RaceFlex

Flexibility for small-scale production

The Supfina RaceFlex can consistently produce rolling bearing races of the highest quality with maximum adaptability, even for prototypes or small-scale production.

A combination of up to four different superfinishing units allows almost limitless flexibility

  • The greatest possible flexibility when machining any raceway geometries
  • The highest quality is easily achieved, even for small batches and single parts
  • Creation of a surface with a high load-bearing capacity and good lubricating properties
  • Improved tool life
  • Ideal for small and medium batches
  • Production flexibility makes it a sound investment

RacePro

Superfinishing in mega format

Even the largest rolling bearing rings require superfinishing of the raceways to withstand the high stresses. The Supfina RacePro is specially designed for the flexible superfinishing of large rings. The design of the machine allows loading by overhead crane or by roller conveyor from the front and rear.

The inner and outer rings of large rolling bearings are required in a wide variety of applications, such as:

  • Wind turbines
  • Cranes
  • Helicopters

Supfina solutions for raceway machining

  • Automatic loading and unloading
  • Multi-step process with automatic sequence
  • Stone and tape machining can be combined
  • Minimized loading times
  • Set-up times < 15 minutes
  • Optimum accessibility
  • State-of-the-art controler system with a technology memory

Superfinishing of raceways with stone

The self-centering workpiece fixture and the oscillating unit specially designed by Supfina ensure maximum precision and outstanding durability.

Two machining stations and two stations for loading and unloading are interconnected via a rotary table, ensuring minimum non-productive times and maximum process reliability.

The processing stations can be used for pre-finishing and finishing or, after finishing, e.g. for coil processing.

The Supfina RaceFlex is made for superfinishing of ball and roller bearings inner and outer rings.

  • The greatest possible flexibility when machining any raceway geometries
  • The highest quality is easily achieved, even for small batches and single parts
  • Creation of a surface with a high load-bearing capacity and good lubricating properties
  • Improved tool life
  • Quick setup
  • Few spare parts
  • Ideal for small and medium batches
  • Production flexibility makes it a sound investment

The highest productivity can be reached through robot-assisted loading and unloading.

The easily accessible work area can be equipped with various machining options.

The RaceFlex can be loaded from above with a crane or gantry loader as well as from the front and rear, manually or by automation.
