Fineblanking is a metal part blanking process that uses specially designed dies to produce complex parts quickly and efficiently. Though the process itself is similar to stamping, the resulting parts are more akin to those produced via machining.
With fineblanking, a number of intricate features can be produced in a single operation, with edge and surface finishes comparable to machining and none of the severe roll-off and die break that conventional stamping operations produce. Fine blanked parts will have greater accuracy and better feature-to-feature tolerances in their profiles, holes, and other details than conventionally-stamped ones.
Why Choose Fine Blanking Over Stamping or Machining?
If you need complex, small- to medium-sized metal parts in high quantities (tens to hundreds of thousands or more), fineblanking is the fastest, most efficient, and most cost-effective production method available.
High Efficiency Part Production
Perhaps the greatest benefit of fineblanking is that a single stroke of the press is all that is needed to produce a complete-to-print part or near-form blank. With just one stroke, fineblanking can produce:
- Small, intricately-shaped holes (i.e., not just circular holes)
- Narrow slots and projections
- Coining or thinning
- Shallow chamfers
- Counterbores and countersinks
- Bends and offsets
- and other complex features
Fineblanking eliminates the need for additional production processes such as reaming, broaching, edge grinding, countersinking, counter-boring, milling, flattening, and other processes.
Little to No Secondary Processing Required
Though conventional stamping and machining may be less costly, any cost savings are immediately lost due to the need for secondary finishing operations. Fineblanking automatically removes burrs from the burr side of the part and roll from the roll side of the part, and creates a more symmetrical overall look. Fineblanked parts typically require only minor disc grinding.
Exceptional Accuracy & Precision
Fineblanking is an extremely accurate way to produce parts, with tolerances equal to or better than high-precision stamping or machining operations. In general, Petersen Precision can hold feature-to-feature tolerances as low as 0.75 material thickness, depending on the material used; certain materials allow for even tighter tolerances. Our fineblanking processes ensure perfect repeatability from the first piece to the last, even for production runs with quantities in the millions.
The Fine Blanking Experts
Petersen Precision has the experience and the expertise to produce fineblanked parts that match your exact specifications. We are uniquely equipped to take from the design stage through full production.
We offer DFM services to help make your parts faster, easier, and less expensive to produce. Our engineers will work with you, as needed, to optimize your designs for better manufacturability, without altering the overall fit, form, or function of your parts.
All fineblanking dies are designed, built, and serviced in-house to ensure superior precision and quality for your finished parts. Dies are serviced and maintained for the life of your program, whether you need ten thousand parts a year or a million.
Fine Blanking Materials
Petersen Precision works with a wide variety of metals, in coil or strip form. We can produce your fineblanked parts from:
- 300 series stainless steel
- 400 series stainless steel
- Cold rolled steel
- Exotic Alloys
All materials must be stamped in an annealed state; most materials can be hardened after stamping. Contact us to discuss your material requirements.
