Micronano-sized micro hole machining tool

Abstract

The invention discloses a micronano-sized micro hole machining tool. The micronano-sized micro hole machining tool comprises a machining tool base, a cutting device, a multi-degree-of-freedom workbench system, a micronano microscope video system and a control system. The multi-degree-of-freedom workbench system is arranged on the machining tool base and comprises a workbench and a workbench driving device. The cutting device is arranged above the workbench. The micronano microscope video system is arranged on the machining tool base and located at one side of the multi-degree-of-freedom workbench system. The micronano microscope video system is used for performing image collection analysis on the machining process of workpieces on the workbench and transmitting collection analysis data to the control system. According to the micronano-sized micro hole machining tool, the micronano microscope video system is used for performing image collection analysis on the machining process of the workpieces on the workbench and transmitting the collection analysis data to the control system in time, the control system gives out control instructions to the cutting device and the multi-degree-of-freedom workbench system according to the collected workpiece machining information, and hence machining precision and finished product quality are improved.

Description

technical field [0001] The invention belongs to the technical field of hole processing machinery and equipment, and in particular relates to a micro-nano scale micro-hole processing machine tool. Background technique [0002] Hole processing occupies a large proportion in mechanical processing. According to statistics, hole processing accounts for about 30% of mechanical processing and 20% of the total processing time. With the rapid development of science and technology and industrial production such as aviation, electronics, instrumentation, precision machinery and automatic control, the application range of micro-holes is becoming wider and wider, and its processing requirements are gradually becoming stricter. [0003] In hole processing, micro hole processing is the most difficult, and the deep hole processing of micro holes is even more difficult. In general engineering, holes with a diameter below 3mm are called micro holes, and the ratio of hole depth to hole diamete...

AI Technical Summary

Problems solved by technology

The existing micro-hole drilling process has the following problems: the micro-drill has low rigidity, and the drilling position is easy to deviate, which seriously affects the accuracy of the drilling position and then affects the size and shape accuracy; because the hole diameter is small, it is difficult to remove chips and easily cause chips Blocking, increasing the heat and wear of the tool; the axial drilling force of ordinary drilling machines is relatively large, the burrs at the exit are relatively high, and its speed is not suitable for the processing of small apertures. To obtain a certain cutting speed, it must be equipped with corresponding tools. high-speed spindle, the production cost is greatly increased
