Almost all had visited TNTEDM of this job shops (Plymouth, michigan) the adornment style that the person can mention its extraordinary. Natural timber adorns an entrance, smooth granite shop is in corridor, lock type lighting equipment, wall mount wainscot, the job shops of this 40 people has the atmosphere of agency, configuration as broker company or design atelier. However, the manufacturing space of the 60000 square foot of TNT accommodated more than 48 EDM however (electric spark is machined) equipment, bag vinculum cut and CNC are strong auger, and the CNC milling machine of almost same amount and machining center. Innovation of this kind of style goes " specialization " atmosphere reacted the company is opposite high quality, what high accuracy machines is important and devoted. The newest automation of TNT machined unit to represent the clever union of advanced technique and artistic style. These 7 groups of all unit include two machine tools that contain individual manipulator and circumgyrate car. Having 3 groups of unit is CNC rushs get EDM; Two groups are line cut; Still having two groups is to be used at electrode of milling stone mill. Look suddenly, these equipment are put unitly is 20 centuries typical rustic robot equipment is unit since 90 time in the workshop put way, especially class enters mould workshop. The unit of all automation equipment that resembles TNT is same, machine tool of this line cut has a manipulator and circumgyrate car between two equipment. Manipulator the flank to load from recently, see figure above. Stand by observation these equipment, can discover a few very important improvement. These improvement expanded the process capability of every equipment unit, be unmanned in charge of run offerred economy and effectiveness, offerred to equipment is safeguarded and be maintained convenient. Below most circumstance, each every task is in charge of every equipment group, such, make labor cost falls as far as possible in the scale in operating costs most bottom. Very apparent, in the competition of market of current whole world, this have competitive advantage. However, be absent however with the competition of other company this respect. Competition depends on a company be being used extensively of milling of oneself to hard metal, be replaced with what make pair of EDM or complement. Although TNT is built strictly with the mode of EDM workshop, use at plastic inject mould in great quantities, but company from 20 centuries 90 time end begins to transfer other application. Ability of hard metal milling once was the driving force of behind the curtain of this new politic way. "EDM is all in all to remaining the same for us " , the company founds explanation of president of person Tom Mullen to say, "Although hard metal milling represents our new development field, but the work that includes hard metal milling also often includes EDM treatment. " the hard metal milling that the workshop undertakes is more, efficient more important, EDM becomes more economy, his explanation says. The part of the EDM equipment unit as a result of automation is versed in Cheng is designed, make this facilities can complement to be operated with what support milling of workshop hard metal. Rely on a wall to place TNT unit does all automation to be decorated accordingly make the machine tool is located in near wall, machine tool forehead faces corresponding treatment to lie between li of side. Unit to every, a manipulator and integrated circumgyrate car are located in among two equipment. Manipulator lades and uninstall be in the machine tool is the closest at the same time. Consequently, jockey is completely OK the treatment chamfer of straightway use workbench and equipment. The movement of manipulator is by chain illume shade comes of monitoring, door of and rather than accuses or cover accuse. This kind decorates your equipment safety orderly, one can visit these facility clear. Had illume sign, the surface and mobile component collect bilge no longer or need was repaired. Circumgyrate car and manipulator lade when workpiece or electrode very easy also. Separate equipment unit the periphery between to place along treatment, make all current equipment are crossed from the back or reach a machine along wall. Air inlet duct or electrical wiring come out from wall, kept away from to receive electric cord from what the ceiling comes down, conduit or tube. Network wire cable also is decorated along the wall. Setting or redeploy equipment unit are mixed quite simply agile, because hookup is with respect to configuration on the side. Although the layout of the workshop is complete practical and the ground is firm basis craft, but structural design standard of height makes however the outward appearance that having major and have appeal more. Pipeline system also is decorated along the wall at the back of equipment unit. The workshop has central system to handle insulation liquid, it is so on the side of EDM, mix without condenser filter device occupies floor space. The pipe of 4 inches of PVC that processes insulation fluid rises equipment and central system join. A powerful person and bolt are decorated it is all and OK to be in place and the place that can reach between equipment unit and unit. Ground report sensor is decorated properly in can monitor a liquid the position of serious leak. The design of sensor is to be used prevent a liquid to flow whole lie between, if slop touchs sensor can issue warning signal, this safe device makes the operation of unmanned in charge of more on the safe side. Workshop cent machines area for a few, use the device that have special technology or sets special kind technically. Every area basically is a very large space, wall of machine tool edge is put, around the machine workbench among the move and working mesa. Strong get EDM, line cut and electrode production gather together, corresponding central system is located in adjacent position. For example, to be being used at the water of line cut, undertake cooling to its, filter and go in the center of ionic processing the system installs online cut in a room on the side of special frame. No less, rushing the oil that makes insulator is used in getting EDM, the placement of its filter and condenser area, decorate rushing get EDM to lie between on the side of between. Graphic representation is the area at the back of automatic equipment unit, it develops the public device that gives neat and easy maintenance, these public facilities are used at every machine tool. The big pipe of wall edge and system of fluid of the insulation central are linked together. Use floor space effectively to have profit very much. Equipment unit is together into the platoon of the group, discharge the wall in same wall or vicinity by, a such people with respect to in charge of of can single hand all equipment of this area. Because equipment unit relies on a wall to place, have the Yao of a few paces only from the workbench among the room so. The organization that machine workbench and working mesa are workpiece, tool and electrode is put provided enough space, won't produce crowded phenomenon. Workpiece secures the setting stage of equipment, be measured like those or detect the tool is same, place the stage around the facility that matchs to wear on. also so enough space spreads out blueprint and other file. Below table store object space is very convenient, arranged regulations in detail to prevent a disorder. Capacious corridor makes motor vehicle carriage workpiece and tool more easy. Be located in when manipulator among when, to the valuable assistant structure that gets EDM unit configuration makes equipment faces ahead. The right hand - the configuration of valuable assistant structure that left hand configures a crucial factor that assigns EDM unit is a machine tool. Unit of cut of every two lines includes a pair of Mitsubishi EDM (Wood Dale, illinois) FA10 model. Every 3 CNC develop the EA12E that gets EDM unit to include to be made to same manufacturer auger. Every are unit, a System 3R (Totowa, new Jersey) WorkMaster manipulator of production is used lade and uninstall workpiece. Manipulator is rushing in getting EDM unit, also use at changing automatically electrode. FA10 and EA12 configure the right that suspends controller in the condole that operates personnel only normally. To satisfy the requirement of TNT, construction staff agrees to also offer a belt to charge unit to the left, in order to apply to equipment unit of the group side by side layout. These improvement is by the Mitsubishi EDMs U that is located in Chicago outskirts. S headquarters is designed and in its Japanese factory is carried out. Bill Isaac of product selling manager says, the component structure that is these equipment makes improve become a possibility. The operation of equipment runs and controlling unit otherwise cannot be changed. (left hand configuration is already right now other user with special the means that order goods is open. ) in TNT, the assorted tool system of 3R system can be used at CNC to rush get and line cut equipment is unit, because its configuration was in,be workshop on all EDM equipment. The milling machine that all at electrode production using is using system of tool of this kind of combination, decide in order to ensure whole treatment process counteracts the essence in EDM treatment process and directional. Manipulator is installed with forceps, it and 3R system tool are general. Be located in when manipulator among when, to the valuable assistant structure that gets EDM unit configuration makes equipment faces ahead. Unit of milling of two of the workshop automatic stone mill also has the the right-hand side - left hand configuration. Milling machine of stone mill of CNC of Okada GM544 high speed also asks to improve condole to hang controller and to load of automatic cutting tool implement, provide space for manipulator arm. Every equipment has a pneumatic to rise in the right all round equipment or left equipment fall board, the pass in and out that is manipulator is offerred convenient. Besides among them one deserves to Nikken CNC 100 rotates workbench, make equipment has four-axle process capability besides, unit of milling of these two stone mill is identical. Development of hard metal milling is strong although the company is in,respect of hard metal process capability invests ceaselessly, mr.
Mullen has left EDM treatment without the central issue that sees a company from beginning to end. Hard metal milling reduced the average treatment amount that EDM works to every for certain, but it is very important that EDM treatment remains the same. The special section of the workshop is the production area that hot forge cutting tool and a kind of production use cutting tool, this kind of production uses cutting tool is to be used forging pulverous metal (PM) of the spare parts. With will forging the punching machine of PM spare parts and die are more more accurate than be being used at the cutting tool of general cast. Its geometry form is more complex, tolerancepublic errand is more strict. So, forging the part that production of PM semifinished product gives is more substantial adjacent at perfecting appearance. This kind of cutting tool agrees with hard metal milling, because its geometrical appearance is opposite more shallow. 5 axes treatment needs this kind of cutting tool normally, in order to reach complex geometrical figure, and in the area after EDM is machined, need not cutting tool of again additional lengthen. The workshop uses OKK3 rod machining center has thick milling order. Mill of essence of life is to be in what machining center or Hermle5 axis finish Yasda3 axis on machining center. Forging the good example that the punching machine of PM part semifinished product and die provided milling of a hard metal and EDM interact. In this kind special situation falls, lower mould has a big via. Sure should use line cut to make these hole. The dimension of these aperture and deepness eliminated to use the possibility of hard metal cutting. These aperture come out in the treatment on equipment of cut of Mitsubishi FA20 line, this equipment has the characteristic of immersion cutting: Spare parts paralell connection is fixed. Immersion cutting has an advantage, because the mouth is in a diameter the spare parts wall all around is large each have different, brought about rinse a condition unevenly, be not machine tool of immersion line cut to this very unmanageable. Through cutting replete go the slot of ionic water is internal, this method can machine a better appearance bright and clean degree, give more accurate geometry appearance with quicker cutting rate treatment. To manufacturing PM spare parts forging mould, hard metal milling replaced the many treatment work that EDM once completed, but, line cut still is used extensively in treatment of sunken model stiletto. Mr.
Mullen believes the application that hard metal milling and EDM succeed finally, depend on can be clear about the ability that understands every process and limitation. "We are exhausted can milling of applied hard metal, use EDM when necessary, " he says. The experience of his use EDM is confirmed to be the guideline that a value cannot measure, the productivity that should using hard metal milling to offer while, the improves EDM efficiency of utmost. "EDM and hard metal milling coexist at the same time here, " Mr.
Mullen says. The development of technology of cutting cutting tool, axial design and high speed CNC are controlled, can make treatment of hard metal milling more effective. In the meantime, the propulsion of EDM automation also will make this treatment craft more outstanding. CNC Milling
