Embodiment Construction

[0025] Below by embodiment the content of the present invention is specified:

[0026] According to the surface ultrasonic processing method of the present invention, the process step of carrying out surface processing to molybdenum rod is as follows:

[0027] (1) Install the molybdenum rod on the lathe, so that the workpiece is in the center of the lathe, and the runout is ≤0.05mm;

[0028] (2) Adopt suitable tool to produce molybdenum rods with basic dimensions and geometric tolerances and surface roughness up to 3.0-5.0 μm that meet the requirements of the drawings; in this embodiment, it is φ240mm molybdenum rods after turning, with a purity > 99%, the surface roughness is 3.12μm;

[0029] (3) Connect the cable between the ultrasonic cutter and the external ultrasonic generator;

[0030] (4) Adjust cutting parameters: the linear speed of ultrasonic tool processing is adjusted to 71m / min, and the cutting speed (ie feed per revolution) is adjusted to 0.15mm / r;

[0031] (5...

Description

technical field [0001] The invention relates to a metal surface processing technology, in particular to an ultrasonic processing method for the surface of a tungsten / molybdenum product. Background technique [0002] The surface roughness requirements of parts in mechanical manufacturing are always an important issue for engineers and technicians to consider when making processing plans and using equipment. Surface roughness is one of the important indicators to measure the quality of the processed surface, and it has a great influence on the wear resistance, corrosion resistance, fatigue strength and matching properties of parts. When the surface roughness value of the machined parts is low, the commonly used method in engineering technology is to use grinding processing. For example, when the workpiece size is large, the structure is special or the conditions for grinding processing are not available, grinding processing is often used to achieve the roughness value. lower ...
