Pros and Cons of Titanium for CNC Machining

Titanium is a prized material in CNC machining, renowned for its exceptional strength, lightweight properties, and resistance to extreme conditions. Its unique combination of features makes it indispensable in industries such as aerospace, medical, automotive, and marine engineering. However, titanium’s characteristics also present challenges, making its machining a complex and specialized process. Below is a comprehensive overview of titanium’s advantages and disadvantages as a CNC machining material.

Light Weight

Titanium combines exceptional strength with a lightweight structure, making it an ideal material for applications that require strength without adding unnecessary weight, such as in aerospace, automotive, and high-performance engineering.

Low Thermal Expansion

Titanium has a low coefficient of thermal expansion, meaning it maintains its shape and size even with temperature changes. This stability is essential for CNC Machining, where dimensional accuracy is vital, even in fluctuating thermal environments.

Biocompatibility

Due to its high biocompatibility and non-toxic nature, titanium is widely used in the medical field for implants and surgical instruments, offering a safe and effective solution that minimizes the risk of rejection or adverse reactions in the human body.

Durability

Renowned for its outstanding durability, titanium is perfectly suited for CNC-machined parts that must endure demanding conditions. It withstands high-stress, extreme temperatures, and abrasive forces, ensuring longevity and reliability in critical applications.

Non-magnetic

Titanium is non-magnetic and has excellent resistance to oxidation, which makes it highly resistant to corrosion and rust. This unique combination of properties is crucial for components used in sensitive or extreme conditions, including aerospace, medical, and marine applications.

Corrosion Resistance

Titanium excels in resisting corrosion, even in the most chemically aggressive environments. Its remarkable resistance to rust, oxidation, and other forms of corrosion makes it the material of choice for marine, chemical processing, and industrial applications.

Lower Thermal Conductivity

Due to titanium’s low thermal conductivity, managing heat buildup during machining is critical. Excessive heat can accelerate tool wear and negatively impact the quality of the cut surface, making temperature control a key factor in titanium processing.

Increased Cutting Forces

The machining of titanium alloys requires higher cutting forces compared to other materials. This can result in greater tool wear, the potential for part defects, and vibrations, all of which can compromise both the quality and surface finish of the final product.

Residual and Hardening Stresses

Titanium alloys have a unique crystalline structure that limits flexibility during machining. This characteristic increases cutting forces and the likelihood of residual stresses, which can affect the overall performance and precision of the machined part.

High Chemical Reactivity

Titanium’s tendency to react with gases can lead to surface oxidation and embrittlement, weakening the material. This reaction reduces its corrosion resistance, potentially compromising the performance and longevity of titanium components in certain environments.

Types of Titanium Machining Materials

Titanium is a versatile metal widely used in CNC machining due to its unique properties, including a high strength-to-weight ratio, corrosion resistance, and excellent performance in extreme conditions. Different grades of titanium are engineered to meet the diverse requirements of industries such as aerospace, medical, automotive, marine, and energy. These grades are classified into two main categories: commercially pure titanium and titanium alloys. Below is a detailed overview of the types of titanium machining materials.

Surface Finishing Options for Titanium Machining

Surface treatments enhance the durability and aesthetics of custom titanium parts, providing additional protection against corrosion and wear. At NOBLE, we use a variety of surface treatments, such as polishing, tumbling, and brushing, to meet your specific requirements for appearance and functionality.

As Machined

Coming out of the machine after machining, our parts are cleaned of any sharp edges and burrs while retaining marks. Without any added material, the part had a surface roughness of 3.2 μm (126 μin).

Polishing

Working on metal and hard plastics, our polishing uses highly efficient machinery to get our parts between Ra 0.8~Ra0.1 for a cleaner surface.

Sand Blasting

Sand blasting cleans the surface of any impurities and peels coating through the propelling of blast media streams over the parts.

Tumbling

Tumbling titanium smooths its surface, often resulting in a matte finish. It’s used for deburring or preparing titanium parts for further finishing or aesthetic enhancement.

Laser Carving

Helpful in brand recognition or parts organization, we use laser carving that applies various printing methods during full-scale production to quickly embed barcodes, lettering and logos on the parts.

Alodine

We use chromate conversion coating or alodine to protect aluminum and other materials from corrosive elements, usually done before priming and painting parts.

Anodizing

To increase surface hardness and dissipate heat, we use anodizing techniques to enhance the look of parts and blend well for painting and priming.

Powder Coating

We apply a thin layer of protective polymer with the corona discharge phenomenon to give our part a lasting finish that protects from impacts and prevents wearing down.

Brushing

Our brushing technique uses abrasive belts over the material to create diverse patterns that match the parts’ structure and color.
