SHENG HONG CK6140 CNC LATHES

Technical Description

This CNC machine features a swing of 12.99 inches and a machining length of 29.52 inches, making it suitable for a wide range of turning operations on medium-sized workpieces. The machine is equipped with the Siemens SINUMERIK 802C control system, a microprocessor-controlled numerical control designed for economic machine tools with analog or stepper motor drives. The 802C control provides reliable operation with support for up to three analog axes and an analog interface for the main spindle drive, enabling precise control of machining parameters. The system includes an NC operator panel with a graphics display and keyboard, a machine control panel, and digital I/O modules for expanded connectivity. The control outputs analog setpoint signals in the range of ±10 V for axis and spindle drives, with relay contacts for servo enable functions. Environmental operating conditions are rated from 0 to 55 °C with 5–95% relative humidity (non-condensing), ensuring stable performance in typical workshop environments. The CNC unit measures 420 x 300 x 83 mm and weighs approximately 900 g for the ENC component, with additional weight for the operator panel and I/O modules. The system supports digital inputs and outputs via 10-pin connectors and features status LEDs for fault and operation monitoring. The Siemens 802C enables straightforward configuration of machining technology data such as spindle speed, cutting speed, and feedrate through dedicated screen forms, ensuring optimal setup for manual and automated machining tasks. This combination of robust construction, versatile control, and user-friendly interface makes the machine ideal for precision turning applications in industrial environments.
