【Abstract】 Shearer cutter often crack and break when they are working under the force. Through the study of cutter in long-time. Analyze the force on the cutter body and hard alloy head, and offer the method and formula of its strength proofreading. It`s very important to proofread the strength when we design shearer cutter.更多还原
