CNC Heavy Duty Lathe Machine

The main feature of the model CK61100 is that its entire width are large with a guideway width of 600-755mm; it is cast using a high-purity compound composite material and artificially aged at least two times to remove all interior stresses so as to eliminate vibration under heavy-duty operation for decades ahead. The reinforced bed structure and broadened cross-slide width increase the rigidity of heavy-cutting operation; The X/Z-axis guideway uses a combination of high-strength hard guide rail treatment (with hardness above 55 HRC) and precision machining to prevent creep and extend life. A nominal mass of 5000-11,500 kg and maximum payload of 5000 kg; thus providing reliable support in the process of shaping large workpieces without warping.

A spindle equipped with a high torque, 15-22kW high power variable-frequency motor; The spindle speed range is approximately 18-600 rpm (continuous speed adjustment through a 3-speed gearbox), suitable for different cutting conditions including rapid aluminium alloys processing and heavy duty applications such as stainless steel high-strength materials. The spindle hole diameter is within the range of 104－130 mm and can tolerate higher diameters; it uses a precision double row cylindrical roller bearing for assembly, which ensures that this kind of bearing has sufficient rigidity and low friction torque to ensure the accuracy spindle required by its application. The feed system uses high-precision preloaded ball screws directly connected to the motor, its positioning error of the x-axis and z-axis are ±0.025 mm; Its repeatability positioning accuracy meets at least ±0.01 mm standards; It can satisfy real-time performance with high-precision requirement of ultra-large components.

Has a high-performance CNC system (standard GSK980TDC, optionally Siemens, FANUC, or KND), supports automatic generation of programs, programme simulation and parameter memory function, as well as an easy-to-operate colour LCD screen. A four-station electrical tool post (optionally six) has a fast-tool-change function (within 1.5s), and an optional automatic bar feeder, hydraulic chucks, and robot-arm-lowering device are installed to achieve semi-manual operation or unmanned production.Built-in automatically chip transporter, force automatic-chip transport; each lubrication point with a specific fixed point quantification automatic oil injection system triggered alarm when encountered abnormal conditions or insufficient oil pressure. It improves production efficiency by 75% compared with semi-automatic heavy-duty lathes, suitable for large-batch production of ultra-large parts.

CK61100 has many kinds of Turning functions such as Cylindrical Turning, Conical Turning, Thread Turning (Metric/Inch/module/Diametric Pitch), Grooving, Facing, Boring, Drilling and Tapping; it can also perform complex curved surface Processing With Linear, Circular And Parabola Interpolation. The maximum swing of the bed is 1000mm; The range of turn radius is from 1500 to 12000mm (optional); It can process ultra-large parts, including long shafts, big discs, thick-wall pipes, heavy machine equipment, etc. Optional the whole enclosure shielding Design can protect the operator and prevent damage caused by fallen cutting or cooling liquid falls. Its modular Design and reasonable Structure have less failure point[s], The intelligent fault warning Function simplifies Maintenance, Extend s Service Life of Machine [at least] 15 Years.
