Description
Technical field
The present invention relates to diamond wire production technical field, particularly a kind of producer of high-bond resin diamond wireMethod.
Background technology
At present, in photovoltaic field, monocrystalline silicon and polysilicon are one of conventional raw materials, at present domestic the most frequently usedThe method of cutting silicon be the free mortar scroll saw of application SiC,, in cutting process, SiC abrasive material is joinedBetween metal wire and workpiece, produce shear action, because abrasive material is in free state, need to lean on the band of steel wireMoving, therefore stock-removing efficiency and cutting precision are lower, and steel wire can contact with silicon ingot in working angles,Can cause like this wearing and tearing of steel wire and silicon ingot to occur cut, directly affect the life-span of steel wire and the quality of silicon chip.
In order to address the above problem, fixed-abrasive wire saw receives much concern, and is diamond abrasive grain by certainEquipment and process is bonded to a kind of cutting element that the surface of stainless steel wire forms. This kind of scroll saw is due to abrasive particleBe cemented in the surface of stainless steel wire, in the process of cutting, the free degree of abrasive particle is very little, can exist more regularlyUnder the drive of stainless steel wire, carry out cutting operation, improved cutting accuracy and efficiency, simultaneously due to stainless steel wireWrapped up by abrasive particle, so stainless steel wire can be worn hardly, improved the service life of whole scroll saw.
Conventionally diamond is attached to the scroll saw on steel wire by the mode of resin-bonding by diamond, is called resinDiamond fretsaw (referred to as resin diamond wire). This resin diamond wire, compared with electroplating Buddha's warrior attendant scroll saw, has disconnectedThe advantages such as the silicon chip surface cutting damage that line rate is low, less and less gross thickness fluctuation, therefore extensively shouldFor fields such as semiconductor, photovoltaic industries.
But resin diamond wire resinoid bond used, owing to existing Steel Wire Surface cohesive force low, can cause treeFat layer and diamond abrasive grain entirety come off, and finally expose steel wire, can produce broken string, now need to change gauze,Thereby cause silicon ingot finished product bad, increased use cost, greatly reduce cutting efficiency.
