CK4346, CK4356 CNC crankshaft connecting rod neck lathe

This machine tool is mainly designed for the semi precision machining and precision turning of crankshaft connecting rod necks (including the outer circle of the connecting rod neck; the side of the connecting rod neck balance block; the step surfaces, rounded corners, and countersunk grooves on both sides of the connecting rod neck) using a two coordinate continuous control CNC lathe. The configured CNC system is capable of interpolating straight lines, oblique lines, arcs (turning cylindrical surfaces, rotary surfaces, spherical surfaces, conical surfaces), and turning metric imperial threads for straight and conical surfaces, suitable for machining crankshaft parts such as connecting rod necks. It has the function of replacing rough grinding with precision machining.

The machine tool adopts a 45 degree rear inclined bed, which is easy to operate and adjust, has good stress state, and is conducive to chip removal. The longitudinal and transverse guide rails are high-precision heavy-duty quenched plastic coated sliding guide rail pairs, which improve the rigidity of the machine tool and extend its service life; The CNC system is driven by AC digital and fully closed-loop control, stable and reliable, with strong anti-interference ability. The system has functions such as pitch error compensation, constant linear speed cutting, fixed cycle, direct drawing size programming, DNC communication, etc.
