Bur eliminating machine for the processed stainless steel plate

The present invention relates to an apparatus to deburr a corner of a surface-processed stainless steel plate, and more specifically, relates to a deburring apparatus to be operated by corresponding to bending with respect to a linear deburring apparatus by bending of the place generated during cutting of the stainless steel plate difficult to be fixated by a magnetic force. According to the present invention, the apparatus comprises: a plate fixation unit (100) to press and fixate the surface-processed stainless steel plate; a deburring unit (200) to cut burr generated in the stainless steel plate fixated in the plate fixation unit; and a processing position adjustment unit (300) to adjust a processing position for the stainless steel plate of the deburring unit. Thus, the burr generated after surface processing is able to be automatically removed. In particular, the burr of the plate bent during the processing is able to be removed while a cutter is automatically operated in accordance with the degree of bending, and thereby productivity is increased and at the same time, an accident generated when a worker performs deburring is able to be prevented.

Throw-away type end mill

엔드밀본체(1)의 선단외주부에 제1, 제2의 팁(4A,4B)이 엔드밀본체(1) 둘레방향으로 어긋나서 또, 엔드밀본체(1)의 축선(0)주위에 있어서의 절삭날(6,6)의 회전궤적이 서로 오우버랩하며, 또한 제1의 팁(4A)의 절삭날(6)이 제2의 팁(4B)의 절삭날(6)보다도 약간 선단측으로 돌출하도록 배치되어 있다. 더욱이, 이 제2의 팁(4B)의 기단측에는 제3의 팁(4C…)이 그 절삭날(6)의 회전궤적을 제2의 팁(4B)의 절삭날(6)의 후단으로 연속시켜서 기단측으로 향함에 따라서 엔드밀회전방향 후방측으로 향해서 나선을 그리도록 배치되어 있다. 각 팁(4…)은, 같은모양, 같은크기의 1종류의 팁으로 되어 있다. The first and second tips 4A, 4B are displaced in the circumferential direction of the end mill body 1 at the tip outer peripheral part of the end mill body 1, and around the axis 0 of the end mill body 1 Rotational trajectories of the cutting edges 6 and 6 of each other overlap each other, and the cutting edge 6 of the first tip 4A protrudes slightly to the tip side of the cutting edge 6 of the second tip 4B. It is arranged to. Furthermore, at the proximal end of the second tip 4B, the third tip 4C ... continues the rotational trajectory of the cutting edge 6 to the rear end of the cutting edge 6 of the second tip 4B. It is arrange | positioned so that a spiral may be drawn toward the end mill rotation direction back side as it goes to a base end side. Each tip 4... Is a tip of the same shape and the same size. 팁 관리를 대폭으로 간소화하고, 또 특히 제1의 팁(4A)의 소모를 억제하여 팁전체의 소모정도의 균일화를 도모할 수 있다. The tip management can be greatly simplified, and in particular, the consumption of the first tip 4A can be suppressed, so that the degree of consumption of the entire tip can be equalized.
