Gantry Type Muti-head High Efficiency Waterjet Cutting Machine
3Axis CNC Cutting Platform for waterjet cutter1. Why 3rd axis is needed?Reason 1: with Z axis CNC control, system can execute " thickness" command to cut on work piece accurately.Reason 2: can execute "piercing height" command, in order to avoid nozzle being stuck, pierce on 5mm above workpiece, then cut on 2mm above workpiece.Reason 3: high up piercing, low down cutting:
pierce in higher level and cut in lower level, can avoid the unsharp edge especially for cutting mirror finished stainless steel, etc., the material which need lower down the cutting head. in order to get sharp edge.2. Water capture tankThe flatness of cutting platform will directly affect the cutting height when processing. The ideal cutting height of the head is about 1~3 mm in order to get good cut result. So the levelness of the working platform is very important. And TEENKING water jet cutting platform flatness is ensured within +/- 0.75 mm.Considering TEENKING water jet can cut 150mm thick steel plate and with the change of Y axis (500mm larger than before), it can load more than 1000 KG per square meter,In order not to affect processing, the water overflow level regulator is mounting at the corner outside of the water capture, which is easily to handle water overflow level.TEENKING automatic "water level control system" is an option, it can up/down water level in few seconds by compressed air, to realize cut under water, reduce splash and noise.3. Muti-head waterjet Motion system ball-screw: ABBA (TAIWAN), 32mm Large pitch ball-screw ,less abrasion and more silent.linear-guide: HIWIN (TAIWAN),Servo system: Yaskawa absolute encoder servo motors, from Japan; especially increased value 850W motor in Y axis . When suddenly cut-off or alarm, the position do not appear deviation.all by famous brands which provides strong basis for high accuracy and highly durability.4. Electrical components:all wires and cables: with CE or UL certificated,all sensors: OMRON (Japan), Autonics (Korea), CONTRINEX (Switzerland)all relays: OMRON (Japan)all solenoids: FeiTai(China)5. High-speed movement:advantage of Servo motor drives on the screw rotation greatly reduce the inertia and improve the precision.6. lubrication of high speed waterjet cutting machine:Since 2016, Teenking had new design for lubrication oil system, its build inside the left arm of the X-beam, it looks more fashionable and more convenient.The oil-immersed lubrication provide good lubrication, but it is only designed for screw rotate drive style but never nut rotate drive style,it also can't solve the problem of Screw natural sagging bending. So the resistance of the screw nut will become severe, and heavy abrasion and high speed rotating will destroy the machine parts.TEENKING water jet use more durable nut rotation, can guarantee high accuracy stably in five years, and also support high-speed transmission(upto 20m/min and noiseless).TEENKING use automatic centralized lubrication, infiltrate into every motion bearings and joints, ensure the machine for long durability, and provide oil alarm when lacking oil. 7. Waterproof & DustproofIn the process of abrasive cutting, the splash of the dust and water easily turn into screw and guide rail. The rusting will affect the precision of the machine.TEENKING designed good waterproof and dust proof for machine, ball-screw and linear guides are sealed up strictly, and water fender for the cutting head will avoid strong water splashing into the beam. Furthermore, stainless steel covers are equipped with rolling wheel to stable the sealing strip in fully enclosed state.Moreover, TEENKING has designed a hidden high-pressure water gun/ high-pressure air gun system at the left side Y-beam, it does not take up any useful places, because it telescopic automatically.This system is convenient and practical for all users.8. Mechanical Structure & ProtectionTEENKING water jet is mechanics designed, make sure good performance and high machine precision.In order to make machine durable, we do special UHF annealing process for machine structure, keep long time high precision performance.9. Stainless Steel Exteriora. We use abrasive to cut, the dust of abrasive mix waterwill strongly corrosive(Acidic wastewater in the water tank) and the paint peeling off, stainless steel cover will keep machine always in new condition after clean up by fabric.b. The paint is easily scraped by material loading, stainless steel cover has no paint on it and it is wearable.10. PrecisionTEENKING present very high precision for cutting, for every machine we will make test report for all accuracy which is needed, for example we cut 100mm diameter circle in 3000 mm/min high speed in each corner, the accuracy of this circle is within +/-0.05mm, and 100mm*100mm square in each corner, the accuracy couldreach up to +/-0.02mm.This is one of TEENKING company's standard acceptance way.
