PURPOSE: A punching apparatus is provided to alternately punch an object with two core punches using two slide cams, thereby improving punching speed and productivity. CONSTITUTION: A punching processing apparatus(100) comprises upper and lower slide cams(110,130) and first and second core punches(120,140). The upper slide cam reciprocates in a horizontal direction. A first punching unit(121) for punching a first object(1) is formed on the bottom of the first core punch. The first core punch reciprocates in a vertical direction by interlocking with the upper slide cam. The lower slide cam reciprocates in a horizontal direction. A second punching unit(141) for punching a second object is formed on the top of the second core punch. The second core punch reciprocates in a vertical direction by interlocking with the lower slide cam.
