Additionally, when working with titanium, it’s crucial to consider your feed rates, spindle speeds, and chip loads. This entails limiting the stress placed on tools and equipment and avoiding staying too long in one place. An alternate cutting strategy, such as increasing axial cut depth while decreasing radial engagement, may also be worth investigating to increase cutting effectiveness and lower machining temperatures.

Titanium is harder to machine than steel, primarily due to its high melting point. It is also very malleable and often stretches before breaking, making it harder to machine.

This is also known as workhorse titanium. It has high corrosion resistance, strength, formability, weldability, ductility, and low strength. Grade 2 titanium finds application in the medical and aerospace industries for producing aircraft engines.

An effective aid is a high-pressure cooling system. A spindle could also be essential, depending on the application. Increasing coolant concentration may also prove beneficial when working with titanium.

Besides, this metal has a low modulus of elasticity compared to its high strength, consequently making it a gummy material to machine. Being gummy, titanium may adhere to the CNC cutting tool, resulting in failure and damage. Aside from tool damage, galling often compromises the surface finish quality of titanium.

You must increase the number of end mill flutes to get product cycle times. For titanium, more teeth equals less chatter. For instance, a 10-flute end mill, while tight for the chip loads ideal for most materials, is perfect for use with titanium. This is primarily due to the need to reduce radial engagements.

The key benefits of CNC titanium as a manufacturing material include its superior biocompatibility, high degree of corrosion resistance, and the highest strength-to-weight ratio of any metal. This metal also has excellent ductility and good machinability. Other reasons to choose titanium for CNC machining parts include:

Coatings can greatly improve your tooling’s capacity to endure the heat produced by titanium. TiAlN (Titanium Aluminum Nitride) is a suitable coating to consider. It imparts lubricity to combat built-up edges, galling, and chip welding and is especially well suited to the temperatures experienced in machining.

The rebate amount will be calculated automatically based on the number of employees you had in the designated provinces between 2019 and 2023, multiplied by a payment rate for each of those provinces and years.

Maintaining a cool temperature while machining titanium is one of the hardest challenges. The reason is that titanium has a low thermal conductivity, which causes the metal workpiece to build up heat where the tooling is fast. This wears out faster and could negatively impact the quality of cut surfaces if it is not handled, especially when machining harder titanium alloys.

This grade of titanium has high strength and corrosion resistance. However, it isn’t easy to machine, often requiring high quantities of coolant and feed rate. Grade 4 titanium finds application in cryogenic vessels, CPI equipment, airframe components, heat exchangers, etc.

Avoid interrupted cuts as much as possible since they can hammer chips into your sharp-edged tools, possibly leading to early tool failure.

Grade 12 titanium is quite expensive and contains 0.8% nickel and 0.3% molybdenum, giving it excellent weldability, strength at high temperatures, and corrosion resistance. It finds application in shell and heat exchangers, marine and aircraft components, etc.

Also, titanium alloys need high cutting forces, which makes them difficult to cut. These cutting forces often cause tool wear, faulty parts, and high vibration, consequently impacting product quality and surface finish.

Many machine shops hesitate to work with this cutting-edge material because of the difficulties of titanium machining. However, due to its exceptional qualities, many manufacturers are opting to use titanium to produce high-quality parts.
