Introduction

CNC turning is a highly developed manufacturing technique suitable for producing precisely turned parts. The choice of material significantly influences the performance, aesthetics, and cost of the final product. This article presents a detailed analysis of material options suitable for CNC turning, with specific parameters relevant to their mechanical properties and applications.

Materials for CNC Turning

Metals

Metals are the most commonly used materials in CNC turning due to their excellent mechanical properties. Below are some examples:

• Aluminum Alloys: Known for their lightweight and excellent corrosion resistance. Suitable for aerospace parts. Common grades include 6061-T6, offering a tensile strength of around 290 MPa.
• Stainless Steel: Offers high strength and corrosion resistance. Widely used in medical and automotive industries. AISI 304 and AISI 316 are typical grades, with tensile strengths ranging from 505 to 620 MPa.
• Brass: Excellent machinability and corrosion resistance. Ideal for fittings and fixtures. Comprising around 60% copper content, it provides lower friction.
• Titanium: Stands out for its high strength-to-weight ratio and biocompatibility, particularly suitable for medical implants. Grade 5 titanium is widely used with a tensile strength of approximately 950 MPa.

Plastics

Plastics provide versatility and cost-efficiency in CNC turning applications. Important plastic materials include:

• ABS: Offers impact resistance and ease of machining, with a tensile strength typically around 40 MPa. Suitable for prototypes and enclosures.
• Delrin (POM): Features low friction and high wear resistance, making it perfect for precision engineering parts.
• Nylon: Recognized for its wear resistance and lower coefficient of friction. Often used in gear manufacture and automotive components.

Composites

Composite materials combine multiple elements to optimize performance attributes, suitable for various high-stress applications. They include:

• Carbon Fiber Composites: Provide an excellent strength-to-weight ratio, useful in aerospace and sports equipment. Typically have tensile strengths over 1,500 MPa.
• Fiberglass: Often used for its insulation properties and tensile strength of approximately 1,200 MPa.
