图1是制糖机真空煮糖缸的一个主要零件;規格是φ4300×25毫米,上面有φ102孔625个。由于要求每对管板孔同孔之間的位置应当同心,以保証无縫鋼管的装配質量,所以这个零件的加工就成了很大的难题。这些孔原来是在搖臂钻床上加工出來的,但在加工过程中发生了很多問题,而且效率低,加工一个孔需40分鐘。这个問題好象一块鉛块似的老擱在电焊工黄平同志的心里。他经过苦心钻研,終于制成一台半自动切割机。結
Figure 1 is a sugar machine vacuum cooker tank a major component; specifications are φ4300 × 25 mm, above the φ102 hole 625. Because of the requirement that each pair of tube plate holes should be concentric with each other to ensure the assembly quality of seamless steel tubes, the machining of this part becomes a big problem. These holes were originally machined on a radial drilling machine, but many problems occurred during the machining process and were inefficient, requiring 40 minutes to process one hole. This question seems to be a piece of lead-like old rest in the heart of welder Huang Ping. After painstaking research, he finally made a semi-automatic cutting machine. Knot
