With the spirit of professionalism and excellence, DHF has made its debut with the R&D and application team. Pure titanium and titanium alloy metal, mostly used in medical and aerospace industry, its properties are difficult to cut materials. During the cutting process, iron filings are not easy to remove, and it is easy to adhere to the tool, causing secondary cutting, which shortens tool life and processing. Not efficient, but DHF's R&D team has improved it all.

Despite the high cost of titanium materials, DHF has invested in the spirit of professionalism and service, and has invested heavily in R&D, developing new knives, upgrading coatings and increasing tooling. Try again, don't be discouraged, don't compromise, and finally defeated titanium, making cutting titanium easier.
Breaking the tradition, improving efficiency and increasing the life expectancy, our titanium cutting/titanium milling series is quite complete, and the Vc value of cutting titanium under the traditional concept is only 40~60m/min, but our series products, through technology Under the test application of the team, the Vc value can reach 100~150m/min. If the cutting depth is good, the depth of cut and the width of the cut have the ability of 1D. Of course, our titanium series tools are very thin. There are different tool designs for milling grooves/grooves, side milling, face milling, and plunge milling.
In contrast, to cut titanium metal, we must first understand its metal characteristics and precautions. The following is our experience value sharing:
Titanium alloy characteristics
Titanium has a low density of 4.5 g/cm3, which is only 60% of iron. It is usually called light metal with aluminum, magnesium, etc., and its corresponding titanium alloy, aluminum alloy, and magnesium alloy are called light alloys. Many countries in the world have recognized the importance of titanium alloy materials, and have successively researched and developed titanium alloy materials, and have been put into practical use. Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields due to their high specific strength, good corrosion resistance, high heat resistance and easy welding. High strength and easy welding performance are conducive to the manufacture of aviation and aerospace industries.
The first practical titanium alloy was the Ti-6Al (aluminum)-4V (antimony) alloy successfully developed in the United States in 1954. Ti-6Al-4V alloys achieve good levels of heat resistance, strength, ductility, toughness, formability, weldability, corrosion resistance and biocompatibility. Ti-6Al-4V alloy has accounted for 75~85% of all titanium alloys.
When the hardness of the titanium alloy is greater than HB350, the cutting process is particularly difficult. When it is less than HB300, the sticking phenomenon is likely to occur and it is difficult to cut. Titanium alloy has strong chemical affinity for tool materials. Under the conditions of high cutting temperature and large cutting force per unit area, the tool is prone to bond wear. The thermal conductivity of titanium alloy is very small (corresponding to 1/5~1/7 of 45 steel), the contact length between the chip and the rake face is extremely short, and the heat generated during cutting is not easy to pass out, mainly concentrated in the cutting zone and cutting. In the small range near the blade, the temperature generated during cutting is high.
Titanium has a large chemical activity. At high cutting temperatures, it easily absorbs oxygen and nitrogen from the air to form a hard and brittle outer skin. At the same time, plastic deformation during cutting also causes surface hardening.
The chilling phenomenon not only reduces the fatigue strength of the part, but also aggravates the tool wear, which is an important feature when cutting titanium alloy.
After the blank is processed by stamping, forging and hot rolling, it forms a hard and brittle uneven skin, which is easy to cause chipping, which makes the removal of hard skin the most difficult process in titanium alloy processing.
Based on the above arguments, the focus of cutting titanium and titanium alloys is:
A-How to remove chips
B-cutting fluid
C-tool design (groove design spiral angle design blade design)
Abstract DHF has a professional and continuous spirit. With the efforts of the R&D and application team, the Titanium cutting/Titanium milling series has finally made its debut.
