Diamond Burnishing Tools
Our diamond burnishing tools deliver an efficient solution for producing exceptional surface finishes on flat surfaces, contours, and bores starting at 16 mm in diameter. Equipped with highly polished diamond tips, they significantly reduce surface roughness—down to Ra 0.2 µm (Rz < 1), depending on the workpiece material and pre-machining. The result is outstanding surface quality, excellent process reliability, and cost-effective finishing in a single operation.
Your Benefits
Highest surface quality up to mirror finish with low sliding friction
Long tool life due to wear-resistant diamond tip
Easy handling without tool changes for different diameters
High cost-effectiveness through efficient machining and low maintenance costs
Flexible machining of internal and external surfaces
Environmentally friendly process without grinding dust or chips
Diamond burnishing tools enable burr-free fine finishing of surfaces and significantly improve surface quality. Controlled burnishing smooths out roughness peaks and densifies the surface, positively affecting wear behavior, running and sliding properties, as well as component service life.
The process can be directly integrated into existing manufacturing workflows and is suitable for machining on lathes, machining centers, and special machines. Due to high process reliability and reproducible results, subsequent machining operations can often be reduced or even eliminated.
Rely on our diamond burnishing tools to enhance surface quality and process reliability in your production while simultaneously reducing manufacturing costs.
If no standard tool fits your application, we are happy to develop a custom-made solution tailored to your needs.
High-Precision Solutions for Burnishing Surfaces
The diamond tips are replaceable and can be resharpened and polished multiple times, ensuring cost-effective maintenance and long tool life. Our tools are especially suitable for ductile metallic materials such as carbon steel, tool steel, as well as ferrous and non-ferrous metals. The tool’s performance remains consistent and reliable even during interrupted cuts.
Unlike roller burnishing tools, diamond burnishing tools have no moving parts, resulting in lower wear and easier maintenance. Additionally, these tools offer greater flexibility compared to roller burnishing tools, as a diamond burnishing tool can machine various diameters both internally and externally without the need for tool reconfiguration. These tools are also ideal for machining thin-walled components and tubes, which are challenging to process with conventional methods. In the best case, using diamond tools saves valuable time, as often a single machining pass is sufficient to produce highly reflective and densified surfaces—with outstanding results!
Planar diamond burnishing tools are particularly well suited for machining larger flat surfaces, for example on machining centers. The tool types DBFM63, DBFM80, DBFM100, and DBFM125 feature multiple spring-mounted diamond inserts that are precisely coordinated. This allows surfaces to be reliably smoothed and densified in a single operation immediately after milling. The tools consist of a tool body and replaceable diamond inserts, making them economical and suitable for nearly all materials—from carbon steel and tool steel to cast alloys and ferrous and non-ferrous metals.
The diamonds enable high-quality surface finishes while simultaneously densifying the surface. For example, in gray cast iron, an initial Ra value of 2–3 µm can be reduced to a final value of 0.2–0.4 µm.
