Combination unitCombination units in wide belt sanders consist of a sanding belt unit in which two contact sanding tools are combined. Usually, these are combinations of a sanding roller aggregate and a sanding pad aggregate, but the combination of two sanding rollers (VIET KRR) also occurs. Combined sanding aggregates are mainly used in the crafts sector. Frequently changing sanding tasks can be handled with a compact machine, there is no need to purchase a large machine with many sanding aggregates, this saves space and keeps the purchase costs lower. Machines with only one combination unit are also called combination machines. ConstructionThe sanding roller- sanding pad- combination unit has essentially the same construction as the sanding pad aggregate. However, the first deflection roller is replaced by a sanding roller.
