PRECITEC SRI CHAKRA 4000 CNC LATHES

Technical Description

This CNC lathe features a machining length of 157.48 inches and a turning diameter of 23.62 inches, supporting robust production of large and complex workpieces. Equipped with a 13.78-inch chuck, the machine ensures secure workholding for a wide range of part sizes. The spindle delivers 29.5 hp, providing ample power for demanding turning operations. The machine is outfitted with a tailstock for additional support during long-part machining, enhancing accuracy and rigidity. Control is managed by the FANUC Oi CNC system, known for its reliability, ease of use, and advanced features such as up to 4 simultaneously controlled axes, linear and circular interpolation, tool compensation, and flexible feed control. The FANUC Oi system also supports part program storage, MDI operation, DNC, and a suite of safety and monitoring functions, including emergency stop, overtravel protection, and energy monitoring. The lathe’s 2-axis configuration is optimized for efficient turning applications, while the FANUC control enables high-speed auxiliary functions, rapid traverse rates, and precise feedrate override. Additional features include backlash compensation, stroke limit checks, and programmable acceleration/deceleration for smooth motion control. The system’s user-friendly interface and customizable screens simplify operation and programming, making it suitable for both basic and advanced machining tasks. This combination of size, power, and advanced CNC control delivers high productivity, accuracy, and versatility for a broad spectrum of turning applications.
