Description

Technical Field

[0001] This invention relates to the field of CNC machine tools, and more specifically, to an ultra-precision CNC machining tool with a self-feedback adjustment system. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. It can control the machine tool's movements by sending various control signals through a CNC device, and automatically process parts according to the shape and size required by the drawings. It is widely used in the production and processing of precision parts today.

[0003] In existing CNC machine tools, the temperature of the cutting head rises sharply during operation due to friction generated between the cutting head and the workpiece. To prevent the cutting head from burning out and to ensure its stability, a spray nozzle is usually installed inside the CNC machine tool to spray coolant to cool the working area of ​​the cutting head.

[0004] In existing CNC machine tool spray cooling devices, the amount of coolant sprayed is usually fixed. However, the actual temperature generated by the cutting head during operation is affected by the cutting power, and the actual demand for coolant by the cutting head is constantly changing. If the coolant is used in excessive amounts for a long time, it will easily lead to a reduction in the number of times the same batch of coolant can be recycled, resulting in unnecessary waste.

By filling the control tank fixed on the back of the cutting head with a medium, the medium can be driven to expand and contract according to the temperature feedback during the operation of the cutting head, thereby moving the piston. Through the tooth meshing connection between the rack and gear, the valve plate rotated inside the coolant supply pipe can be flexibly controlled.
