– The crossrail (W axis) could move upon the height of the work piece to increase the efficiency of machining, saves the production cost and expands the production range.

– The crossrail could be close to the work piece making sure the shortest extending length of the spindle increasing the performance of machining and extends the life time of the toolings.

– When ATC equipped, the command of tool change could be executed at any position, and the user can have several different choices of ATC numbers.

– Both crossrail and column are equipped with hydraulic locking system to ensure the crossrail and column match closest, high rigidity and high accuracy.
