(KO) 초경질 소재 가공용 스파이럴 탭
Abstract: front page image
(EN)The present invention relates to a spiral tap for processing an ultra-hard material, wherein an inclined initial processing part is formed at the front end and sequentially processes an ultra-hard material, thereby smoothly preventing damage to a cutting blade due to a chip. The tap comprises: a tap body provided in a long rod shape and having a circular cross section at the rear end; an initial processing part provided with one pair of upper and lower inclination blades processed to be sharp and inclined toward the front end of the tap body; a plurality of spiral grooves provided immediately before a coupling part in the initial processing part, formed in a spiral shape along the outer circumferential surface of the tap body, and having an inside portion rounded in a semicircle shape; and a plurality of cutting blades provided at the rear end of the initial processing part and formed in a thread shape along the portion at which the spiral grooves are formed.
(FR)La présente invention concerne un taraud à entrée hélicoïdale pour le traitement d'un matériau ultra-dur, une partie inclinée de traitement initial étant formée au niveau de l'extrémité avant et traitant séquentiellement un matériau ultra-dur, évitant ainsi en douceur une détérioration d'une lame de coupe due à un copeau. Le taraud comprend : un corps de taraud prévu en forme de tige longue et de section transversale circulaire au niveau de l'extrémité arrière ; une partie de traitement initial pourvue d'une paire de lames d'inclinaison supérieure et inférieure traitées pour être tranchantes et inclinées en direction de l'extrémité avant du corps de taraud ; une pluralité de rainures hélicoïdales placées immédiatement avant une partie d'accouplement dans la partie de traitement initial, en forme de spirale le long de la surface circonférentielle externe du corps de taraud, et comportant une partie interne arrondie en une forme semi-circulaire ; et une pluralité de lames de coupe placées au niveau de l'extrémité arrière de la partie de traitement initial et en forme de filetage le long de la partie au niveau de laquelle sont formées les rainures hélicoïdales.
(KO)본 발명은 선단에 경사진 초기 가공부를 형성하여 초경질의 소재를 순차적으로 가공하여 칩에 의한 절삭날의 파손이 원활히 방지되도록 하는 초경질 소재 가공용 스파이럴 탭에 관한 것으로, 본 탭은 원형 단면의 긴 봉 형태로 구비되고, 후단에 결합부를 가지는 탭몸체와; 상기 탭몸체의 선단에 전방을 향해 경사지면서 뾰쪽하게 가공되어 형성되는 경사날이 상하 한 쌍으로 형성되는 초기 가공부와; 상기 초기 가공부에서 상기 결합부의 직전 까지 형성되고, 상기 탭몸체의 외주면을 따라 나선형으로 형성되며, 내측이 반원형 형태로 라운드지게 형성되는 다수의 나선홈과; 상기 초기 가공부의 후단에서 상기 나선홈이 형성된 부위를 따라 나사산 형태로 형성되는 다수의 절삭날을; 포함한다.
