Problems solved by technology

[0003] However, the temperature control accuracy of the existing machine tool oil cooling system is not high, because too much cooling oil bypass will lead to insufficient heat exchange of the refrigerant in the evaporator, causing the compressor to suck liquid, which will affect the reliable operation of the machine tool. Reduced service life of machine tools

Abstract

The invention provides a machine tool oil cooling system. The cooling system comprises a machine tool, a refrigerating device, a cooling device, a first condenser, a hydraulic valve part and a direct-current fan assembly. One end of the machine tool is connected with the refrigerating device; the other end is connected with the cooling device; the refrigerating device is connected with the coolingdevice; one end of the hydraulic valve part is connected with the refrigerating device; the other end of the condenser is connected with the first condenser, the first condenser is connected with therefrigerating device, and direct-current fan assembly is fixed to one side of the first condenser. According to the machine tool oil cooling system, the temperature control precision of cooling oil can be effectively improved, the machining precision of machine tool equipment is improved, meanwhile, the reliability of the cooling equipment is improved, and the service life of the machine tool isprolonged.

Description

technical field [0001] The invention relates to the technical field of cooling control, in particular to a machine tool oil cooling system and a control method thereof. Background technique [0002] In modern manufacturing, machine tools are indispensable equipment, such as CNC (Computer Numerical Control, digital control machine tools), grinding machines, wire cutting machine tools and so on. When the machine tool is working, the high-speed operation of the cutting tool and the spindle will generate a lot of heat, which will cause thermal deformation of the guide rail and the spindle of the machine tool, thereby reducing the machining accuracy of the workpiece and reducing the life of the tool and the spindle. Therefore, there is a need to cool the machine tool. The role of machine tool coolers such as oil coolers (also known as oil coolers) is to effectively reduce the heat generated by machine tool cutting. [0003] However, the temperature control accuracy of the exist...
