STR 8 Roller Burnishing Tool for holes uses the principle of plastic surface deformation of metal at normal temperature to smooth the surface of the workpiece, change the surface structure, mechanical characteristics and tolerance.
Tooling is a method of chipless machining, which utilizes the principle of mechanical extrusion to produce a smooth, mirror-like surface of metal.
A certain amount of pressure is applied to the surface of the workpiece by a roller-rolling tool, so that plastic flow of metal occurs in the surface layer.
It fills the existing depressions, and reduces the roughness of the surface of the workpiece.
Due to the plastic deformation of the metal surface, the surface micro-structure is hardened, the grain is refined to form a compact fibrous structure, and a compressive stress layer is formed.
The hardness, strength, wear resistance, corrosion resistance and stability of the workpiece surface are improved.
This method can be used for both surface finishing and hardening, which cannot be achieved by grinding and turning.
Maximum hardness of the workpiece to be machined 40 LDC
Rolling hardens the surface in a short time, while improving surface roughness and increasing part life due to compressive residual stresses.
The diameter of the workpiece is changed only by the size of the roller indentations into the workpiece surface.
To ensure the required machining tolerances, it is important to maintain the allowance prior to the machining process to account for the diameter change.
The accuracy of the prior machining process directly affects the size after rolling.
The diameter variation depends on the material, hardness and rollers.
Two to three experimental passes should be made to obtain the best machining parameters before inline machining a batch of parts.
The blind hole roller tool can burnish both through and blind holes.
Hole diameters to be machined: 6-200 mm - the standard tool range. Larger diameters can be produced to order.
Larger diameters can be produced on customer's request.
Attention!!!
! 1 TOOL WORKS ONLY 1 DIAMETER !
The production costs you save:
- Low burnishing costs
- Pre-machining and roller burnishing on one machine
- Reduces the cost of an additional machine and reduces labor and time required for re-setting, clamping and re-basing of the workpiece
- One set-up, one pass
- Very short machining time
- No chips or other waste
- Low energy consumption
