Abstract
The present disclosure relates to a machine tool, such as a moving column-type machining center, and a method of operating the same, which are capable of shortening tool change time, improving productivity, minimizing a collision or mechanical interference, and increasing stability and reliability in a medium-sized or large-sized machine tool having a long length in a width direction by means of a magazine installed on a saddle, a tool changing unit movably installed on the saddle, and a tool changing unit transfer part configured to move the tool changing unit independently of a column.
Claims17
A machine tool comprising:
- a bed;
- a table installed on the bed, the table being configured to allow a workpiece to be seated thereon for machining;
- a saddle movably installed on the bed, the saddle being movable on the bed in a first linear direction;
- a column movably installed on the saddle, the column being movable on the saddle in a second linear direction, the second linear direction extending perpendicular to the first linear direction;
- a spindle movably installed on the column, the spindle being configured to machine the workpiece, the spindle being movable on the column in a third linear direction, the third linear direction extending perpendicular to both the first linear direction and the second linear direction;
- a tool magazine having a plurality of grippers, the plurality of grippers being configured to accommodate tools that are to be supplied to the spindle;
- a transferer configured to move the saddle, the column, and the spindle;
- and
- a tool changer movably installed on the saddle, the tool changer being movable on the saddle in the second linear direction and being movable on the saddle through an opening of the column such that the tool changer replaces a first tool mounted on the spindle with a second tool accommodated in one of the plurality of grippers of the tool magazine,
- wherein the tool magazine is installed on the saddle and moves together with the saddle when the saddle moves.
