Used LEBLOND-MAKINO A77 #9121788 for sale

LEBLOND-MAKINO A77 is an advanced machine tool designed to deliver simultaneous 5-axis milling and turning speeds of up to 3,000 RPM, along with high-precision accuracy and repeatability. Accommodating up to 400 tools, the machine is capable of milling complex geometries with a spindle torque of up to 350 ft-lbs. The machine is built on a standard gray cast iron base for optimal dynamic performance. The robust spindle drives, along with a triple counterbalance and active-equipment motorized damping increase the accuracy of the cut while reducing vibration. Additionally, a forced ventilation system and active thermal control ensure that temperatures remain consistent throughout operation to minimize thermal error. A77 is powered by a low-speed, high-torque 12,000 rpm spindle motor with a maximum thrust capable of 1,800 lbs. Driven by a CNC-controlled servo motor, the spindle runs on a high-precision ballscrew and is equipped with an infinitely variable speed control. The spindle motor is linked to a central processor to optimize processing tools and ensure total unit accuracy. LEBLOND-MAKINO A77 features a large working envelope with a 26" x 25" table and a maximum tool height of 12.5" to enable machining of large parts. The machine is operated by a dual-screen graphical user interface with interactive menus and comprehensive operational training programs in a number of languages to enable its quick and easy operator setup and programming. Along with its advanced cutting capability, the machine is also equipped with a host of safety features. These include machine guards, hand wheel operator safety and a comprehensive interlock machine to ensure the safety of the operator. Additionally, a number of trunnion-mounted options available for A77 make the machine suitable for a variety of applications, such as peg and bore machining, patternmaking, and tooling.
