BACK TURNING TOOLHOLDERS TKFB INSERT Chip Control Improvement During Back Turning Chip control improvement by tool pass changes (D Chip control improvement by tool pass changes Roughing 1 GMM2420-020MW (Grooving) Pre-stage Machining is Processed with Solid End I (1) 2FESW040-040-04 (Solid End Mill) Roughing / Pre-Stage Machining Finishing (Countermeasure 1) Use Right-Hand Toolholder (1) When Using TKFB12R28010M (Back Turning / Righ-hand) (1) When Using TKFB12R2801OM (Back Turning / Righ-hand) Advantages Smooth Surface Finish Disadvantages If machining pass is long, the guide bushing can not support the workiece Advantages 1. Minimal deflection during long machining passes 2. Chips are broken into small pieces, though the workpiece material is elastic. Disadvantages The pre-stage machining may cause fractures, because of interruption (2) When Using TKFB12L28010M (Back Turning / Left-hand) (2) When Using TKFB12L28010M (Back Turning / Left-hand) Finishing (Countermeasure 2) Use Left-Hand Toolholder Advantages 1. Smooth Surface Finish 2.
