Pull type to bore hole make an user OK in process of deep aperture treatment obtain remarkable linearity to machine the effect. The first focal point that should work is when the wall that should keep consistent is large (in the casting canal that growing for example) , this technology aux will be able to obtains similar result. In a lot of application, mix effectively efficient the capacity that the ground has deep aperture is made appears crucial, the trade is processed in the metal same also, deep aperture production technology is to be able to develop one of degree of highest technologies. It covered all sorts of different processes and method. Make the supplier of machine, tool and automation as a deep aperture, unisig (Menomonee Falls, wisconsin) say, the industry limits that it serves can include system of aerospace, car, national defence, hydraulic pressure, mould to make, oil field and the sources of energy. However, the working domain of the plant that deep aperture makes a technology be used technically at realizing this kind of ability, workshop, however, the technical supplier of such as Unisig thinks, the more extensive knowledge that creates to deep aperture will give new user with precious opportunity. How does production technology master as deep aperture a few most a case of extreme challenge, unisig mentioned a particularly interesting technology: Pull type to bore hole make an user OK in process of deep aperture treatment obtain remarkable linearity to machine the effect. The first focal point that should work is when the wall that should keep consistent is large (in the casting canal that growing for example) , this technology aux will be able to obtains similar result. Alluding like its name place in that way, pull type to bore hole the Kong Lai that includes to have through showing pulls broach to provide. Pull boring undertake operating on the same table machine that making primitive hole normally. Below this kind of circumstance, pass existing aperture, insert boring lever existing aperture with all sorts of means. Should appear in another end hind, the lever that it is boring deploys a Chan Ren to pull boring head. Catch boring lever to work in mechanism of cutting tool drive, carry work by hind pull. Boring lever rotates in a direction, and workpiece is in below the drive of working runner shaft rotate by opposite way. Be aimed at workpiece material, tool head has the hard alloy bit of proper order and degree and style. The function of this razor blade resembles an ID rotational tool, be pulled when it workpiece when, can enlarge aperture a little. The cooling pump all round boring lever cuts bits outwards up through its center, this conduces to purify redundant metal and protective surface. According to the application of Unisig engineer Sarang Garud introduces, if material, mould and craft condition are pretty good, the common difference of deviate of electric acupuncture point that realizes through playing boring place is less than 0. 08mm/m workpiece length. However, want to reach level of this one linearity, need the operation that pull boring possibly a few times. Be aimed at homocentric degree, use much blade to pull boring head to replace odd blade tool. Tool of a blade has 2 to come normally 6 razor blade, mr Garud says. Wear-resisting fills up the forehead that is located in bit, so that be in cut process, make show poriferous ID to be able to win provides support. Under photograph comparing, odd blade head is by the support of ID of finished product aperture, accordingly, wear-resisting mat is located in at the back of bit. Mr Garud points out, pull boring to involve a few subtle part. For example, habitual practice is the hole that through be in when making primitive hole the component gets an in part, rotate its end points comes another end, two what catch bore. This kind of practice can reduce the state of the integral linearity of final aperture, because be connected alone with by,come over whole get a Kong Xiangbi, deviate is less. Accordingly, in pulling type to bore hole to move straight operation in its can " forestall one's opponent by a show of strength " . It is OK to pull type to bore hole be applied at any components with OK and compatible machine of a deep aperture. The only limit on component length is the length of deep aperture machine. Pull boring to be able to add man-hour to assure to have same precision and stiffness in deep aperture. In addition, unisig machine is OK automatically the rate of inductive refrigerant and pressure, make the user can pass state of close in the process that pull boring surveillant cut to protect workpiece and cut cutting tool thereby. The progress of deep aperture technology will enhance the ability of professional workshop, enlarge its to machine medium use in general metal at the same time. Through offerring whole treatment system, cutting tool, cooling fluid, fittings and engineering technology, unisig makes clear, it already prepared supportive client any demand. CNC Milling
