Hydraulic cylinder, mining single pillars, hydraulic supports, gun barrels leh thil dang te component ber a nih angin, a processing quality hian direct takin product pumpui nun leh rintlakna a nghawng a ni. Cylinder-a processing mamawh chu a sang hle a, a chhung lam roughness mamawh chu RA0.4~0.8&um a ni a, coaxiality leh wear resistance pawh khauh takin a ngai a ni. Cylinder-a thil pawimawh ber chu deep hole processing a ni a, a processing hian processing personnel-te a tibuai fo thin.
Rolling process chu hman a ni. Surface layer hian surface-ah residual compressive stress a neih avangin surface micro cracks khar nan leh erosion expansion a tikhawtlai thei a ni. Chutiang chuan surface corrosion resistance a ti tha a, fatigue crack siam emaw, tihpun emaw a tikhawtlai a, chu chuan cylinder-a fatigue strength a ti tha zawk a ni. Rolling forming hmangin rolling surface-ah hian cold work hardening layer a lo awm a, chu chuan grinding pair-a contact surface elastic leh plastic deformation a tihziaawm a, chu chuan cylinder chhunga wall-a wear resistance a ti tha a, grinding avanga kangmei chhuak tur a veng bawk. Rolling hnuah chuan surface roughness value tihhniam hian matching property a ti tha thei a ni.
Engineering machinery-a thil pawimawh ber chu oil cylinder a ni. Traditional processing method chu: cylinder body chu drawing la-Cylinder body chu precision boring rawh-cylinder body griding. A rolling dan chu: cylinder body broaching - fine boring cylinder body - rolling cylinder body. A kalphung chu hmun 3 a ni a, mahse hun inthlauhna chu: cylinder taksa meter 1 grinding hian ni 1-2 vel a awh a, cylinder body meter 1 vel chu minute 10-30 vel a ni. Investment tehkhin dan: Grinder emaw honing machine (sang tam tak atanga maktaduai tam tak), rolling cutter (1,000 atanga sang tam tak) te. Rolling hnuah chuan RA3.2~6.3um atanga RA3.2~6.3um atanga RA0.4~0.8&um-a a chung lam roughness chu a tlahniam a, chu hole surface hardness chu 30% velin a sang a, cylinder chhung lam fatigue strength chu 25% in a sang bawk. Cylinder-a nghawng chauh ngaihtuah a nih chuan cylinder service life chu vawi 2~3-in tihpun a ni a, boring leh rolling process chu grinding process aiin a let 3 velin a thawk tha zawk a ni. A chunga data kan tarlan te hian rolling process a tha a, cylinder surface quality nasa takin a ti tha thei tih a tarlang.
Rolling hnuah chuan cylinder chunglamah hian sharp tiny edge a awm lo va, long{0}}Term movement friction hian seal ring emaw seal emaw a tichhia lo ang a, hei hi hydraulic industry-ah chuan a pawimawh hle.
