YDB can easily work many different materials with hardness up to 60/65 HRC. YDB can pass through the workpiece surface like a normal chip removal tool. It must be used with coolant. Obtained finishing depends on some variables such as the kind of material, hardness, finishing before burnishing, working speed and pressure, but generally values from 0.3 to 0.08 can be achived. YDB models depending on the application and customized models can be supplied.
Different than other single roll tools, GRV can flex in 2 directions.
* One tool can roller-burnish both internal & external diameters at a single setup
* One tool can roller-burnish both internal & external faces at a single setup
* Grooves on faces or diameters can be roller-burnished
Tool body has a spring inside which creates the burnishing force . BSBT is different than other single roll tools because the free angle of the roller can be adjusted by the operator. This way burnishing pressure can be changed while the burnishing force is constant.
Tools are engineered to use on machining centers. • Dia adjustment range is wide.
• Delivered with 3 different arms :
1. Arm for workpieces between Ø150 ~Ø190
2. Arm for workpieces between Ø180 ~Ø250
3. Arm for workpieces between Ø240 ~Ø370
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. Typical sealing surfaces in parts include: face seats, angular or tapered seats of internal or external construction.

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.
The FH is a flexible abrasive tool ideal for lapping, deburring cylinders, hydraulic elements, aluminum injection parts, automotive, precision parts, etc. Tool composed of small and independent unbreakable balls tied to the center by nylon strips. It is self-centering and adjustable, so you can adapt it to any unevenness of the surface of the hole to work. Reduces the values of RA, but keeping Rpk Rk and Vo and keeps Rvk and volume. Achieving a perfect polished. You can attach it, in manual and automatic machine drills. This tool is ideal for cylinders, connecting rods, crankshafts tooling.
