CNC Machining Of Titanium

Titanium CNC Machining In Tirapid

Titanium is a kind of non-magnetic, its hardness is higher than that of steel, its density (4.5g/㎥) is lower than that of steel, and it is larger than that of aluminum. Titanium is an expensive metal material among metals.

Titanium and titanium alloys are the most widely used in the aerospace industry, which is also determined by the properties of titanium itself. Titanium is harder and less dense than steel.

For the same volume, titanium is several times lighter than steel. In the same harsh environment, titanium has a longer service life than steel, and has strong fatigue resistance and corrosion resistance.

What are the common types of titanium materials?

Grade 1-4 titanium:

Grade 1-4 titanium is often called pure titanium, and it is also a commonly used commercial pure titanium, which is the most suitable type of titanium for processing.

Grade 5 titanium:

Also known as Ti6Al4V or Ti-6AL-4V, it is an alloy containing 6% aluminum and 4% vanadium. It is commonly used in medical equipment and is a commonly used titanium alloy metal material. Grade 5 titanium is the more machinist’s choice and accounts for about 1/2 of the titanium material.

Why use titanium?

Titanium is a special metal material. Titanium has strong corrosion resistance, light weight and long service life. Aerospace, medical devices, submarine ships, luxury cars, racing cars, sports cars and other high-end fields will choose such excellent materials.

Advantages of Titanium:

Titanium is a non-magnetic metal material and can automatically repair the surface in harsh environments, and its corrosion resistance is a representative position in all metals. Titanium alloy is often used as one of the material choices for implants, and it is also the metal material with the lowest sensitivity to the human body, and its biocompatibility is very good.

Disadvantages of Titanium:

Titanium is one of the most difficult steel materials to process in machining. Titanium has poor thermal conductivity and requires high cutting tools during machining. The high requirements for processing equipment eventually lead to higher processing costs for parts, and the material of titanium is many times higher than that of steel and aluminum.

Titanium machining problems

The machining of titanium has always been considered one of the most difficult processes by the machining industry, due to its high tensile strength, low ductility, and very low thermal conductivity. Therefore, Tirapid summarizes the precautions for processing titanium to help you complete your titanium processing project more efficiently during the processing.

First of all, the machine tool for machining titanium, like the machine tool for machining steel, needs to be strong enough. Tirapid is usually processed by the 850 type machine tool. The machine tool has good stability, which can better ensure that the tool will not chatter during the processing, and the tolerance deviation is smaller.

Secondly, the programming method of the mechanical engineer is very important, titanium is more difficult to machine than steel, so in CNC machining, CNC titanium machining or titanium alloys, every link is crucial. Therefore, the design of the tool path is closer to the processing method of stainless steel. Climb milling is one of the most common operations for machining titanium, which can better control the surface and dimensional tolerances of the part.

The third is the tool for titanium alloy machining. Ordinary anti-CNC tools cannot meet the surface chip efficiency of parts. As we all know, when machining stainless steel, the most worrying phenomenon is sticking. The same is true for titanium alloys, so when you choose titanium machining tools, you must consider hard-coated alloy tools, which can not only solve the problem of viscosity, but also effectively help control the heat generated during processing. Recommended knives: Cubic boron nitride (CBN) or polycrystalline diamond (PCD) knives.

Fourth, coolant for titanium machining plays a key role in titanium CNC machining. During conventional aluminum alloy CNC machining, coolant can not only reduce the heat generated by CNC machining, prolong tool life, but also ensure the surface quality of parts. When processing titanium, a method of ensuring high-pressure injection must be faced. The best coolant is an emulsion rather than a pure oil.

What is the difference between titanium and other metals


In aerospace parts, the frequency of use of titanium alloy and aluminum alloy is close, they have common characteristics, light weight, the difference is that in CNC machining, titanium is not as easy to process as aluminum, and the requirements for equipment, tools and processes are very high.

Aluminum processing is the most widely used in CNC machining, and the application range of industrial, commercial, and daily necessities is also getting wider and wider. The price of titanium is far from aluminum, and the price of titanium can be close to 10 times higher than that of aluminum.


Titanium and steel are both difficult materials to cut. They have the same problem in machining, that is, the chips will stick to the knife when cutting, and the requirements for the tool are very high. In the selection of equipment, large-scale CNC machining is also required, which can ensure sufficient chip force and stability.

Titanium is better than steel, mainly in terms of density. The density of titanium is much smaller than that of steel. For parts with important requirements, only titanium can be selected for processing.
