Therefore, our company’s main focus and development direction are centered around CNC lathe.
2. Working Principles of CNC Lathes
2.1 Basic Principles of Computer Numerical Control (CNC) Technology
The CNC machining process involves designing the workpiece, developing machining strategies, writing machining programs, transferring programs to the CNC system, parsing and executing programs, machining the workpiece, and monitoring and adjusting the process. Firstly, a three-dimensional model of the workpiece is created using CAD software. Then, machining strategies are formulated to determine cutting paths and parameters. Next, machining programs are written using CAM software to translate the strategies into machine instructions. After transferring the program to the CNC system, the controller parses the instructions and controls the motion of the spindle, tool, and workpiece. Following the program instructions, the tool performs cutting operations on the workpiece, while the controller monitors the process in real-time and adjusts parameters to enhance machining quality.
2.2 Control System and Programming of CNC lathe
The control system of a CNC lathe consists of a controller, drivers, a programming interface, and program memory, among others. The controller receives and interprets the machining program instructions, while the drivers convert control signals into voltage or current signals to drive the motors for motion. The programming interface facilitates interaction between the operator and the system, and the program memory stores machining programs and related data. The programming process involves utilizing G-codes and M-codes to control motion and auxiliary functions, establishing coordinate systems to determine positions, and defining tool paths for machining operations. HAISHU offers CNC system assembly based on customer requirements, allowing customers to choose their preferred systems or configurations for the machine.
3. Key Components of CNC Lathes
3.1 Spindle and Sub-Spindle
The spindle and sub-spindle are common rotating axes in CNC lathe used to drive cutting tools and enable various machining operations. The spindle serves as the primary rotational axis, driving the main cutting tool for cutting operations, and typically possesses high speed and power. The sub-spindle, on the other hand, is an additional rotational axis that can operate independently. It is used for auxiliary cutting operations or to accomplish complex machining tasks, typically with lower power and speed. The simultaneous machining capability of the spindle and sub-spindle is suitable for processing long bar materials, part transfer, and intricate machining. Their collaborative operation enhances machining efficiency, productivity, and quality.
3.2 Machine Bed and Guideways
The machine bed and guideways are essential components of CNC machine tools. The machine bed forms the foundation structure of the machine tool, providing support and stability for various components. It needs to possess sufficient rigidity and stability. The guideways form the motion system of the machine tool, enabling precise positioning and alignment of the cutting tool and workpiece. Guideways can come in various forms, such as flat guideways, V-shaped guideways, rolling guideways, and linear guideways. The selection of guideways depends on the machine tool type, machining requirements, and budget considerations. Well-designed machine beds and guideways provide a stable machining platform, high-precision motion control, and superior machining results. HAISHU’s CNC lathe beds are manufactured using high-quality cast iron material for increased rigidity. They incorporate a combination of hardened guideways and linear guideways to enhance machining efficiency and precision.
3.3 Turret and Cutting Tools
The turret is a critical component of CNC lathe used for installing and controlling cutting tools. It typically consists of a tool holder and tool post, which secure and adjust the position and angle of the cutting tools. The turret can accommodate multiple tool posts, enabling quick tool changes during the machining process.
Cutting tools are essential tools used on CNC lathe for cutting and material removal. Common cutting tools include turning tools, milling cutters, drills, and more. The selection of cutting tools depends on the material being machined and the required machining operations. Cutting tools come in various shapes, sizes, and cutting edges to meet different machining requirements.
The selection and adjustment of the turret and cutting tools are crucial for achieving high machining quality and efficiency. In CNC lathe, operators can specify the tool selection, position, and cutting parameters in the programming interface based on the machining requirements. Turret adjustments can be made through the controller or manual operations to ensure proper installation and adjustment of the cutting tools. HAISHU provides detailed production plans and tool recommendations to simplify CNC lathe operation and workpiece machining for our customers. We offer various turret options, such as electric and hydraulic turrets. Additionally, there are multiple tool station options, including four-station, six-station, eight-station, and twelve-station.

3.4 Chuck and Workholding Devices
A chuck is a device used for holding workpieces and typically consists of adjustable jaws. They can be adjusted according to the shape and size of the workpiece to ensure its stable position during the machining process.
Workholding devices are used to secure workpieces and can be mechanical fixtures, pneumatic fixtures, hydraulic fixtures, or vacuum fixtures, among others. They secure the workpiece in the desired position by generating clamping forces, ensuring that the workpiece does not move or deform during machining.
Chucks and work-holding devices play a crucial role in CNC lathe by providing stable gripping force and position control, ensuring the accuracy and quality requirements of workpiece machining. The HAISHU brand has gained customer recognition by offering a variety of choices and solutions in the field of fixtures, allowing customers to achieve optimal workpiece holding solutions.

The CNC controller is the core component of a CNC lathe, responsible for receiving, interpreting, and executing machining program instructions, and controlling the machine’s motion and operations. It typically consists of an embedded computer or a dedicated CNC controller with high-speed computation and precise control capabilities.
Program storage is an essential part of the CNC control system, used to store and manage multiple machining programs and related data. It can take the form of internal memory, external storage devices, or cloud storage. Program storage allows operators to select and load appropriate machining programs as needed to meet the machining requirements of different workpieces.
By combining the CNC controller and program storage, operators can input machining commands through the programming interface and load the corresponding machining programs to achieve precise motion control and machining operations.
