Used LEBLOND-MAKINO A71 #9123563 for sale

LEBLOND-MAKINO A71 is a large, highly precise CNC machine tool with a wide range of machining capabilities. It is designed for large-scale production of accurate, high-quality components using the latest technologies such as thermal displacement compensation and automatic tool change. The machine is powered by a 79.0 hp high speed, low voltage spindle that rotates at up to 15000 rpm with high accuracy. The spindle is driven by a four-speed gearbox, allowing for precise machining in various materials. The spindle is also protected by an oil mist lubrication equipment, which helps maintain its high performance over time. It has a working envelope of 650 x 250 x 450 mm (25.6 x 9.8 x 17.7 in) and incorporates a wide range of tool capacity, including up to 12 segments in the automatic tool changer and up to 40 tools in the internal magazine. This enables the machine to carry out efficient machining operations which would otherwise require multiple set-ups. A71 utilizes the latest positioning technology, with a cutting-edge drive system composed of asynchronous linear motors and planetary commercial precision gearing. This results in radial and angular accuracy of up to 0.000000098 radians (0.000002 deg) and an unidirectional repeatability of 0.000000039 millimeters ( 0.000002 inch). Furthermore, an optional full 5-axis motorized table provides a large work envelope of 950 x 500 x 500 millimeters - perfect for complex machining operations such as cylindrical boring and shaping. LEBLOND-MAKINO A71 is equipped with state-of-the-art grinding spindle, allowing for sensitive and accurate finishing operations. This machine also has a maintenance-free design, with a closed-loop cooling unit and a lead screw that keeps vital components free of contamination. For additional ease of use, A71 is fitted with an intuitive control machine, providing a user-friendly operation with a high level of flexibility, accuracy, and speed. It is also compatible with Windows and UNIX, making it suitable for efficient integration into any production environment. In conclusion, LEBLOND-MAKINO A71 is a large and efficient machine tool suitable for precise high-volume production of quality components. Its cutting-edge features make it ideal for complex machining operations and allow for precise positioning control and low maintenance. The intuitive control tool provides outstanding flexibility and accuracy, making sure that each operation is performed quickly and with no errors.
