In the medical sector, the most used Titanium alloy is Ti 6AL-4V ELI (Grade 23). This can be easily molded and has good performance in bone and joint fixation surgeries.

Other popular alloys are Titanium Beta 21STi 3Al 2.5 (Grade 12), and Titanium 15-3-3-3.

What Things To Consider In Titanium Machining Services?

Titanium CNC Machining is a popular process for manufacturing many parts from numerous industries like Medical, Automotive, Marine and Aerospace. Whatever your part is and whichever industry it is a part of, you must consider the following points while doing CNC machining with Titanium –

  • There are possibilities of adhesive wear or galling if two parts of Titanium are cold-welded.  The machining should be in such a way that seizing up can be avoided of two contact points of the metal.

Galling Can Happen While Machining Titanium

  • You should consider reducing RPM in a CNC machine while working with Titanium. Besides, you can also use a cooling machine as Titanium produces much heat at the contact points while CNC machining.
  • As Titanium is rather less flexible compared to other metals and their alloys, you should provide a hard grip on the CNC machine while working with this metal. The automation should be kept running while working on a big scale for maximum benefits.
  • The CNC machine parts should be stronger and durable compared to Titanium. Otherwise, it may lead to broken parts.
  • The tools should be as sharp as they can be because of the strong nature of this material. Besides, adding a secondary finishing stage can also help you give good polished results.

Can You Cut Titanium on a CNC Machine?

Yes, thanks to titanium’s desirable properties, titanium will not give you any type of headache when it comes to machining – not to mention CNC machining, in itself, too. Just like stainless steel, titanium can easily be welded and machined in an inert standard atmosphere.

In addition to this flexibility, titanium can also be bent and bowed multiple times in necessary conditions. So, to help you out with this further, do you know what specific CNC machines are used in processing or machining titanium?

What Material is Used to Machine Titanium?

figure 2 what material is used to machine titanium

Figure 2 – A titanium part or component cut by carbide

There is a wide array of materials used for the purpose of cutting, slicing, processing, and machining titanium. However, the most trusted material for machining titanium is none other than carbide.

Being one of the hardest and yet ductile materials in the market, carbide will never fail you when you are looking to machine titanium.

Besides the fact that it has a wide temperature range, it also boasts of a high thermal conductivity, high elasticity modulus, and it would not break down even if subdued to pressure and force – that is tolerable, of course.

Carbide is labelled only as the best in machining titanium. However, apart from carbide, you’ll also be able to find other materials such as ceramics, cast alloys, and even high-speed steel.

NOTE: Some manufacturers also use laser cutting, waterjet cutting, and even plasma cutting machines in slicing and machining titanium!

What Titanium Parts and Components Can You CNC Machine?

Figure 3 – Titanium-built turbine blades

There are a lot of titanium parts and components you can find that are actually made via CNC machines. And although the majority of these products would have the subtlest and slightest of differences, you will notice their indifferences especially when it comes to the measurements and overall precision and accuracy of the parts and components.

To name some of the few most common parts and components CNC machines have made in history, here they are:

  • Turbine Blades and Engines
  • Engine Parts and Components
  • Medical Screws and Latches
  • Dental and Medical Implants
  • Discs and Shafts
  • And Many More!

What Grade of Titanium is the Easiest to Machine?

According to expert structural engineers and professional manufacturers, the best and most convenient titanium grade to manufacture is Pure Titanium. The reason for this is because of three (3) major factors:

  • They have extremely high flexibility
  • The heat conductivity of titanium is low
  • Most titanium alloys have high hardness levels
  • They are ultimately lightweight, making it easy to machine

Although pure titanium alloys are what many experts consider the easiest and most convenient to machine, we here at HDC Manufacturing choose Titanium Grade 5 for most parts and components that require it.

Besides the fact that it has a relatively low thermal conductivity, it’s also not going to mess and tamper with the overall condition of it because the temperature will be maintained even while it’s being processed or machined.

So, in case you have questions and doubts between using stainless steel and titanium in terms of machining, here are the differences they have! Now, you don’t have to guess what’s better for the current project that you are working on!

Why Is Titanium Difficult To Machine?

Many reasons make Titanium a little difficult to work with –

  • The formation of Titanium requires much more strength than other materials
  • Because of surface oxidation and lower thermal conductivity, the tools cutting the material can lose their edge quite easily
  • The swarf of Titanium are flammable and can create problem in case of a fire in the working place
  • It has a 40-50% lower elasticity modulus than that of steel and its alloys which can increase uncomfortability to work with it
  • Automation is very difficult if you are not working with the right people. A slight difference in the automation process from the recommended one can lead to the jeopardy of your production

How To Achieve High-Speed Titanium Machining?

Because of its properties, Titanium is a good material to work with. But for the same reasons, you may find it difficult to increase the production speed with Titanium machining. But there are certain techniques to increase the speed.

You Should Choose The Perfect Cutting Tools For High Speed Machining

Cutting Tools

Cutting Tools must be chosen according to the properties of Titanium to get the best speed possible. The material used in the cutting tools is the key for high-speed manufacturing. The material in the tool should be –

  • Highly resistant to temperature
  • They cannot mix with Titanium chemically while the temperature is high
  • The strength and durability of the material should be pretty high
  • Need good thermal conductivity rate

Turning With Rotary Inserts

This technology has around passing path for the material and cuts the metal without giving it the time to heat up. So, this can be easily used for turning Titanium without having risk of temperature.

Cutting With Ledge Tools

You can use tools that have thin protruding ledges to cut Titanium. Chipping and flanking with these tools can be easy and speedy. The chips are very thin and can be used in many parts’ production. These types of tools were first developed by General Electric.

Ultrasonic Vibration

You can use ultrasonic vibration to remove the extra metal for giving Titanium the shape you desire. If you use ultrasonic vibration to your tools, the process becomes much easier and the force helps to give the cutting tools better longevity.

If you can apply the above-mentioned strategies, then you can surely pace up the speed of titanium machining. Certainly elasticity, temperature and high strength are the three key parts that can meddle with titanium machining. If you can match your tools with these properties, then you can certainly have a high-speed manufacturing process.

Which Grade Of Titanium Is Best For Machining?

Various grades of titanium are available in the market. Titanium alloys are good in strength, ductility, and durability.

Grade 1-4 titanium has hardness 100, 90, 80, and 70 giving them machinability 46%, 40%, 35%, and 28%. These are basically the easiest materials to machine.

Many Surgical Accessories Are Made From Titanium

When it comes to alloys, almost 50% of all titanium used in machining are of Grade 5 Titanium Ti-6Al-4V, 4906, 4920, 4928. This Alpha-Beta alloy has good properties for machining and manufacturing products for different industries like medical, marine, and aerospace.

Why are titanium parts important for your industry?

Titanium parts are considered to be one of the best materials for use in multiple industries. This is because titanium and its alloys possess certain qualities that make the material one of the most loved metallic alloys in certain spheres of the industry. So what are the properties that make titanium parts so special? let’s find out here:

·         High tensile strength

Titanium parts have higher tensile strength than a lot of other metallic alloys. So much so, that a few titanium alloys have tensile strength equal to that of low-grade stainless steel. This makes titanium and its alloys a great choice for application in areas where higher tensile strength metal is required.

·         Higher-strength to density ratio

One of the greatest properties of titanium is that it has a very high strength-to-weight ratio. This means that titanium parts can provide you the same strength at a much lower weight. As a result, titanium is a very popular material when it comes to saving weight like in Aircraft.

·         Low thermal conductivity

Since titanium parts have lower thermal conductivity it is safe to use these parts in areas of heat generation. This includes exhaust areas of cars where the temperature is elevated.

·         Resistant against shearing

Unlike a lot of other metals, titanium requires a very sharp cutting tool to be shaped. This means that it is resistant to normal wear and tear that parts experience. This property of titanium makes it a first choice for a lot of application areas.custom cnc titanium parts 2

·         Higher modulus of elasticity

Due to the higher modulus of elasticity, titanium is an efficient material for use in the construction of springs. This means that titanium-made products reach the same level of elasticity much earlier than other available options in the industry.

·         Corrosion-resistant

Corrosion is one of the major issues that you have to consider while selecting a part. However, titanium has a quick oxidation process which forms a protective layer on the titanium material. Subsequently, the material is protected against corrosion.

These are just a few of the advantages of using titanium parts. Now let’s have a look at which industries make use of titanium as a go-to solution for their industries.

What are the major industries that use titanium parts?

·         Aerospace Industry

The aerospace industry widely uses titanium products due to their high strength to density ratio. Titanium parts are often used in aircraft, missiles, rockets, and spacecraft.

·         Jewelry

Titanium rings and other such jewelry are very popular nowadays. This is because titanium parts do not corrode with time neither do they deform. Therefore, titanium becomes the first choice for jewelry for all those who do not want to invest in gold and silver.

·         Medical Equipment

Upon research, it has been found that the gum metal, i.e. the titanium alloys with Nb, Ta, and Zr have properties similar to that of human bones. As a result, this alloy serves as a perfect solution for the creation of prosthetics. Furthermore, due to its corrosion-resistant properties, the titanium parts are also good choice to make bone screws, that are very homogenous with the human anatomy. In addition to these, there are multiple applications of titanium in the medical industry.custom cnc titanium parts 3
