High Precision Spindle
All JULANG ATC vertical lathes adoptcrossed roller bearings(rotary table bearing),ensuring the spindle achieves high radial and axial load capacity at both high and low speeds, delivering high precision, low noise, and durability. Features high precision, high load capacity, and high rigidity, suitable for large and asymmetric workpiece machining.
- ● Radial single bearing design, poor radial load capacity, difficult to stabilize precision
- ● Bearing force point far from workpiece, difficult to ensure machining precision
- ● Small action point distance, low anti-overturning moment, poor heavy cutting performance
- ● Axial-radial bearing has high friction resistance, prone to heating, causing axial thermal deformation and affecting machining precision
- ● Bearing wears quickly, short service life
Crossed Roller Bearings Characteristics
- ● Uses American TIMKEN patented technology with Teflon bearing cage, low friction and inertia, rotatable under low torque
- ● Large force point distance, can bear axial and radial loads, solid spindle support, suitable for long-time heavy cutting
- ● Double-row crossed rollers occupy single-row space, reduced machine height, convenient operation, low workpiece center of gravity, small centrifugal force
- ● Uniform heat conduction, low bearing wear, long service life
- ● Double-row tapered roller design, low heat generation, good heat dissipation, stable precision. Easy to control the dimensional and geometric accuracy of machined workpieces
Lubricating Oil Filtration Device
- ● Filters impurities in lubricating oil, extending spindle service life. If blockage occurs, automatic detection and alarm
Spindle Oil Temperature Control System
- ● lubricating oil cooler,Precisely controls spindle oil temperature, ensuring stable machining precision
