Automatic machining system and method for crystal growing furnace rack

The invention discloses an automatic machining system and method for a crystal growing furnace rack. The system comprises a cutting machine, a steel pipe perforating machine, a plate cutting machine,a deburring machine, a welding machine, and a shot blasting machine, wherein the cutting machine is used for cutting a square steel pipe into a plurality of short pipes; the steel pipe perforating machine is used for positioning and perforating the cut short pipes; the plate cutting machine is used for cutting the steel plate into a plurality of small plates; the deburring machine is used for carrying out deburring operation on the cut small plates; the welding machine is used for welding the short pipes and the small plates to form a rack; and the shot blasting machine is used for carrying out shot blasting treatment on the welded rack. According to the system, complete precision of a drilling position on the steel pipe is achieved, then the situation that the drilling position on the steel pipe deviates is effec
