CNC Machining ABS

ABS Plastic: A Versatile Material for CNC Machined Parts

Acrylonitrile Butadiene Styrene, or ABS, is a widely recognized thermoplastic polymer that serves as an excellent material for CNC machining. This versatile plastic is created through the copolymerization process involving acrylonitrile, butadiene, and styrene, each contributing unique properties to the final product.

The proportions of these three monomers can be varied to produce ABS with different characteristics and melting temperatures. By blending ABS with other plastics or additives, its functionality can be expanded, resulting in variations that offer improved impact resistance, heat resistance, flame retardancy, transparency, reinforcement, and suitability for electroplating.

Understanding the Typical Properties of ABS Resin for Machining

ABS resin is a versatile plastic material that is widely used in CNC machining for its balance of mechanical properties and ease of fabrication. Below is a breakdown of the typical properties of ABS resin across various types, each tailored for specific performance needs:

Performance Categories:


Medium Impact Type

High Impact Type

Heat-Resistant Type

Electroplating Type


ABS has a density range from 1.02 to 1.06 g/cm3, with slight variations depending on the type, indicating a relatively consistent mass across different grades.

Tensile Strength:

The tensile strength of ABS can range from 33 to 52 MPa, with medium and heat-resistant types showing higher strength. This indicates the material's ability to resist tension without breaking.


ABS exhibits an elongation percentage between 10 and 70%, with the high impact type offering the greatest stretchability before failure, which is essential for parts requiring flexibility.

Bending Strength:

With a bending strength ranging from 55 to 90 MPa, ABS can maintain its structure under a bending load, making it suitable for applications needing rigidity.

Flexural Elastic Modulus:

The flexural elastic modulus of ABS spans from 1.8 to 2.8 GPa, with the heat-resistant and electroplating types offering higher stiffness, which is important for maintaining shape under stress.

Izod Notched Impact Strength:

Measuring from 105 to 440 J/m at 23℃, this property illustrates the material's ability to withstand sudden impacts, with the high impact type exhibiting the greatest resistance.

Rockwell Hardness:

ABS shows a Rockwell hardness range of 88 to 112 (R), with heat-resistant types being the hardest. This measure of hardness is important for wear and scratch resistance.

Heat Distortion Temperature:

The heat distortion temperature varies from 87 to 121℃, indicating the temperature at which the material will deform under a specific load, with the heat-resistant type offering the highest resistance.

Linear Expansion Coefficient:

ABS expands at a rate of 6.4 to 11 × 10⁻⁵/℃, which is the measure of the material's dimensional change in response to temperature changes.

These properties of ABS resin make it a highly adaptable material for CNC machining, suitable for a broad range of applications. Whether the requirement is for high strength, flexibility, heat resistance, or suitability for electroplating, ABS resin offers the necessary characteristics to produce reliable and high-performance machined parts.
