High Precision Slant Bed CNC Lathe Machine with Taiwan Technology (BL-S40/50)
Description
-Super compact structure, big inside space, modern appearance
-Adopt Taiwan technology, designed by Taiwan engineer, most parts adopt Germany/Japan/Taiwan brand.
-Adopt 30°integral slant bed design(structure similar as Japan TAKISAWA 106), high rigidity, good machining flexibility, easy for chip conveying.
-For S50, XZ axes adopt ROLLER type linear guideway, spindle adopt ROLLET type bearing, super high rigidity
-Adopt modularization design, has strong extended function, easy for various especial configuration choice, such as tool setter, parts catcher, robot etc.
-Adopt HT300 resin sand cast iron, after aging treatment and FEA analysis, small distortion, good torsional strength, good heat stability.
-Base adopt multilayer strengthening rib, ensure bed’s strength and stability
-Frame adopt oil-coolant separation design, adopt independent coolant tank
-Adopt high precision integral spindle unit, spindle motor adopt high performance servo motor, big output torque,
High speed, wide adjustment range
-Adopt high precision pre-stretched ball screw(double nuts), coupled with feeding motor directly by linkager, no gap, high transmission rigidity, can realize μ class precise turning.
-Adopt high precision wide linear guideway, high rigidity and long using lifespan, fast moving speed, good accuracy holding, suitable for heavy loading and precise machining
-Adopt Hydraulic-servo tool turret, fast tool changing, good repeatability, high efficiency.
-mount energy-storage tank, reduce pressure fluctuation during tool change
-Can mount right-setting or back-setting chip conveyor, strong chip conveying capacity
