A2-6 Lathe Spindle (Standard) for CNC Turning Machines
The A2-6 Lathe Spindle (Standard) is a core component for high-precision CNC turning and lathe machines. Engineered for heavy-duty industrial environments, this belt-driven spindle features an A2-6 nose taper and a significant 56mm bore diameter, allowing for versatile bar work and large workpiece machining. It operates at a maximum speed of 3500 RPM, supported by a superior '4+2' bearing configuration (7018 P4 front and 7016 P4 rear) to ensure exceptional radial and axial rigidity. The 565mm total length and 170mm h6 locating diameter provide the mechanical stability required for high-accuracy metal cutting. Factory grease-packed for low maintenance and long service life, this spindle is the industry standard for reliable turning performance.

Technical FAQ & Operational Guide
What does the A2-6 designation mean?
A2-6 refers to the standard American Standard spindle nose taper. It defines the flange diameter, bolt circle, and taper dimensions, ensuring compatibility with standard A2-6 chucks and tool holders.
Why is the 4+2 bearing configuration beneficial?
The 4+2 setup (4 bearings at the front and 2 at the rear) provides extreme rigidity. This allows the spindle to handle heavy radial and axial cutting forces during turning without deflection, resulting in better surface finishes and accuracy.
Is any external lubrication required for this spindle?
No, this spindle is factory grease-packed. This 'Lubricated for Life' design reduces maintenance requirements and prevents contamination common in oil-mist systems.
