我厂生产的MDY-150采煤机每台有8个叶片4个端盘。由于内喷雾的需要,每个叶片(厚度28mm、直径1140mm)要求沿纵向加工φ12mm,深度400mm的等分深孔8～12个。过去,是在Z35摇臂钻上加工深孔,每次进程只有5～6mm,每钻一个孔钻头需反复65～70次,不仅效率极低,而且完全靠人工控制,保证不了孔的垂直度和孔壁厚度。为解
MDY-150 Shearer produced by our factory has 4 blades of 8 blades each. Due to the need of internal spray, each blade (28mm in thickness and 1140mm in diameter) requires the processing of 8 to 12 boreholes with a diameter of φ12 mm and a depth of 400 mm in the longitudinal direction. In the past, Z35 rocker drilling deep hole processing, each process is only 5 ~ 6mm, drill a hole for each drill to be repeated 65 to 70 times, not only inefficient, but also completely by manual control, can not guarantee the verticality of the hole And hole wall thickness. To solve
