Owner of Abhi Corporation has over 25 years of experiance in designing and manufacturing Roller burnishing tools and machines with brand name “Burroll”. Abhi Corporation is also engaged in manufacturing Special Purpose Machines (SPM’s) and special burnishing tools to meet buyer’s requirement.
Roller burnishing is a surface finishing technique in which hardened, highly polished steel rollers are brought into pressure contact with a softer work piece. As the pressure generated through the rollers exceeds the yield point of the work-piece material, the surface is plastically deformed by cold flowing of sub-surface material. The result is a mirror-like finish and a tough, work-hardened surface with load-carrying characteristics.
A roller burnished surface is smoother and more wear-resistant than an abraded surface of the same profilometer reading. While abrasive finishing processes remove metal and may leave sharp projections, burnishing displaces metal to form a smoother, plateau-like surface.
Roller burnishing reduces or eliminates surface sharpness and offers superior performance under working conditions in contact with mating parts. Unlike abrasive methods, it improves the surface by displacement, resulting in a better contact plane.
How It Works?!
Roller burnishing tools use pressure to plastically deform the surface layer of a material, redistributing the microscopic peaks into the valleys, which results in a smoother surface. This process does not remove material but reforms it, improving durability and finish quality.
Why Us!
Our roller burnishing tools are designed for all types of part configurations. From inside diameters to spherical surfaces and contours, we offer highly adjustable and customizable tools to suit a wide range of requirements. We provide high-quality tools and expertise to ensure your burnishing process delivers excellent results.
Reduced Friction
Burnishing creates a smoother surface that minimizes contact friction between moving parts.
Elimination of Tool Marks
Burnishing removes minor imperfections and tool marks from machining operations.
Enhanced Corrosion Resistance
The process creates a compact, work-hardened surface that resists corrosion better than abraded finishes.
Faster & Cleaner Production
Burnishing finishes and hardens parts in seconds, cleaner than honing or grinding methods.
Key Benifits
The roller burnishing process offers several key advantages, making it highly effective for precision finishing. The four primary benefits include:
- Improved Surface Finish: Achieves a finish as fine as 2 to 4 microinch.
- Improved Size Control: Maintains dimensional tolerances within .0005 inch (0.01 mm) or better.
- Increased Surface Hardness: Enhances hardness by 5% to 10% or more.
- Improved Fatigue Life: Extends fatigue life by up to 300% or more.
- Reduced Friction
- Reduced Noise Level
- Enhanced Corrosion Resistance
- Elimination of Tool Marks and Minor Surface Imperfections
- Replaces Expensive Secondary Operations such as grinding, honing, or lapping
- Cleaner Process compared to honing or other abrasive methods
- Faster Production at Lower Cost – parts are sized, finished, and work-hardened in seconds!
Roller burnishing is a fast, clean, and efficient finishing process that delivers exceptional surface quality, dimensional precision, and durability—while minimizing secondary finishing steps and production costs.
