A Brief Analysis of Diamond Wire Loop Cutting Technology

In the processing of high-precision components made from hard and brittle materials, cutting plays a crucial role on the equipment. Hard and brittle materials belong to difficult-to-process materials, and cutting, as the first step in material processing, affects the quality of subsequent processes and even influences the ultimate service life of the product.

In order to meet the requirements of high quality, high eficiency and low loss cutting of hard and brittle materials, the machining technology of hard and brittle materials was studied.

The mechanism of cutting hard britle materials based on britle fracture mechanics theory, the indentation crack growth process, proved that the hard brittle materials can realize the plastic removal under certain conditions, and discuss the critical condition of brittle ductile transition.

According to the shape. size and distribution of particles of diamond wire, a hard brittle material of diamond wire cutting geometry model, the average cuting depth of diamond wire section of single particle and single particle of actual cutting depth is calculated, and the diamond wire cutting eficiency were analyzed and provide a theoretical basis for cutting hard brittle materials with high quality and high efficiency.

According to the requirement of hard brittle material of small diameter precision plane cutting technology, machine tool development process using TOP-DOWN correlation design method, put forward high precision diamond circular wire saw HGJ-200 overall design scheme,

including control device loop feed system, process, cutting machine manufacturing diamond wire cutting ring frame, constant tension. Based on the finite element analysis method of Solidworks Simulation, the static and dynamic characteristics ofthe key parts ofthe machine tool are analyzed, and the structure of the machine tool is optimized. In order to guarantee a high cutting precision.

systematic research on manufacturing, assembly and measurement process of the machine, thewhole assembly process of strict implementation of` precision and ultra precision machine tool
