Techniques for Precision Parts Processing

(4) The accuracy of sawing dimensions is not high

When sawing Precision Parts, factors such as uneven coordination between the left and right hands, weak sense of responsibility for size control, and weak measurement technology and grasping ability often result in inaccurate sawing dimensions (with a maximum difference of more than 3-4mm) and rough surfaces, which do not meet the precision requirements of instruments and equipment. According to the relevant data of sawing skills training, about 56% of sawing dimensions have upper deviations, about 23% have lower deviations, and overall, over 21% do not meet the standards for precision parts.

(5) The problem of saw blade breakage or saw seam deviation

When processing precision parts, factors such as incorrect installation position, improper installation of saw blades, unsuitable clamping force, mismatch between processing control force and pressure, distortion of saw bow plane, inconsistency between plumb line and processing interface, etc. have led to frequent occurrences of saw seam deviation, uneven saw blade, and saw blade breakage during part processing. This greatly affects the manufacturing efficiency and efficiency of precision parts, increases their manufacturing and maintenance costs, and is not conducive to the development of precision instruments or equipment that require precision parts.

2. Precision Parts Processing Skills of Fitters
(1) Processing Techniques for Welding Strip

As a precision component of the equipment, the required material specifications for welding strips are generally 0.2mm thick, 25mm ± 0.05mm wide, and 1300mm ± 0.5mm long hot copper T2Y. Gantry planing machines and rolling belt cutters are often used as processing tools. In addition to making two compression plates with similar flatness and high flatness in advance, the upper and lower rolling belt cutters also need to be installed on the two main shafts of the rolling belt machine, At the same time, it is necessary to adjust the horizontal and vertical positions between the two to ensure that the fit gap is within the range of 0.005mm-0.01mm. Using such processing techniques can not only fully meet the requirements of design drawings, but also improve the production efficiency and quality of components, reduce material loss, and save production costs.

(2) Processing Techniques for Balancing Screws
In the processing of a wide variety of precision parts, balance screws are difficult to process due to requirements such as deep opening grooves, small width, and small dimensional tolerances, which can lead to scratches and out of tolerance in overall dimensions. The technological breakthrough process is slow. From the perspective of traditional processing technology, combined with existing measuring tools, it is possible to polish the mold and lubricate the opening groove before processing. At the same time, a clamping fixture can be designed to allow the workpiece and the fixture to be processed simultaneously during processing (with a small gap between the fixture and the workpiece). This not only improves the rigidity of the opening groove, reduces the probability of deformation, but also meets the accuracy requirements of the required components.
