The FZU/FZP42 machine line features a thermo-symmetrical design that incorporates a centrally-guided Z-slide, resulting in a more dynamic, productive and energy-efficient machine.
Zimmermann Inc.’s FZU/FZP42 machine line offers efficient five-axis portal milling machines for heavy workpiece machining. These machines feature a thermo-symmetrical design that incorporates a centrally-guided Z-slide. This particular construction, as well as the guide layout, is said to increase machine stability, while also saving weight — resulting in a more dynamic, productive and energy-efficient machine.

The idea behind a thermo-symmetrical design is based on the ability to absorb incurring thermal influences, achieved by the design of the machine structure itself. Considering this factor, Zimmermann has designed and arranged the machine structure and drive unit components and guides, as well as other components responsible for accuracy, for all machines in this newly developed portfolio. In this way, the machine structure may expand in directions that are non-critical.
The centrally guided Z-slide of the portal in double-bridge construction has a large cross-section that increases stablity and rigidity. Since there is no possible one-sided temperature rise, accuracy is greatly increased, as well. With this structural design, the machine manufacturer constructively reduces the effects of error-inducing variables to a minimum. Additionally, the thermo-symmetrical design makes it possible to omit complex cooling circuits, which also has a positive impact on cost reduction.
According to the company, high tool weights of up to 40 tons do not pose a problem for the FZU42 system, because the components are not being moved. The movement system, consisting of the portal, Z-slide and milling head, can operate with consistently high dynamics, regardless of the tool weight.
Many job shops start in a garage with a used mill and a manual lathe. The owners of this Utah job shop took a different tack. Along the way to a very successful business, they've debunked a bunch of myths commonly held about job shops.
Shops that machine large aluminum parts don’t have to pay millions of dollars for a machining center just to get the work envelope they need. There is a more affordable alternative, and it’s manufactured in the USA.
