How is CNC Machining Manufacturing Done?

CNC Machining is an automated process. But the automation needs to be configured by programmers first. There are some steps involved before one can proceed with machining the parts. I have briefly discussed the whole process below.

3D Model Creation

Model Making is the first thing to do for any manufacturing process. You can create a 3d model of your parts using CAD software. Keep in mind the machining process while designing your parts. Certain types of geometric features can complicate the process and increase your machining cost.

Design for Manufacturing

Any product design needs to be optimized to make it suitable for machining. Some features in the original design may be tweaked a bit to suit the machining process. It is known as design for manufacturing of parts.

Assessing the Required Machining Processes

Before machining a part, the part’s design is analyzed thoroughly to determine the required machining processes. Some parts need milling, some turning, and some may require multiple types of tools. It depends on the geometric features of a part.

Choosing an Efficient Machining Order

A successful machining operation is dependent on many factors. The proper order of the machining processes can be one of them. Always try to arrange it in such a way that the machining needs minimum tool change. It can reduce machining time.

Programing the Machine Codes

When you are done with all the pre-assessment tasks, it’s time for some coding. Convert your final design into a machine-readable code using CAM software. The code contains the tool change sequence, tool movement, rotation speed, etc. commands.

Let the CNC Machine do its Job

Once you have the code ready, your job is almost done. Place a solid block of your desired material in the CNC Machine. Input your codes in it. Then sit back and relax as the CNC machine completes the task with minimum human interference.

What are the Benefits of CNC Machining Manufacturing?

What are the Primary CNC Precision Machining processes Used by the Manufacturers?

There are different types of CNC machines available in the market with varied specifications. But the operations performed by them falls under some specific categories. The primary CNC machining process is discussed below.

Milling

Milling is the most common CNC machining process. It involves cutting the workpiece using rotating tools that can move in multiple directions and axes. The tools can have different diameters and shapes, each suitable for a specific geometry.

CNC Milling process is classified into peripheral and face milling. Peripheral milling is used for deep pockets, threads, etc. In contrast, face milling is used to introduce cavities with a flat bottom.

Turning

It is a convenient process for creating cylindrical parts with ease. The main difference between milling and turning is the rotating element. Unlike milling, the workpiece itself is rotated instead and moved against a tool in a linear direction. Turning is straightforward and faster compared to milling.

Drilling

Drilling is required for creating holes in a part. The tools used for drilling has a different structure than those used for milling and turning. The tools are called drill bits and have a helical shape around its periphery. Its shape allows the cut material to escape the hole. So, chips do not stack inside it.

Why do the CNC Machine’s Axis Matters for a Manufacturer?

The axis is a parameter for CNC machines. You will find CNC machines with a varying number of axes available in the market. They usually range from 2 to 7 axes. The axis gives a relative measurement of the capacity of a CNC machine. As the number of axis goes up, their capabilities also increase.

The 3-axis machines are one of the most used CNC machining tools in the world. The workpiece remains stationary, and the cutting tool works on the XYZ plane in 3-axis machines. It is one of the best tools to perform any job like drilling holes, milling slots, or cutting sharp edges on metal components.

The 4-axis tool is quite similar to the 3-axis tool. The only difference is there will be one or more additional rotation with A-axis or B-axis, where both axes will be around X plane. It allows Intermittent cutting, Continuous cutting, and Engraving curved surface.

Similarly, the 5-axis machine has two additional degrees of freedom. It has higher quality finishing and maintains intricate details. And the 7-axis CNC machines are considered the best out of all. It has the highest movement capabilities that enable the completion of more complex tasks.

So, as we can see, the axis is a major determinant of the capabilities of a CNC machine. So, it is very important for any manufacturer.

What is the Difference Between a CNC Machining and 3D Printing Manufacturer?

CNC machining is a subtractive manufacturing process that works by removing material from a solid block of material. 3D printing, on the other hand, is an Additive Manufacturing process that works by building the parts from scratch layer by layer.

Both CNC Machining and 3D printing can create plastic and metal parts. But to the cost of 3D printing metal is relatively high. Plastic is mainly used for 3D printing due to its material properties. Their low melting temperatures make them a suitable material for 3d printing.

In contrast, CNC machining is mostly preferred for the production of metal parts. Aluminum is the most used material in terms of using CNC machining. Apart from Aluminum, Stainless Steel, Brass, Zinc, and Magnesium Alloys also exhibit excellent machinability.

CNC machining is considered a more complex and time-consuming task to complete compared to 3D printing. But it is all worth it considering the higher degree of precision, and mechanical strength achievable with CNC precision-machined metal parts.

But as always, both of them have their pros and cons. The client may choose CNC machining or 3D printing, depending on their project requirement and financial constrictions.

What are the Common CNC Machines Available in China Machining Factories?

CNC machining is an automated process. There are different types of CNC machining tools being used in China manufacturing companies. Based on the machining operations performed, CNC machining tools can be classified into different types.

CNC milling machines are the most versatile CNC equipment capable of used to cutting random shapes, slots, pockets, holes, etc. In this case, the workpiece is stationary, and the machining tools are rotated against it to remove material.

CNC lathe is mainly used to do cutting on cylindrical objects. It works in the opposite manner of milling machines. The workpiece is rotated against a stationary cutting tool in this case. There are some other types of machining tools such as CNC plasma cutters, CNC grinders, CNC drilling machines and etc.

CNC Machines can also be thought of as a point to point systems. Here both tools and materials are placed on a fixed point until the process is done, and then it retracts automatically. The opposite is a contouring system, which is a process where the machining tool operates along a contour.

CNC machines can be classified based on their number of axes too. Usually, CNC machines range from 2 to 7 axes.

What are the Important Design Factors for CNC Machining Manufacturer?

There are quite a lot of design factors that can affect the CNC machining process. These factors are crucial to any CNC precision machining manufacturer in China. Some of the important design factors of CNC machining is explained below.

Holes: The size of holes should be kept within the limits of what an end mill tool can handle. Otherwise, a bigger hole may require using a drill bit. Machining with an end mill is preferable over drill bits due to their ability to machine more geometric features such as slots and deep pockets. It saves the tool change time.

Cavities: The designer should carefully choose the cavity depth. Machining deeper cavities with a standard end mill tool are more challenging and requires more time. So, that will increase the machining cost for you.

Internal edges: Always provide fillets to all sharp edges. Outer edges are manageable, but inner edges are very hard to machine without high-precision tools. Also, keep the radius of internal fillets within limits specified by your supplier.

Thin wall: Machining creates stress in your parts. Thinner walls are prone to fail under this stress. That’s why thin walls are machined with more time and consideration. The minimum wall thickness you can safely provide can vary depending on the material you are machining.

Small and Intricate Features: Some components may require tools with high accuracy due to their size and geometry. Smaller parts with intricate details should be avoided if possible. They require more sophisticated machining tools. Giving a significant rise to the machining cost.

What are the Most Used Aluminum Alloys in China CNC Machining Companies?

Aluminum alloys are one of the most popular material choices for CNC machining. Alloys are a composition of metal with multiple elements that increase the strength of the base metal. Pure aluminum is a relatively soft material for CNC machining, so alloys of aluminum are used instead.

Some of the common aluminum alloys used in the China manufacturing plants are discussed below.

Aluminum 6061

It is one of the best and most popular Aluminum alloys all over the world, including China. It has vast applications not limited to aircraft parts, boats or yacht.

Aluminum 6063

It is also another suitable metal to perform CNC machining. It is also easily weldable, but you should keep a certain heat treatment so that it does not lose its strength. It is good for frames of windows or doors.  Also, we can give shape to furniture or tubes from this Aluminum properties with the help of CNC machining.

Aluminum 5052

It is another good material property for CNC machining. It is used in many Chinese machining shops. It can be easily bent or punched. But it has got a higher resistivity to corrosion. It is suitable for aircrafts parts, home appliances, panels and etc.

There are few more Aluminum alloys like Aluminum 7075 and others available in China. Each of them has different properties and have a specific field of application.

What Should be the Qualities of a CNC Machining Company?

There are various qualities that a good CNC machining company should have. Machine capability and availability of various CNC machining tools are the most important thing for any CNC precision machining business in China.
