Recognized as one of the easiest and cost-effective materials for precision machining, brass is selected for crafting intricate parts with sophisticated features. With its smooth machinability, polished finish, brass is extensively used in medical equipment, consumer goods, electronic hardware, fittings, and commercial products.


Renowned for its heat and corrosion resistance, titanium finds extensive usage in numerous industrial applications. Its immunity to salt and water corrosion makes it a preferred choice for medical implants, aircraft components, and jewelry manufacturing.


As the lightest structural metal, magnesium is widely employed by precision machining service providers. Offering excellent machinability, magnesium provides strength and durability, making it suitable for various industrial sectors.


In high demand for CNC machining, Monel is chosen for applications exposed to corrosive environments requiring higher strengths. Although tooling Monel is challenging and requires extensive experience, it remains a popular choice for specific applications.


A nickel-based superalloy, Inconel has gained popularity for its advantageous features. Ideal for environments prone to aqueous corrosion or oxidation, Inconel is suitable for applications subjected to extreme pressure and heat.

Apart from these materials, several others like Carbide, Tungsten, Palladium, Invar, Nickel, Niobium, Alloy steel, Beryllium, Cobalt, Iridium, and Molybdenum are compatible with precision CNC machining. Selecting the right material is critical for the success of applications, considering factors like application area, machining activities, and specific requirements.


Considerations for Precision Machining

Material Selection

The choice of material is critical in precision machining. Different materials have varying machinability, hardness, and thermal properties, which can affect machining processes and tool life. Selecting the right material based on the specific requirements of the part is essential for achieving optimal results.

Tolerances and Surface Finish

Precision machining requires tight tolerances and high-quality surface finishes. Define the required tolerances and surface finish early in the design phase to ensure they can be achieved through machining processes. Consider the capabilities of the machining equipment and the expertise of the machinists in meeting these requirements.

Machining Techniques

Understand the various machining techniques available, such as milling, turning, drilling, grinding, and EDM (electrical discharge machining). Each technique has its advantages and limitations, and selecting the most suitable technique depends on factors such as part geometry, material, tolerances, and surface finish requirements.

Tool Selection and Optimization

Proper selection and optimization of cutting tools are crucial for successful precision machining. Choose the right tool materials, coatings, and geometries to ensure efficient material removal, minimal tool wear, and high-quality surface finishes. Regular tool maintenance and optimization can help prolong tool life and maintain machining accuracy.

Fixture Design and Workholding 

Secure and stable workholding is essential for precision machining to prevent part movement or deflection during machining operations. Designing effective fixtures and workholding systems tailored to the specific part geometry and machining processes can enhance accuracy, repeatability, and productivity.
