Manufacturer posts the hope success at main shaft

Over the base of model of classical main shaft that acting main shaft builds the II that Bryant company redesigns to succeed in this company. If do not have invalidation, why does that need to repair? This is the manner that Bryant Grinder company treats main shaft of design grinder wheelhead. This company holds this kind of viewpoint to be engaged in production all the time since 1936. But, in the past 10 come to 20 years the development of the change of product data and abrade technology, to machining equipment to reach its subsystem raised more requirements, also brought more opportunities. Bryant company has discovered the design of existing wheelhead main shaft brought production difficult problem. The design requirement of main shaft must be in appropriative machines main shaft on special machine tool, appear extremely likely otherwise very big tolerancepublic errand overlay. Overlay of this kind of public errand can be overcome, but at present however the market cannot bear its cost. Of the problem depend on current design common difference on the other hand indemonstrable scroll component (the compound precision that is used at forming wheelhead oneself and stiffness) quality. Because the main shaft branch of the company evaluated these problems and the technology research and development that at present it may pursue, the company decides to its main shaft is redesigned on the successful foundation in existing product. From Bryant company's original II acting main shaft can see a result. During the design of II acting main shaft, the main shaft branch of Bryant company listed a series of targets. The target includes to increase torque and power, those who improve scroll component is lubricant and the refrigeration of bearing and electronic component, reduce have damage the certain and specific noncombatant duty at precision. In addition, the company aims to be designed to make, raising precision while eliminate additional cost, use those to be able to raise what can forecast gender and wheelhead treatment performance " intelligence " technology. Lubricate much betterly to come true, II acting main shaft uses gas / oil-lubricated agent, every bearing has his special fuel injector to go up in order to ensure right amount lube eject designs two medium bearing to series connection bearing. This makes locomotive bearing temperature lower, and increase prestressing force make main shaft has taller tigidity, movement more flowing. Get cooling to assure bearing and electronic component, refrigerative fluid sheds II acting main shaft back and forth classics bearing box. Offerred a kind more efficient conduct heat means. The special structure of cooling passageway also makes cooling fluid more stand by bearing, benefit is heated up at coming loose from bearing better. Previously, before the water with stator crust covers bearing to participate in a loop scarcely. And in box of the bearing before main shaft, the positional place that cooling fluid is exported to be in charge of by cooling fluid is restricted. The Revelations of advanced software technology of Bryant company agrees with any adoption the machine tool that is based on PC to control a technology. The rear axle of II acting main shaft bear have the bearing before mixing to conduct heat identically means. Even if,Bryant company says the main shaft with respect to itself, use this kind to conduct heat means also is first. Box of the bearing after cooling fluid is guided directly, its course and before the circular system with same bearing -- cooling fluid comes from same source, but before, hind bearing box departure is cooling. Stator crust is packed to be in now copper makes case inside, latter leaves so that guide cooling fluid to had shed whole stator surface equably,have helix chamfer. The company says these cooling fluid passageways eliminate the quantity of heat that electric power produces effectively. In the test, II acting main shaft with 60, 000r/min arrives 90, the rotate speed of 000r/min ran 4 hours, wheelhead temperature is compared outside heighten of crock environment temperature 2 to 4 degree Fahrenheit. The waste water that the company says to come from main shaft is very hot the level that reachs untouchability, this proved the effectiveness that conduct heat. Conduct heat through improved interior make II acting main shaft can be below the 20 conditions to 40 degree Fahrenheit movement, under the main shaft temperature previously, this is in to the consideration 6, 000r/min arrives 160, it is important to comparative when the usable main shaft inside the rotate speed limits of 000r/min. The design phase of main shaft function rises in Bryant company, the company discovers the public errand of a lot of main main shaft component is more than the common difference that uses the bearing that props up them significantly. This basically is the bearing social estate that uses because of original place -- and practicable -- the precision level that does not have ABEC9 bearing place to offer. Actually, the precision of main shaft component has caustic to buy the intrinsic accuracy of bearing and service life at place. II acting main shaft uses all tall frequency now bearing of ABEC9 mixture pottery and porcelain. Public errand of crimple main shaft can increase production cost normally. But, bryant company is opposite namely after research and development its are all component has close check, can reduce cost in order to examine what new design. The company is used " error budget " concept, tall to its difficulty component tries to transform, and the spare parts of most to comparativing quantity is redesigned, in order to reduce the cost of tolerancepublic errand overlay. For example, every one aspect of the matter of bearing box is included have many opening, need completes multinomial operation. New design founded a weak opening, need to undertake from same end only abrade, removed homocentric issue. Bryant company still has many part incorporating odd a spare parts, make its design standardization, make its make a process more efficient. The Revelations of advanced software technology of Bryant company agrees with any adoption the machine tool that is based on PC to control a technology. In addition, bryant company was added for its machine tool " intelligence " technology. All Bryant grinder provided the new Revelations software of the company and Fanuc controller now, can pass aether net to be able to join to in-house user control center is mixed / or be located in Fomengte the Bryant factory of the city. Use network connection, the company can monitor the activity of area of machine tool work through acceleration sensor is being installed on wheelhead. Acceleration sensor can the vibration of inductive wheelhead, report controller, can change technology in real time so in order to assure high quality production. Thermocouple still was installed on wheelhead, before it is monitored, hind the bearing temperature of bearing. The plan installs on the machine tool in the future " black box " , it can monitor company of Bryant of the application that reachs control to assist device, blame to produce the application of equipment and other machine tool. Be in at present domain of two of wheelhead of research and development special application, nap of the emery wheel that monitor and true grinding process. Acceleration sensor can the induction arrives the little vibration of machine tool main shaft, controller can give to main shaft monitor, because this can set applied parameter. When foregone nap parameter, after athletic contrail or oscillatory signal, they are by memory in the computer and compare circularly with follow-up nap, whether be in order to decide this nap craft clean emery wheel. Still can monitor emery wheel - nap implement relation, can build during preparation is operated spark in order to save time. During itself of craft of the grinding that monitor, the workshop can use the process that monitor to decide optimal loop according to oscillatory signal and controller again. The Revelations software of the company catchs the allocation of inductive preform, original part appearance, the work requirement that decides horizontal feed differs with matching. Cutting technology: Technology of intelligent main shaft holds Introduction CEO Craig Barrett concurrently according to the president of Bryant Grinder company, this company saw the controls software weakness of company of its oneself etc, as the response to this, development went Revelations software. The company designs its Revelations software a kind of intelligence, the software package that uses easily, it agrees with any use the machine tool that is based on PC to control a technology. It has feeling screen controller and a simple operator interface, accordingly this software offers faster operator to groom, process designing time, preparation reachs cycle time and produce fewer waste material. The design aims to make interfacial navigation most simplify, convenient programmer and operator are used, this software allows a workshop to pass little the operation transfers any function or operate at 3 key-press, in order to reduce preparation and part cycle time. The reduces the G code with compact profit from and Revelations software flexibility of cycle time. Software was eliminated by machine tool program (it includes thousands of normally such inefficient statement) inside " If " the delay that statement place causes. Process designing interface has logic to be able to inspect flow chart, its design the rate that aims to accelerate machine tool process designing. Bryant company calls software automatic configuration, have infinite series function and deploy software oneself. This makes the machine tool of this company more agile, more easily operation, movement is rapidder. Revelations software undertakes automatically be configuringed afresh to oneself, so that can move on the any grinder, lathe, machining center, gear-hobbing machine, machine that insert tine or special type machine tool. Can identify the other feature of number of axle, main shaft, peripheral equipment and machine tool. Use this software, engineers can use the workstation that is based on a browser to use these data in order to collect manufacturing data to manage a machine tool. In addition, engineers still can reach product line in grinding program before, on their workstation moving spare parts emulates a program and generate production to evaluate. Use the online documentation of software, operator and safeguard personnel to be able to be visited " help " menu, pass every craft level exceed a link to examine complete documentation. Still can obtain overall hydraulic pressure from the machine tool graph, circuit graph uses a figure compatibly. CNC Milling
