* Standard edge geometries are not suitable for reaming titanium and high temperature alloys. Legend:
In order to choose a proper geometry, ask for our recommendations.
• The given cutting data recommendations refer to the short holders (3xD effective reaming overhang). Grade LB IC908 Cutting geometry
For longer holders, the cutting speed should be reduced proportionally. Cutting Speed [SFM) Vc = 30 - 60
• For relatively large leading angles (spot-facing geometries), the feed should be reduced up to 30%.
• All the given cutting data recommendations refer to the machines with spindle through coolant supply. BAYO T-REAM head size fz = .002 - .006 BN4-BN6 Feed [IPT]
