Low frequency vibration machining center for breaking up chip

A low-frequency vibration machining center, comprising:

• a cam;
• a transmission shaft, wherein an end of the transmission shaft is connected to the cam, and another end of the transmission shaft is adapted to be connected to a driving device;
• the cam and the transmission shaft are coaxial;
• the driving device is adapted to drive the transmission shaft to rotate about a first axial direction and simultaneously drive the cam to rotate;
• a roller disposed at a position where the roller touches a cam surface of the cam;
• a tool holder adapted to be connected to a tool;
• a driven follower defined to have a second axial direction that is perpendicular to the first axial direction;
• the roller and the tool holder are respectively disposed at two opposite sides of the driven follower along the second axial direction;
• an elastic member providing an elastic force to allow the roller to keep in contact with the cam surface of the cam;
• wherein when the cam is rotated, the cam pushes the roller to drive the driven follower and the tool holder, which is connected to the driven follower to move back and forth in the second axial direction.
