HANKOOK 7NB-3000 CNC LATHE

Technical Description

This CNC lathe features a robust 20-inch chuck size and a maximum bar capacity of 6.9 inches, allowing secure holding and machining of sizable cylindrical workpieces. It operates with two axes (X and Z), facilitating precision turning along diameter and length dimensions. Powered by a 25 HP motor, it delivers a maximum spindle speed of 1,000 RPM, accommodating moderate-speed machining with substantial torque. The machine accommodates a turning diameter up to 20.25 inches and a swing of 29.5 inches, supporting the machining of large-diameter parts. Its machining length capacity extends to 118.9 inches, suitable for long workpieces and extended operations. Equipped with a tailstock, it offers additional support for long or slender parts during turning, enhancing stability and precision. The control system utilizes a Fanuc 21iT 32-bit CNC color control, providing reliable, user-friendly programming and operation for complex and repeatable machining tasks. The overall machine dimensions are 189 inches in length, 67 inches in width, and 78 inches in height, with a substantial weight of 10,730 lbs, ensuring rigidity and vibration damping during operation. This combination of specifications makes the lathe well suited for medium to large-sized cylindrical components requiring precise, repeatable CNC-controlled turning, typically used in industrial manufacturing environments where high accuracy and surface finish are required. The machine’s size, power, and control system reflect a balance between capability and operational flexibility for a range of turning applications.
