Commonly used manufacturing methods for large parts:

Casting and manufacturing of large parts

Casting is a common way to manufacture machining large parts. It is suitable for mass production of large parts with complex shapes, low dimensional accuracy requirements, use in extreme environments, or low material requirements.

The main advantage of casting is that it can produce parts that are full of texture, shape and appearance, while also being less expensive to produce. Common casting methods include sand casting, precision casting, die casting, etc. Among them, sand casting is suitable for large castings, which can produce nozzles, turbines, pipes and ductile iron with similar shapes and larger sizes; while precision casting is suitable for parts with high size requirements, such as precision instruments and aerospace engine parts.

Forging and manufacturing large parts

Forging is a method of processing metal materials into parts with similar shapes. Because forging can greatly improve the mechanical properties such as strength and toughness of materials, forging is a method often used when manufacturing high-strength parts such as aerospace engines, spacecraft components, rocket engines, and automobile engines.

Among them, shaft parts, pistons, half shafts, bolts, gears, impellers, etc. are all manufactured by forging.

Machining and manufacturing large parts

Machining refers to the use of mechanical processing methods to process unfinished large parts into final workpieces. It is suitable for mold machining large parts with complex dimensions,high processing accuracy requirements, high surface finish, solidity, and excellent extreme shape and regional wear resistance. Commonly used machining methods include CNC machining and general machining. If there is a huge demand for large parts, machining is used in conjunction with other methods rather than alone.

To sum up, there are diversified manufacturing methods for large parts. Casting, forging, and machining are commonly used manufacturing methods. Which method to choose usually depends on the shape and material of the part. Under normal circumstances, multiple manufacturing methods are considered comprehensively.

CNC machines, especially in the field of large parts machining, are impressive tools for manufacturing various products, but they have their own unique size limitations. Ordinary machine workshops or enthusiasts are unlikely to have a very large machine, as such equipment is often impractical.

How to machined large parts?

Specifically, CNC machining large parts is entirely achievable, but it requires more mechanical processing expertise and additional planning.

What is large CNC machining?

Large CNC machining is the process of manufacturing parts and components with larger dimensions and scales through CNC machining. Large CNC machining service centers can handle workpieces ranging in size from a few inches to several feet and are used in various industries, including aerospace, automotive, and construction.

Large CNC machine can provide the same level of accuracy and precision as small CNC machine tools, and can create complex geometric shapes and features on a larger scale. These machines usually require specialized equipment and expertise to operate

Certainly, CNC machining manufacturers provide several advantages when it comes to producing large parts. Here are some key advantages:

Precision and Accuracy

CNC machines are known for their high precision and accuracy. They can repeatedly produce large parts with tight tolerances, ensuring consistency and quality in each piece. This is crucial for industries where precision is a critical factor.

Complex Geometry

CNC machining allows for the production of large parts with intricate and complex geometries. The ability to program the machine to follow specific toolpaths enables the manufacture of parts that would be difficult or impossible to produce using conventional methods.

Efficiency and Productivity

CNC machining is highly automated, which leads to increased efficiency and productivity. Once the program is set up, the machine can run continuously, reducing downtime between production runs. This is especially beneficial for large-scale manufacturing.

Consistency and Reproducibility:

CNC machines can consistently produce large parts with the same level of precision and quality. This is crucial for industries that require identical components for assembly or replacement purposes.

Material Variety:

CNC machining can handle a wide range of materials, including metals, plastics, composites, and more. This versatility makes it suitable for manufacturing large parts for diverse industries such as aerospace, automotive, energy, and healthcare.

Reduced Human Error:

Automation in CNC machining minimizes the risk of human error during the manufacturing process. This leads to fewer mistakes and a higher likelihood of producing large parts according to the specified design.

Cost-Effectiveness:

While the initial setup and programming costs can be significant, CNC machining becomes cost-effective for large production runs. The automation reduces labor costs, and the efficiency of the process helps to optimize overall production costs.

Faster Turnaround Times:

CNC machining allows for faster production of large parts compared to traditional machining methods. The automated nature of CNC machines, combined with their high cutting speeds, results in quicker turnaround times.

Flexibility in Design Changes:

CNC programs can be easily adjusted to accommodate design changes. This flexibility is beneficial during the prototyping phase or when modifications are needed after the initial production run.

Quality Control and Inspection:

CNC machines often include built-in quality control features, and the process allows for in-process inspections. This ensures that large parts meet the required quality standards throughout the manufacturing process.

Waste Reduction:

CNC large parts machining is a subtractive manufacturing process, meaning material is removed to create the final part. This reduces material waste compared to some other manufacturing methods.
