Abstract: The heat sink processing method including the steps of: a working machine with a feeding mechanism is provided in a working zone; a power arm of the working machine drives an elastically extending and contracting knife set as well as a stopping and pushing mechanism comprising a fin fixing rod and a pushing edge; a material block is fixed on the feeding mechanism which progresses for a predetermined distance; the material block is cut after an equal moving distance each time and in a bevel way by the elastically extending and contracting knife set; at the time of bevel cutting and progressing, the stopping and pushing mechanism pushes and erects a fin cut last time; the process is performed till cutting of the material block is completed.

Abstract: A heat sink apparatus includes a working machine having a power arm for driving a knife set forwards and backwards and has a follower axle with a cam having a sensor for sensing the rotation of the cam; a material feeding mechanism on the top surface thereof includes a clamping seat engaging a bolt in the material feeding mechanism. One end of the bolt connects to a motor. A microcomputer control device having an input end connected to the sensor receives a signal emitted from the sensor while the output end is connected with the controlling of the motor of the material feeding mechanism.
