Standard radius is R2.5 mm. Roller disc with special radius is available.
Shank with different inclination is available.
Diameter of roller disc is Ø85 mm.
- Suitable for metals (steel, aluminium, copper etc) with tensile strength up to 1400N/mm2 and max. hardness of HRC45.
- Roller head is flexible, because the tool is equipted with a spring.
- For use with either CNC-controlled or conventional lathes.
- Can be used on interrupted surface. Thanks to preload system.
- Achievable surface quality min. Ra0.02 μm.
- Unrestricted roller face for roller burnishing shoulders and other edges.
- Roller can rotate in either direction.
SKUV30 can apply 10KN of pressure with 90° shank and over 5KN of pressure with 45° inclined shank with an extremely long life and reliability of both the roll and the internal mechanism.
Improvements of the mechanical resistance from the compression residual surface stresses include :
- Increase of surface hardness.
- Lower surface Ra.
- Elimination of stress factors, corrosion, cracks.
- Increased corrosion resistance.
- Elimination of working signs, scratches, porosity.
- Less Friction & Less noise levels.
Angular roller burnishing tools are designed to burnish conical sections with uniform tapers which are symmetrical with the axis of the workpiece. These surfaces are generally sealing surfaces, and require high quality finishes to control leakage. Roller burnishing of conical surfaces is much faster and less expensive than grinding and honning, and eliminates problems with embedded abrasive which can wear out the sealing element. Typical sealing surfaces in parts include: face seats, angular or tapered seats of internal or external construction. YAMATO ROBUTO® Tools are designed with tapered rolls for true planetary rolling action to prevent skidding effect and produce a superior burnished surface.

Flat Face roller burnishing tools are designed to burnish circular faces which are symmetrical with the axis of the workpiece. These surfaces are generally sealing surfaces, and require high quality finishes to control leakage. Roller burnishing of flat surfaces is much faster and less expensive than grinding and honning, and eliminates problems with embedded abrasive which can wear out the sealing element.

External diameters miniature Roller Burrnishing Tools for Swiss Lathes. Their short length allows them to be used on the reduced spaces in Swiss Lathes. With MICROMOD all the working can be done directly on the CNC machine avoiding the high cost and waste of time for secondary workings. The tools shown are examples, we can do a full customization to meet customer needs. (even shorter than the ones shown). Total length out of the chuck" is only 39 mm. and the tool body diameter is only Ø38 mm. This dimensions are 95 mm and Ø54 mm. respectively on standard Roller Burnishing Tools

Seating rings are expanded by using the Valve Seat Expander. During the operation tool rotates and taper inside the tool comes out. This action enlarges the tool diameter and expands seat ring diameter. At the end of the tapers travel expansion is completely round and absolutely tight. Since valves differ in their series and the seating rings sometimes have somewhat different dimensions, the expansion ranges of the expanders have not been stated. Therefore, we kindly request that you supply us with exact details, including dimensional sketches or drawings, when enquiring or ordering.
Compensating Tool (CMID) with pressure control unit produces excellent results. When part size varies and primary requirement is surface finish.
Different from standard Roller Burnishing Tools, Compensating Tool can adjust its diameter automatically for small diameter change ratios.
