铝铸件加工和CNC加工如何选择?

Aluminum casting machining and CNC machining

Aluminum casting machining and 数控加工 are both common manufacturing methods. 它们在不同的环境下有各自的优点和缺点. 下面新易科技从材料特性等各个维度进行了比较, 成本, 生产提前期, 准确性, ETC. 并给出最终建议.

1. Material properties

Aluminum alloy casting processing: aluminum alloy casting can produce complex shapes of parts, but the casting material properties are limited. Aluminum alloys have good fluidity and are suitable for casting molding.
数控加工: CNC machining can be applied to a wide range of materials, including aluminum alloys. It is suitable for producing high-strength, high-precision parts.

2. Cost

Aluminum Casting Processing: Casting molds are expensive to make, but the cost per piece is lower in high volume production.
数控加工: CNC machining is relatively inexpensive initially, but can become more expensive in high volume production.

3. Production cycle

Aluminum Casting Processing: Casting molds take time to make, but once made, large quantities of parts can be produced quickly.
数控加工: CNC machining can be started quickly and is suitable for small batch production, but may take more time for mass production

4. Accuracy and surface quality

Aluminum Casting Machining: Casting usually produces a rougher surface that requires secondary machining to improve accuracy and surface quality.
数控加工: CNC machining provides higher accuracy and surface quality and reduces the need for secondary machining.

5. 适用场景

Aluminum alloy casting processing: applicable to large quantities, the shape of the more complex parts, such as automotive parts.
数控加工: suitable for small quantities of parts requiring high precision, such as aerospace parts.

Suggestion

For large quantities of parts with more complex shapes, especially if the initial investment is large and the production cycle is long, aluminum alloy casting machining is a cost-effective choice.
For small quantities, parts requiring higher precision, especially when flexible production is required, CNC machining is more suitable.
In practical application, sometimes you can also consider combining the two processes, according to the specific circumstances of the flexible choice, in order to maximize the product to meet the requirements.
