ECOROLL AG Werkzeugtechnik, located in Celle, Germany, specializes in tools for metal surface improvement, including roller burnishing, deep rolling, and combined skive-burnishing. These technologies are used in industries such as automotive, aerospace, and medical technology.
This process creates mirror-finish surfaces, increases hardness, and reduces friction and wear, characterized by short cycle times and complete processing in one setting.
Deep rolling enhances service life and fatigue strength by inducing residual compressive stresses and work hardening in the surface layer, preventing stress corrosion cracks.
Used for hydraulic and pneumatic cylinders, this process reduces friction and wear, enhances cutting speed, and improves surface irregularities.
ECOROLL offers various tools for different applications, including G, R, RD, RAD, RA, RP, RDP, RK, and RKA tools, each designed for specific surface types and machining needs.
These tools are designed for machining cylindrical bores and surfaces, featuring convenient diameter adjustment and high-precision performance.
Used for internal diameters and complex contours, these tools are applicable in deep rolling fillets and rotationally symmetrical surfaces.
ECOROLL's deep rolling tools enhance fatigue strength and surface quality for internal and external fillets and chamfers.
Design versions include through holes with non-feeding or self-feeding cages, and blind holes with non-feeding cages. Rolling lengths range from 100 to 300 mm, with other lengths available upon request. Shank types include Morse taper and Cylindrical Weldon shank.
Suitable for bore tolerances up to class IT8 and metals with tensile strength up to 1400 N/mm² and hardness HRC ≤ 45, achieving surface quality of Rz < 1 µm.
For cylindrical bores, through holes, and blind holes with diameters 201 – 450 mm, featuring circumferential speed up to 250 m/min.
For stepped bores and shafts, eliminating the need for a second tool and requiring minimal lubrication.
For cylindrical outer surfaces with diameters 3 – 160 mm, achieving high surface quality.
For non-cylindrical surfaces, offering high precision performance and short processing time.
Designed for irregular surfaces, featuring short cycle time and modular construction.
Detailed specifications for ECOROLL single roller and hydrostatic tools, suitable for CNC-controlled or conventional lathes.
EG5, EG14, and EG45 series designed for various machining tasks, offering modular construction and minimal lubrication requirements.
HG series capable of roller burnishing and deep rolling complex contours, maintaining constant burnishing force.
Tools offer short cycle times, minimal lubrication needs, and consistent high-quality results.
Instructions on ordering tools, specifying design versions and configurations.
Improves surface layer characteristics, increases fatigue strength, and extends service life.
Induces residual compressive stresses, enhances surface finish, and eliminates additional hardening processes.
Involves plastic deformation below recrystallization temperature, enhancing surface layer strength.
Includes plunge-in and feed processes, suitable for various surface types.
Deep rolling force monitored through spring deflection or hydraulic pressure.
RH, RHA, EF, and FAK tools used for enhancing fatigue strength and surface finish.
Skiving heads and combined skive-burnishing tools used for precision machining of cylinder surfaces.
Designed for processing cylinders, improving circular form and surface quality.
Include floating skiving knife, hydraulic RETRAC® system, and manual roller head adjustment.
Offers solutions for correcting irregularities in large diameter tubes.
FA and HGx-29 tools enhance fatigue strength and surface quality.
Designed for spherical surfaces, achieving high surface quality.
Recommended cutting speeds and feeds for different tool types and applications.
Examples include rotary seal surfaces, fly wheels, ball studs, brake pistons, cam shafts, valve caps, torque converter housings, valves, clutch discs, half pipes, valve housings, and brake drums, each with specific tool usage and process parameters.
Low surface roughness, high surface contact ratio, increased hardness, and wear resistance.
Includes Ra, Rz, R3z, and Rq, each measuring different aspects of surface roughness.
Specifications according to DIN ISO 1302, including roughness value and machining tolerance.
Higher material percentages exhibit better wear behavior, with plateau-like surfaces providing good lubrication.
Improve surface and part quality, enhance fatigue strength, reduce cycle times, and eliminate the need for multiple machines.

How does roller burnishing differ from deep rolling? Some use the term “roller burnishing” to refer to both processes. To clarify for our customers the unique advantages of both processes, ECOROLL prefers to dierentiate deep rolling from roller burnishing. Although the technological means are similar, the goals and results as well as the tools used for each process dier. When the application goal is to improve surface nish and/or increase bearing contact area, ECOROLL recommends roller burnishing. Deep rolling, on the other hand, oers a reliable process for increasing fatigue strength. That deep...
