Nowadays, many users encounter thermal deformation during the use of laser cutting machines. If it cannot be solved well, it will reduce the cutting accuracy, so everyone hopes to have some methods to reduce its thermal deformation. Let's share with you:

Customers who often deal with cutting machines often encounter thermal deformation problems with laser cutting machines. For CNC flame or plasma cutting machines, regardless of CNC flame or plasma cutting, the width of the cutting edge is affected by many factors such as cutting nozzles. Therefore, regardless of the accuracy of the equipment itself, the accuracy of the parts cut with it is generally within ± 0.5mm, which is several orders of magnitude higher than the height of the equipment itself.

Even using millions of expensive imported laser cutting machines can only do this, so how to solve it? First of all, this situation is inevitable. Thermal cutting definitely emits heat. It can only be said to reduce the occurrence of this situation. Large image laser teaches you three ways to reduce thermal deformation during laser cutting.

1、 After controlling temperature rise and taking a series of measures to reduce heat sources, thermal deformation will be improved. A more effective method is to force cooling in the heating section of a CNC plasma cutting machine tool or heating in the low-temperature section of the machine tool to equalize the temperature at various points of the machine tool, which can reduce the warpage caused by the temperature difference.

However, it is very difficult to completely eliminate this problem, so the only way to reduce the impact of heat sources is to control the temperature rise. Due to the symmetry between the left and right sides, the main shaft of the heated double column mechanism hardly deforms in directions other than vertical movement, and coordinate correction can easily compensate for the movement of the vertical axis.

2、 The heat source of thermal deformation caused by heating inside the machine tool should be separated from the main body. Thermal deformation of the shaft occurs in the vertical direction of the cutting tool. For example, the single column mechanism used in CNC machine tools in the past can be replaced by a double column mechanism.

You should learn more about this knowledge, standardize operations, and reduce the impact of possible thermal deformation. As thermal cutting processing equipment, CNC flame cutting machines may cause structural deformation due to temperature changes during frequent use and processing.

3、 Improving machine tool mechanisms also has a significant impact on thermal deformation under the same fever condition. In this structure, the spacing between the center of the main shaft and the ground of the main shaft should also be minimized to reduce the total amount of thermal deformation. At the same time, the temperature rise of the main shaft box should be consistent before and after deformation to prevent the main shaft from tilting. This can minimize the impact of thermal deformation of the spindle on the machining diameter.

You can operate according to the above article to reduce the thermal deformation of the fiber laser cutting machine, and do not worry too much later.
