PREWI AGGREGATES
Precision When It Matters Most.
PREWI machining units expand the capabilities of modern machine tools – powerful, versatile and perfectly suited to a wide range of machining applications. For precise results, efficient processes and solutions tailored to your exact requirements.
Machining Units for Precision Machining Applications
Since 2003, PREWI has been developing high-quality machining units for the wood-based materials processing industry. The first units were marketed under the well-established S & P brand name, which remains recognised today. Since then, the product range has been continuously expanded, refined and adapted to meet the demands of modern manufacturing processes.
Whether for sawing, milling, drilling or probing, every PREWI machining unit is a technically advanced, field-proven product. Durability, high-quality workmanship and the use of components from renowned manufacturers ensure reliable performance in day-to-day production.
As a full-service system supplier, PREWI provides machining units and tools from a single source. The range is complemented by expert advice, reliable service and installation support, as well as dedicated project teams for customised solutions.

T 40 / T 41
The Versatile Lock Case Milling Unit
Its robust, offset design and centrally positioned spindle output enable exceptionally deep milling operations while accommodating maximum tool lengths.
Custom Solutions – When Standard Just Isn’t Enough
Not every machining task can be accomplished with a standard machining unit. That’s why PREWI also develops and manufactures customised solutions tailored to the machine, tool, workpiece and production process.
From initial technical consultation and engineering design through to manufacturing, PREWI delivers solutions precisely tailored to each application. Decades of experience in machining unit development, tooling technology and industrial wood-based material processing are incorporated directly into every design.
Custom-Engineered. Precision-Manufactured. Tailored to Your Application.

Tracing Spindles – Precision Machining Along the Workpiece Contour
PREWI tracing spindles enable reliable, contour-guided machining directly on the workpiece. Precise contour tracking compensates for dimensional and positional tolerances during the machining process.
This ensures accurate, consistent and repeatable milling, sawing and other machining operations, even with varying workpiece geometries. Robust construction, high rotational accuracy and a range of tool mounting options make PREWI tracing spindles a versatile solution for continuous industrial use.
