Cold pull burnish the makings application in ball guide screw

Change the rapid development of equipment as domestic and international numerical control, the application of guide screw of corresponding functional component ball is wider and wider also, demand is swift and violent increase. Below the premise that assures quality, to shorten the delivery of ball guide screw is periodic, reduce manufacturing cost, personnel of my company technology experiments through fumbling for years, to conventional technology challenge, try out is cold pull burnish makings replace old ball to change anneal wool preform to machine ball guide screw, via turning over a second-round exam to make for many times, now already batch throws production. 1.

Craft compares the comparison of new old technology to see watch 1. Express 1 conventional technology to move qualitative ->- of half fine vehicle>Divide stress ->Fine vehicle ->- is ground outside>Milling machine ->Intermediate frequency quenchs cold pull burnish - of vehicle of makings technology energy>Milling machine ->Intermediate frequency quenchs 2.

Function and price are compared (1) function is analysed from foreign data, product and in light of the product that home travels together, guide screw core all changes anneal condition or normalizing condition for the ball, core hardness is 12HRC of 9 ～ , change anneal to burnish the core organization of makings, hardness agrees with Leng Laqiu, accord with the demand of trade of ball guide screw about standard of conditioning treatment of material of ball guide screw, can satisfy the use requirement of the user. The conditioning treatment of ball guide screw and nut preform, can pledge according to different capable person and ask to undertake the ball changes anneal, mix the craft such as qualitative, normalizing, carry out by JB/ GQ1063 standard. Through trial-produce we discover, when core hardness is 12HRC of 9 ～ , guide screw is in quench after reaching, in grinding easy turn. Through negotiating with steelworks, raise core hardness 18 HRC above, together with change quenchs means is reached heat the adjustment of parameter, make guide screw function gets assuring, these problems get basically already settlement. (2) price can see from technological process, use Leng Laqiu to change anneal to burnish expect and cold pull tone to pledge hardness burnishs makings hind is OK leave out moves the vehicle of qualitative, half fine, circle outside dividing stress, raceway thick outside grind 4 working procedure. With me the factory produces guide screw of a S101-01-301 to be exemple, if watch 2, watch shows 3 times,the price compares: 3.

Actor defect advantage: ① can improve manufacturing efficiency, shorten manufacturing cycle makes an appointment with 8 ～ 10 days. ② reduces manufacturing cost substantially. ③ technological process from the tradition big and stride to careful treatment completely. Defect: The supplier of ① home satisfaction is less. ② home steelworks is more than the ball of 60 Mm above to change anneal to organize unwarrantable quality. ③ changes anneal to burnish as a result of the ball the hardness of makings is inferior, pledge with tone voice photograph is compared, the integrated and mechanical function such as its torque, intensity, stiffness is inferior, restricted its to compare the application that waits for a domain in accurate machine tool, old long way. Pass we and steelworks for many times experiment, research, move qualitative hardness to burnish now makings already reached a plant, to burnish the application of makings extended a space. 4.

Epilogue can see from above analysis, cold in industry of ball guide screw pull burnish although the application of makings returns existence a lot of problems, but improve material position through ceaseless effort, adjust hot-working craft, its application will bring bigger development perspective for the development of ball guide screw!
