Description

Technical Field

[0001] The utility model mainly relates to the technical field of numerical control cutting, in particular to a small-diameter numerical control 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 very fast cutting speeds, and the cutting surface has a certain slope. Flame cutting machines are aimed at thicker carbon steel materials, and a small diameter cutting machine is required when cutting small diameter material pipes.

It is also impossible to adjust according to the pipe diameter and the required cutting length during the cutting process. Stopping back and forth to change materials and adjust is time-consuming and labor-intensive, resulting in low cutting efficiency. At the same time, when the pipe diameter is small, the fixation will be unstable, which can easily affect the cutting accuracy. Utility Model Content
