Diamond Burnishing Tools Functions: The workpiece that passes through the diamond rolling will get a flat surface with high precision and high strength. When force over the yield point of material, then abnormal peak on the workpiece will be flowed into the adjacent depression with μm as the unit. Compare with roller pin burnishing, Diamond Burnishing Tools has the smaller contact surface, so that in cold forming and less force process situation, RBT strongly recommends using Diamond Burnishing Tools.

Application advantages – The effect after roller burnishing

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.

We are Manufacturer, Exporter, Supplier and Trader of Roller Burnishing Tools. Offered to the customers is a high quality range of Roller Burnishing Tool as per their specific requirements.

Why is rolling technology used so widely in precision machining?

The roller burnishing process is a kind of non-chip processing, and the whole process can be accomplished by applying pressure to the surface of the workpiece by a certain form of rolling tool. Roller burnishing tool is at room temperature using the principle of the metal plastic deformation, rolling flat surface uneven places, to change the surface structure, mechanical properties, shape and size to achieve the effect. Therefore, this method can achieve smooth processing and strengthen two purposes at the same time. The surface strength of metal workpiece is strengthened after surface rolling, and the performance of workpiece, fatigue strength, abrasion resistance and corrosion resistance are obviously improved. After rolling, the hardness of the workpiece can be increased by 15 ~ 30%, while the wear resistance increases by 15%.

Rolling processing can increase surface roughness from Ra6.3 to Ra2.4 ~ Ra0.2. And there is a high production efficiency, some of which can be completed in a few minutes or seconds.

Rolling process can solve some key problems which are not easy to be realized. For example, the machining of a large cylinder block. At the same time, it is also suitable for the finishing machining of special holes or the finishing process of some special materials.

Rolling process is widely used in all large, medium and small factories. In terms of processing quality, production efficiency, production cost and other aspects, roller burnishing process is a superior processing method. In some respects, it can completely replace fine grinding, grinding and honing.

At present, the processing method of the rolling tool by external force can be divided into three types: mechanical, rolling and spring.

According to the processing nature, it can be divided into light finishing and intensive processing.

The roller burnishing tool has the advantages that the machining center does not have. Because the roller burnishing tool can be simple and low cost to carry out the ultra-precision machining of parts. It has been widely used in the automotive industry, such as precision machinery, chemical and household appliances.

What are the performance of the rolling tool products?

Roller burnishing tools, extruding machine, extruding tool, skiving and roller burnishing tool, superfine burnishing rolling head is a special tool for machining holes and shaft parts with no cutting rolling principle.

The surface of the metal surface has a plastic deformation, so that the workpiece reaches the mirror.

The precision of workpiece dimension is guaranteed, and the wear resistance, corrosion resistance and fatigue resistance are obviously improved.

Burnishing rollers have been widely used in aviation, automobile, motorcycle, hydraulic pneumatic and electromechanical industries.

We have steadily improved the quality and efficiency of our products, and have been well received by our customers with high precision and reasonable price.

Product performance

After rough machining of the workpiece, the surface roughness can be reduced to ra0.2um — 0.05um, from around the Ra6.3um.
With mechanical fine tuning device, the deviation control is very accurate (within 5/1000mm), and the mass production size is the same. Through hole, blind hole, taper hole, outer cone, hole end face, step shaft can be processed.
After rolling, the hardness of the working surface can be increased by 40HV, which improves the fatigue resistance.
This tool is small in size and easy to operate, and has low maintenance cost in the long term (parts with wear and tear can be replaced).
It can be used in cars, boring, drilling, milling, CNC machining centers and special production lines, replacing and better than traditional grinding, honing, grinding and other processes.
