Multi-saw disc saw TT-400 type designed for cutting medium-sized timber of diameter up to 380 mm. The machine is produced in different options depending on the power of the saw spindle engines installed. It provides obtaining the required efficiency depending on the company needs. Installing engines equipped with saw spindles in pairs on two independent plates allows very fast change of the thickness of the central log. To achieve an approximate load of the upper and lower saw drives, the machine is equipped with an electrical mechanism of lifting the feed-receive bench.


To eliminate the necessary often stoppages of the machine due to clogging of the sawdust extractor with wood shaves and pieces of bark, we installed in the bottom section of the machine a MINI-CHOPPER TM, which completely eliminates to need to stop the machine caused by stuffing and obstruction of the sawdust extracting channel. Thanks to the mini-chopper installed, the shaves and bark getting together with the sawdust into the extraction channel are immediately cut, and together with the sawdust dropped into the suction pipe of the sawdust extractor.

Main features of the TT-400

Minimised electrical power consumption 

Thanks to installing disc saws on the spindles put directly on the engine shafts, thus obtaining even load distribution of the engines by the means of the electrical mechanism of the bench lifting. 

Significant increase of efficiency 

Thanks to even load distribution of the engines 
(significant increase of the machine efficiency thanks to the above-mentioned solutions)

Quick change of the cut central log thickness 

On the machine body there have been installed two sliding engine plates; on each of them two engines, equipped with saw spindles, have been affixed. This enables a very fast and easy change of the thicknesses of the central log cutting without dismantling the cutting saws.
