This machine is a numerically controlled and cross rail elevating double column type vertical boring and turning mill. Is a machine with two rail heads. One, on the right side is turning head and the other, on the left side is a milling head. The right head is utilized exclusively for turning work and can withstand heavy duty operation, and left performs boring and milling work. After the turning is completed, both heads can be performed without changing the machine set-up. These features, coupled with table indexing and milling feed, assure versatility machining capabilities. The cross rail is guided by the slideways of the two columns. Electro-hydraulic clamping clamping devices assure clamping of the cross rail at the desired position. Highly accurate horizontal straightness is guaranteed by the simple and stabilized method of utilizing the compensation beam inside the cross beam. ...
