What Is CNC Precision Machining?

Before talking about CNC precision machining, let’s first know what exactly CNC means. The abbreviation of Computer Numerical Control is CNC. You can compile CNC codes on a computer and translate them to CNC machines. So, when CNC programs control a device, the machining process is usually called CNC machining.
Since CNC precision machining works following the CNC codes, it reduces the use of manual operations. Besides, CNC precision machining offers more benefits, and we’ll briefly discuss that in the next section. However, CNC precision machining is extremely popular in many industries. You may find this technology in automotive, construction, industrial, and many more industries. In these industries, they require high-precision metal parts. A tiny deviation may alter the product performance. To mitigate such problems, they require CNC precision machining in their parts manufacturing process.

What Is The CNC Precision Machining Process?

We can make various precision machining parts easily & quickly using CNC machines. The process is not tricky. All you need is to understand the correct sequence of CNC codes and tricks for operating the machine. You should also focus on the selection of the right tools. However, a typical CNC precision machining process involves four primary steps. Let’s find out more.

Creating Design

Preparing the design is the first step of the process. Remember, a well-prepared design ensures a perfect sequence of machine codes. Ultimately, it contributes to the overall quality of precision machining parts. In this case, you can use various CAD software. Next, import the CAD file into CAM software. What is CAM? It is called Computer Aided Manufacturing Software. It can give you perfect tool paths & machining instructions.

Preparation & Machine Setup

At this moment, prepare the material and machine for the precision machining process. While preparing material, focus on sizing. Use the machine clamps or fixture to secure it within the CNC machine. Now, set up the machine using an appropriate cutting tool. You may require multiple cutting tools. Note that the types of cutting tools depend on the type of CNC machining process.

Finally, this step may require additional finishing tasks. For example, cleaning and surface finishing are noteworthy. The type of additional machining depends on the specific requirements of your project.

What Are The Advantages Of CNC Precision Machining?

Speaking of advantages, CNC precision machining is extremely popular in part manufacturing. Everything that precision manufacturing requires can be fulfilled by this technology. Let’s explore more.

1: High Precision: It’s the most crucial benefit. CNC machining evolved to make precision products with shorter manufacturing times. So, without a doubt, CNC machines provide incredible precision. The result you get is tight tolerances & exact specifications.

2: Complex geometries: Before, traditional methods took a long time to make relatively complex machined parts. After CNC machining appears, you make it in a minute. This CNC precision machining part is so famous for its complex geometries.

3: No human error: Human makes a mistake, but the machine doesn’t. We all are familiar with this term. When you insert your CNC code into the machine, the device just follows your command. Therefore, CNC machining ensures no human error. Note that a single coding sequence can make an array of CNC machining parts.

4: Prototyping & customization: Here comes another crucial advantage of using CNC machines. You know that making custom parts using dies & molds can be expensive. So here, these devices play an important role. It produces prototypes & custom parts cost-effectively.

5: Safe: Indeed, CNC machining is safe for humans. Every CNC machine comes with protective doors. So that during operation, the residue doesn’t come outside. As a result, it reduces injuries.

6: Lower-cost: Overall, CNC machining is a cost-effective process. Let’s consider other benefits one more time. This machining process is fast and can create complex geometries with no error. So, compared to other part manufacturing processes, CNC machining is a cost-effective solution.

Materials Used For CNC Precision Machining & Popular CNC Machining Parts

Considering all the benefits we discussed above, we can imagine a lot of products now. Also, you can work with various materials. For example, if you consider metal, note aluminum, steel, brass, copper, titanium, bronze, and nickel alloys.
There are hundreds & thousands of metallic parts you can make from CNC machines. Precision parts are prevalent in the aerospace, automotive and medical industries. Other types may include fasteners, custom brackets, shafts & spindles and valves & fittings. Besides, bushings & bearings, connectors & couplings and custom prototypes are also noteworthy.

Different Types Of CNC Precision Machining Parts

After discussing the materials & products, we can realize the demands of CNC machining parts. The products discussed in the table can not be manufactured through a single CNC machining process. Therefore, machining parts manufacturers employ different types of CNC machining types. To understand different types, generally, we can differentiate them through different dimensions. Is it a horizontal machine or a vertical? Does it work in a 2-axis, 3-axis, or multiple-axis?

Let’s talk about a 3-axis CNC machine. This type of machine can work in three dimensions (X, Y, Z). On the other hand, 5-axle CNC machines offer machining in multiple coordinate systems. These types of machinery are highly suitable for making complex geometry CNC parts. What about the lathe machine? It’s a 2-axis CNC machine. It can only work on the X-axis and Z-axis.

CNC Turning

CNC turning is also famous as CNC lathing. In a typical CNC lathe machine, you can find a rotary attachment and a cutting tool changer. Normally, the rotary attachment secures the raw material and rotates at certain speeds. On the other hand, the cutting tool change moves along the Z-axis. This movement depends on the inserted CNC programming or coding sequences.
CNC turning also has different types. Among all these types, two-axis, multi-spindle, swiss type, and horizontal and vertical CNC lathes are common. How do they differ from each other? It depends on the type of machining parts and project requirements. Note that each type is ideal for unique applications & requirements.

CNC Milling

CNC milling machines also perform similar operations as turning machines do. The only difference is that in milling, the cutting tool rotates. Here, the workpiece remains steady & securely attached to a clamp. What can you make from this device? You can create intricate shapes, pockets, slots, and contours on a workpiece.
VMC & HMC are the two most popular CNC milling machines. VMC is a vertical machining center, and HMC is a horizontal machining center. Besides, there are types as well. The choice of a CNC milling machine depends on the specific requirements of a project. These requirements may include the size & complexity of parts, production volume, and materials.

CNC Drilling

This machining method is good for making holes. It doesn’t create different shapes like CNC milling & turning machines. Please focus on this part. [ Drill creates holes, mill shapes complex parts and lathe makes cylindrical or conical parts].
CNC drilling is widely popular in industries where hole placement, size, and depth are critical. These types of uses are demanding in aerospace, automotive, and manufacturing.

1: Design evaluation: Custom prototype helps engineers in finding the defects & errors. Therefore, based on these errors, they can take the necessary steps. These design evaluation steps may involve various testing & inspection processes.

2: Improved Quality: By evaluating the designs, engineers reconsider the prototype. They make a more efficient sample than the first one. In this way, prototypes or samples ensure the improved quality of the final part.

3: Cost-effective production: Identifying errors helps engineers reduce costly downtime. It ensures efficient production. Ultimately, it contributes to the overall profit margin of a company.

Custom Parts Machining & Prototype Machining

One of the greatest advantages of using CNC machines is the ability to create custom machining parts. It’s a cost-effective way to create high precision and tight tolerance custom parts. Prototypes are the physical objects of an engineer’s concept design. So, in short, it’s like a sample. Usually, engineers evaluate this sample before mass production to finalize the product quality.
We know custom machining parts or prototypes are crucial in modern manufacturing. You may wonder how. Let’s find out.
