Abstract

The invention discloses a combined milling cutting processing device of a microstructure. The device comprises a laser and a fine milling cutter. The device is applicable to processing of a high depth-to-width ratio and complex long-route microstructure on a metal material or a nonmetal solid material. The invention also provides a combined milling cutting processing method of the microstructure.The method is characterized in that a workpiece to be processed is roughly processed to remove materials through a laser to obtain the microstructure, then the fine milling cutter is arranged at an inlet of the microstructure obtained by rough processing, and the fine milling cutter is driven to mill and cut the microstructure, and thus the final microstructure is obtained. With the adoption of the device and the method, the microstructure processing efficiency and processing accuracy can be improved; and meanwhile, the blade abrasion degree of the fine milling cutter is decreased, and the service life of the fine milling cutter is prolonged.

Description

technical field [0001] The invention relates to the technical field of micromanufacturing, in particular to a device and method for compound milling to process microstructures. Background technique [0002] Microstructures with a characteristic size of 0.01mm to 2mm are widely used in key parts of cutting-edge equipment in the fields of national defense, aviation, aerospace, energy and medical treatment. With the increasing maturity of micro-miniature technology, the development of micro-processing technology has been greatly promoted. The quality of the surface integrity of the microstructure directly affects the technical indicators related to the microstructure, such as electromagnetic, optical, vibration and fatigue. Structures, complex microstructures such as X-ray collimating gratings with a feature width of 0.01 mm to 1 mm for deep space exploration require high surface integrity. Many existing mature micromachining technologies, such as photolithography, microelectr...
