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

Abstract

The invention discloses a spiral waveform cutting metal wire as well as a manufacturing method and equipment thereof. The metal wire is a spiral waveform metal wire formed by rotating a periodic waveform metal wire along an axial center line, a wave crest and a wave trough of the metal wire are distributed along the axial center line, and a spiral diameter of the metal wire is equal to a wave height. The spiral waveform cutting metal wire disclosed by the invention can provide better mortar abrasive carrying capability in the process of cutting a rigid material through a stereostructure of the spiral waveform cutting metal wire, and the abrasive is not easily stripped from a cutting wire, therefore, the production speed and efficiency of technical processing of cutting and slicing silicon materials, precious stones and the like are greatly improved, and the surface quality of the sliced materials can be also improved.

Description

technical field [0001] The invention relates to a cutting wire, a manufacturing method and equipment, in particular to a spiral wave cutting wire and a manufacturing method and equipment. 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, gemsto...
