CNC Machining Parts: Hollow Piston Rod for Roller Shaft


CNC machining has revolutionized the manufacturing industry, allowing for precise and complex components to be produced with accuracy. One such component, the Hollow Piston Rod, plays a crucial role in various applications, particularly in roller shaft assemblies. In this article, we will delve into the specifics of CNC machining parts, focusing on the Hollow Piston Rod with small diameter, thick wall, and threaded steel pipe.

Material Selection

The choice of material for a Hollow Piston Rod is critical to its performance and longevity. Common materials used for this application include:

  • Stainless Steel: Known for its corrosion resistance and durability, stainless steel is a popular choice, especially in environments prone to moisture or chemical exposure.
  • Carbon Steel: Offers high strength and toughness, making it suitable for applications with heavy loads and high stress.
  • Aluminum: Known for its lightweight properties, aluminum is used in applications where weight is a critical factor.

Drawing Format

The drawing format for CNC machining parts is typically provided in a CAD (Computer-Aided Design) file. Common formats include:

  • DWG: A widely used 2D CAD format developed by AutoCAD.
  • STL: Common for 3D printing and CNC machining, representing surface geometry.

Production Process

1. Material Preparation

  • The selected material is sourced in the form of bars or tubes, depending on the specifications.

2. CNC Machining

  • The CAD file is loaded into the CNC machine, which uses cutting tools to shape the material according to the design.

3. Drilling and Threading

  • For the Hollow Piston Rod, precise drilling and threading operations are performed to create the necessary features.

4. Turning and Milling

  • Turning is used to achieve cylindrical shapes, while milling refines intricate details.

5. Heat Treatment (Optional)

  • Depending on material and application, heat treatment may be employed to enhance properties like hardness and toughness.

Surface Roughness

Surface roughness is a crucial parameter for functional components like the Hollow Piston Rod. It is measured in Ra (arithmetical average of the absolute values of the roughness profile). The desired roughness level depends on factors such as material, application, and environment.

Treatment and Finishing

  • Plating or Coating: Depending on the material, plating or coating processes may be employed to enhance corrosion resistance or improve aesthetics.
  • Grinding and Polishing: These processes are used to achieve a precise finish and eliminate any imperfections on the surface.

Inspection Instruments

Quality control is paramount in CNC machining. Various instruments are used to inspect Hollow Piston Rods:

  • Calipers: Measure dimensions accurately.
  • Micrometers: Provide precise measurements of small features.
  • Surface Roughness Testers: Ensure the specified finish is achieved.
  • Thread Gauges: Verify the integrity of threaded portions.


The Hollow Piston Rod, with its small diameter, thick wall, and threaded steel pipe configuration, finds applications in a wide range of industries:

  • Automotive: Used in shock absorbers, steering systems, and suspension assemblies.
  • Hydraulic Systems: Critical components in hydraulic cylinders.
  • Industrial Machinery: Employed in various types of machinery for linear motion.


CNC machining has opened up new frontiers in precision engineering, enabling the production of complex components like the Hollow Piston Rod. By understanding the material selection, production process, surface roughness considerations, and application possibilities, manufacturers can optimize the performance and longevity of this vital component.
