Definitions
- the invention relates to a roller burnishing tool for machining a workpiece surface according to the independent claim.
- the invention lies in the technical field of roller burnishing of a workpiece surface.
- a defined surface structure, surface quality or surface geometry is achieved by rolling the roller burnishing tool on the workpiece surface to be machined with a predetermined contact pressure, the workpiece surface to be machined undergoing a plastic deformation.
- the plastic deformation can also include machining and in particular consist of roughening the surface and at the same time blunting the roughened surface.
- One goal of such surface treatments is, for example, to improve the wettability of the machined surface of the workpiece.
- a functionally improved roller burnishing tool is known from DE 10 2017 213 045 A1.
- machining surfaces in particular to create a structured surface (e.g. micro-groove structure, trapezoidal structure, etc.)
- a structured surface e.g. micro-groove structure, trapezoidal structure, etc.
- the invention is based on the object of providing a roller burnishing tool which enables workpieces to be machined well at a high machining speed.
- the invention comprises a roller burnishing tool with a base body with at least one radially adjustable roller holder. At least one roller burnishing roller is rotatably arranged on each roller holder.
- the at least one roller burnishing roller has an outer surface with a rough working section with a predetermined surface roughness.
- the rough working section allows rolling machining of a workpiece with high machining quality and speed.
- the surface roughness of the working section is in the range from 2 pm to 400 pm, in particular in the range from 5 pm to 100 pm.
- the surface roughness is the mean value of the surface roughness of the working section measured with a perthometer (e.g. stylus method).
- the working section comprises a diamond material.
- the diamond material can consist of small diamond particles that are applied to the work surface.
- the diamond material is particularly preferably arranged in a solder mass.
- the solder mass is a metallic alloy with sufficient hardness to hold the diamond particles in place.
- the working section comprises a solid carbide material. With solid carbide materials, hard materials are held together as small particles in a metal matrix.
- the solid carbide material is designed in such a way that the roughness was generated by means of a laser.
- the solid carbide material is designed in such a way that the roughness was generated by means of grinding. Grinding includes any machining until the predetermined roughness is achieved.
- the solid carbide material is designed in such a way that the roughness was generated by means of coating.
- a coating is applied in accordance with the desired roughness.
- Another aspect of the invention relates to a method for producing a roller burnishing roller, comprising the following steps:
- Fig. 2 is a view of a partial section through a rolling roller for the
- FIG. 1 shows a perspective illustration of a roller burnishing tool 1 for machining a workpiece surface, in particular for roughening or blunting a roughened workpiece surface.
- the roller burnishing tool 1 has a base body 12 with a tool section 121 and a fastening section 122 for arrangement in a rotating drive tool (not shown).
- Each roller holder 2 comprises a receptacle for roller burnishing rollers 3, which each rotate about their own axes of rotation which are parallel to the base body axis A-A.
- a roller burnishing roller 3 is rotatably arranged on each roller holder 2.
- each or every second roller burnishing roller 3 has an outer surface with a rough working section (see FIG. 4) with a pre-determined surface roughness in order to enable roller processing of a workpiece with high processing quality and speed.
- the rolling roller 3 arranged in the roller holder 2 is shown in detail in FIG. 2, the outer surface having a rough working section 4 with a roughness in the range from 2 ⁇ m to 400 ⁇ m. The roughness is illustrated by the dotted line.
- the working section 4 comprises a diamond material.
- the diamond particles are arranged in a solder mass, on the one hand to hold firmly to the roller burnishing roller 3 and, on the other hand, to ensure good roughness and high hardness of the surface.
- the working section 4 comprises a solid carbide material, which is most easily realized in that the entire burnishing roller 3 consists of a single solid carbide material.
- the solid carbide material is designed in such a way that the roughness was generated by means of a laser.
- a laser is used to process the surface of the working section.
- the surface treatment provides that the laser radiation penetrates the material only in the area of the predetermined surface roughness.
- the solid carbide material is designed in such a way that the roughness was generated by grinding. When grinding, the material is removed in such a way that the roughness depth described above is achieved.
- the last example provides that the solid carbide material is designed in such a way that the roughness was generated by means of coating. Rough metal alloys can be applied here to create the desired depth of roughness.
