Aluminum CNC Machining Parts: How to Ensure Accuracy And Stability


CNC, or computer numerical control, is an indispensable tool in modern manufacturing. The use of CNC technology, can achieve high precision machining parts, greatly improve the production efficiency and product quality, among them, aluminum CNC machining parts is the most widely used one

The characteristics of aluminum make it a very suitable material for CNC machining, and the process of aluminum CNC machining is very simple. It uses a computer controlled rotary tool to cut excess material to obtain the desired shape and size. But even in such a basic process, there are many factors that will affect the accuracy and stability of the workpiece, Longsheng technology website this blog will discuss how to ensure the accuracy and stability of aluminum CNC parts from the design, material selection, process flow and other aspects, so that your CNC machining more quickly and accurately

An effective method of ensuring accurate and stable manufacturing

Precision and stability are two factors that must be considered in the manufacturing of aluminum CNC machining parts. The following Longsheng technology will tell from four aspects to ensure that aluminum cnc machining parts accurate and stable manufacturing methods

Design aspect

Design is one of the most important factors affecting the accuracy and stability of aluminum CNC parts. In the design process, the following points need to be considered:

Virtual simulation

Before CNC machining, we can first carry out machining simulation through virtual simulation, so as to find potential problems and make improvements to avoid errors in the process of machining.

The design should be fully in accordance with the CAD drawings

CAD drawings can be adjusted during the design process according to different tasks and different needs, such as size, shape and Angle, but we must ensure that the final CAD drawings match the real thing exactly. In this way, we can use CNC machine to process more easily, to ensure the precision and accuracy of parts.

Consider the physical properties of the aluminum material

During the design process, different properties of materials, such as hardness, density and thermal conductivity, need to be considered. Aluminum has light weight, high strength and good mechanical properties. At the same time, its density is lower than that of steel, which makes aluminum products have higher specific strength and specific stiffness. In addition, aluminum has high corrosion resistance and thermal conductivity, which makes it widely used in aerospace, automobile manufacturing, medical instruments and other fields.

Reduce thermal deformation

In the process of machining high precision aluminum CNC parts, it is necessary to reduce thermal deformation effectively. This can be done by reducing the cutting amount of the tool, or by using low speed and high precision cutting during machining.

Material selection

Aluminum alloy is a commonly used material, because of its light weight, high strength, good corrosion resistance and other characteristics, is widely used in aviation, automobile, equipment, construction, decoration and other fields. When choosing materials, you need to consider the following:

Hard material

The hardness of the aluminum material can be selected to make the parts more durable. By choosing high hardness aluminum products, we can increase the durability and reliability of parts.

Prestressed aluminum sheet

When machining high-precision aluminum CNC parts, the selection of prestressed aluminum plate can effectively reduce deformation, so as to improve the accuracy and stability of the parts.

High temperature resistant material

In high temperature environments, design and material selection need to consider application requirements beyond normal operating conditions. Aluminum products can be selected by high temperature resistant aluminum alloy material, to achieve high strength, corrosion resistance and high temperature resistance.

Light weight material

The light weight of aluminum reduces the overall weight of the part and allows for better consideration of the installation and handling characteristics of the part during the design process. Therefore, in the need for lightweight design of various industries, aluminum products are the better choice.

Technical process aspect

Aluminum CNC machining parts need to follow the appropriate process flow to ensure high quality and precision parts production. Here are a few steps to look for:

Before CNC processing, materials need to be pre-treated, such as annealing, pickling and so on. This can avoid defects such as spots, oxidation and bubbles on the surface of the material.

Select the correct CNC machine tool

Selecting the right CNC machine tool is very important for parts production. A good CNC machine can ensure the precision and accuracy of the parts. In addition, aluminum materials and different CAD drawings need to be equipped with different CNC machine tools.

Choose the right tool

It is very important to choose the right cutting tool for aluminum CNC machining. If the use of tools not suitable for aluminum material machining, it may lead to a loss of accuracy and quality. As a result, manufacturers need to select tools specifically designed to process aluminum materials. These tools usually have the following characteristics:

• High speed drill bits: High speed drill bits are mainly used for drilling aluminum. Using a high speed drill ensures the accuracy and quality of the hole.

• Precision milling cutters: Precision milling cutters are commonly used to process aluminum alloy materials. They have high-speed cutting capability and high precision to ensure surface quality and accuracy of parts.

• Special cutting fluids: The use of special cutting fluids removes heat from the cutting process, thereby reducing the temperature of the cutting process. This helps ensure stability and accuracy during processing.

Properly handle the work surface

Good surface treatment can improve the surface quality and precision of aluminum CNC machining parts. Properly treated surfaces can eliminate possible scratches and other blemishes. Surface treatment methods include grinding, polishing and spraying.

Conduct quality inspection

Finally, after the parts are finished, you need to do quality testing. Using computer numerical control (CNC) machining technology can ensure that your parts are accurate to a few decimal places, but you will need to perform further testing to ensure that the numbers are accurate

CNC machining manufacturer technical aspects

For some fields, such as medical devices, the company system must meet certain technical requirements. This includes:

Select the right CNC machining center

In CNC processing of aluminum materials, the first need to choose the correct CNC machining center. The task is not so easy. Generally speaking, CNC machining centers suitable for processing aluminum parts should have the following characteristics:

• High speed and high precision spindle: A good CNC machining center should have high speed and high precision spindle, which can ensure the accuracy and quality of aluminum materials when being processed.

• Large-scale processing capacity: When CNC processes aluminum parts, it requires large-scale processing capacity, so as to ensure that the aluminum parts produced can meet customer requirements.

• The latest CNC control system: The latest CNC control system can ensure the accuracy and stability of the machining process. It ensures that the position and trajectory of the aluminum material can be strictly controlled throughout the machining process, thus ensuring the accuracy and stability of the parts.

The company is based on ISO 9001 certification

Every aspect of the company is in full compliance with ISO 9001 certification requirements, including product design, production, installation and commissioning, and other quality management requirements. This is a key measure to ensure the quality and stability of parts.

It is capable of mass production

Aluminum CNC machined parts need to ensure consistent quality and quantity during production, so manufacturers with mass production capabilities can better respond to the needs and sizes of different industries.
