铣刀长度选用以及叠板厚度计算方法
Method of calculation for required flute length base on PCB stack height:
刃长选用=排屑空间+上盖板厚度+叠板厚度+钻透深度
Required Flute Length = Clearance for material removal + Surface board thickness
+ Stack height + Depth of tool in base board
各种铣刀之用途及其特性(Our
Products):
(一) JRR型铣刀(JRR series):
特性(Features):
适用于PCB外周及开槽加工刀具，有钻石目形状的切刃，重视切屑的排出性，加工板面光滑是以延长刀具寿命为目的而设计的。
Suitable for tooling up the edge of PCB and groove cutter. In addition to
diamond eye cutting shape， it functions well to release cutting waste. Smooth
processing board face is designed to lengthen the cutter life.
