High speed rotating face cams machined from Power-Core™ outlast steel

Exact steerage requires dimensionally stable cam tracks with narrow tolerances. Our cams are precision machined from solid blocks of cast Intech Power-Core™ material, offering a longer lasting solution than stainless steel.

In high speed machines Intech Power-Core™ cams exhibit damping behavior which leads to reduced stress peaks. Additionally the high performance plastic cam offers exceptional resistance to wear with limited or no lubrication, which is critical to avoid contamination.

The face cam converts circular motion to linear motion or vice versa, typically it is a disc with a groove cut in its face, in which a cam follower travels. The attached image shows such a cam used in a tableting machine.

In this case the customer required self-lubricating material performance and had experienced constant stress problems using cams machined from plastic materials with low levels of crystallinity, such as Delrin®. However they found that Power-Core™ material, with higher crystallinity levels, can be used to produce a more stable cam that does not suffer stress peaks.

Industries in which our cams have been used include packaging, food processing, printing, as well as stitching machines and other general engineering applications.
