Sanding method

Furniture and furniture parts manufacturers who proceed their work pieces in sanding lines, face the problem that there is the need to turn their pieces and send them through the line again, if the back side sanding needs to be addressed. This reduces the capacity of the sanding line and causes additional costs.

Therefore many of these users decide to integrate a MB Bottom Sander in their lines. In this way they sand their parts in one pass from top and bottom to be able to transfer them immediately to further processing.
In the basic configuration the Bottom Sander machine series contains a disc system what is a solid basic layout for those customers, who wish an optimized price-performance ratio.

Due to the modular design of this series also other sanding systems, such as a double brush aggregate enhancement, is available. The possibility of different aggregate combinations allows the customer to arrange a machine for his specific application.

A from top working vacuum transport feeds the work pieces secure over all sanding units, which work from the bottom.

In this way the work piece backs have uniformly rounded edges and a perfect surface finish.
