Key Technologies Of Photopolymer Abrasive Tools

It is a new technology to make photopolymer abrasive tools in application field ofstereo lithography. Several essential technologies of making photopolymer abrasivetools were studied.(1) The performances of bonding agent of the photopolymer resin abrasive toolswere studied. The effects of different grain size, proportion and type of fillers for theperformance of the photopolymer resin abrasive tools were discussed with the hardnessand the mechanical intensity as conference. Furthermore the influence of the fillers forthe vitrification point of photopolymer abrasive tools was studied.(2) The bonding mechanics of the photopolymer abrasive tools was studied. Thebonding mechanics between the bonding agent and abrasives was analyzed with theparticular characteristics of the photopolymer resin comparing the classical theories.Some measures were carried out to improve the bonding ability between the bondingagent and the abrasives of photopolymer resin abrasive tools.(3) The curing mechanics of the photopolymer abrasive tools was studied. Theinfluence of the diamond grain and the fillers in the photopolymer abrasive tools on thecuring performance was discussed. A kind of photopolymer abrasive tool,photopolymer dicing blade was selected to analyze the curing mechanics of thephotopolymer abrasive tools. A mathematical model was developed to represent thecuring process of photopolymer dicing blade. The simulated data fit the experimentalresults, which demonstrated the analytical models and numerical algorithm were ofhigh reliability. The distribution of the light quantity inside the photopolymer abrasivetools was studied finally.(4) The processing characteristics and the abrasion mechanism of thephotopolymer abrasive tools were discussed. The necessity of conductibility of resindicing blade was introduced firstly, and then a suitable method to realize theconductibility of photopolymer dicing blade was found with metal plated diamondabrasives being used not only as abrasives but also as conductive fillers. Aim atdifferent processing materials and different dispensations; the processingcharacteristics of the photopolymer dicing blade were discussed with service life andcutting quality as reference. Furthermore the abrasion mechanism of the photopolymerresin dicing blade was analyzed by bonding agent and the abrasives respectively.Finally a cutting contrast test was preceded between the photopolymer dicing bladeand two kinds of like products.
