Abstract
A moving beam type machine tool is disclosed, having a dynamic phase balancing weight set and a spindle saddle. The spindle saddle has at least one X-axis location feedback device. When the spindle saddle along the X-axis traverse, the at least one X-axis location feedback device is able to locate the spindle saddle and inform a controlling unit. The controlling unit changes the output pressure of the dynamic phase balancing weight set depending on the location of the spindle saddle, so that a crossbeam is able to maintain in a balancing state. The moving beam type machine tool is able to increase accurate, sensitivity of pressure response, withstanding weight and balancing state.

A moving beam type machine tool, comprising:
- a machine table, having an X-axis direction, a Y-axis direction and a Z-axis direction defined thereat according to a Cartesian coordinate system;
- a column, disposed perpendicular to the X-axis direction at an end of the machine table;
- a crossbeam, moveably mounted on the column in a direction parallel with the X-axis direction while being enabling to move in a reciprocating manner following the Z-axis direction;
- a spindle saddle, movably mounted on the crossbeam and capable of moving in a reciprocating manner following the X-axis direction;
- a spindle head, rotatabley coupled to the spindle saddle;
- and
- a dynamic phase balancing weight set, disposed at two opposite ends of the crossbeam;
- wherein, in a condition that when the spindle saddle is moved in the X-axis direction approaching to the dynamic phase balancing weight set, the output pressure resulting from the dynamic phase balancing weight set is increased, and when the spindle saddle is moved in the X-axis direction away from the dynamic phase balancing weight set, the output pressure resulting from the dynamic phase balancing weight set is decreased, and thereby, the balance of the crossbeam is maintained.
