In the article, it is found that the decrease of pressure of chuck can effectively improve the stability of single value for thread by checking mechanical reasons and workpiece programme starting with solving the product quality problem causing unstable main single value for thread in production. The normal pressure of main chuck is 4 MPa, it is reduced to 2 MPa by using cooperatively commands M05 and M25 of workpiece programme. Practices proved that the unstable change for stand off and taper of coupling thread could be effectively avoided and waste products with ultra-poor single value could be reduced by reducing the pressure of chuck for coupling thread to contribute to cost reduction.
