Optimization of Metal Surface

For almost 50 years Baublies AG has been one of the few companies specializing in roller burnishing technology.

Roller burnishing is a highly efficient and future oriented process for optimizing metal surfaces. Baublies AG delivers innovative and sophisticated solutions of excellent quality developed with a creative approach, and offer the user maximum economy and durability.

Roller Burnishing is a chip less smoothing and compression process for metallic surfaces achieved by rolling elements. During roller burnishing, the forming elements are loaded with a vertically directed force to the surface (roller burnishing force). Thereby the roughness profile is plastically deformed and levelled. Roller burnishing changes the stress condition in the surface layer of the material which is a method of micro finishing.

Ra LESS THAN A MICRO

The benefit of roller burnishing is the economical, simple and reliable manufacturing of maximum surface quality while increasing the strength and hardness of the workpiece.

The are multiple benefits of roller burnishing. Mirror like surfaces with roughness is below 1μm. High material ratio of the profile creating optimized the wear characteristics. It is also reduced the risk of crack formation caused by micro notches. Moreover, corrosion resistance will be improved.

The roller burnishing force produces a surface pressing in the contact zone of the burnishing elements. Thereby the flow limit of the material is reached in the contact area and thus the surface profile is plastically deformed and levelled. The material volume of the elevated areas of profile peaks is pressed out into the levelling profile valleys. Thus the surface roughness is significantly reduced. The resulting dimensional difference between the pre-worked and the roller burnished workpiece depends on the original roughness.

Smoothing and Work-Hardening in New Dimensions

Diamond-burnishing tools expand the range of applications of roller burnishing technology, as even hardened materials up to approximately 60 HRC can be roller burnished. In the process, a high-precision, micro-polished diamond glides over the surface. As soon as the yield point of the material is exceeded, the profile peaks of the workpiece surface flow into the adjacent recesses in the μm range. Compared to the machining by means of rollers, the contact area between the workpiece and the diamond is much smaller. Therefore, plastic cold working with a reduced influence of force can take place.

Perfect Finish for Sophisticated Workpieces

Small, fine and in excellent Baublies quality: these are the new burnishing tools which we have developed especially for filigree in applications. Baublies has optimized their  many years of know-how in diamond burnishing of small precision parts and thin-walled workpieces in a compact form.

Diamond burnishing tools from the Colibri series are always optimally suitable when the peak-to-valley height of filigree workpieces is to be minimized and at the same time the strength is to be increased.

Powerful Compression and Smooth Surfaces

Interchangeable single-roller tools and the Baublies modular tool system achieve a significant increase in the material surface hardness in combination with a very smooth surface. With single-roller burnishing, a hardened roller flattens the surface of the workpiece by contacting it at one single point. In this area of contact the steplessly adjustable roller pressure reaches the yield point of the material. Variable single-roller burnishing tools are flexible adjustable for various contours and can also be used in hard-to-reach places. The rolling unit can be swivelled by 180°.

Extremely Smooth Surfaces in Just Seconds

The best surface quality is well described the main attribute of Baublies multi-roller burnishing tools. Depending on the burnishing task various numbers of hardened rollers are arranged in a cage. The machining times are kept short by using several rollers. During roller burnishing with multi roller tools, a roll off process with kinematics similar to those of a planetary gear result. A taper supports the rollers and provides the contact force for forming the material. The rolling diameter is adjusted by axial shifting of the taper relative to the roller. Therefore, it is  particularly suitable for small and filigree workpiece.
