Now, many users will encounter thermal deformation when using the laser cutting machine. If it cannot be solved well, the cutting accuracy will be reduced, so we all hope that there can be some ways to reduce its thermal deformation. Let's share:

Customers who often deal with cutting machines often encounter the problem of thermal deformation of laser cutting machines. CNC flame or plasma cutting machines, no matter CNC flame cutting or plasma cutting, because the width of cutting edges is affected by many factors such as cutting nozzles, no matter how high the accuracy of the equipment itself is, the accuracy error of the parts cut with it is generally about ± 0.5mm, which is several orders of magnitude higher than the equipment itself.

Even if millions of imported laser cutting machines are used, how can we solve this problem? First, this is unavoidable. Thermal cutting certainly emits heat. It can only be said to reduce the occurrence of this situation. Big picture laser teaches you three ways to reduce the thermal deformation of laser cutting machine.

1、 After controlling the temperature rise and taking a series of measures to reduce the heat source, the thermal deformation will be improved. A more effective method is to force cooling in the heating part of the CNC plasma cutting machine tool, or heating in the low temperature part of the machine tool to make the temperature of each point of the machine tool uniform, which can reduce the warpage caused by the temperature difference.

But it is very difficult to completely eliminate this problem, so the only way to reduce the impact of heat source is to control the temperature rise. Because of the symmetry between left and right, the main shaft of the heated double column mechanism will not deform in the direction other than the vertical movement, and the movement of the vertical axis can be easily compensated by coordinate correction.

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

We should learn more about this knowledge, standardize the operation, and reduce the influence of possible thermal deformation. As a thermal cutting equipment, CNC flame cutting machine may cause structural deformation due to temperature change during frequent use and processing.

3、 To improve the machine tool mechanism, under the same premise of fever, the machine tool mechanism also has a great impact on thermal deformation. In this structure, the distance between the center of the spindle and the spindle towards the ground should also be reduced as much as possible to reduce the total amount of thermal deformation. At the same time, the temperature rise of the spindle box should be consistent before and after, so as to avoid the tilt of the spindle after deformation. This minimizes the effect of thermal deformation of the spindle on the machining diameter.

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