本文针对我国目前机械加工“以铣代磨的新要求,设计制造了铣削铸铁件平面的高效密齿精铣刀。该刀结构简单、制造容易、效率高、成本低。是适合我国国情的理想刀具。一、铣刀结构如图1所示,该刀由刀体、刀垫、刀片、定位环、定位螺栓和夹紧机构所组成。其特征是:在定位环的外表面上有多个贯通定位环两端面的凹槽,刀片的一个主切削刃置于定位环的凹槽中,刀片的后刀面与凹槽 In this paper, the current machining in our country "to the new requirements of milling instead of grinding, design and manufacture of milling the surface of the iron-casting precision tooth cutter fine. The knife structure is simple, easy to manufacture, high efficiency and low cost. Is ideal for our national conditions A cutter structure shown in Figure 1, the knife by the blade body, pad, blade, positioning ring, positioning bolts and clamping mechanism is characterized by: the outer surface of the positioning ring has a plurality of Through the groove of the two end faces of the positioning ring, one main cutting edge of the blade is placed in the groove of the positioning ring, the flank of the blade and the groove
