Precision Manufacturing for Superior Performance
Honed ID tubing undergoes a precision machining process that enhances the inner surface of the tube, resulting in:
- Superior surface finish for improved performance
- Tighter dimensional tolerances ensuring precise fitment
- Consistent internal diameter for uniform fluid flow
- Enhanced roundness reducing irregularities
- Reduced friction for smoother operation
The Honing Process
The honing process involves the use of abrasive stones that remove material from the tube’s inner surface. This is achieved while either the tube rotates or the honing tool moves through it. The result is a distinctive crosshatch pattern that:
- Improves lubrication retention for better efficiency
- Reduces wear on mating components
- Enhances sealing characteristics for hydraulic and pneumatic systems
- Ensures smooth operation in high-performance applications
Honed ID with Chrome-Plated OD: A Powerful Combination
Honed ID tubing is frequently paired with a chrome-plated OD, offering several benefits:
- Increased wear resistance on both internal and external surfaces
- Enhanced corrosion resistance for longevity
- Optimized surface finish for improved sliding and sealing capabilities
- Superior performance in demanding hydraulic cylinder applications
This combination makes honed ID tubing an ideal choice for applications requiring precision, durability, and reliability in hydraulic and pneumatic systems.
The 1020 grade is typically used for smaller diameter, thin-wall applications, while 1026 is available in larger wall thicknesses (up to 0.750" and beyond for DOM processing).
