Patent: a polysilicon block cutting device
Full thread studs are special grade bolts, represented by material grades. Material substitution for chemical equipment must be confirmed by design before it can be represented. Once, it was seen on site that Grade 4.5 hexagonal bolts were used instead of Grade 8.8 bolts Fully Threaded Stud,B7 Full Thread Studs,Pressure Resistant Screws,High Strength Fully Threaded Studs AM FASTENER , https://www.asmefastener.com

Abstract: The utility model discloses a polycrystalline silicon block cutting device. Mainly include adjustable knife holder, fixed knife holder, pitch control screw, pitch guide rail, work table, bed and so on. The equipment consists of two electroplated diamond wire saws. The two electroplated diamond wire saws are respectively mounted on the wheel of the adjustable knife holder and the fixed knife holder. The position of the electroplated diamond wire saw 2 is fixed, and the electroplated diamond wire saw is along The length of the polycrystalline silicon chunks can be adjusted so that polycrystalline silicon chunks of different impurity regions can be processed. In the working process, the two electroplated diamond wire saws can simultaneously cut the head and tail parts of the polycrystalline silicon block, so that the worktable can complete the cutting and removing work of the polysilicon block head and tail at the same time with one feeding, reducing the number of workpiece clamping and improving Cutting efficiency and cutting quality.
