Wood remains a key material in modern foundry pattern making. It is easy to machine, is available and is suitable for repeated impressions. Precise milling tools are required to achieve high dimensional accuracy. With the Wood series, Lukas-Erzett offers carbide rasp cutters that are tailored to the machining of wood molds.
The fine-grained carbide tools are available in various shapes and, according to the manufacturer, enable controlled material removal with smooth running. Their special cutting edge geometry ensures high removal rates and fast feed rates, which reduces machining times. The tools are suitable for both CNC machining and freehand work.
Consistent results and reproducible tolerances
Dimensional accuracy is crucial in foundry pattern making, as any deviation is directly transferred to the casting mold. The wood milling cutters from Lukas-Erzett are designed to enable controlled, low-vibration guidance and thus produce precise contours, transitions and radii. Chip splitters in the toothing reduce the cutting forces and support consistent results even at high feed rates.
Thanks to the precision-fit steel shank, the milling tools run backlash-free in the machine, which improves reproducibility and reduces rejects. This allows foundry models to be produced with smooth surfaces and clear edges - a particular advantage for components with tight tolerances, for example in mechanical engineering.
Tool combinations for efficient processes
In addition to the Wood series burrs, the Lukas-Erzett range also includes sanding solutions for post-processing, such as flap wheels, sanding belts and mounted points. In combination, these can be used to efficiently achieve both fast stock removal and a fine surface finish.
The combination of carbide cutters and flexible grinding tools enables a continuous machining process from modelling to finishing - with the aim of minimizing rework and increasing process reliability in foundry pattern making.
