Ball screw is an ideal product to convert rotary motion into linear motion or linear motion into rotary motion. It consists of a screw, a nut, and a ball. Its function is to convert the rotary motion into linear motion, so that the spherical screw can be further expanded and developed. The importance of this development is to convert the bearing from rolling motion to sliding motion. Because of its low friction and high rigidity, it is widely used in various industrial equipment and precision instruments. Choose high-quality ball screws to look for titanium, professional quality assurance, because professional, so excellent!
Ball screw is commonly divided into cold rolling screw and grinding screw. In addition, left screw screw can be customized! That is to say, ball screw is so important in mechanical equipment, how should we process it?
How to process balls? The following is my personal experience to explain the processing technology of cold rolled ball screws:
(1) Blanking (usually the lead screw is 3 meters or 6 meters in length, cut according to the actual needs of customers)
(2) Straightening (professional straightening machine straightens the lead screw to achieve the straightness of the lead screw and avoid the lead screw from jumping after the wire loading machine)
(3), spheroidizing heat treatment (use the high frequency quenching machine for the end dequenching heat treatment operation of the screw shaft)
(4) Rough turning of the outer circle (generally purchasing a lathe for machining the outer circle of the shaft end of the screw rod)
(5) Fine turning (fine turning of threads, keyways, spring grooves, etc.)
(6) Alignment (alignment before installation)
(7) Quality control operations (check the drawings and processing dimensions)
(8), nut assembly (use the sleeve method to assemble the nut)
(9) Debugging preload (professional assemblers conduct preload testing)
(10), inject lubricating oil/grease into the nut and screw.
(11) Packing and shipping (screw nuts are first packed in plastic PE bags, then packed in cartons, and filled with pearl cotton in the middle)
