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.

Why do many people use roller burnishing tools to burnish?

Roller burnishing improves surface finish by removing scratches, tool marks and pits and induces beneficial compressive surface residual stresses. Consequently, corrosion performance is improved because corrosion products and residues cannot be entrapped. In this process known as low – plastic grinding, the rollers move only once on the surface, resulting in residual stresses and minimal plastic deformation. Internal cylindrical surfaces also are burnished by a similar process, called ballizing or ball burnishing. In this process, a smooth ball is pushed through the length of the hole.

Benefits of RBT Roller Burnishing Tools

Roller burnishing is used to improve the mechanical properties of surfaces as well as their surface finish. It can be used alone or in combination with other processing techniques such as grinding, honing, and lapping. The equipment can be installed on various CNC machine tools to improve productivity and consistency. All types of metals can be roller burnished.


Roller burnishing is typically used on hydraulic system components, seals, valves, spindles, and fillets on shafts.


Multi-roller burnishing tool: Impressive advantages

Three types of RBT burnishing tools

Roller burnishing has long been used on a wide variety of automotive and heavy equipment components (construction, agricultural, mining and so on), including piston and connecting rod bores, brake system components, transmission parts and torque converter hubs.

Burnishing tools are now widely used in non-automotive applications to achieve a variety of benefits: to create a better, more durable seal surface; Increased wear life; Reduce friction and noise level of running parts; And enhance the appearance; to improve wear life; to reduce friction and noise levels in running parts; and to enhance cosmetic appearance. Examples include valves, pistons for hydraulic or pneumatic cylinders, lawn and garden equipment components, shafts for pumps, shafts running in bushings, bearing bores, and plumbing fixtures.

RBT Roller Burnishing Tools are used for the aim of burnishing the cylindrical holes that have an open and closed end. The tools provide as well as surface hardness and calibration (measurement accuracy) beside of burnishing.  According to the process type, there are three types of RBT burnishing tools:

RBT roller burnishing tool applications

Blind Hole machine-feeding

These burnishing tools process stepped or fully closed holes up to end. While the tools process the workpiece, the machine provides feeding speed which is needed.

Through Hole machine-feeding

These burnishing tools process the holes with open ends. The machine provides the required feed speed when the tool is working on the workpiece.The tool or the workpiece can be turned with the speed of max. 250 m/min. The feeding speed of the machine can range from 0,05 mm/rev. to 0,3 mm/rev. for per roller.

Through Hole self-feeding

These burnishing tools process the holes with open ends. The tools provide own feeding speed which is needed while it is processing the workpiece. Feeding occurs free from the machine.
