    Appearance and Features

    ✓
    The machine head box and the bed, tailstock, pallet and other joint surfaces are manually scraped and polished, and the whole machine is tested which effectively guarantees the positioning accuracy of the Z axis and X axis, repeat positioning accuracy, reverse clearance and stability of the machine tool.
    ✓
    The machine tool adopts high-strength cast iron and hard guide rails with wear resistance and stability.
    ✓
    The machine tool spindle adopts high properties bearings, and the machine tool gears adopt precision grinding, which effectively improves the gear hardness and reduces the machine tool noise.
    ✓
    The machine tool, Z-axis ball screw, and X-axis ball screw adopts a tensile structure, which improves the accuracy of the outer circle and inner hole size of the workpiece.

    Configuration Introduction

    Heavy Duty CNC (2)

    1. CNC Control System

    The GSK980TB3i bus system is a high-performance CNC system developed by Guangzhou CNC Equipment Co., Ltd. The system adopts advanced control algorithms and high-speed processors to achieve high-speed and high-precision processing control. It supports multi-axis linkage control and can meet the processing requirements of complex parts. It has rich functions, such as tool radius compensation, tool length compensation, backlash compensation, pitch error compensation, etc. It also supports macro programming, graphic simulation, online processing and other functions, which are convenient for users to program and operate.

    2. Manual chuck and tailstock

    The standard configuration use manual chuck and tailstock that have the characteristics of simple structure, high flexibility, large clamping force, high precision, low cost, wide application range and easy operation.

    The manual tailstock can be flexibly adjusted according to the processing needs. By rotating the handle, the tailstock sleeve can be moved forward and backward in the tailstock body to adjust the distance between the center and the workpiece. In addition, the tailstock can also move left and right on the lathe bed to accommodate workpieces of different lengths.

    3. 4-station electric tool post

    The 4-station electric tool holder can install 4 tools. Through electric control, the tools can be automatically changed and the tool change speed is fast, which improves the processing efficiency.

    Frequently Asked Questions

    What are the main capacity differences between the CK6140, CK6150, and CK6180 models?
    The primary differences lie in their maximum turning diameters over the bed: CK6140 is 400mm, CK6150 is 500mm, and CK6180 is 800mm. Additionally, their spindle motor power ratings scale from 5.5KW to 7.5KW and 11KW respectively, to accommodate different machining loads.
    What CNC system controls these lathes?
    These machines utilize the GSK980TB3i bus system, a high-performance CNC control system developed by Guangzhou CNC Equipment Co., Ltd. It features advanced control algorithms, supports multi-axis linkage, and includes built-in functions like tool radius compensation and backlash compensation.
    What type of manual chuck is configured with each lathe model?
    The CK6140 and CK6150 models are standardly configured with a three-claw manual chuck, whereas the heavy-duty CK6180 model is equipped with a four-claw manual chuck to handle larger and more complex workpieces.
    What is the positioning and machining accuracy of these CNC lathes?
    All models (CK6140, CK6150, and CK6180) deliver high precision performance with a repeat positioning accuracy of 0.01mm, machining accuracy of 0.01mm, and a spindle beat of 0.01mm.
    How does the 4-station electric tool post benefit the manufacturing process?
    The 4-station electric tool holder allows for the simultaneous installation of 4 tools. Controlled electrically, it facilitates quick and automatic tool changes, significantly reducing non-productive time and boosting overall production efficiency.
