Metal cutting wire with spiral wave-shaped rotary bending parts

Abstract

The invention discloses a metal cutting wire with spiral wave-shaped rotary bending parts. The metal cutting wire is provided with a plurality of spiral wave-shaped rotary bending parts along a central axis. According to the metal cutting wire with the spiral wave-shaped rotary bending parts, better capability of carrying mortar grinding materials in the hard material cutting process can be provided through a three-dimensional structure, and the grinding materials are unlikely to strip from the cutting wire so that the production speed in the cutting and fragmenting process of silicon, jewel and the like is greatly increased, the production efficiency in the cutting and fragmenting process of silicon, jewel and the like is greatly improved, and the surface quality of the fragmented materials also can be effectively improved at the same time. The speed of the grinding materials in the abrasion cutting process of hard materials is reduced relative to that of the metal cutting wire, so that the abrasion degree of the metal cutting wire is reduced.

Description

technical field [0001] The invention relates to a cutting wire, in particular to a cutting wire with a composite rotating waveform. Background technique [0002] In the division and slicing process of hard materials such as monocrystalline silicon, polycrystalline silicon, and gemstones in the field of electronics and solar energy, the most used method is to use linear metal monofilaments to move in one direction or reciprocating under a certain tension. way to split slices. When the metal monofilament is moving, through the mortar transportation and injection system, before the metal monofilament contacts with the silicon rod and other objects to be cut, the mortar containing extremely hard abrasive particles is sprayed on the metal monofilament, and the metal monofilament is brought into the cutting process. Through the continuous grinding process of extremely high hardness abrasive particles and silicon rods, gemstones and other objects to be cut, the cutting and slicing...

AI Technical Summary

Problems solved by technology

[0003] The linear metal monofilament can only be mechanically brought into the mortar through the smooth surface at high speed, and during the cutting process, the abrasive in the mortar is easy to peel off from the cutting wire, which affects the cutting speed and slice quality, resulting in the cutting process. Silicon materials, gemstones and other hard materials are likely to cause metal monofilament breakage, silicon materials, gemstones and other hard materials such as line marks on the surface of slices and other quality or process problems
