Small Parts Incorporated, a precision metal stampings provider based in Logansport, Indiana, recently purchased two unitised-frame, two-point, direct drive, model DSF-N2 Aida servo presses. The presses have quickly realised several benefits on jobs moved from the company’s mechanical presses to its new servo presses, including increased strokes per minute (SPM) and up-time per run.

After modifying an existing automotive progressive die to run on Small Parts Inc’s new 110 ton Aida servo press, the company achieved burr reduction and less part distortion, which it attributes to complete programmability throughout the entire stroke of the servo press, decreasing parts failing post-sort. Moving this die from a mechanical to a servo press also shortened the feed length. These combined advantages resulted in a scrap reduction of approximately 30% on this automotive part.

Small Parts is also achieving die-life improvements. The sharp edge profiles on a non-automotive die were breaking or wearing down multiple times while stamping an order on a mechanical press. Switching this die to the DSF-N2 Aida servo press has already reduced die maintenance by 50%, which the company expects will increase to 60-70% when further tooling improvements are complete. As another example, making new cutting inserts to reduce the cutting clearance for an existing automotive die immediately yielded a 55% increase in die life when moved from a mechanical press to the new servo press.

The addition of the two Aida servo presses has also expanded Small Parts’ quote capabilities. Having seen the improvement and what is actually achievable first-hand, the company now has the confidence to quote servo-press jobs that would have been troublesome to stamp on mechanical presses.
