What should be noted before roller burnishing tools?

How to select roller burnishing tool, Roller burnishing tool attention points, Roller burnishing tool model, Buy roller burnishing tool, Roller burnishing tool problem

Roller burnishing tools of different models should be analyzed first.

First determine the following situations:

Is this part suitable for roller burnishing tool?

What is the workpiece material to be rolled and how hard is it?

How thick is the wall of the part that needs to be rolled? Can it bear rolling?

Is the part that needs to be rolled on the inside hole or the outside hole?

Is the part that needs to be rolled is blind hole or through hole?



These problems need to be determined before the corresponding roller burnishing tool can be selected. If you don’t know how to choose the model, please contact us to help you.

Advantages and disadvantages of roller burnishing process

Roller burnishing process is a kind of non-chip machining, which exerts certain pressure on the workpiece surface through certain forms of roller burnishing tools. The plastic deformation of metal is used to smooth the uneven surface of workpiece at normal temperature, so as to change the surface structure, mechanical properties, shape and size. Therefore, this method can achieve two purposes of finishing and strengthening at the same time.

Advantages of roller burnishing pressure:

After the surface of the metal workpiece is rolled and processed, the hardness of the workpiece surface is strengthened and the yield point is increased.

The performance, fatigue strength, wear resistance and corrosion resistance of workpiece have been improved obviously.

The roller burnishing process is easy to master, and can be processed by ordinary drilling machine. Ordinary operators can process the mirror precision, micron precision parts!

The comprehensive cost of roller burnishing tool is low, which is 10-100 times lower than the cost of grinding machine, quilting machine and ultrasonic rolling.


The deficiency in roller burnishing process:

The surface of the workpiece will be hardened by rolling, and there is obvious stratification between this layer and the inner material, which is easy to cause the surface to fall off.

The rigidity of roller burnishing tool is large, which damages the guide rail of the transmission mechanism of the machine tool and seriously damages the precision and life of the machine tool.

It can not satisfy the processing of rigid parts such as thin-walled pipe fittings.

Advantages of roller burnishing


It is safe, convenient and accurate to control precision.

Roller burnishing tools advantages are:

  • 1. Improve the surface roughness, and the roughness can basically reach the Ra less than 0.08um.
  • 2. Correction of roundness, the ellipticity can be less than 0.01mm.
  • 3. Improve the hardness of the surface to eliminate the deformation of the force and increase the hardness of HV to 40.
  • 4. After processing, the residual stress layer and fatigue strength increased by 30%.
  • 5. Improve the quality, reduce wear, and prolong the service life of the parts, but the processing cost of the parts is reduced.

Roller burnishing tool application advantages – The effect after burnishing


High efficiency – a few seconds can process the surface to the desired surface precision, the efficiency is 5-20 times of grinding and 10-50 times more than the turning.

High quality – the mirror accuracy of the first step in the realization of Ra0.05-0.1um; The surface is extruded and hardened, wear resistance and fatigue strength are improved. The dimensional precision can be stable for a long time.

Economy – no need for large equipment capital, land, power consumption, waste disposal and other inputs; You don’t need a professional mechanic.

Convenient – can be installed in any rotation and feed equipment, without professional training can process the burnishing precision.

Environmental protection – no chip (protection), low energy consumption.

Safety – no cutting tool without cutting edge.

What is the process of Roller Burnishing and its advantages?

What’s the processing principle of roller burnishing tools?

Schematic representation of  burnishing process.

The roller burnishing tools works like a road roller flattening the uneven road.
Roller burnishing tool is to use very smooth roller rolling by processing the surface of the metal, the workpiece performance high extrusion convex parts to dips, so that the machining surface smooth as a mirror effect, this is a kind of plastic processing.
The surface roughness of workpiece is up from Ry1.6-3.2 um to Ry0.1-0.2 um, and improve the processing surface hardness, wear resistance, corrosion resistance, sealing, etc., to eliminate early wear, these have the advantage of machining cannot be replaced.
The rolling tool has a fine tuning device. The adjustment coefficient of each small grid is 0.0025mm, and the total adjustment range is 0.3mm-0.4mm. Therefore, the precision of the processed dimension is also improved accordingly.

The control method of roller burnishing tools

1. Measuring the burnishing tool’s diameter with micrometer.
2. Push the calibrated set to the handle and rotate it at the same time, adjust the diameter of the tool, reduce the left rotation, and increase the right rotation, each scale value is 0.0025mm.
3. When the diameter is adjusted, release the aluminum shell and automatically lock the diameter.
4. When machining blind holes and step holes, the bottom is about 0.5mm-1.0mm cannot be machined. The needle can lightly touch the bottom of the hole.
