Specialized CNC Machining for Automotive Suspension and Steering Systems

CNC machining is a precision manufacturing process where computer-controlled machine tools such as mills and lathes are utilized. At Great Auto Parts, we specialize in CNC machining for automotive suspension and steering systems. Our advanced equipment ensures the production of high-quality components with exact specifications. With services including face milling, threading, drilling, and more, we meet the demanding requirements of the automotive industry. Trust us for precision CNC machining tailored specifically for suspension and steering components, ensuring optimal performance and safety.

Ball Stud / Ball Rod / Ball Pin

The Ball Studs and Ball Rods are generally considered to be critical components for their applicable steering and suspension assemblies. They must follow precise manufacturing control plans, and quality check points to insure they meet the very high quality standards required by our customers.

We had Established the very first Test lab for Steering and Suspension parts, especially specific in Housing / Ball Pin / Pillow ball components, that never seen in our field in Taiwan.

The ball size range is from 10mm up to 65mm. OEM / ODM and small quantities are acceptable. Dropping test can be applied on ball pins according to customer requirements. We supply to many world class and well-known factories in manufacturing suspension and steering parts.

CNC Machined Ball Pin with Induction Hardness

Why Choose Great Auto Parts CNC Machining?

Great Auto Parts is a CNC machining parts manufacturer and a leading provider of CNC machining services. At Great Auto Parts, we use advanced CNC turning and milling equipment to offer a wide range of services, such as face milling, parting, threading, drilling, grooving, and more. We also have high-speed vertical machining centers that can produce parts for the automotive industry.

Moreover, we specialize in manufacturing ball studs for automotive suspension and steering systems. These ball studs undergo precision CNC machining processes to ensure exact specifications and high-quality standards. Additionally, our expertise extends to incorporating heat treatment techniques such as quenching and tempering into the production process.

The advantages of heat-treated ball studs in automotive suspension and steering systems are significant. Through heat treatment, these components exhibit enhanced mechanical properties, including increased strength, hardness, and fatigue resistance. This translates to improved durability and reliability, crucial factors in ensuring the safety and performance of vehicles on the road.

Furthermore, heat-treated ball studs offer superior dimensional stability, maintaining precise tolerances even under extreme operating conditions. This ensures proper alignment and functionality of suspension and steering components, contributing to overall vehicle stability and handling.
