Ball raise the level of technology and manufacturing quality is the key to speed the production process of the key processes to achieve CNC technology, including CNC turning centers, CNC screw grinders, CNC internal thread grinding centers, CNC IF quenching equipment. CNC grinding machine screw lead not only get a high precision, SFT indexing precision ball screw threaded stud, also automatically compensate for wheel wear lead to changes in the diameter size of DFM screw ball screw, which is precisely the high-speed transmission require the entire travel tightening torque and stiffness needed stability. Internal threads on the CNC grinding center the ball nut once the installation is complete threaded raceway surface grinding and assembly base, which will greatly enhance the precision ball screw is installed on the host, so that the high-speed transmission more smoothly. Correction using CNC grinding wheel or diamond wheel to large helix angle of the double arc profiles correction obtained precision raceway truncate, the balls and fitness fr raceway in the best condition to improve contact stiffness, improve ball rolling in the fast fluency. If we threaded raceway polishing or lapping and polishing BSH super ball screw raceway surface roughness up foot Ra0.04 ~ 0.08μm, fit ball and raceway can be increased by about 20%, can greatly reduce the high-speed operation noise, increased fatigue strength. To ensure the safety and reliability of high-speed operation, the process from cold start to strictly control the inherent quality, first to strictly control the quality of raw materials, ball screw, and secondly to the implementation of "small deformation without cracks" in the whole process of cold processing processes. IF quenching process using CNC meet the requirements of both hardness and case depth, and can reduce the quenching process of bending and axial deformation, so that the total length of the screw uniform hardness. Implementation of the ball nut light (vacuum) can not only reduce the deformation hardening, avoid quench cracking tendencies, but also to improve the quality of the hardened layer, improve fatigue life. For hollow ball screws, using BTA deep hole drilling within the BAT and DF dual-fuel injection deep hole drilling system that can meet the high-speed ball screw hole on the straightness, the roughness and the outer coaxial requirements. Usually felt ring nut vice sealing, the thickness of the felt ring is 2 to 3 times the pitch, and the shape of the threaded bore formed so tightly encloses the screw, and a nut or a sleeve mounted at both ends of the groove hole. In addition to using a soft felt seals, but also can be used oil and rubber or nylon material. Because seals and screw direct contact, so the dust is better, but also increases the friction ball screw nut torque. To avoid this friction torque can be used by a hard plastic non-contact labyrinth seals, made the hole and screw thread rolling road opposite shape and leave some gaps.
