Friction Optimization for Performance and CO2 Reduction

Smooth, isotropic surface structures are essential in the automotive sector to reduce friction, minimize wear, and extend the lifespan of components. OTEC technologies excel particularly in engines and drivetrains. These precise processes enable the use of low-viscosity lubricants, actively contributing to CO2 reduction.

Your benefits at a glance:

  • Reduced friction and increased efficiency
  • Lower wear and extended component lifespan
  • Achieved through low pressures and induced compressive residual stresses
  • Enhanced support for modern lubricant concepts
     

Efficiency for E-Mobility and Future-Oriented Applications

With a focus on e-mobility, OTEC actively shapes the future. For example, processing transmission components using stream finishing technology significantly increases efficiency, resulting in reduced range losses in electric vehicles. Additionally, specialized applications like processing rotor shafts, steering worms, or hairpins for electric motors provide valuable optimization contributions.

  • Rotor shafts benefit from smoothed running surfaces, increasing the durability of sealing systems.
  • Steering worms are optimized for better driving behavior and reduced NVH (Noise, Vibration, Harshness).
  • Hairpins for electric motors are processed with absolute precision to prevent insulation damage.
  • Gear teeth experience increased load capacity and improved efficiency.

Eco-Friendly Technologies for Series Production

OTEC relies on environmentally friendly processes like mass finishing, free from harmful chemicals. This eliminates high procurement and disposal costs for chemicals. The machines are ideal for series production and can be individually configured to meet specific requirements.

Why OTEC?

  • Combination of processes like smoothing and deburring in a single step
  • Reduction of process steps and increased efficiency
  • Sustainable and cost-effective Solutions

 

Perfect Processing for the Highest Standards

From gears to camshafts, OTEC technologies deliver flawless surfaces that meet the highest quality standards. Whether preparing for protective coatings like PVD or DLC, or rounding and polishing wire-contacting tools, OTEC offers the perfect solution.

This includes processing tools such as:

  • Straightening and bending rolls
  • Cutting and bending punches
  • Handling grippers
  • Setting tools
  • Forming tools and dies

Smoothing | Polishing

Cam pieces, transmission parts, differential/hypoid gears, connecting rods, steering components, steering gear spindles, actuators

The OTEC Mass Finishing Process creates plateau-like surfaces with a high material bearing ratio, providing optimal conditions for sliding and friction surfaces. By reducing peak values to Rpk <0.1 µm, wear is minimized, and the lifespan of components like gears, camshafts, or pistons is extended. Simultaneously, noise (NVH) is reduced. This precise surface treatment impresses with reduced friction, wear, and leakage, making it particularly efficient and economical for the automotive industry.

 

Deburring | Rounding

Oil control discs (shims) in shock absorbers, gears, sprockets

With OTEC Mass Finishing Machines, workpieces can be efficiently deburred and precisely rounded – all in a single process. This innovative surface treatment improves handling and assembly, reduces the risk of injury during installation, and ensures visually and haptically superior components. Whether bulk or individual parts, OTEC offers customized solutions for maximum precision and efficiency.

 

Other Applications

3D printing, racing, motorsports (pistons, piston rings, injection systems, pump parts, visible parts, logos, decorative elements, etc.), e-drives, piston pins

OTEC systems revolutionize surface finishing with process times up to 17 times shorter compared to conventional methods like trough vibration or chemically accelerated mass finishing. Efficient, process-secure, and cost-saving – OTEC avoids the use of environmentally harmful and dangerous acids. These sustainable finishing processes offer a stable and innovative solution for the highest demands.
