<p>The invention relates to a machine for manufacturing correction wooden plugs meant to replace black falling knots from the timber with a view to improving the aesthetic quality thereof. According to the invention, the machine has a system for milling the correction plug and a circular saw for cutting the finished plug from a cylindrical wooden blank (1), where, for a perfect vertical axial alignment of the cylindrical wooden blank (1) with the symmetry and rotation axis of a milling cutter (22), as well as for providing an advanced parallelism between the bottom face of the blank (1) and the plane face of a metal table (9), there is employed a three-point clamping system achieved with two pistons (7 and 8) of two pneumatic cylinders (5 and 6) and an internal wall of a cylindrical guiding and clamping bushing (2), the axes of the three clamping points of the cylindrical wooden blank (1) forming an angle of 120° with each other.</p> |
