<strong>SUPERFINISH</strong><br />
<strong>Finishing</strong> <strong>of</strong> <strong>Cylindrical</strong> <strong>and</strong> <strong>Conical</strong> <strong>Rollers</strong><br />
470<br />
Technical specifications:<br />
Workpiece diameter with<br />
T<strong>and</strong>em transport rolls: 1.5–5mm<br />
Adjustable roll inclination: 4–100mm<br />
Permanent roll inclination: 4–200mm<br />
Advantages<br />
● Optimum improvement <strong>of</strong><br />
surface roughness, concentricity<br />
<strong>and</strong> surface bearing ratio<br />
● Generates plateau honed surfaces<br />
to comply with DIN 4776 E<br />
● Versatile applications for all rotationally<br />
symmetrical workpieces<br />
● Generates special shapes<br />
e.g. antifriction rollers<br />
● Rapid retooling<br />
● Powerful pneumatic oscillator<br />
● Mass-compensated oscillator drive<br />
● High rates <strong>of</strong> throughput<br />
comparable to centreless grinding<br />
The machining process<br />

The results<br />
surface roughness Rz: 0.5µm<br />
surface line shape: 1 to 2µm convex<br />
concentricity: 0.5µm<br />
stock removal: 3 to 4µm in ∅<br />
output: 4 to 6m/min<br />
CMK: 1.33<br />

Generation <strong>of</strong> special shapes:<br />
In some specific applications e.g. in the<br />
antifriction roller bearing industry,<br />
superfinishing is used to create special<br />
shapes. Examples <strong>of</strong> these are cylindrical<br />
convex <strong>and</strong> fully convex cylinder<br />
<strong>and</strong> conical rollers.<br />
Microscopic surface structure:<br />
The surface structure is equivalent to<br />
that <strong>of</strong> a honed surface. The machining<br />
pattern assists in the creation <strong>of</strong> a lubricating<br />
surface.<br />
surface roughness Ra: 0.07µm<br />
surface line shape: 2µm convex<br />
concentricity: 0.7µm (Filter 1–500)<br />
stock removal: 5µm in ∅<br />
output: 400 rolls/min<br />
CMK: 1.33
