    摘要: A combined grinding and EDM apparatus has an indexable rotary turret with four work heads secured thereon to locate a pair of nozzle body blanks with their longitudinal axes in spaced parallelism; and either three or four compound cross and longitudinal slide assemblies carrying grinding tools, lapping tools or non-contact machining tools which work on the blanks to machine the face and to form a valve guide bore and a valve seat shaped as a frustrum of a cone whose axis is concentric with the bore, the valve seat cone surface having a small end diameter to large end diameter ratio in the order of 1-50.
