A machining device including a framework, a transmission shaft and a drive mechanism including a rotation member for driving the shaft in rotation about its axis, a drive member in helical connection with the shaft to drive the translation thereof along its axis with a feed movement, according to the relative rotational speed of the rotation and drive members. The drive member is mounted with the ability to effect translational movement with respect to the framework along the axis and is positioned between the rotation member and an end for coupling of the shaft to a cutting tool, while an electromechanical actuator is mounted in a fixed frame of reference associated with the framework in front of the drive member to which it can be coupled in order to cause it to oscillate translationally so as to superpose an axial oscillation component with the feed movement.

According to an embodiment of the present invention, a torque variation of a servomotor, which is measured in a numerical control apparatus of an existing numerical control machine tool, is observed, and a backlash is detected by calculating a transfer distance of an output shaft of the servomotor at a torque peak, without adding additional positioning detection equipment, thereby detecting an accurate backlash amount without adding additional equipment.

A C-type CNC machine center generally includes a chassis, a displaceable table, a work table, a working spindle, a coupling seat, and a driver device. The chassis has a working area, a power area, and a displacement channel communicating with the working area and the power area. The displaceable table is slidably mounted to the chassis and located in the working area. The coupling seat is slidably coupled to the base seat in the power area and includes an elongate hollow body and is fixedly mounted, with an end thereof, to the displaceable table. The driver device includes a motor mounted to the base seat in the power area and a ball screw coupled to the motor and the coupling seat to drive the coupling seat and the displaceable table to synchronously conduct reciprocal movement in a given direction. The coupling seat separates the ball screw from the working area.
