SMC Long Type Solid Carbide End Mill with Four Cutting Edges (Uneven Indexing)---Basic Type
Features:
1、All dimension is fixed by our norm and also accept non standard order.
2、Tolerance of dc +0.02/0
3、Tolerance of shank h6
4、Having end cutting edge with tip angle
5、Dimension of chamfer on the corner C value:
D≤Φ3，C=0.05～0.1；Φ3＜D≤Φ8， C=0.1；
Φ8＜D≤Φ12， C=0.15；Φ12＜D≤Φ16， C=0.2；
D＞Φ16，C=0.3
6、Helix angle 36°- 37°
7、Achieving high surface quality especially for slot and side machining case.
SMC Endmills
Surface Milling Cutter-Unequal Indexing Flutes, Variable Leads
Features:
□ Uneven indexing, variable lead restraining the vibration and chatter.
□ Design different uneven value according to different material and case.
□ Having no fixed machining frequency avoiding vibration and reducing chatter.
□ High surface quality.
