What Is CNC Precision Machining

Precision CNC machining is the most accurate, fastest, and efficient way to create machining parts which usually is hard plastic and metal materials.

Precision CNC machining is a process that machines use computer-aided manufacturing (CAM) or computer-aided design (CAD) to create high complexity and tight tolerance parts which raning from +/- 0.001mm to +/- 0.02mm. These technologies are state-of-the-art that can make the parts are meet design specific and exact dimensions on the CAD drawings.

These precision machines incluing of CNC Milling, CNC turning, CNC lathe, CNC router, WEDM, plus EDM and Grinding to cut or drill metal work-pieces with extreme accuracy to final precision desired parts. The process has been around for decades but it has only been in the past 10 years that it has become more popular because of the accuracy and precision of modern machines, and it is especially popular for automotive and aerospace industrials.

Types of Precision Machining Equipments

Precision CNC machines are a type of machine that is used in manufacturing to create precise parts and products. There are 3 main types of precision CNC machines, which are the following:

(1). 3 axis cnc machine

A 3-axis CNC mill is a machine tool that can cut, form and shape a material. A 3-axis CNC milling machine is designed to perform the operations of machining, milling and drilling. It works by moving the cutting tool in all three axes (X, Y, Z). The movement in each axis is controlled by servo motors or stepper motors.

(2). 4 axis cnc machine

A 4 axis CNC milling machine is a device that can be programmed to perform a wide range of operations, including cutting, drilling, and engraving. The machine has four axes of movement: x-axis, y-axis, z-axis and rotary axis.

A 4 axis CNC milling machine is generally used in manufacturing. It can be used for the machining of parts made from various materials such as steel or aluminum.

(3). 5 axis cnc machine

A 5 axis CNC machine is a machine that can move in 5 different axes. This means that it has the ability to move in any direction, making it much more versatile than a 3-axis and 4-axis machine.

A 5-axis machine is a milling machine that can move the cutting head in any of the three rotational axes, and also along two linear axes. The tool head moves on 2 or 3 parallel rails, each with an axis of rotation perpendicular to the other two.

How can I improve my CNC accuracy?

Using imported multi-axis milling machines from the United States and Japan, as well as the top brand from China, we can guarantee CNC milling parts that are within the tolerance of +/-0.05mm, while also keeping critical dimensions under +/- 0.005mm.

Our team also has extensive experience creating precision parts for some of the most demanding industries in the world, including aerospace and medicine.

The 5-axis CNC milling machines come with an on-site inspection system that allows us to monitor the actual dimensions of a part during the milling process. The computer is able to automatically adjust the program and parameters to ensure that the parts are manufactured correctly.


Unlike CNC milling, the CNC turning process uses a single-point cutting tool to create precise cylindrical cuts into a rotating material. This automated technique provides great accuracy and a high degree of repeatability and is ideally suited for manufacturing circular or tubular shapes. The CNC turning lathe secures and rotates the material as its machined at high speeds.

Our expert technicians are able to achieve incredible accuracy when producing components because of the professional-grade CNC turning machines that we have available.

While CNC milling is ideal for short-run volumes of prototypes and parts that are below 2.5” OD, CNC turning machines are better-suited for short-run volumes of larger parts above that threshold.

Common applications for CNC turning include functional prototypes, spacers, manifolds, fittings, shafts, and bushings.

precision EDM WIRE EDM

Precision EDM Wire EDM

3Q Machining also provides industrial-grade wire electrical discharge machining (EDM) to our global customer base. Wire EDM is used to cut a variety of electrically conductive materials.

The process involves an electrically-charged EDM wire that is positioned between two mechanical guides, forming an electrode while the material that is being cut generates the second electrode. This creates an electrical discharge between the wire and workpiece, effectively cutting away from the material.

Since the wire doesn’t actually make physical contact with the material, EDM machining can be used to produce parts and prototypes that are extremely small and delicate. This method is able to cut through metal materials that are difficult to handle with other methods, including steel, bronze, copper, and titanium, to name a few.

It’s commonly used to produce circuit boards and essential equipment for the automotive, aerospace, and consumer electronics industries.


3Q Machining’s prototyping facility is also equipped with high-precision grinding machines. This process is ideal for manufacturing metal parts and prototypes with very tight tolerances. Grinding uses a spinning wheel composed of bonded abrasive particles to remove material from a workpiece until it meets the desired shape and specification.

Like Wire EDM, precision grinding is best suited for manufacturing tiny metal parts and larger parts that require tighter tolerances, including components for medical devices, aerospace parts, scientific instruments, and more.

3Q Machining’s expert staff will help you decide on the optimal grinding method and tool for your part, taking all specifications and requirements into account.

Overviews of The Best Precision CNC Machining

Precision machining is an essential manufacturing process that enables companies to produce the most delicate parts with the tightest tolerances imaginable. Here are just some of its main advantages over alternative approaches:

1. High Precision:
As the name implies, precision molding offers unparalleled accuracy, producing consistent quality with every part that is produced.

2. Minimal Errors:
Because precision machining uses CNC technology, it is largely automated and reduces the probability of error to a minimum.

3. Efficiency:
Because of the automated nature of the process, precision CNC machining can produce parts very efficiently and with minimal workforce intervention.

4. Less Waste:
Precision machining produces minimal waste, allowing to save on materials and maintain environmentally-friendly manufacturing practices.

5. Cost-Effective:
The high-tech nature of the process also means that there’s less waste, less labor, and a low chance of error, which makes it one of the more cost-effective manufacturing methods.

When to choose precision machining?

When designing parts, some engineers suggest very tight tolerances, far more than are actually needed. That’s not an ideal approach. If +/-0.05mm works, opting for +/-0.01mm tolerance will increase the manufacturing cost many times. However, when you do need tolerances as tight as 0.01mm, then you can’t beat the accuracy and consistency offered by precision machining.

What materials can be used with precision machining?

There’s a wide range of materials that can be used in precision machining – you can use aluminum, brass, copper, steel, titanium, as well as rigid plastics like PPS, PEEK. Reach out to learn more about the types of materials that are available when using precision machining technology.

How can 3Q Machining guarantee tight tolerances?

We use high-quality machines for precision CNC milling & turning, precision EDM, precision grinding, and a range of other tools in house, using AC to stabilize the workshop temperature. That, combined with the experience and qualifications of our engineers, as well as rigorous inspection of machines and processes, ensures consistent quality even in the most demanding scenarios.

How CNC machines can be used for precision manufacturing?

Precision CNC machining is a process that can be used to produce components with high accuracy and tight tolerance. It is an automated process that uses computer-aided design (CAD) and computer-aided manufacturing (CAM) to create a digital model of the component to be produced.

The CNC machines then uses this digital model to produce the component by cutting away material from the surface of a piece of stock material, such as metal or plastic. The machine can also drill holes, cut slots, and do other tasks in order to produce complex shapes.

Precise CNC machining

Precision machining is a manufacturing process that involves the use of high-precision machinery, such as 3-axis, 4-axis, 5-axis CNC machines, cnc lathe, cnc router, grinding and EDM machines to produce parts with high accuracy. It has been widely adopted in various industries for its cost effectiveness and precision.

Precision machining process that machine raw material from a work-piece, while holding tight tolerance and high requirement finishes, to create a precise product. it means machine work-pieces of material into any complex and precise machined parts, so that they can meet the high precesion requirement of drawing specifications.

Why cnc precision machining is popular in manufacturing?

There are many reasons why precise machining is used in manufacturing. One of the main reasons is that it can produce parts that are more accurate than any other manufacturing processes. It also has the ability to create complex shapes with ease and speed.

  • 1. Accuracy: The accuracy of the machine depends on the precision of the cutting tool, which is controlled by the computer program.
  • 2. Speed: A CNC machine can produce parts much faster than other manufacturing processes such as casting or forging because it does not need to wait for the material to cool before removing it from the workpiece.
  • 3. Complexity: Complex shapes can be created with a high degree of precision due to the high degree of control over motion and speed in modern machines, compared to traditional hand methods like carving or turning on a lathe.

The difference between CNC machining and precision machining is that CNC machining is a process where a computer controls the movement of the machine, while precision machining is including of cnc machining and manual machining that these machining process can produce high precision machined parts to meet drawing specifications accurately.

What is the difference between CNC machining and precision machining?

Both CNC and precision machines are used to produce parts for different industries. Precision machines are often used in industries such as aerospace, military, and medical industries, while CNC machines are often used in automotive, manufacturing, and other mechanical industries.

Precision is not a measure of how close a machined surface is to the desired finish. It is the degree of variation from one part to another.

Tolerance is the maximum allowable deviation from the nominal size or dimension.

The precision of CNC machining depends on how well the machine was set up and how well it was maintained. The tolerance, on the other hand, depends on what kind of material you are cutting and what kind of tool you are using.

How precise can a CNC machine cut for?

So when you wondering how precise can a CNC machine cut for? The answer is a CNC machine usually can cut precise part a tolerance of +/-0.02mm for metal and hard plastic materials, but now, as the cnc machines become more and more precise, the latest cnc machines can make highest precision with very tight tolerances at +/- 0.001mm precision for metal machining parts.

CNC machining is a process of shaping metal or other material using computer-controlled cutting tools. CNC machining is often used to produce complex shapes that are difficult to make with traditional manufacturing methods.

The profitability of cnc machining business varies based on the type of industry and the location. The more competitive an industry, the harder it will be to maintain profitability.

CNC machining business is profitable

In general, CNC machining business is profitable. The cost of the machine, materials, and other machining costs are all factors to consider when determining the profitability of CNC machining.

The CNC machining business profit is sometimes calculated by subtracting out the cost of the machine and materials from the gross revenue generated by a job. This gives you an idea of how much money you’re making after paying for your materials and equipment.

People might be wondering how much profit can a CNC Machining Business make? Most of CNC Machining businesses have net profit margin from 10 to 20 percent for every order, sometimes the profit margin can be 50% more due to the machined parts require more advance machine and high technique requirement. For a cnc machining shop that have annual turnover $2,000,000, that has business profit of $200,000 to $400,000 for the business owner.

Machining is a process that can be divided into two parts: cutting and forming. The cost of machining depends on the material and the complexity of the part.

Cutting: Cutting is done by removing material from a workpiece with a rotary tool, such as a drill or end mill, or with an abrasive cutter such as a saw blade. The cost of cutting depends on the type of cutter used, the diameter of cut, and how much material needs to be removed.

Forming: Forming is done by deforming metal to create new shapes. This includes processes like drawing, rolling, bending and coining. The cost of forming depends on what type of forming process is being used, how much metal needs to be deformed, and how difficult it will be to forming.

How much does machining cost?

How much does machining cost? In general, the machining cost per hour at a CNC Machining Shop usually cost at around $30 per hour, CNC turning and CNC router is lower price at around $25 per hour, while the multi-axis “3-axis, 4-axis, 5-axis” CNC Machining cost around $60 to $100 or higher based on the complexity of machined parts or high precision machining like Aerospace CNC Machining.
