Double-wire annular diamond fretsaw horizontal cutting method and numerical control jade fretsaw machine

Abstract

The invention discloses a double-wire annular diamond fretsaw horizontal cutting method and a numerical control jade fretsaw machine. The numerical control jade fretsaw machine is provided with a first cutting loop wire and a second cutting loop wire to conduct feeding simultaneously to cut a to-be-cut workpiece fixed to a rotating platform, two annular diamond fretsaws in the numerical control jade fretsaw machine are driven by a first cutting driving wheel train and a second cutting driving wheel train correspondingly, and the two annular diamond fretsaws control cutting tension force through tension adjusting devices correspondingly, the first cutting driving wheel train and the second cutting driving wheel train are arranged on a Z-axis lifting adjusting platform capable of being controlled through a numerical control program, and the parallel distance between the two annular diamond wires in the vertical direction can be adjusted through a distance adjusting platform arranged on the Z-axis lifting adjusting platform. According to the method and the fretsaw machine, the cutting efficiency can be greatly improved, the wire diameter of the annular diamond fretsaw is small, the workpiece cutting loss is small, and the risk that a workpiece is collided to be damaged during cutting machining is greatly reduced through a horizontal cutting method, which is particularly suitable for cutting precious crisp and hard materials.

Description

technical field [0001] The invention relates to the technical field of diamond wire saw equipment, in particular to a double-wire annular diamond wire saw flat cutting method and a numerically controlled jade wire saw machine. Background technique [0002] A diamond wire saw is a cutting tool with diamond abrasive fixed on a wire. Diamond wire saws are often used for slicing monocrystalline silicon rods, polycrystalline silicon ingots, and silicon wafers, sapphire crystal rods, slicing, silicon carbide and other difficult-to-cut materials, various substrate cutting, crystal, ceramics, Jade cutting and other fields. Diamond wire saws in the prior art mostly use a very long single-wire diamond wire saw for cutting. This kind of long single-wire diamond wire saw needs to take up the wire at the same time when cutting, so the speed of the wire saw cannot be high during cutting, and its cutting efficiency is low; moreover, it is troublesome and time-consuming to replace the dia...

AI Technical Summary

Problems solved by technology

However, this kind of diamond wire saw cutting equipment usually adopts vertical downward cutting for processing. For some brittle and hard materials with irregular shapes such as natural jade, the workpiece is not easy to fix when cutting vertically, and the workpiece is easy to fall after cutting. Bumping; and only one cutting surface can be processed at a time during cutting, and there is still room for improvement in its processing efficiency
