And S200, manually grinding according to the target state to obtain a process product. Specifically, the part to be ground is manually ground through a blank pulling machine.
As a specific implementation of this embodiment, if the target state of the part to be polished is a bright state, step S200 includes:
s211, degreasing and cleaning the surface of the part to be ground. Before manual grinding, the surface of the part to be ground is cleaned, and impurities such as greasy dirt, dust and the like on the surface of the part to be ground are removed, so that the influence on the grinding effect is avoided.
S212, polishing the surface of the part to be polished for a first working time by using first sand paper. The step is primary grinding, and coarse parts such as large particles, burrs and the like on the surface of the part to be ground are removed, so that the surface smoothness and smoothness requirements are preliminarily met. During grinding, the grinding direction needs to be consistent so as to avoid scratches; the force is applied uniformly in the grinding process so as to avoid the defects of uneven surface.
Specifically, the mesh number of the first sand paper is 320 meshes, and the first working time is 8-10min.
S213, polishing the surface of the part to be polished for a second working time by using second abrasive paper to obtain a process product, wherein the mesh number of the second abrasive paper is larger than that of the first abrasive paper. This step is fine grinding to achieve a higher finish and smoothness of the surface of the part to be ground. During grinding, the force needs to be controlled so as to avoid damage to the surface of the part caused by excessive grinding.
Specifically, the mesh number of the second sand paper is 600 meshes, and the second working time is 5min.

And S222, polishing the surface of the part to be polished for a third working time by using red scouring pad, and obtaining a process product. The red scouring pad can thoroughly remove dirt, rust spots and oxide skin on the surface of the part to be ground.
Specifically, the third working time is 8-10min.
S300, carrying out electrolytic polishing on the process product subjected to manual grinding to obtain a finished product. Through electrolytic polishing, no chromatic aberration exists between each part after grinding, so that the production stability and the production efficiency are improved, and the requirements of customers on the appearance of products can be better met. And the one-time electrochemical polishing time is short, and a plurality of parts can be polished simultaneously, so that the production efficiency is greatly improved.
Specifically, step S300 includes:
s301, degreasing and cleaning the process product. And cleaning the ground process product, and removing sand grains and impurities generated by grinding so as not to influence the polishing effect.
S302, placing the process product into an electrolytic tank, and setting a first working voltage and a first energizing time.
Specifically, in this embodiment, if the target state of the part to be polished is a bright state, the first working voltage in this step is 8-12V, and the first power-on time is 2-3min. If the target state of the part to be ground is a matte state, the first working voltage in the step is 2-3V, and the first power-on time is 1.5-2.5min.
S303, placing the electrolyzed process product into a cold water tank. To clean the electrolyte on the surface thereof.
S304, taking out the process product in the cold water tank, putting the process product in a hot water tank, and stirring. Specifically, it is also necessary to wipe the process product clean before it is placed in the hot water tank to remove the liquid residue from the cold water tank.
S305, taking out the process product in the hot water tank, and drying to obtain a finished product.
S400, comparing the surface finish of the finished product with the surface finish of the part in the target state, and performing appearance detection.
S500, if the surface finish of the finished product is different from the surface finish of the part in the target state, the finished product is unqualified, and the steps S200-S400 are repeated until the finished product is qualified. The surface is abnormal due to electrolytic polishing, and the electrolytic polishing can be carried out again after the surface of the product is ground again manually, so that the processing steps are unchanged until the qualified product is produced.
And S600, cleaning the surface of the finished product after polishing. After polishing, the surface of the finished product is cleaned in time, and residues generated by polishing are removed so as not to influence the final surface effect.
It is to be understood that the above examples of the present invention are provided for clarity of illustration only and are not limiting of the embodiments of the present invention. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments.
