Guide screw of unit of numerical control system, main shaft, ball deputy with scroll slideway deputy wait for key of machine tool of homebred numerical control the production of the component is opposite for lead plane, development lag, breed degree of little, industrialization level of low, technology is not high, with abroad photograph comparing is put in very big difference, especially the development demand of market of machine tool of high-grade numerical control, some products must count an import. So what is we understand ball guide screw today after all, how do we want ability to capture this difficulty? Lever of silk of ball of ball guide screw is to will answer have a change of luck to move translate into to move point-blank, or the good product that moves circumgyrate of sharp movement translate into. Ball guide screw by ball of screw, nut, steel, beforehand sheeting, reverser, dustproof implement composition. Its function is change whirligig into sharp movement, this is Ike Mu screw is farther outspread with development, the principal port of this development turns bearing into scroll the movement from slip movement namely. Because have very little attrition resistance, ball guide screw is applied extensively at all sorts of industry equipment and accurate instrument. Ball guide screw is tool machine and accurate machinery go up most the transmission cell that often uses, its are main the function is move whirligig changeover into linear, or relapse torque changeover into axial active force, hold a high accuracy, reversibility and efficient characteristic concurrently at the same time. Ball guide screw develops up to now, the fixed position precision that uses each industry machine already extensively is like accurate machine tool on control (Precision Machine Tools) , industry is mechanical (Industrial Machinery) , electron is mechanical (Electronic Machinery) , conveyer fetterses (the important leading role of Transport Machinery) . Utility freeboard DN is worth ball guide screw: Machine of high speed tool, end of machine of integrated machining center builds high speed type ball guide screw: Carry a system quickly, general industry is mechanical, automation machinery high speed turns ball guide screw: Machinery of CNC machinery, accurate tool machine, industry, electron machinery, high speed changes mechanical nicety guide screw of abrade class ball: CNC machinery, accurate tool machine, industrial machinery, the electron is mechanical, conveyer fetterses, spaceflight industry, the screw cap such as device of switch of the brake that other antenna uses, valve rotates type (R1) series ball guide screw: Semiconductor machinery, industry machines with machine of robot, carpentry, Lei She machine, move send the rolling class ball such as device guide screw: The advantage with low attrition, smooth movement, offer money at the same time rapid and the price is low guide screw of heavy load ball: Full report type shoots a forming machine, punch, semiconductor to make machinery of brake of carry on one's shoulder of device, heavy burden, industry, forging press the circular means with instrument commonly used type has two kinds: Outer circulation and inside circulate. Ball calls outer circulation in what the contact breaks away from with guide screw sometimes in circular process; Call with what guide screw maintains a contact from beginning to end inside circularly. 1) outer circulation: Outer circulation is ball the helix chamfer that adopts nut appearance range after circular process ends or spile return guide screw the loop is entered afresh between nut. Nut of guide screw of outer circulation ball deputy when circulating by ball return means to basically have the type that carry a lid, intubate type and helix chamfer type. End of means of commonly used outer circulation covers type; Intubate type; Helix chamfer type. End covers type, one fore-and-aft aperture is machined on nut, regard the return trip of ball as the passageway, nut opens the return trip mouth that has ball on the cover board of two end, ball enters return trip canal from this, form a loop. Intubate type, it serves as with bent housing return conduit, sex of craft of this kind of structure is good, but outside highlighting nut style as a result of conduit, radial size is larger. Helix chamfer type, it is on the circle outside nut mill gives helix slot, two end of groove get a via and as tangent as whorl raceway, form return a passageway, size of radial of construction of type of spile of this kind of structure comparing is small, but make more complex. Structure of outer circulation of guide screw of outer circulation ball and workmanship are simple, use extensive. Its defect is raceway juncture part is done very hard smoothly, affect the smooth stability of ball raceway. 2) inside circulate: The loop all uses reverser to realize ball loop inside, reverser has two kinds of kinds. Reverser of columnar protruding key, its columnar part is built-in inside nut, upright ministry leaves have retrorse chamfer. Retrorse chamfer relies on face of the circle outside cylinder and the round key of the end on its to locate, in order to assure direction of alignment whorl raceway. Oblate set a reverser, reverser makes the same score key to set for general circle head piece, in the grooving that sets a built-in nut, its carry a ministry to leave have retrorse chamfer, with set piece outside outline fixed position. Two kinds of reverser are compared, latter dimension is lesser, the radial size that reduced nut thereby and shortened axial dimension. But of this kind of reverser outside the demand of grooving dimension precision on outline and nut is higher. Sort chooses the nut of ball guide screw, can divide according to the circular means of steel ball for: Bent housing type, circulator type, end covers type. The specialty of means of these 3 kinds of loops. Bent housing type (SBN, BNF, BNT, BNFN, BIF and BTK) these model, the search gets. Circular type guides a type (HBN) these model are the most typical nut, undertake circular through using bent housing to let steel ball. Steel ball is taken from the Ju in the groove of filar lever axis after entering bent housing, in returning groove again, do infinite loop exercise. Circulator type (DK, DKN, DIK, JPF and DIR) these model are most diminutive nut, change the advancing way of steel ball through circulator, cross external diameter of filar lever axis to return former, do infinite loop exercise. The type that carry a lid (SBK, SDA, SBKH, WHF, BLK, WGF, BLW, WTF, CNF and BLR) these model are the nut that the most appropriate high speed improves. Steel ball uses upright shell, be taken by Ju from inside the groove of filar lever axis in the via of nut, in returning groove again through via, do infinite loop exercise. Use a method correctly of ball guide screw (1) do not disassemble absolutely please ball silk lever. Otherwise, bring about dirt easily enter, make precision drops or cause trouble. (2) because be assembled afresh,make ball guide screw loses a function because of assembling a mistake easily, hope each user does not undertake assembly afresh so. If return the product our company, can be repaired with paid form and assemble its product afresh. (3) because of,axis of ball guide screw or nut are met sometimes self-prossessed and fall off, notice not to get hurt please. Throw the injury that injury or circular component may touch because of orbital when falling to bring about the forfeiture of product function carelessly. Need to be undertaken checking by our company at this moment, ask Wu to be sure to throw falling product to return our company so, be in charge of checking with paid form by our company. (4) when the phenomenon such as the occurrence bruise such as the external diameter that is like circular component, axis, orbit, injury, can cause a loop undesirable, bring about a product to lose a function thereby. Deputy usable lubricant comes to the protective ball guide screw of ball guide screw improve wearability and transmission efficiency. Lubricant cent is lube and grease two kinds big. Lube uses oil of turbine of engine oil, 90~180 date or oil of 140 main shaft. Grease can be used strange base grease. Grease is added inside whorl raceway and the housing space that install nut, and inside the space of nut of oily aperture infuse that lube passes housing to go up. Ball guide screw deputy the transmission component with other rolling friction, want to avoid abrasive particle and chemical and active material to enter only, can think these component are to be in what do not produce the job below tatty circumstance almost. But if boiling to fall into dirty content on the road, or use dirty lubricating oil, can hamper not only the normal movement of ball, and can make wear away to increase quickly. Industry of component of function of our country scroll is growing dimensions to go up, on management concept, more apparent difference exists with course of study of foreign person of the same trade on business management, this differentia is apart from serious already obstacle the development of equipment manufacturing industry, very adverse to revitalizing ethical industry. Accordingly: The technology that our country needs to develop mainly is the product that develops a high-powered, high quality scales quickly firstly, in order to satisfy the requirement of industrialization of machine tool of homebred and high-grade numerical control. It is level of rapid promotion production technology secondly, from innovatory craft proceed with, improve efficiency of the product quality that batch produces and production, shorten production cycle, a batch of competitive famous brand products are rolled out on this foundation. Around this two big questions, the key that realizes industrialization is to increase technical investment and capital investment. According to the development direction of high speed, nicety, compound, intelligence, environmental protection, the technology that need develops mainly includes: The field develops in the new product of scroll function component: - - deputy production technology mixes guide screw of ball of high speed of batch production nicety equip - - nicety of the high speed with form a complete set of linear electric machinery, tall stiffness, low noise rolls linear slideway pair - - the intelligence of need research and development according to lead plane changes, compound change, the high-powered scroll of Electromechanical unifinication: - - contented dimension stability, dependability, Yi Cheng sex and the new material that produce efficiency demand and hot project technology and the development that its equip - - what technology of cold rolling of nicety of ball guide screw reachs equipment is homebred change, scroll bearing is not is normally the brief stand-alone on the meaning fetterses one kind the ball guide screw under component P3 class popularizes cold rolling craft in the round - - introduce and digest absorb technology of " of hard milling of tornado of " CNC nicety, equipment is homebred change make whorl grinding is replaced with part of tornado mill method under P3 class - - ball is retrorse of device optimize a design to be reached shape the industrialization of production technology - - the relevant technology that improves raceway profile precision CNC Milling CNC Machining
