Embodiment Construction

[0036] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0037] The invention relates to a method for repairing main rollers of an NTC multi-wire cutting machine. Such as image 3 As shown in A, A represents the worn main roll to be repaired, and wear occurs at the tapered hole. The repair method of NTC multi-wire cutting machine master roll of the present invention comprises the following steps:

[0038] (1) Shaft head removal: Use a special tool to remove the shaft head with a tapered hole of the main roller to be repaired, and process the end face of the roller body formed after removing the shaft head into a new end face perpendicular to the outer peripheral surface of the roller body to form two ends Roller bodies w...

Abstract

The invention discloses a repair method of an NTC multi-wire sawing machine main roller and a main roller structure after repair. The repair method comprises the steps of shaft head removal, clamping hole machining, novel shaft head machining, mechanical fixing and the like. The reutilization of the NTC multi-wire sawing machine main roller is achieved with low investment, and the economic loss brought by conical surface abrasion is minimized. The repair method and the main roller structure have great economic value.

Description

technical field [0001] The patent of the present invention relates to the technical field of multi-wire cutting machine, in particular to a method for repairing the main roller of NTC multi-wire cutting machine and the structure of the repaired main roller, which can be used for silicon wafer cutting, sapphire wafer cutting, ceramic material cutting, etc. . Background technique [0002] At present, the photovoltaic multi-wire cutting technology mostly uses the main roller to support the wire mesh and cooperate with the mortar to cut semiconductor crystals, such as silicon wafers. Among them, Japan's Komatsu NTC is an important equipment manufacturer of multi-wire cutting machines. It is famous for its superior performance, high adaptability and simple operation of photovoltaic multi-wire cutting machines, especially in the field of monocrystalline silicon wafer cutting. At present, there are more than 3,000 NTC slicers in China, among which MWM442, PV600, and PV800 are the ...
