is prepared as the blank material for the processing of T-shaped parts, and the blank material is installed on the machine tool for cutting to prepare a blank part; the blank part includes the front end of the T-shaped part to be processed area 7 and The clamping end 9 at the rear end, the connecting part between the to-be-processed area 7 of the T-shaped part and the clamping end 9 is set as a conical transition 8;

[0053] The goal of the blank processing stage is to remove a large amount of material, the material is pure aluminum or pure aluminum (aluminum or copper content > 99.99%), the overall length of the blank material is 21.5 mm, and the...

Description

technical field [0001] The present invention relates to the technical field of mechanical processing, and more particularly to the technical field of a high surface quality processing method for small T-shaped parts with weak stiffness and easy oxidation. Background technique [0002] With the continuous progress of laser-driven inertial confinement fusion (ICF) physical experiments, laser fusion targets are an important material basis in physical experimental research, and the quality of their processing directly affects the accuracy of physical experimental results. Micro-sized T-shaped parts are a kind of key target parts urgently demanded by ICF physics experiments. Inertial confinement nuclear fusion precision physics experiments put forward extremely high demands on the surface quality after processing, and the surface roughness Ra is required to be better than 20 nm. , the surface is nearly free of machining defects, etc. [0003] The structure of micro-sized T-shape...
