Used COBURN SGX #9253497 for sale

COBURN SGX is a highly advanced machine tool designed for precise grinding of hard and abrasive materials. It is equipped with a special spindle that features solid-state electronics, with three-phase current at high frequency to achieve higher RPMs than conventional grinding motors. The spindle is held in an ultra-precision support that features an optically matched air bearing for improved precision, repeatability, and rigidity. The machine also uses a unique flexure table equipment that is driven by two servo motors. This allows for faster table traverse speeds and better precision when machining complex components. The machine is built around a high-speed, high-torque, direct-drive CNC grinding spindle. The spindle is equipped with three independent axes controlled by Siemens SINUMERIK 840D CNC. It features an integrated system for automatic tool changing, enabling quick production without costly mid-cycle tool changes. The spindle also ensures an excellent balance of torque and mass to achieve high rotational speeds. This allows for reduced machining times and increases the cutting efficiency of the machine. SGX also features an integrated wheel-dressing unit that helps maintain a consistent part quality across the job. The machine can be used with dressing stones for grinding shape and form, wheel radius, concave, and contour dressing. There is also a coolant tool included in the machine, to help cool down the spindle and wheel and ensure a consistent cutting surface. COBURN SGX is engineered and built to be extremely precise and reliable. It has been designed with advanced thermal modeling and trapped heat monitoring to ensure that the machine operates smoothly and safely while working with hard and abrasive materials. The machine also features a rigid setup design and unique vibration control for increased accuracy in machining. SGX is designed to perform difficult jobs and can be used for various applications including profile grinding, thread grinding, cam lobes grinding, cylinder head grinding, gasket faces grinding, and more. It is also capable of machining other materials such as tungsten carbide and ceramics. The machine is suitable for use in any production line, and can help to increase efficiency and reduce downtime.
