螺旋絲攻系列
螺旋絲攻對在盲孔內攻牙，切屑連續排出的鋼鐵材質(zhì)效果良好。因為約35°之右旋蝸槽切屑可從孔內向外排出，切削速度可較直槽絲攻加快30-50％，盲孔
之高速攻牙效果良好因排屑順利。對鑄鐵等切屑成粉末狀的材料效果差。
一般用螺旋絲攻
漲大徑用螺旋絲攻
不銹鋼用螺旋絲攻
深孔用螺旋絲攻
鍍鈦處理螺旋絲攻
氧化處理螺旋絲攻
鋁專(zhuān)用螺旋絲攻
Screw tap series
Screw tap in the blind hole tapping, chip continuous discharge of steel material effect is good. Because about 35 °
of the right hand worm groove chip from the hole introverted effluent out, cutting speed can be a straight
flute silk attack speed up 30-50%, blind hole of high speed tapping effect is good for clearance smoothly.
For cast iron, and other chip into powder material effect is poor.
General use screw tap
A major diameter screw tap
Stainless steel screw tap
Deep hole with screw tap
Plating titanium processing screw tap
Oxidation treatment screw tap
Aluminum special screw tap
