銑刀長度選用以及疊板厚度計算方法
Method of calculation for required flute length base on PCB stack height:
刃長選用=排屑空間+上蓋板厚度+疊板厚度+鑽透深度
Required Flute Length = Clearance for material removal + Surface board thickness
+ Stack height + Depth of tool in base board
各種銑刀之用途及其特性(Our
Products):
(一) JRR型銑刀(JRR series):
特性(Features):
適用於PCB外週及開槽加工刀具，有鑽石目形狀的切刃，重視切屑的排出性，加工板面光滑是以延長刀具壽命為目的而設計的。
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.
(二) JR型銑刀(JR series):
特性(Features):
右旋刀刃螺紋狀銑刀，針對板邊要求高精密細度而設計，適用於PCB金手指端面加工及精度高之板材修邊加工。
Milling cutter with a right-turn blade edge is designed for board sides requiring
high precision. It is suitable for PCB golden-finger surface processing and
precision board edge trimming.
(三) JCB型銑刀(JCB series):
特性(Features):
