Superfinishing machines for the perfect surface

Supfina offers the right machine for every superfinishing operation, optionally expanded with extensive automation.

Superfinishing

Flexible and universal

Superfinishing is a chip removing machining process. But not one that is comparable to any other. In contrast to the classic lathe turning and grinding methods, there is full surface contact between the tool and the workpiece.

This is precisely the feature that produces the unique characteristics of a perfectly machined surface. This is superfinishing!

Supfina’s throughfeed-finishing machines help to achieve high production rates with minimal work effort, thanks to reduced retooling times and long service lives for the tools.

The Supfina machine series RollerFlex and RollerPro, with their various levels of configuration and automation, offer the right solution for the surface finishing of rolls:

  • Spherical rollers
  • Cylindrical rollers
  • Tapered rollers
  • Piston pins
  • Piston rods
  • Rollers

Ball machining

Superfinishing of spherical components

Whether hydraulic, valve or hip balls, the surface has to resist high stresses and guarantee tightness no matter how different the application.

To achieve this, superfinishing of the surface is necessary. The Supfina machine series LCM TS, Face and the attachment series 291 are designed for this purpose.

  • Valve balls
  • Spherical bearings
  • Hip joint balls
  • Hydraulic tappets
