近年来,可转位面铣刀上采用了带修光刃的刀片,图中所示的精密镗刀,其可转位刀片上磨有一圆弧形正前角断屑台,从而形成椭圆形的刀刃,可起修光作用。用该种刀具加工时,其进给速度是带圆弧刀尖ISO 可转位刀片的5至10倍。这种镗刀的刀片材料可在耐用度高的情况下,采用较高的切削速度.更块精镗刀夹后,ISO 刀片也可用于精切。用菱形导轨上的滑块粗调.用精镗刀夹精调镗孔直径.这种镗刀标准的镗孔直径范围在60至305毫米。对于带75—150毫米接长杆的和双刃镗刀,以及镗孔直径60—75毫米(下限范围)和255—
In recent years, the indexable face milling cutter blade with a wiper edge, the figure shown in the precision boring tool, the indexable blade on the mill has a circular arc front rake chipbreaker, so as to form an oval The blade, can play light effect. With this type of tooling, the feed rate is 5 to 10 times that of an ISO indexable insert with a round nose tip. This kind of boring knife blade material can be used in higher durability case, the higher cutting speed.More precise boring tool holder, ISO blade can also be used for precision cutting. Rough adjustment of the slider on the diamond guide, fine bore diameter adjustment with a fine boring tool with a standard boring bore diameter of 60 to 305 mm. For double and double-edge boring tools with 75-150 mm long bar and boring holes 60-75 mm (lower range) and 255-
