二汽铸造二厂进口的BMD自动铸造线,连接小车只进口一台样机,小车与小车零什“球面轴承”,原安排在保定铸造机械厂试制,因球面轴承制造工艺上有困难,将原结构改成两半装配而成,而且采用青铜材料制成,制造出的产品不符合使用要求。上级将此任务安排在我厂机具车间试制,车间组成了球面工艺攻关队,经过大量试验研究,终于发现了轴承
Second Auto Casting Plant imported BMD automatic casting line, connecting the car only to import a prototype, the car and the car zero “spherical bearings”, the original arrangement in Baoding foundry machinery trial production due to spherical bearing manufacturing difficulties, the original The structure has been changed to two halves assembled and made of bronze material to create a product that does not meet the usage requirements. Supervisor will arrange this task in my factory workshop prototype, the team formed a spherical craft attack team, after a large number of experimental studies, finally found the bearings
