半成品,由于我打算在缺少焊接铝的专业机器的情况下,用我的小型CNC把细节全部加工出来,并且使用螺栓连接全部部件,到后面权衡再三感觉加工成本太高了,我的加工技术也不是那么好,一个部件重复多次打表再加工对我来说太耗时间和金钱了,逐放弃,打算以后有机会再完善,或者另起炉灶 Semi-finished product. Since I didn't have a professional machine for welding aluminum, I planned to use my small CNC to process all the details and use bolts to connect all the parts. Later, I weighed the pros and co and felt that the processing cost was too high. My processing technology is not that good. Repeatedly marking and processing a part is too time-couming and costly for me. I gave up and planned to improve it later or start a new business.
