Problems solved by technology

[0003] The traditional air spindle surface treatment method is to add cleaning fluid to the pool and use ultrasonic vibration to clean it. This method greatly improves the cleanliness of its air spindle, but there are residues on its surface anyway, such as cutting fluid, oil stains, and Surface scratches caused by careless replacement or insufficient compressed air
For CNC equipment, these residues will greatly reduce its precision
And the general polishing process also stays in the method of manual sanding, it is difficult to restore the smooth surface, and the production efficiency is very low

Embodiment Construction

[0020] The polishing treatment method of the air spindle of the present invention will be further described in conjunction with the examples below, but the present invention is not limited thereby.

[0021] The polishing treatment method of the air spindle of the present invention comprises the following steps:

[0022] Place the air spindle cleaned by ultrasonic vibration in the plasma reaction chamber;

[0023] adjusting the degree of vacuum in the plasma reaction chamber to a first value;

[0024] Introduce oxygen and argon into the plasma reaction chamber and maintain the vacuum;

[0025] The cathode radio frequency frequency of the plasma reaction chamber is controlled to be 80-100 KHz, and the anode radio frequency frequency is controlled to be 30-35 MHz, so as to realize the first glow discharge.

[0026] Specifically, before the etching gas is introduced, the vacuum degree of the plasma reaction chamber is 550-600 Pa, for example, oxygen gas and argon gas are introdu...

Abstract

The polishing treatment method of the air spindle of the present invention includes: placing the air spindle cleaned by ultrasonic vibration into the plasma reaction chamber; adjusting the vacuum degree in the plasma reaction chamber to a first value; Oxygen and argon gas are fed in and the vacuum degree is maintained; the cathode radio frequency frequency of the plasma reaction chamber is controlled to be 80-100KHz, and the anode radio frequency frequency is 30-35MHz to realize the first glow discharge. The invention can effectively clean the organic residues on the surface of the air spindle, thereby ensuring smooth and clean surface, reducing friction, improving working stability and precision and prolonging service life.

Description

technical field [0001] The invention relates to the field of numerical control machine tools, in particular to a polishing treatment method for an air spindle. Background technique [0002] The air spindle is an important part of the CNC machine tool. When it works, the compressed air enters the power shaft supported by the air bearing and is divided into two channels, one of which is used to drive the power shaft, and the other channel is used for the bearing seat to support the power shaft. Therefore, the cleanliness of the air shaft has a great influence on its precision. [0003] The traditional air spindle surface treatment method is to add cleaning fluid to the pool and use ultrasonic vibration to clean it. This method greatly improves the cleanliness of its air spindle, but there are residues on its surface anyway, such as cutting fluid, oil stains, and Surface scratches caused by careless replacement or insufficient compressed air. For CNC equipment, these residues...
