As we have learned, be in early efflux of or so water had begun to be used at deposit to arenaceous stone and clay exploration 1900. After 30 years, high-pressured water efflux is used in the coal of Russia and American mine and mineral exploitation experiment again. Era was in what composite material introduced in aircraft manufacturing industry to use 1960, boeing company suggests use fluidics undertakes material is machined. The machine of water efflux cut that palpability can use actually the first times was sent 1971 finally. Today, fluidics has used water at a lot of industries, and efficiency is very tall, mix in treatment of aerospace, car, metal, electric equipment for example food industry and circuitry board the domain such as manufacturing industry. relatively cut of Yu Chunshui efflux or the cut that wear bead, the dominant position of water efflux cut is more prominent. Material intersected is a lot of advantage water fluidics already comfortable at cut weak data, be like textile, synthetic rubber, fiber material, paper or thermoplastic material, comfortable also at cut hard data, include metal, hard stone, ballproof glass and pottery and porcelain. The ply of its cut basically depends on treatment material and cut method. In water efflux cut, the treatment of different material often is used same kind of cutting tool, nimbleness rises greatly. Next the burr as a result of the workpiece after treatment is few, do not need to undertake sequel is machined again commonly. Overall will tell, use water fluidics undertakes material treatment can achieve very high overall material utilization factor. Company of Ronneby city Water Jet Sweden (company of WJS of the following abbreviation) one of main suppliers that are system of cut of efflux of European high-powered water, are its in 1998 Neustadt/Weinstra? E established German branch. WJS company can make the system of all sorts of dimension for the different utility of the user, if compositive type is compact,limits of system, work amounts to the facility with 9m × larger even 4m to perhaps chafe type machine of cut of efflux of 5 axes water. The user demand to the cut precision of equipment and speed is particularly high, all components must undertake harmony by the requirement. WJS company used Rodriguez linear system to realize unit to cut control. This linear system is the component of the linear parts of an apparatus with wide range of Eschweiler company application and actuating device. NC 4020 ED of exceedingly good advantage of competition of control equipment promotion and NC 3030 T of system of 2D efflux cut all contain the dragon door frame of 3 cut head, the Rodriguez that introduced WV or WM series is unit (graph 1) . Linear and unit equipment includes a staff of type ball silk gearing and linear reciprocate (circularly) ball bearing is unit, they often are used at material treatment, especially with machine of water efflux cut, Laser Cutting machine or milling machine and strong trigger union are used. In afore-mentioned applied domains, rodriguez system has distinct advantage, it is lever of accurate ball silk firstly gearing assured exact location. Graph the 1 fluidics that uses at accurate cut: What the linear system that WJS company uses Rodriguez will realize unit of the cut on NC 4020 ED of machine of cut of 2D dragon door is oriented the impact resistance of nut of ball silk lever that registered patent is tall, service life is long, can produce softness at the same time and move without what shake; Grounder directs the technology can provide the stability that exceeds average level. Additional, feed speed is 2. 5 M/s, the journey amounts to the main shaft of 11 M to propped up device to register patent as much. All linear systems of Rodriguez company WV or WM series all mark distributes central lubricant system, below harsh ambient conditions, the normal play that also can assure a function reliably (graph 2) . Care and maintenance is particularly simple, although be below the condition with operation limited space,also can undertake easily. Design of systematic outer garment is clever, can protect facility effectively, prevent dirt, dirty content and water to enter facility. Of graph 2 WV and WM linear system enclothe a design very clever, prevented dirt and dirty thing effectively linear to the pollution of water system adopted a variety of anticorrosive protection plan, can make the system also can work normally below extreme environment. The user can select the product of different type according to demand, all model all are mixed with general electromotor most transmission type is compatible. The linear product of the company of linear system Rodriguez that can supply different control equipment is very rich, can contented user more and more incline to at the special demand to package and component. Although this one demand is OK also,come true through using different linear component to come, but linear system is a kind of function better and more economic choice. To can satisfy user requirement as far as possible, rodriguez company still provides the linear system that uses different control type. To can be satisfied as far as possible wide scope of application, rodriguez company can provide the linear system that uses different control equipment. The mechanical construction of the system of ALS series linear that uses conventional control type sets, outside be being controlled except two accurate circles, use 4 linear ball bearing even. This kind of linear ball bearing can have a variety of type, installation makes quadrate case in aluminium in, in order to assure simple and of diversification finish linear and oriented job. According to the drive form that the user hopes, rodriguez company can offer main shaft of gearing of ball guide screw, echelon and the form such as the V belt that take a tooth-like part of anything. Its linear slide carriage can be mobile already (A) also can be fixed (B) ; Can be to take moire valve already (equipment option) also can be not to take moire valve. Be like the bear with more expensive system to be able to affect linear slide carriage, suggest to use the accurate rod that has support. In addition, the catalog that offer money still includes ball of linear axis, loop slideway of form of oriented, arris and roller slideway, also include WV and system of WM series linear. CNC Milling
