Thread machining method: Turning whorl

Turning whorl can use figuration lathe tool or whorl combs knife. When whorl of the screw cutting outside the car, workpiece every turn, the transmission catenary of the machine tool makes sure axial of workpiece of lathe tool edge is accurate and even ground is mobile a lead. The whorl inside the car can use figuration lathe tool in whorl of the turning on lathe or whorl combs knife. With whorl of turning of figuration lathe tool, because cutting tool structure is simple, it is odd a commonly used method with workpiece of pre production whorl; Comb with whorl knife turning whorl, manufacturing efficiency is tall, but cutting tool structure is complex, only comfortable the short whorl workpiece at fine tooth of the turning in production of medium, big batch. The pitch precision of whorl of echelon of common lathe turning can achieve 8 ～ only commonly 9 class (JB2886-81, similarly hereinafter) ; Whorl is machined on the thread cutting lathe of specialization, productivity or precision can rise significantly.
