Definitions

  • the invention relates to a method for low-tear end profiling of frame timbers according to the preamble of claim 1.
  • the counter timbers can be used in association with the respective end profiles. If the milling tools are arranged one above the other in a support that can be raised and lowered, a row that can be controlled when the workpiece ends are traversed and with counter areas arranged one above the other is usually mounted on this same support.
  • This arrangement has the disadvantage that only the same profile workpiece contact sides can be effectively countered for each end profile.
  • DE 36 29 075 A1 discloses a method for the continuous longitudinal gluing of finger-jointed woods and a device for carrying out this method with a finger jointing system.
  • This finger jointing line has a vertically movable milling slide on which a main milling spindle with two assigned scoring spindles is mounted.
  • the scoring spindles can be swiveled around the main milling spindle.
  • one scoring spindle is brought into the working position in order to pre-mill the tool. With this pre-milling, wood is removed from the workpiece at the point at which the main milling spindle leaves the workpiece during milling, so that this wood cannot be torn out.
  • This long-known method for the continuous longitudinal gluing of finger-jointed woods is not applicable to the low-tear end profiling of frame timber.
  • the depth of the end profile can be greater than the width of the workpiece when machining frame timber.
  • the scoring cutter would emerge on the opposite side of the workpiece and produce tears here. This is due to the fact that the deeper the end profile of the workpiece is, the deeper the peripheral cutter for the preliminary milling must be run in on the side of the workpiece which is at risk of being torn out. If the workpiece also only has a small workpiece width, the revolving milling cutter emerges on the opposite side of the workpiece before the entire width for pre-milling is reached.
  • a contour can be cut in on the workpiece side which is at risk of being torn out, without this cutting tool emerging on the opposite side of the workpiece. This basically avoids tearing out on this opposite workpiece side.
  • the cutting edges of the tool which cuts even in the case of very narrow workpieces, do not emerge at any point on the workpiece side opposite the workpiece side which is at risk of being torn out.
  • Figure 1 shows a workpiece 12 as a frame wood for windows with a workpiece end 1, which is to be machined with a profile milling tool 2 for final profiling.
  • the contours for the final profiling are drawn in as dash-dotted lines 3 in FIG. 1.
  • the workpiece fibers run approximately in the direction of the double arrow 4. Since the profile milling tool 2 rotates in the direction of the arrow 5 shown and the workpiece is to be shifted in a straight line in the direction of arrow 6 along the broken line 6.1, the workpiece side 7 is with the surfaces 7.1 and 7.2 risk of tearing. There is a particular risk of tearing out at the contours 3.1, 3.2 and 3.3.
  • incisions 9.1, 9.2 and 9.3 are made at a depth which, given the wood properties in conjunction with the notch effect at the bottom of the incisions Migration of the splits and cracks that occur during the end profile milling due to the cutting pressure into the workpiece areas not intended for machining is prevented.
  • the milling cutter 8 only processes the workpiece side 7 which is at risk of being torn off, and does not emerge from the opposite side 14 of the side 7 of the workpiece which is at risk of being torn off, even with a very small width 13 of the workpiece 12.
  • the depth of the incisions 9.1, 9.2 and 9.3 through the milling cutter 8 is consequently worked out both as a function of the given wood properties and as a function of the width 13 of the workpiece 12.
  • the milling cutter 8 is movable in the directions indicated by double arrows 10. It can therefore be rotated and moved in the coordinate directions X, Y and Z.
  • the workpiece end 1 is provided with cuts 15.1, 15.2 and 15.3 according to FIG. 2 by a milling cutter 8.
  • the workpiece end 1 was cut at the contours 3.1, 3.2 and 3.3 at risk of tearing by means of plunge cutters 11.1, 11.2 and 11.3, which has the further advantage over the design of the cuts according to FIG. 1 that the contours are cut into the corners with sharp edges can be.
  • the arrows 15 in FIG. 3 indicate the direction of movement of the piercing knives 11.1, 11.2 and 11.3.
