"In order to achieve the extremely demanding precision for spherical components such as spherical plain bearings and rod ends, we use the modular superfinishing machine LCM TS from Supfina".

Between lower unit costs, smaller batches, maximum flexibility and demands for higher quality requirements – what gives you the best chance of surviving as a supplier in this market? Supfina offers you the solution.

Based on our decades of experience in superfinishing and automation of manufacturing processes, we design solutions that meet your exact requirements. In cooperation with our customers, we develop systems that are tailored to your specified needs. In this way, maximum accuracy and consistent surface quality can be achieved with low unit costs, even for individual components.

Spherical plain bearings and spherical components are used in a wide range of applications. They are installed in many different variants in the aerospace, automotive and agricultural industries. In all areas, these parts are subject to the highest quality requirements, as they must function perfectly despite high loads. Precise machining and manufacturing is therefore indispensable. In addition, long-term process reliability and low cycle times are paramount, adhering to the cost-efficient production of the required quantities in these ever-growing industries.

Together with you, our team of forward-thinking engineers and designers develop cutting-edge technology ensuring long-term success in the constantly evolving manufacturing world. Through early involvement, and during all phases of product development, building, installation and service, we support you with regard to surface criteria, process technology and prototyping.

Focus on Perfect Solutions

Innovative automation solutions also allow full flexibility when integrating new processes into existing production structures. From the seamless integration of individual systems to robot-guided machining processes, all variants are possible. We always have your perfect solution in mind.

Make Your Production Smart

Have you considered… Increasing added value through integrated sensors and smart data analysis? Incorporating intelligent production through networking with the strategic communication of the entire operation? Increasing profitability by optimizing ordering processes, material flows and production? Improving Overall Equipment Effectiveness (OEE) through better planning of service and maintenance work? If so, we will be happy to support you in this with our SQS products and the experience we have accrued over many years in a plethora of different areas.

Protect Resources

Reduced friction and low weight of the individual components are a prerequisite for low fuel and power consumption and thus important features for the powertrain, especially with alternative drives. A long service life and reduced noise emissions, on the other hand, underline our customers' quality requirements. For example, the functional surfaces of many moving parts influence energy consumption and thus the decisive mileage range. With our decades of experience, we support you in component design and product development.

Your Advantages

Improvement in surface roughness

Plateau-like surface structure increases the material contact ratio to over 90%.

Improvement of the microgeometry with regard to roundness and waviness

Optimization of the tribological and emergency running properties through cross-hatched machining tracks.
