Product Description PRODUCTION DESCRIPTIONThe four linear motion axes of the machine tool are:Lateral movement of the column (X-axis);The headstock moves vertically up and down (Y-axis);The ram moves axially (W axis);The boring axis moves axially (Z-axis)MAIN TRANSMISSION: The main transmission of the machine tool is driven by SIEMENS AC spindle motor, and by mechanical transmission, it can obtain 2 ~ 1200r/min stepless speed regulation range to meet the processing requirements of different processes.The main transmission adopts three-speed hydraulic transmission, with wide transmission range, high spindle speed and large output torque; In order to ensure the rotation accuracy of the spindle and the stability and reliability of the rotation accuracy, the machine also adopts a special constant temperature oil circulation cooling method to force cooling of the spindle shafting to reduce the thermal deformation of the spindle system.LINEAR FEED MECHANISM: through the high speed ratio precision gear reduction box, the gear engages with the rack to achieve linear X-axis movement and effectively eliminate reverse clearance; The rack is a grinding hard tooth surface helical rack to ensure X axis accuracy.LUBRICATION: the main shaft bearing of the machine tool is lubricated with imported oil; The transmission gear and bearing of the headstock are lubricated with oil. Guide rail, ball screw nut pair are all lubricated by timing and quantitative automatic lubrication pump, the lubrication effect is stable and reliable.MACHINE PICTURES PARAMETERSITEMSUNITTK6920Boring Spindle Diameter mm?200mmMilling shaft end diametermm?320mmBoring Spindle TapermmISO 60Install the Cutter handle model JT60Blind rivetmmD60 DIN69872Maximum feed resistance of boring shaftN55000Boring shaft speed ranger/min2~1200Maximum torque of boring shaftN.m12000Boring shaft axial travelmm1200Boring shaft feed speed rangemm/min0.5~4500RAM (Z-Axis)Section Dimension mm480*520Axial travelmm1200Feeding Speed Range mm/min0.5~4500Fast Moving Speed mm/min6000Z and W axis superimposed travelmm2400Spindle Box (Y-Axis)Vertical travel of Spindle Boxmm4000Feed range (stepless)mm/min1~6000Fast Moving Speedmm/min8000Column (X-Axis)Column Travel mm8000Feed range (stepless)mm/min1~6000Fast Moving Speedmm/min8000Electrical CNC Control shaft 6-Feeding axes Universal driving shaft 4 axes (any)Mian Motor Power Kw74Machine Weight kg95000Feedback System X-Axis Full closed-loop control, grating scale feedbackY-Axis Full closed-loop control, grating scale feedbackZ-Axis Full closed-loop control, grating scale feedbackW-Axis Semi-closed loop control, motor encoder feedbackMachine Accuracy Linear Positioning Accuracy 25μmRotary positioning accuracy 8"Linear Repeatability Positioning Accuracy 20μmRotary positioning accuracy 6"MACHINE CONFIGURATIONNAMESPECIFICATIONUNITQTYBRANDSpindleΦ200Set1HubeiSpindle BearingNSKSet1German / Sweden /CNC ControllerSINUMERIK 828DSet1GermanFeed servo motorSIEMENSSet1GermanMain motor and driverSIEMENS 74KwSet1GermanGrating ruler, circular grating Set1SpainRackAPEXSet1TaiwanMain hydraulic components (pump valves)ZM1002/S2Set3KEZHENGoperation panel10.4 inchSet1German SIEMENSball screw Set1NanjingScrew bearing Set1GermanLow voltage electrical appliancesY-axis shieldSet1Germanlimit switchEUCHNERSet1Germanwireless hand pulsebattery poweredSet1Domestic well-known brandsdrag chainfully sealedSet1Hebeioil coolerReboSet1BoajiIndustrial Air ConditioningReboSet1BoajiY-axis Protection CoverInner organ outer steel push-pull coverSet1Domestic well-known brandsMACHINE FEATURESThe column is a large section of double wall design, both vertical and vertical are covered with reinforcing bars, with sufficient bending and torsional strength.MACHINE GUIDE RAIL: The movement of X axis adopts static guide rail, which has high static stiffness, improves the rigidity of the guide rail and extends the service life of the guide rail. The moving guide surface is inlaid with zinc base alloy plate, which can protect the guide rail of the machine tool.MAIN SHAFT SHAFTING: the main shaft shafting adopts a two-layer structure that is hollow main shaft and boring shaft. The structure accuracy and rigidity are good. The main shaft bearing adopts imported bearings with good rigidity and high precision. MACHINE GUIDE RAIL: The movement of X axis adopts static guide rail, which has high static stiffness, improves the rigidity of the guide rail and extends the service life of the guide rail. The moving guide surface is inlaid with zinc base alloy plate, which can protect the guide rail of the machine tool.The machine adopts ram headstock mobile structure, and the headstock adopts integral inclusion structure, which contains the ram in the box, improves the overall rigidity of the ram structure, and is conducive to the machine tool for strong cutting.
