Abstract
A machine tool comprises a base with an upstanding column, a vertical spindle axis tool driving unit symmetrically located and vertically movable on the front of the column, a frontwards oriented horizontal spindle axis tool driving unit symmetrically located and vertically movable extending through the column, and a pair of guiding rails to extend vertically thereon and horizontally spaced apart from each other for guiding the upward and downward movement of the tool driving units. Symmetrically disposed counterbalance weights for both tool driving units are located within the column. Independent leadscrew driving means provide vertical upward and downward movement of the tool driving units.
Claims18
A machine tool for chipmaking and grinding machining operations comprising:
- a base;
- a column fixed to said base;
- guiding rails fixed in reference to the column for directing the generally linear upward and downward movement of spindle carriers with respect to the column;
- a first spindle carrier slidably carried on said guiding rails wherein a tool driving spindle with a vertical axis of rotation is rotatably carried;
- a second spindle carrier slidably carried on said guiding rails wherein a tool driving spindle with a horizontal axis of rotation is rotatably carried;
- driving means for moving said spindle carriers upwardly and downwardly;
- independent counterbalancing means for each spindle carrier;
- driving means to impart rotation to the tool driving spindles;
- whereby machining operations can be carried out in mutually perpendicular planes.
