Long Belt Finishing Machines - LMD3100


About LMD3100

LMD3100 is a long belt finishing machine with higher flexibility on the work of flat surfaces as well as corners or edges of materials.

A wider table of 3100mm with double goose neck (200mm) on the sides enables now the work of higher dimensions.

An even more flexible abrasive belt and more adaptable and ergonomic grinding tools working in counter weight system enable now the work in a wider variety of shapes either for finishing or weld removing.

This machine is ideal for irregular shapes polishing as well as for weld removing. The flexible and adjustable table is useful when, because of the big dimension of the materials to be worked, you cannot move the piece.

With LMD3100 you move the table by motor and use the adaptability of the long belt together with several grinding tools in order to work the areas you need.
