3.1 General
For the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003 and the following
apply:
3.2 Definitions
3.2.1
surface planing and thicknessing machine
combined machine designed to plane a surface of a work-piece and to give it in a following operation a set
thickness by means of a horizontally rotating cutterblock, a cylindrical shaped complex tool equipped with
blades with horizontal straight cutting line that cuts while rotating (see for a description of the complex tool
also EN 847-1:2005)
NOTE The work-piece is fed into the machine against the direction of the cut.
When surfacing, the work-piece is passed over the cutterblock located between two tables which are used to position and
support the work-piece and the lower surface is planed. The infeed table of the surface planing unit is adjustable in height.
When thicknessing, both of the surfacing tables are raised. The work-piece rests on the thicknessing table the distance
between it and the cutting circle diameter is adjustable. The upper surface of the work-piece is planed
