ACM Waterjet cutting machine
The water jet cutting machine is constructed from a precision steel structure and equipped with direct drive linear motors on each of the two main axes (X and Y). For accuracy, the gantry and the self-driven carriage plate are driven on both sides by two direct drive linear motors. This achieves a speed of 1-30,000 mm/min. The use of the above components and constructions results in a positioning accuracy and repeatability of ± 50µm (at 20 °C). The guides and drives are adequately protected by bellows and protective stainless steel plating against the effects of water and abrasives. Direct linear motors guarantee: - Better cutting behaviour and absolute repeat accuracy (no backlash) of the cutting head position compared to traditional mechanical transmissions using spindles, pinions, racks and gears - Low maintenance due to the non-contact principle, combined with a significant reduction in wear parts - A wide range of cutting speeds and jogging speeds, adjustable from very low to very high - Fast response, enabling rapid changes in cutting speed. Unmanned operation Because the high-pressure pump and process parameters are monitored automatically, permanent supervision is no longer required during the cutting process. Resato waterjet cutting machines are equipped with an automatic stop that is activated after completion of a cutting job and have the optional possibility of transmitting this via an SMS message. Any malfunctions can also be reported via this option.
ACM Flex-Zone
ACM Flex-Zone = Greater efficiency in a safe environment Previously, the table was inaccessible during cutting, but with the Flex-Zone, loading and unloading can now be carried out safely during the cutting process. This minimises downtime while optimising production and operator working time. Light curtains are normally installed around waterjet cutting tables to ensure operator safety. With the Resato ACM Flex-Zone, the safety feature is mounted on the bridge itself. It moves with the working area of the cutting head. The Flex-Zone creates flexible, accessible working areas on the cutting table during cutting, allowing operators to access the table. The ACM Flex-Zone: Greater efficiency in a safe environment! More efficient cutting process Unmanned operation Cleaner working environment Operation The ACM Flex-Zone projects a light curtain at the front and rear of the bridge at a standard distance from the cutting head and bridge. Breaking this light curtain while the machine is in operation results in an immediate stop of the cutting head and servo motors, ensuring safe access to the parts on the bridge. The protected zone can be released in a few clicks via the panel so that cutting can be resumed. While the cutting process is in progress, the operator can load and unload outside the safety zone.
2.5D cutting head
The 2.5D cutting head is designed to cut bevels from material. Two additional servo-controlled axes are added to the standard XYZ axes, creating a five-axis machine. A height sensor is integrated to ensure practical application. The integrated, high-torque, frameless servo motors with hollow shafts form the core of this unique construction. Using the direct drive principle results in a minimum of moving parts, resulting in a compact, highly accurate, fast-responding and maintenance-free solution. The cutting head can be tilted up to 55°, the practical limit when cutting a 45° angle on a 90° contour angle. Abrasive and pure water compatible Modular design Highly accurate Compact solution ACM backward compatible EMS System The electronic feeder (EF) is equipped with the EMS electronic monitoring system, which is specially designed for unmanned operation with the ACM cutting table. In combination with the cutting head, all important cutting parameters can be monitored. The EMS monitoring system detects a broken water nozzle or a blockage in the abrasive supply in good time, triggering an alarm and automatically stopping the cutting process if necessary.
2D cutting head
The cutting head has a Long Life mixing chamber containing a water nozzle and the abrasive mixing tube. The cutting table portal has 1 or 2 cutting heads mounted on their own carriage plate. Both carriage plates are equipped with their own direct drive linear motors. This makes it possible to quickly and easily set the correct distance between the two cutting heads from the control console. This distance varies between 350 and 1500 mm. A special feature of 3-metre machines is that even with 2 cutting heads, the useful cutting range of 1 head is still 3 metres in a 2-D cutting position. Abrasive and pure water compatible Modular design Highly accurate Compact solution Electronic feeder To optimise cutting speed and quality, each cutting head is connected to an electronic abrasive dosing system (feeder). This system is mounted on the carriage of each cutting head and equipped with a small integrated buffer to ensure a reliable, consistent and continuously adjustable abrasive supply.
ABR-CS
The continuous abrasive system allows the abrasive pressure vessel to be refilled without interrupting the cutting process. The tank contains an automatically controlled pressure system to fill a smaller pressure tank that transports the abrasive to the water jet cutting machine. The large abrasive storage silo stores the abrasive and can be refilled at any time without interrupting the cutting process. On request, the ABR-CS with switch box can supply abrasive to up to three machines. Continuous abrasive supply Able to replenish abrasive during the cutting process Monitors the abrasive level Silo low-level message To check whether there is sufficient abrasive stored in the storage silo, a sensor sends a “Silo Low-Level” message to the cutting machine. This message triggers the storage silo to be filled before it runs out of abrasive.
PJ4-4000
The PJ high-pressure pump operates according to the pressure intensifier principle. The pressure intensifier is driven by a hydraulic pump with an electric motor. The intensifier converts the oil pressure into a water pressure that can be regulated between 300 and 4000 bar. A pressure-compensated hydraulic axial plunger pump is driven by an electric motor with a nominal power of 30 kW and a maximum oil pressure of 200 bar. The hydraulic pump is equipped with electronic pressure control and a safety valve that depressurises the system when the pump is switched off. Excellent cutting quality due to minimal pressure fluctuations. This is achieved by optimising the stroke volume, high-pressure accumulator and electronic switching of the pressure intensifier. Easy access to all important components thanks to ergonomic design and working height. User-friendly operation. Very low noise level: <72 dB. Accumulator To minimise pressure pulsation in the system caused by switching the intensifier and opening and closing the cutting head, an accumulator with a capacity of 2.5 litres is integrated into the system. The accumulator has been proven to significantly reduce wear.
RS-3
The RS abrasive removal system, equipped with a single filter, consists of a special suction and pressure pipe system, which is fitted with a number of inlet and outlet nozzles mounted in the water tank of the cutting table. The size of the water tank determines the number of inlet and outlet nozzles. For larger water tanks, the inlet and outlet nozzles are automatically controlled per section by means of a pneumatic valve system. The water/abrasive mixture pumped out of the water tank is collected in a free-standing separation unit equipped with a filter (known as a Big Bag). The used abrasive sand is sucked out of the water tank and pumped to the RS system. In the RS3 system, the sand settles in a big bag and the remaining water is pumped back to the water tank. The RS3 system is switched on and off and adjusted from the control console. The Big-Bag filter can be easily removed from the separation unit. Optional on all ACM series machines Reduces downtime to a minimum Reduces the need for tank cleaning Optimal distance The maximum distance between the connection points of the cutting table and the RS3 separation unit is approx. 6 metres. This distance is necessary to ensure optimal operation.
Abrasive vessel
The abrasive is transported from the container to the feeder by means of air pressure (4-5 bar). If there is insufficient abrasive in the storage container, a low level warning appears on the control console. If this warning is ignored, the abrasive will fall below the minimum level, causing the cutting process to be interrupted automatically.
Igems cutting software
The efficiency and speed with which cutting orders can be carried out is largely determined by good work preparation. That is why Resato supplies the IGEMS CAD/CAM software package, which has been developed specifically for waterjet cutting. The software package is fully installed on your PC, which is also equipped with software for sending and retrieving the cutting programmes to and from the CNC control. The PC is connected to the CNC control via a cable. Important features of the IGEMS standard software are: Quick and easy operation including drawing facilities Fast and logical working method, i.e.: Importing workpieces Assigning material type and thickness Quick and efficient manual nesting Automatic generation of the CNC programme Transferring the CNC programme to the cutting machine Importing DXF, DWG and IGES files Determining the machinability of a particular material by means of a single test cut The machinability determines: The cutting speed Deceleration and acceleration in corners and small circular arcs
