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.

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.
