Our factory uses the 195 cylinder head cover (?) manufactured by Dalian Machine Tool Factory to automatically produce X195-03001, S195-030 (?) 195-03001 and S1100 cylinder heads. In the production, the verticality guarantee (?) of the conduit hole to the bottom plane was found, and the production quality was always unstable. In actual observation, it was found that the machining conduit hole and the gas (?) tool brought out a lot of chips, and the chips were not easily removed. If the coolant (?) was placed on the positioning pad (?), it was more difficult to remove. In the next work, if there is a little chip on the positioning horn, it will affect the verticality of the conduit hole.
