CNC milling machines and CNC lathes are two common types of CNC machine tools, and they have some differences in terms of machining methods and principles:

1. Machining Methods:

   - CNC milling machines are mainly used for cutting and carving operations on the surface of workpieces. Material removal is achieved by rotating the cutting tool, and it can perform machining on flat surfaces, curves, and complex shapes.

   - CNC lathes are primarily used for the machining of rotating workpieces. The workpiece is fixed and rotated while the cutting tool, mounted on a turret, performs cutting operations. It can handle outer diameters, inner diameters, threads, and end surfaces.

2. Working Principles:

   - In CNC milling machines, the workpiece is fixed on the worktable, and the cutting tool moves in different axes to perform cutting operations. Typically, it has multiple axes (such as X, Y, Z) for movements, allowing for multi-directional cutting and 3D machining.

   - In CNC lathes, the workpiece rotates on the main spindle while the cutting tool remains fixed on the tool turret. The cutting tool can move in horizontal and vertical directions to achieve various types of cutting operations.

3. Suitable Workpiece Shapes:

   - CNC milling machines are suitable for machining complex shapes such as flat surfaces, curves, cams, gears, etc. They are ideal for workpieces that require multi-axis movement and 3D machining.

   - CNC lathes are suitable for machining long bar-shaped or cylindrical workpieces. They can handle outer diameters, inner diameters, end surfaces, and threading operations.

4. Application Fields:

   - CNC milling machines are widely used in mold manufacturing, aerospace, automotive components, electronic devices, and other industries.

   - CNC lathes are widely used in automotive components, pipe fittings, shaft parts, and threading operations.

Although CNC milling machines and CNC lathes have different machining methods and application ranges, they are both CNC machine tools capable of precise machining operations through pre-programmed instructions. They improve production efficiency and machining accuracy.

CNC machining can achieve different tolerance requirements depending on the equipment, materials, and processes used during the machining process. Here are some common tolerance grades and their corresponding precision ranges:

1. General Tolerance: In general engineering applications, the common tolerance grade is the "m" grade according to ISO 2768-1. General tolerance requirements are relatively loose and are typically suitable for general mechanical part manufacturing, with tolerance ranges reaching a few millimeters or larger.

2. Medium Tolerance: In applications that require higher precision, such as precision mechanical part manufacturing, the common tolerance grade is the "f" grade according to ISO 2768-1. Medium tolerance requirements are relatively strict, with tolerance ranges typically falling within tens to hundreds of micrometers.

3. High Precision Tolerance: For applications that demand extremely high precision, such as aerospace and optical instruments, more stringent tolerance requirements are needed. The tolerance grade is usually the "e" grade or higher according to ISO 2768-1. High precision tolerances can be achieved within ranges of tens to a few micrometers.

It's important to note that tolerance requirements may vary based on different machining characteristics, material properties, and product designs. Additionally, achieving high-precision machining often requires advanced and precise equipment, as well as strict quality control and process control.

In practical applications, ensuring the desired tolerances are met depends on selecting appropriate machining equipment, and suitable process parameters, and implementing effective quality inspection and control. Therefore, before undertaking CNC machining, it is recommended to discuss and confirm the tolerance requirements with the experts at Flourish Legend to make appropriate decisions during the machining process.

CNC milling is a machining process where the cutting tool rotates and removes material from the workpiece under the control of a computer numerical control (CNC) system. Here is a translation of the basic working process of CNC milling:

1. CAD Model Design: Firstly, a three-dimensional model of the workpiece is created or imported using computer-aided design (CAD) software. This model describes the shape, dimensions, and machining requirements of the workpiece.

2. CAM Program Generation: Based on the CAD model, a machining program is written using computer-aided manufacturing (CAM) software. This program guides the CNC system with information such as the cutting path, tool selection, cutting parameters, and more.

3. Workpiece and Tool Setup: The workpiece is mounted on the milling machine's worktable, and appropriate cutting tools are selected. The choice of cutting tools depends on the specific machining requirements, such as different types of milling cutters, drills, boring tools, etc.

4. Establish Workpiece Coordinate System: Using the machining program and the geometric features of the workpiece, a coordinate system is established within the CNC system. This coordinate system determines the position and motion trajectory of the tool on the workpiece.

5. Debugging and Preheating: Before actual machining, the CNC system and tools often undergo debugging and preheating. The debugging process validates the machining program and tool paths and performs necessary calibrations and adjustments.

6. Initiate Machining: Once the debugging and preheating are completed, the operator starts the CNC system to begin the machining process. The CNC system controls the milling cutter to cut the workpiece based on the defined paths and parameters in the machining program.

7. Real-time Monitoring: During the machining process, the CNC system monitors key parameters such as tool position, cutting force, cutting speed, etc., in real-time. Adjustments and corrections are made as necessary to ensure machining accuracy and stability.

8. Completion of Machining: Once the machining is finished, the cutting tool automatically stops, and the machined part can be removed from the workpiece.

CNC milling achieves high precision and efficiency through precise control of cutting paths. This machining method is widely used in various industries, including aerospace, automotive manufacturing, mold making, and more.
