許多難加工材料應用廣泛,其中難加工材料,如不銹鋼中Cr和Ni含量較高,Cr雖能提高不銹鋼的強度和韌性,但增加了不銹鋼與刀具的粘結傾向;Ni可起到穩定組織的作用,但組織塑性大,容易引起加工硬化,採用鎢鈷類硬質合金刀具進行加工,但加工效果並不十分理想。
碧威不銹鋼專用切削刀具是以最新金屬陶瓷材料製作而成,針對成分內含鎳18%以上的難切削材而開發,擁有更好的抗折強度及濕式切削,加工時有更優越的耐損性和穩定性,在加工不銹鋼切削壽命更是鎢鋼刀具5倍以上且在切削表面具有優異的表現。

Step drill, the related accuracy in manufacture process is the most important factor for cutting quality. If the precision isn’t controlled well, it will cause hole too rough and even caused reject of work piece. Not only geometry, specification, accuracy, and surface quality, but also the drill volume are important points for the cutting quality of step drill.
During drill process, if the chip groove isn’t well-produced, it would happen wall friction, extrusion, brushed and scratches on its surface. It will cause the bad quality of working surface and obstruction, drill bit stuck, and even broken the drill bit.
