Gmu400 High Precision CNC Milling Machine Lathe for Metal Hardware

GMU400 CNC Vertical Machining Center Supply 5axis Milling MachineIntroductionAchieve high-accuracy five-axis simultaneous machining.Featuring a high-rigidity fixed beam gantry structure, the GMU-400 Fearless series can realize high machining performance and contour accuracy under highly dynamic conditions with high accuracy, performance, and efficiency. More importantly, the GMU-400 is equipped with the outstanding GTRT gear transmission cradle technology as well to present an A-axis torque of 1056N.m and a C-axis torque of 432N.m. From any difficult-to-cut material to the highest surface quality required by mold manufacturing and even the nearly exacting contour accuracy, the GMU-400 Fearless series can deal with them perfectly.Finite element analysis combined with dynamics optimization to ensure high rigidity, high accuracy, and high stability. 1. High-rigidity fixed-beam gantry structure is adopted to achieve excellent rigidity, thermal symmetric stability, and high-efficiency vibration suppression. 2. An integral cross beam with a closed section to eliminate redundant mass and achieve high rigidity. 3. Moving parts optimized in terms of weight to achieve perfect dynamic performance. 4. Z-axis optimized in terms of  mechanics and dynamics to gain 30% more rigidity and dynamics than similar models. 5. Extra-large  area of vertical column base to provide stronger rigidity and stability. 6. Finite element analysis, calculation and optimization of whole-machine structure and moving parts to achieve high milling efficiency, high machining performance, and extreme accuracy. 7. First-order natural frequency of the whole machine  up to 67HZ, which has greatly improved the anti-seismic performance and  the static and dynamic rigidity of the machine tools. 8. Three-axis acceleration up to 1.2G. GTRT Gear Transmission Rotary Table Technology.The GMU-400 has adopted the GTRT gear transmission rotary table technology for the first time in its class. Compared to the conventional rotary table drive ones, it can present greater torque output, higher rigidity, higher stability and better rotation precision. GTRT gear transmission rotary table A-axis: Servo motor + DIN5 grade grinding gear (two-stage anti-backlash  patented technology) C-axis: Servo motor + DIN5 grade grinding gear (two-stage anti-backlash  patented technology) Travel (A/C): ±120°/360° Maximum RPM (A/C): 20/30rpm Maximum torque (A/C): 1056 /432 N.m Accuracy (A/C): 8"/4" Bearing capacity: 120kg Easy operationBased on ergonomic design, it has achieved extraordinary processing proximity and visibility as well as unrivalled ease of operation experience.Detail ImagesApplication FieldsIt is widely used in the processing of 3C products, aluminum alloy products, die-casting products, auto parts and so on.It's applicable for high-speed drilling and tapping processing.Technical SpecificationsNameUnitGMU-400X/Y/Z-axis travelmm450/500/350A/C-aixs travel °±120/360Spindle nose to table (when A axis is at 0 degree)mm150-500Table sizemm0400Maximum load bearingkg120SpindleSpindle (standard)Maximum spindle speed/taper shankrpm30000/HSK-E40Spindle power (S1/ S6 - 40%)KW10/13Torque (S1/ S6 - 40%)N.m5.5/7.1Spindle (optional 1)Spindle (optional 1)Spindle (optional 1)Maximum spindle speed/taper shankrpm40000/HSK-E32Spindle power (S1/ S6 - 40%)KW6.3/7.6Torque (S1/ S6 - 40%)N.m4/4.8Spindle (optional 2)Spindle (optional 2)Spindle (optional 2)Maximum spindle speed/taper shankrpm24000/HSK-A63Spindle power (rated)KW15.7/18.8Torque (rated)N.m25/30Feed systemX/Y/Z-axis rapid feedm/min30/30/20Maximum cutting feed ratem/min10Accelerationm/s25Maximum cutting feed rateRPM/min20/30Positioning accuracy / Repeated positioning accuracy  VDIDGQ3441/iso 230-2X/Y/Zmm0.006/0.003A/CARCSEC8/4Automatic tool changing systemNumber of tool positionsPCS16TTool change time (tool-to-tool)sec4.5SMaximum tool lengthmm200Maximum tool diameter /adjacent no toolmm060/0100Maximum tool weightkg3Machine sizeOverall machine heightmm3100Floor area (Length × Width)mm^23100x2400Net weightkg8000Power demandkw25Configuration ListNO.Standard ItemsOptional Items1Siemens 840D SystemHeidenhain TNC640 system2Uncapped full enclosure machine body sheet metal (including water tank)HSKE32-40000RPM electric spindle33HSKE40-30000 RPM electric spindleHSKA63-24000RPM electric spindle4A/C cradle-type rotary tableCapped full-enclosure programmable top guard5Spindle cooling systemLaser-type tool setting gage6A/C-axis optical scaleSafety gate switch7Five-axis calibration kitOil collector8Three-axis linear optical scaleOn-line measurement9Z-axis balance systemFive-axis anti-collision function10Electric cabinet constant temperature systemPower-off retraction system 11Pneumatic systemCoolant through spindle (CTS)12Automatic lubrication systemScraper type chip conveyor13Machine cleaning water gun 14Machine cleaning air gun 15Working light 16Warning light 17Tool box and foundation bolts 1816T horizontal umbrella-type tool magazine 19Drawer
