Beams and planks from Oak, Siberian Ceder, Siberian Larch and Angara Pine do not undergo drying process, instead they are atmospherically dried to the natural level of humidity of 20-25%. As a result, after digital sorting of the beams on a special conveyor with cameras and sophisticated detection tools, the production process is rather straightforward:

1) Sawing
We saw the beams using multiblade saws for the purpose of getting uniformly correct width.

2) Preliminary trimming
Crosscut lathes eliminate the distortion and curvature of beams and reduce the allowance for further processing.
The machinery cuts the ends of blanks that have cracks after drying.

3) Defects examination
Examination of workpieces is performed using four-sided longitudinal milling machines.
These effectively determine surface imperfections and ready the workpieces for further processing.

4) Defects elimination
Elimination of defects/imperfections on workpieces. Obtaining defect-free workpieces for further
splicing along the length is done with the help of equipment for defect cutting and optimization processing.

5) Calibration
In essence it is longitudinal milling in order to obtain accurate geometric forms and
to obtain a high surface cleanliness to a level specified in technical parameters.

6) Trimming
Shaping of the finished timber to the given dimensions on the grinding machines.
