The Power of CNC Milling: Unlocking the Possibilities of Mechanical Treatment
In the world of mechanical treatment, CNC milling is one of the most widely used and versatile techniques. With its ability to process a variety of materials and create complex shapes, CNC milling has become an essential tool for manufacturers and engineers. In this blog post, we will explore the different types of parts that can be machined using CNC milling and the various techniques used to achieve optimal results.
Flat Parts: The Building Blocks of CNC Milling
One of the most common applications of CNC milling is processing flat parts. These parts are characterized by a surface that is parallel or perpendicular to the horizontal plane, with an angle between the treatment surface and the horizontal plane. Within this category, there are two subcategories: curved outline surfaces and inclined surfaces.
Curved Outline Surfaces: The Power of Angles
Curved outline surfaces are a staple of CNC milling. In this type of surface, the curved outline is perpendicular to the horizontal plane, making it an ideal candidate for milling. For parts with a boss at an angle to the horizontal plane, a special angle forming knife can be used to treat the surface.
Inclined Surfaces: The Art of Leveling
For inclined surfaces, the part can be leveled using a tilted plate, allowing for a smooth and precise machining process. This technique is particularly useful for parts that are not large enough to be processed using other methods.
Direct Pattern Surface Parts: The Beauty of Straight Lines
Direct pattern surface parts are another popular application of CNC milling. These parts are characterized by their curved shape, which is generated by moving straight lines according to specific rules. With the use of a CNC grinder with four or five coordinates, these parts can be machined with precision and accuracy. In fact, it is possible to treat these parts using a CNC milling machine with three coordinates, albeit with slightly reduced precision.
Three-Dimensional Curved Parts: Theinnacle of CNC Milling
The crème de la crème of CNC milling is the treatment of three-dimensional curved parts. These parts have a surface that is a space curve, making it impossible to distribute it in a plane. To machine these complex shapes, CNC grinding with three coordinates is typically used, accompanied by two treatment methods: cutting and treatment, and liaison treatment with three contact details.
Cutting and Treatment: The Dual Approach
In the cutting and treatment method, a CNC grinder with three coordinates is used for semi-coordinated control treatment with two axes. This approach involves linear interpolation along the plane curve, with the ball head striking the workpiece at a specific angle. The distance between two adjacent curves must be selected according to the surface roughness requirements and the radius of the fraying of the ball head.
Liaison Treatment with Three Contact Details: The Cutting Edge
The liaison treatment with three contact details involves using a CNC milling machine with three coordinates to perform linear interpolation of the space. This technique is particularly useful for complex shapes like hemispherical or spherical shapes, which can be treated with the three-coordinate system.
In conclusion, CNC milling is an incredibly versatile and powerful technique for mechanical treatment. With its ability to process a wide range of parts, from flat to three-dimensional curved, CNC milling has become an essential tool for manufacturers and engineers. By understanding the different types of parts that can be machined, as well as the various techniques used to achieve optimal results, we can unlock the full potential of CNC milling and take our manufacturing processes to the next level.
