Chip control improvement in back turning Chip control improvement by tool pass changes I Roughing with grooving tools (1) GMM2420-020MW (Grooving) Roughing Ar Finishing (Countermeasures 1) Use Right-hand toolholder (1) When using TKFB12R28010M (for back turning/right hand) Advantages Good surface roughness Disadvantages If a machining pass is long, the guide bush can not support the workpiece. (2) When using TKFB12L28010M (for back turning / left hand) Finishing (Countermeasures 2) Use Left-hand toolholder Advantages 1. Good surface roughness 2. High precision cutting if the machined portion does not contact the guide bush Disadvantages If a machining pass is long, the guide bush can not support the workpiece. Chip control improvement by tool pass changes II Pre-Stage machining is processed with solid end mill (1) 2FESW040-040-04 (Solid End Mill) (1) When using TKFB12R28010M (for back turning/right hand) Advantages 1. Minimal deflection in long machining passes 2. Chips are broken into small pieces, though the workpiece material is sticky. Disadvantages The pre-stage machining may cause fractures, because of interrupted cutting. (2) When using TKFB12L28010M (for back turning / left hand) si = 3 Advantages 1. Minimal deflection in long machining passes 2. Chips are broken into small pieces, though the workpiece material is sticky. 3. High precision cutting if the machined portion does not contact the guide bush Disadvantages The pre-stage machining may cause fractures, because of interrupted cutting.
