Houfek Duplex pudselinie over/underpudser 910 – 1100 – 1350 mm
Houfek Duplex pudselinie over/underpudser:
910 – 1100 – 1350 mm
Duplex is highly efficient wild-belt grinder designed for double sided grinding of mostly board materials. The construction of Duplex is based on Buldog series and the application of double sided grinding increases the work productivity. The permanent desk height enables to use the Duplex in technological lines. The surface grinding quality and high level of automation ranks the machine in the highest class
