accurapuls-system of peening - short history

The company KWL was established in 1995 and started as sub-supplier for various industries like ship building, tool manufacturing, and mechanical engineering.
One year after start-up, KWL launched the first peening hardware to replace the manual polishing procedure and started the development of an independent CAM-Software to improve the accuracy of peening patterns.
After some years of research and development the accurapuls-system of peening is the first product line, which has exceptional advantages besides surface refinement.
The accurapuls-system of peening improves the roughness of the surface, increases significantly the hardness of the surface layer and inherent compressive stress can be induced into depth of 10/15 mm.
This unique process and the related fields of applications led to the realignment of the company, which is reflected in the marketing of our first product line.

	Replacement of manual polishing
	The accurapuls-system of peening can replace in most of the cases the manual and cost intensive process of polishing. The total cycle time can be reduced significantly, surface rouhgness of less than 0,3 µm can be achieved, while total reproducibility, true to size and security of operation are guaranteed.
	Higher savings through longer lifetime
	Mechanical components and tools perform much longer after treatment with the accurapuls-system of peening. Reasons are the induced inherent compressive stress, which leads to higher hardness of the surface layer combined with the CNC-polished surface. Secondary costs for unplanned down times, spare tools and parts can be minimized by the use of the accurapuls-system of peening.
	Low complexity of integration
	The accurapuls-system of peening - compared to other technologies - is easy to integrate into the existing workflow.
	Increased process safety and stability
	Specifically developed accurapuls-CAM-Software assures absolute reproducibility and sound operations.

The process of peening is based on the mechanism of
moving a coil electromagnetically. Due to the current
flow the moving coil creates a force (Lorenz-force),
which acts in direction of the coil.
This force is proportional to the induced current and
it‘s effective direction follows the current flow direction.
Mechanical vibration can be generated through
electromagnetic oscillation, by using an AC-power-system.
