Minimal deflection in long machining passes Advantages : Good surface roughness 2.Chips are broken into small pieces, though Disadvantages :If a machining pass is long, the guide bush can not the workpiece material is sticky support the workpiece. Disadvantages:The pre-stage machining may cause fractures, because of interrupted machining.
