LUNAN CLK6440A CNC LATHE

This CNC spindle features a **bar capacity of 2.05 inches** and a maximum rotational speed of **4,000 RPM**, making it suitable for moderate-speed machining applications. The spindle is **CNC controlled**, enabling precise speed regulation and operation integration with computer numerical control systems for automated and repeatable machining processes. It incorporates precision bearings and a robust spindle shaft for reliable performance and tool stability during operation. The spindle design supports efficient torque transmission within its rated speed range, ensuring consistent cutting force and surface finish quality. Cooling is typically designed to be air-cooled to maintain optimal thermal conditions at moderate speeds, preventing overheating and extending tool life. This spindle is ideal for machining materials requiring medium bar capacities and moderate RPMs, such as certain metals and plastics, where both accuracy and torque control are critical. Its CNC control interface allows seamless communication with VFD (Variable Frequency Drives) for speed adjustments and directional control, improving process flexibility and precision. The 4,000 RPM max speed suggests suitability for heavier cuts rather than high-speed precision micromachining, aligning with applications where cutting diameter and torque take precedence over ultra-high spindle speeds. Overall, this spindle balances moderate bar capacity and speed with precise CNC control to support reliable, repeatable machining in versatile environments.
