How to reduce the problem of thermal deformation of automatic cutting machine processing?
What methods can be used to reduce the problem of thermal deformation during cutting and machining? The following editor will tell you.
(1) Reduce heat and heat insulation. In order to reduce the heat of the machine tool in the process system, any heat source that may be separated from the host. Such as motors, gearboxes, screw pairs, fuel tanks, etc., should be placed outside the machine as much as possible. For parts and components that can separate the heat source, such as the main continent bearing, screw pair, wheel pair, friction clutch, etc., the friction characteristics should be improved from the structure and lubrication side to reduce heat generation.
(2) The heat of the cutting machine, so as to control the temperature rise and thermal deformation of the machine tool. For machine tools such as CNC machine tools and towel cores, freezers are commonly used to forcibly cool the lubricating oil, which greatly reduces the heating and deformation of the headstock components.
(3) Speed up the temperature rise and maintain the heat balance. The internal thermal deformation rule is known that after the cutting machine is sent to the thermal equilibrium during the pre-heating stage of the machine tool, the thermal deformation tends to be fixed, after which the machining accuracy can be guaranteed. Out of this, shortening the warm-up period of the machine tool is conducive to improving productivity and ensuring machining accuracy.
