Mineral Wool

With the implementation of climate protection regulations, the requirements for energy efficient building and renovation are increasing. At the same time, the materials used for the insulation of buildings and the necessities for their material properties are changing. Logically, the technologies for processing these materials must also adapt to these conditions.

Leitz tool solutions for the length and crosswise processing of mineral wool products deliver through their high productivity and contribute to environmental protection throughout the entire process chain.

Due to the extremely abrasive properties of rock wool and glass wool, specific tool solutions are required for their machining. Depending on the density and composition of the material to be machined, consistently perfect results must be maintained over long-term use. The challenge in cutting, profiling or boring is to maximize the tool life and performance of the tools used to make the overall process as efficient as possible.

Sizing and cutting with circular knives

Circular knives have the advantage of cutting the material almost without any chips and bringing it to the required size. The different densities of the material are decisive for whether knives with smooth cutting edges or with serrated grinding or discontinuous cutting are used.

Sizing and cutting with circular sawblades

Mineral wool, which has a material density of more than 120 kg/m³, is mainly sized using circular sawblades. However, the “washing out” of the tool body and the resulting rapid breakage of the saw tooth must be avoided. Leitz offers special gullet-area protected circular sawblades for such requirements, which impress with their long tool life, especially in large series production.

Profiling with HW-tipped cutters

High feed rates with perfect cutting quality are the requirements for profile processing of mineral wool products. Leitz tool solutions with HW-tipped cutters make it possible to make the current machining process particularly short and efficient during profiling and to significantly extend the tool life compared to conventional tools.

Drilling

Drilling of holes in mineral wool places the highest demands on the cutting quality of the tools used. The resulting boreholes must be absolutely clean and free of protrusions or residues for optimum functionality of the end product. Leitz offers solutions especially for these demanding machining processes, such as an exchangeable VHM boring head, which is characterized by long tool life and perfect cutting results.
