GMM2420-020MW (Grooving) 1. Solid end mill Roughing E When using TKFB12R28010M (for back turning / right hand) When using TKFB12R28010M (for back turning / right hand) Finishing (Countermeasures 1) Use right-hand toolholder Advantages: Advantages: 1. Minimal deflection in long machining passes • Good surface roughness 2. Chips are broken into small pieces, though the workpiece material is sticky Disadvantages: Disadvantages: • If a machining pass is long, the guide bush can not support the workpiece. • The pre-stage machining may cause fractures, because of interrupted machining When using TKFB12L28010M (for back turning / left hand) When using TKFB12L28010M (for back turning / left hand) Finishing (Countermeasures 2) Use left-hand toolholder Advantages: Advantages: 1.
