Problems solved by technology

The traditional mechanical grinding process of ntD micro-tools is prone to pits due to grain damage, which seriously affects the processing quality of the tool; at the same time, the efficiency of traditional mechanical processing of superhard material nano-twinned diamond is too low. In order to realize the industrial application of nano-twinned diamond At present, it is urgent to explore a manufacturing and processing technology and efficient molding process of nano-twinned diamond micro-tools.

Abstract

The invention relates to a machining method for quickly forming a nanometer twin-crystal diamond micro cutter. The machining method comprises the following steps: brazing an ntD block material onto ahard alloy cutter handle, then placing the welded ntD cutter handle on an experimental machining platform with five degrees of freedom, then using femtosecond laser with a galvanometer to carry out parallel rough machining on a rear cutter surface and a front cutter surface of the ntD block material on the experimental machining platform step by step, and then using femtosecond laser without a galvanometer to carry out parallel finish machining on the rear cutter surface and the front cutter surface of the ntD micro cutter formed after machining in the above step according to the sequential order until the nanometer twin-crystal diamond micro cutter meeting the requirement is obtained. The machining method is high in machining quality and high in efficiency.

Description

technical field [0001] The invention belongs to the processing field of nano-twinned diamond micro-cutters, in particular to a processing method for rapid prototyping of nano-twinned diamond micro-cutters. Background technique [0002] Nanotwinned Diamond (ntD) is a newly synthesized superhard material in recent years, with a Vickers hardness of 220GPa, which is nearly twice the hardness of single crystal diamond (Single Crystal Diamond, SCD). Nano-twinned diamond has the characteristics of anisotropy and no cleavage, and has the advantages of excellent thermal conductivity and good wear resistance in terms of physical properties. Combining the above advantages, the emerging superhard material of nano-twinned diamond will replace the industrial status of single crystal diamond and polycrystalline diamond in the application of ultra-precision machining and aerospace. The traditional mechanical grinding process of ntD micro-tools is prone to pits due to grain damage, which se...
