  • Machining method and machining apparatus of valve holes of cylinder head, and clamp device
    Patent number: 10052697
    Abstract: Two cylinder heads are disposed side by side. Upper side intake valve holes of one of the cylinder heads and upper side exhaust valve holes of the other of the cylinder heads are simultaneously machined by a multi-spindle head integrally including intake side tools and exhaust side tools. After moving the one of the cylinder heads upward by a pitch of the intake valves and moving the other of the cylinder heads upward by a pitch of the exhaust valves, remaining intake valve holes of the one of the cylinder heads and remaining exhaust valve holes of the other of the cylinder heads are simultaneously machined.
    Type: Grant
    Filed: August 7, 2015
    Date of Patent: August 21, 2018

  • Machining method and machining apparatus of valve holes of cylinder head, and clamp device
    Patent number: 9114495
    Abstract: Two cylinder heads (3, 3) are disposed side by side. Upper side intake valve holes (34a, 34c, 34e, 34g) of one of the cylinder heads (3) and upper side exhaust valve holes (35a, 35c, 35e, 35g) of the other of the cylinder heads (3) are simultaneously machined by a multi-spindle head (24) integrally including intake side tools (26a to 26d) and exhaust side tools (28a to 28d). After moving the one of the cylinder heads (3) upward by a pitch P1 of the intake valves and moving the other of the cylinder heads (3) upward by a pitch P2 of the exhaust valves, remaining intake valve holes (34b, 34d, 34f, 34h) of the one of the cylinder heads (3) and remaining exhaust valve holes (35b, 35d, 35f, 35h) of the other of the cylinder heads (3) are simultaneously machined.
