Wuhan Huayucheng CNC teaches you three measures to reduce the thermal deformation of CNC cutting machine cutting. Many friends who often deal with cutting machines often encounter the problem of cutting hot deformation of CNC cutting machines. This is not the case with CNC flame or plasma cutting machines. Regardless of the numerical control flame cutting or plasma cutting, since the cutting width is affected by various factors such as the cutting nozzle, no matter how high the precision of the equipment itself, the accuracy of the parts cut by the cutting is generally about ±0.5 mm. The error is several orders of magnitude higher than the device itself. That is to say, or with millions of imported CNC cutting machines, this can only be the case. So how to solve it? First of all, I want to say that this situation can't be avoided. Thermal cutting will definitely dissipate heat. It can only be said to reduce the occurrence of this situation. Below, Wuhan Huayucheng CNC teaches you three measures to reduce the thermal deformation of CNC cutting machine cutting.
First, after controlling the temperature rise, after taking a series of measures to reduce the heat source, the thermal deformation will be improved. The more effective method is to forcibly cool the heating part of the CNC plasma cutting machine tool, or to heat the machine in the low temperature department of the machine to make the temperature of the machine point uniform, which can reduce the warping deformation caused by the temperature difference. But to completely eliminate this problem is very difficult, so only by controlling the temperature rise to reduce the impact of heat. Because of the bilateral symmetry, the main axis of the double-column mechanism is slightly deformed in the other direction except for the vertical direction translation, and the vertical axis movement can be conveniently compensated by a coordinate correction amount.
Second, improve the machine tool mechanism, under the premise of the same fever, the machine tool mechanism also has a great influence on the thermal deformation. In the structure, the distance between the center of the main shaft and the main axial ground should be reduced as much as possible to reduce the total amount of thermal deformation. At the same time, the front and rear temperature rises of the main shaft box should be consistent to avoid tilting after the main shaft is deformed. This minimizes the effect of thermal deformation of the spindle on the machining diameter.
3. The heat source of thermal deformation caused by the fever inside the machine tool should be separated from the host. The thermal deformation of the shaft occurs in the vertical direction in which the tool is cut. For example, the single-column mechanism used in CNC machine tools in the past may be replaced by a double-column mechanism.
You should know more about this, regulate manipulation, and reduce the effects of possible thermal deformation. As a hot cutting processing equipment, CNC flame cutting machine may cause structural deformation due to temperature changes during frequent use.
