Description

Technical Field

[0001] The invention relates to the field of cutting structures, and in particular to a precise positioning double-wire cutting machine. Background Art

[0002] With the development of modern mechanical processing industry, the requirements for cutting quality and precision are constantly increasing, and the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also increasing. The development of CNC cutting machines must adapt to the requirements of the development of modern mechanical processing industry. Cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines, water cutting machines, etc. Laser cutting machines are the most efficient, with the highest cutting accuracy and generally smaller cutting thickness. Plasma cutting machines also have a very fast cutting speed, and the cutting surface has a certain slope. Flame cutting machines are aimed at thicker carbon steel materials.

[0003] Gas can be a lubricant just like oil, and the physical laws of fluid dynamic lubrication also apply to gas. The viscosity of gas is very low, which means that its film thickness is also very thin. Therefore, fluid dynamic gas bearings (gas dynamic bearings) are only suitable for high speeds, light loads, small clearances and very strict tolerance control. For this reason, gas static bearings are generally more commonly used, which can withstand higher loads, have less stringent requirements on clearances and tolerances, and can also be used at lower speeds, even at zero speed.

[0004] Advantages: Gas lubrication can be used at higher or lower temperatures than lubricating oil and grease, and can lubricate sliding bearings in the range of -200℃-+2000℃. Its friction coefficient is so low that it cannot be measured, and the bearing stability is very high. High rigidity can be obtained in high-speed precision bearings (such as medical dental drills, precision grinding machine spindles, and inertial navigation gyroscopes, etc.), and there are no sealing and contamination problems.

[0005] After the cutting device cuts the profile, its surface needs to be cleaned and lubricated. To this end, we use the above characteristics to design an integrated device to cut the workpiece and clean and lubricate the workpiece after cutting. Summary of the invention
