摘　　要：为解决CTM-30车丝机加工API大管径、高钢级、偏梯扣螺纹类型的钢管时螺纹锥度不规则变化的问题,对车丝刀盘的同圆度检测分析。发现了锥度不规则变化问题的根本原因。通过改进生产工艺、降低切削载荷来提高同圆度精度,保证管端螺纹锥度的精度稳定性,提高产品合格率。In order to solve the problem of the thread taper irregular change when machining large-diameter, high- grade steel, Trapezoidal API thread pipes with CTM - 30 threaded machine tools, Find the root cause of the problem of the thread taper irregular with the Detection and analysis of the Concentricity of Turret to improve the accuracy of Concentricity with Changing the production process and Reducing cutting forces, Ensure the Stability of the accuracy of thread taper, In- crease the rate of qualified products.
