High speed cnc machining guide for titanium alloy precision parts

December 2, 2022

Most manufacturers find themselves neglecting titanium alloys as raw materials. This is mainly due to its unique functions. The latest advances in technology and metallurgy enable us to look at titanium from another perspective. However, the use of titanium alloys will cause a series of problems. Fortunately, our team of experts in Vermeer is good at dealing with challenges. We provide good quality control for titanium alloy parts processed with high precision. The following guidelines will describe how we can achieve high-speed titanium processing.
Titanium alloys provide a better weight to strength ratio than steel under ideal conditions. It also has strong corrosion resistance and is well matched with human tissues. In addition, it provides excellent performance even at very high temperatures. Its light weight and strength make it an ideal choice in the aerospace field.

What are the most common types of titanium alloys?
Due to the addition of elements, titanium alloys appear in different forms. These elements help to improve the function of titanium alloy parts. Titanium may change at temperatures above 800 degrees. Some elements will lower the temperature of the titanium used. We call them beta stabilizers. Some elements raise the temperature of the titanium used. We call these alpha stabilizers. We divided titanium alloys into four groups. This depends on the type of stabilizer present. Understanding the alloy variants you are working on is the key to cnc machining of high-speed titanium alloys. These groups are:


Unalloyed titanium
This refers only to the basic form of titanium. This unalloyed titanium form provides the best corrosion resistance. However, compared with other variants, its strength is lower.
Alpha titanium alloy
This type of titanium provides better creep resistance. Therefore, we use it for high temperature performance.
α-β alloy


This is the most diverse group because it provides great functionality. Existing α The components increase heat resistance, while β The components increase the strength. This mixture sometimes accounts for about 50% of the total titanium alloy market.
β alloy

It is the alloy group with the highest hardness at present. It is also denser than the previous alloy group.
What are the reasons that limit high-speed titanium cnc machining?
There are many reasons why titanium is difficult to machine. We will introduce them without further studying the mechanical principles of titanium grinding, milling or turning. The following are the key points for titanium to perform tasks on the machine.
High speed titanium alloy processing
First, titanium can maintain its great strength even at high temperatures. In addition, it can maintain resistance to plastic deformation even at high cutting speeds. Therefore, we finally used a larger cutting force different from that of steel. This will eventually damage high-speed titanium processing.

Secondly, its chips are very thin after forming. Therefore, the contact area between the tool and the chip is ultimately 3 times smaller than that of steel. Therefore, the tip of the tool eventually bears most of the cutting force.
Third, titanium alloys usually have higher friction coefficients than most cutting tools. We finally had to increase the cutting force and temperature. Therefore, this limits high-speed titanium processing.
Fourth, titanium sometimes reacts with tool materials at temperatures above 500 degrees. It also tends to self ignite when cutting after high temperatures have accumulated. Therefore, we will eventually use coolant when cutting titanium alloy. The time taken by this process will interfere with high-speed titanium processing.
Fifth, most of the heat generated in the cutting process enters the cutting process. This is due to the very thin chip and low contact area. This will eventually reduce its life. We eventually use high pressure coolant to prevent heat build-up.
