LUNAN XK7145A VERTICAL MACHINING CENTER

Technical Description

This CNC machine features a BT40 taper spindle, providing medium-duty milling capability with enhanced rigidity and balance due to its symmetrical 7/24 steep taper design. The machine's XYZ travel dimensions are 27.56 inches (X-axis), 17.72 inches (Y-axis), and 19.69 inches (Z-axis), supporting a versatile working envelope suitable for a range of machining tasks. The spindle operates at a maximum speed of 8,000 RPM, enabling efficient machining of various materials with precision. The BT40 interface is compliant with JIS B6339 standards, ensuring compatibility with a broad range of tooling and reliable clamping through a metric threaded retention knob (M16 thread). This taper provides excellent tool holding stability, minimizing runout and vibration for enhanced surface finishes and extended tool life. The CNC control system supports automated, programmable operations, enhancing machining accuracy and repeatability for complex and high-precision tasks. The spindle’s moderate max rpm suits applications requiring both torque and speed without compromising toolholder integrity or machine stability. Overall, this configuration balances work volume capacity, tooling versatility, and spindle performance, making it ideal for medium-scale milling operations demanding a combination of speed, precision, and toolholder stiffness. Specifications such as case-hardened tool holders with precise taper grinding (AT3 tolerance) ensure reliable high-speed performance and durability under continuous operation.
