我厂生产的打桩机机锤,其上、下汽缸体汽缸孔的粗镗和半精镗加工,原来是在C666车床上用长刀排镗孔。因为缸体孔径较大,孔深都在2米以上,需要先从一端车镗完半截缸孔,再将缸体调过头来,校圆后再完成另半截缸孔的加工,这样不仅劳动强度大,而且加工质量不易保证。为此,我们设计制造了一台 The hammer and semi-finishing machining of the cylinder bores of the upper and lower cylinder blocks of the hammer of the pile driver produced by our factory were originally used for the long knife row drilling on the C666 lathe. Because the cylinder bore diameter is larger, the hole depth is more than 2 meters. It is necessary to finish the half cylinder hole from one end of the car and then turn the cylinder over. After the rounding, the machining of the other half cylinder hole is completed. This is not only labor-intensive. Large, and processing quality is not easy to guarantee. To this end, we designed and manufactured a
