1.加工设备的选用工程机械大量使用臂架类结构,例如起重机伸臂、挖掘机动臂等,镗孔需要保证较高的同轴度,各企业大多选择卧式双面镗铣加工中心进行加工(见图1),目前该设备多是直接采购国内外品牌机床,例如意大利FTP、日本三菱、意大利COLGAR以及沈阳机床等,该设备需要定期校验两根镗杆之间的同轴度,一般要求同轴度不得大于0.1mm,为提高加工的自动化程度,一般都
1. Selection of processing equipment Large number of construction machinery boom structure, such as crane boom, excavator boom, boring need to ensure a high degree of coaxiality, most companies choose horizontal double boring and milling machining center Processing (see Figure 1), the current equipment is mostly direct purchase of domestic and foreign brand machine tools, such as Italy FTP, Japan’s Mitsubishi, Italy COLGAR and Shenyang machine tools, the device needs to regularly check the degree of concentricity between the two boring bar, The general requirements of coaxiality shall not be greater than 0.1mm, in order to improve the degree of automation of processing, generally
