It is understood that water jets have been used for the exploration of sand and clay deposits as early as around 1900. Thirty years later, high-pressure water jets were used in coal and mineral mining tests in Soviet and US mines. In the 1960s, the use of composite materials was introduced in the aircraft industry, and Boeing recommended the use of jet technology for material processing. Finally, in 1971, the first practical water jet cutting machine was invented. Today, water jet technology has been used in many industries and is highly efficient, for example in the aerospace, automotive, metalworking, electrical and food industries, and circuit board manufacturing industries. The advantages of water jet cutting are more prominent than pure water jet cutting or abrasive grain cutting. Many advantages of material segmentation Water jet technology is suitable for cutting soft materials such as textiles, synthetic rubber, fiber materials, paper or thermoplastic materials, as well as for cutting hard materials including metals, hard stone, bulletproof glass and ceramics. The thickness of the cut depends mainly on the processing material and the cutting method. In water jet cutting, different materials are often processed using the same tool, and the flexibility is greatly improved. Secondly, since the workpiece has few burrs after processing, it is generally unnecessary to perform subsequent processing. In general, the use of water jet technology for material processing can achieve high material utilization. Water Jet Sweden (hereinafter referred to as WJS) of Ronneby is one of the leading suppliers of high performance waterjet cutting systems in Europe. In 1998, it established a German subsidiary in Neustadt/Weinstra?e. WJS can manufacture systems of all sizes for different applications, such as integrated compact systems, equipment with a working range of 9m x 4m or larger, or frictional five-axis waterjet cutting machines. The user's cutting accuracy and speed requirements for the equipment are particularly high and all components must be coordinated as required. WJS uses the Rodriguez linear system to control the cutting unit. This linear system is part of Eschweiler's wide range of linear devices and drives. Excellent control device enhances competitive advantage The NC 4020 ED and 2D Jet Cutting System NC 3030 T are equipped with a gantry frame with 3 cutting heads and a Rodriguez unit in the WV or WM series. Linear unit equipment includes roll ball screw drives and linear reciprocating (circulating) ball bearing units, which are often used for material processing, especially in combination with water jet cutters, laser cutters or milling and punching machines. In the above applications, the Rodriguez system has a unique advantage, one of which is the precision ball screw drive to ensure precise positioning. The patented ball screw nut has high impact strength and long service life, while producing soft and jitter-free motion. Roller ball guiding technology provides above-average stability. In addition, the spindle support device with a feed rate of 2.5 m/s and a stroke of 11 m is also registered as a patent. All linear systems in the Rodriguez WV or WM series come standard with a central lubrication system that reliably guarantees proper functioning under harsh environmental conditions. Maintenance is particularly simple, and can be easily carried out even under limited operating conditions. The system cover is designed to protect equipment and prevent dust, dirt and water from entering the equipment. The coverage design of WV and WM linear systems is very clever, effectively avoiding the pollution of water by dust and dirt. Linear systems employ a variety of corrosion protection solutions that allow the system to function in extreme environments. Users can choose from different models depending on their requirements, all models are compatible with general purpose motors and most transmission types. Linear system with different controls Rodriguez's linear products are so rich that they are increasingly responsive to the special needs of components and components. While this requirement can also be achieved by using different linear components, linear systems are a better and more economical option. In order to be able to meet the needs of users as much as possible, Rodriguez also offers linear systems with different control types. In order to be able to meet the widest possible range of applications, Rodriguez offers linear systems with different controls. The mechanical construction of the ALS series linear system of the traditional control type requires four linear ball bearings in addition to the two precision circular controls. This linear ball bearing can be used in a variety of models and mounted in an aluminum square housing to ensure a simple and versatile line alignment task. Depending on the type of drive the user wishes, Rodriguez offers ball screw drives, trapezoidal spindles and toothed V-belts. The linear slide can be either moving (type A) or fixed (type B); it can be either bellows (optional) or without bellows. If the higher load on the system affects the linear slide, a supported precision shaft is recommended. In addition, the catalogue includes linear axes, recirculating ball guides, prismatic guides and roller guides, as well as WV and WM series linear systems.
