Foreign body into the ball track (1) Packaging Materials impede ball tracks: the time of delivery in many materials and corrosion protection bag to wrap the ball screw, if performed at the time of packing or arranged Failing to proper procedures, foreign objects or other objects It may hinder ball track, rather than the normal result of sliding the ball rolling even stuck. (2) processing debris orbit: If no ball screw ball screw installation squeegee, machining chips or dust accumulation will impede ball track, resulting in poor smoothness, reduced accuracy and reduced service life. 3. Over stroke over stroke can cause reflux tube damage and dents Wycombe ball screw, and even rupture, causing the ball can not function properly; in this harsh operating conditions may result in the release of the screw or nut bead groove surface. Cause over travel may occur in the machine setting, the limit switch failure or crash, to prevent further damage caused by ball screw, ball screw before reinstalling the manufacturer is subject to re-inspection. Ball raise the level of technology and manufacturing quality are key to the speed of the production process of the key processes to achieve CNC technology, including CNC turning centers, CNC screw grinding machine, CNC internal thread grinding centers, CNC IF quenching equipment. CNC grinding machine screw lead not only get a high precision, double threaded indexing precision ball screw Yanzhou, also automatically compensate for wheel wear leads to changes in the size of the screw in diameter, and this is precisely the requirements of the whole high-speed transmission tightening torque and stiffness stable for travel needs. On CNC grinding center the ball threaded nut threaded once installation is complete grinding roller and assembly base in turn made ball screw, which will greatly enhance precision ball screw is installed on the host, so that the high-speed transmission is more stable. Using CNC grinding wheel or diamond wheel to large helix angle of the double arc profiles corrected, can be obtained with high precision raceway truncate, the balls and fitness fr raceway in the best condition to improve the contact stiffness, improve ball rolling in the fast fluency. If we threaded raceway polishing or Superfinishing throw, raceway surface roughness up foot Ra0.04 ~ 0.08μm, goodness of fit ball and raceway can be increased to 20%, can greatly reduce the noise running at high speed, increased fatigue strength. To ensure the safety and reliability of high-speed operation, the process from cold start to strictly control the inherent quality, to strictly control the quality of the material first, and secondly to implement the "little distortion crack" technology in the whole process of cold processing. IF quenching process using CNC can achieve the requirements of hardness and case depth, but also to reduce the quenching process of bending and axial deformation, so that the total length of the screw uniform hardness. On the ball nut for bright (vacuum) will 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, use within BAT BTA deep hole drilling and deep hole drilling DF dual fuel injection system that can meet the high-speed ball screw for deep hole straightness, the roughness and the outer coaxial degree requirements.
