经过近年来不断的实践,我们在刃倾角为10°～25°的铰刀上,增设了内冷却装置,冷却液经刀杆内孔喷向铰刀上的六个孔,以冲擦铰刀头上的六条容屑槽,使刃倾角的优点更能发挥,更适合于深孔铰削,效果很好。刃倾角铰刀的主要优点是利用刃倾角排屑,把切屑推向待加工面。现冷却液再从后面喷出,这便更好地帮助把切屑推向待加工面。一般铰刀的主要问题是不易排屑,切屑拥塞在容屑槽上,较粗的切屑刮伤已加工的表面,较小的切屑则粘在刀刃与孔壁之间,
After continuous practice in recent years, we reamer 10 ° ~ 25 ° edge reed, the addition of an internal cooling device, coolant through the arbor within the hole to reamer six holes to reef reamer The head of the six chip flute, the advantages of edge tilt more play, more suitable for deep hole reaming, the effect is very good. Cutting edge angle reamer’s main advantage is the use of edge cutting chip, the chip to be machined surface. The coolant is now sprayed out of the back, which helps to better push the chips toward the surface to be machined. General reamer main problem is not easy to chip, chip congested in the chip flute, the rough chip scratched surface has been machined, the smaller the chip is stuck in the blade between the wall and the hole,
