What is 5 Axis CNC Milling?

It was discussed in our previous blog post that CNC or Computer Numerical Control Milling is an innovation that helps certain industries to make their production faster. This time, we’ll discuss about 5 Axis CNC Milling, a type of CNC milling that doubles up the speed and accuracy of the production.

5 Axis CNC Milling is a process where the CNC tool moves in 4 or more ways. This is used most especially for gears that need curved holes like impellers, turbines and aerospace airframes. Since the structure of these gears needs intricate details, 5 Axis CNC Milling is the best to use. What’s unknown to common people is that the advanced tool is not only capable of making detailed metal works; it is also capable of maintaining consistent acceleration and deceleration, which are very vital characteristics for the said types of gear. It is also good to take note that the majority of the by products of 5 Axis CNC milling are parts that require tight holding tolerance.

The typical axis milling is the 3 Axis Milling. However, investing for a 5 Axis Machining tool makes sense for it allows CNC machine shops to accept more complex part orders. This is because your spindle usage is also increased.

WHAT ARE THE BENEFITS OF 5 AXIS CNC MILLING?

Since 5 Axis CNC milling uses more axes to produce better output, it is expected that using the tool can:
1. Enable you to produce complex gears. In a single setup which saves time, cost and operator error, a 5 Axis CNC milling tool can help you produce complex gears in no time.
2. Enable you to save time in production. Drilling a number of holes in a gear can take time if the machine that you are using is not equipped to do the job. In a 5 Axis CNC milling machine, you can drill a series of holes even with different compound angles in no time.
3. Make better surface finish. If properly aligned perpendicularly to the surface, the tool can enable you to cut your gears in a quick manner with a high precision.
4. Set you above the competition. We have mentioned that most CNC machining companies only use 3 Axis CNC machines. Only a few companies use 5 Axis CNC machines because they are a bit costly. However, investing for the machine is a good move because there will be few competitors resulting to higher profit margins.

IMPORTANT TO TAKE NOTE:
There are some CNC machines that do not require the operator to be highly skilled because the machine is computer generated. 5 Axis CNC milling uses CAM or Computer Aided Manufacturing, too. However, this equipment requires better skill for the operator because the person who will operate should know the preventive maintenance of the device, as well as the responsive technical service when needs arise.

The Importance of Correct Programming in CNC




Correct programming and formatting of codes are very important when it comes to running CNC machines. CNC machining play a vital role in the industrial field. They produce very intricate and precise parts of things that are highly needed in the industrial sector, such as parts of a watch, parts of a plane and other similar items. These things are special objects that have very minute details that only CNC machines could produce.

How do CNC machines operate?

CNC machines operate through a set of codes or instructions that is also known as program. These codes are specially created to guide a CNC machine into performing a specific action. These set of instructions make it possible for the machine to produce the desired effect without any difficulty. A CNC machine commonly has several axes that allow it to make very accurate cuts and designs.


What is a G-code?

G-code or G programming language is the name of the most common program that is used on CNC machines. This determines how fast a machine should work, on which direction and the like. Technically, this is what the machine follows on how it should operate.


Why is correct programming very important?

CNC machines are not cheap, but they are very good investments once set into production. Inaccurate setting up may result to a product that is not worth anything, therefore incurring loss instead of profit. In addition to this, wrong programming may lead to a crash tool, which can only add up to the loss.  


Why are CNC machines indispensable today?

In these modern times, we require high tech machines that can produce quality products in a short period of time. The industry also relies on the productivity of these machines. They can operate for long hours without any supervision, making them ideal for large scale orders or mass production. These CNC machines only need to be programmed accordingly and they can be relied to produce the desired parts, without worrying about uniformity. Until the invention of CNC machines, the industry had to depend on the skills of the machinist to produce very intricate designs. These machines have truly changed the way production in the industrial field works.


Proper setting up and programming of the code is crucial to ensure that the CNC machines are going to perform as expected and that the quality of the parts they produce are exactly as planned.

Anodizing CNC By-products

CNC (ComputerNumerical Control) has touched almost every form of manufacturing process in one way or another. However, manufacturing companies are not the only ones who need CNC in running their business everyday; companies that need specialized gears and tools need the ramification of CNC in completing the operation of their machineries for their business as well.

A CNC machine is programmable and easy to operate. In fact, one person can supervise many CNC machines because once the machines are programmed, they can usually be left to work by themselves.  Since the first asset offered by CNC machining tools is improved automation, the operation of the machinery has caused reduction of fatigue on the operator’s part – fewer mistakes were made and the operation became predictable and consistent. However, a CNC programmer must have the extensive knowledge of how the machine processes.

CNC has truly revolutionized the way intricate gears and parts were made. It has: 1) formed high accuracy in manufacturing, 2) shortened production time, 3) opened opportunity for greater manufacturing flexibility, 4) provided simpler fixturing, 5) contoured machining and 6) reduced human error. However, a craftily made CNC product will only be at its best when it is anodized.

Anodizing, in simple terms, is the process of coating with metallic material. Digging deeper, anodizing is the process in which electrolytic cells undergoes passivation in order to increase the thickness of natural oxide layer on the surface of metal parts. Anodic films are commonly applied to protect CNC by-products that are made from aluminium alloy, titanium, zinc, magnesium, niobium, zirconium, hafnium and tantalum.


Basically, anodizing is done to make the CNC by-products double its durability. But furthermore, CNC anodizing will also:
  • Increase the corrosion resistance of the products. Corrosion occurs when manufactured metals go back to their natural oxidation states. Since anodizing is the application of thick coatings to metals, the process will literally make the “pores” of the decrease its size. In this way, corrosion resistance is achieved.
  • Provide better adhesion for paint primers. Since bare aluminum is reactive with air, it will begin to reform to oxide to protect itself. However, when anodizing is done, the surface will be non-reactive or inert and this will cause the paint to be more adhesive.
  • Make your CNC product more tenacious. Anodic films are much stronger and more adherent that other paints and metal plating. However, they are also more brittle. These attributes makes the films coat the metal and decrease its likeness to crack and peel.
Here are some of our products that have undergone anodizing:




Anodizing was a very old practice that started in the early 30’s. Over time, it was developed for commercial use. The modification of the process, as it has developed, has made anodizing safe and not harmful to human health. Products that are finished through anodizing are usually non-toxic and chemically stable.


What Are The Advantages of CNC Milling?

CNC Milling is a technique that is used on machines, programmed with special codes, to perform specific movements that allow it to cut materials like metal, steel and plastic and produce intricate designs. Because of this advancement in technology, CNC machines became very popular and are used widely in the manufacturing industry today.

CNC Milling has a number of advantages and these are:

Precision - precision is also a big factor why CNC Milling had a huge impact on the manufacturing industry. Before its time, everything relied to the skills of the machinist. The quality of work with CNC Milling has become more accurate and 3D designs were even made possible. In addition to this, the number of rejects dwindled dramatically.

Automated Cooling - one of the advantages of  CNC Milling is automated cooling. There are no more worries about having machines overheat or cause damages.

Speed - it is obvious that programmed machines work way faster than having a machinist operate it manually. On average, it is about 5 times faster than the traditional style. With this innovation, the industry has been more productive than never before.

Repeated Use - perhaps one of the best advantages of CNC Milling is that the programs can be stored and therefore be used over and over again. This only means that a metal could be cut the exact same way multiple times without worrying about uniformity and quality.


CNC Milling machines can operate 24 hours without stopping and these could be handled by people who don't have to be skilled at all. These things are equal to bigger profit for the industry of manufacturing - no need to hire highly-skilled machinists and more production time. With the invention of CNC Milling, the manufacturing industry will never be the same again.

What is CNC Milling?


CNC or Computer Numerical Control Milling is considered as the most common form of CNC. Basically, it is the extension of Numerically Controlled Milling or NC. As it turned out, it is an invention that forever changed the manufacturing industry.

It usually has two main functions: Drilling and Turning. The number of axes a CNC mill has is usually the basis for classifying one. Axes have different labels based on their movement. 'X' and 'Y' labels are used for horizontal movements, whereas 'Z' is used for vertical movement.
