Introduction

CNC (Computer Numerical Control) turning is a machining process that utilizes computerized controls to rotate a workpiece while a cutting tool removes material. This process is essential in manufacturing various precision parts and products. Selection of materials for CNC turning can significantly affect product quality, manufacturing cost, and application areas. This article provides an in-depth look into the types of materials that can be used in CNC turning, including the solutions provided by Dongguan Longying Company.

Materials Used in CNC Turning

Metals

Metals are commonly used in CNC turning due to their strength, durability, and versatility. The following metals are widely utilized:

• Aluminum: Known for its lightweight and excellent machinability, aluminum is often used in aerospace and automotive industries. Common grades include 6061 and 7075, offering tensile strengths of approximately 310 MPa and 570 MPa, respectively.
• Steel: Steel grades such as 1018, 1045, and 4140 are frequently used, with tensile strengths ranging from 440 MPa to 655 MPa. Steel is used in constructing heavy-duty parts due to its durability.
• Brass: Offering excellent acoustic properties and corrosion resistance, brass (e.g., C36000) is used in electrical components, with a tensile strength of about 345 MPa.
• Stainless Steel: Known for corrosion resistance, stainless steel types such as 304 and 316 have tensile strengths between 515 MPa and 620 MPa, suitable for medical instruments and food processing equipment.
• Titanium: Due to its high strength-to-weight ratio (tensile strength ~ 830 MPa), titanium is used in aerospace and high-performance applications.

Plastics

Plastics are increasingly used in CNC turning due to their lightweight and corrosion resistance. Popular types include:

• ABS: Known for its impact resistance, ABS offers a moderate tensile strength of around 41 MPa, making it suitable for consumer products.
• Polycarbonate: With a tensile strength of about 70 MPa, polycarbonate is used for impact-resistant applications.
• Nylon: Offers a balance of strength, flexibility, and resistance, with tensile strengths around 76 MPa.
• Delrin: Preferred for its rigidity and dielectric properties, Delrin (acetal) has a tensile strength up to 110 MPa.

Other Materials

Beyond metals and plastics, CNC turning also uses materials such as:

• Wood: Although less common, certain hard woods can be machined for decorative or functional components.
• Ceramics: Used in high-wear applications due to their hardness and temperature stability.
