Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The invention is explained in more detail in the following text on the basis of at least one exemplary embodiment with reference to the drawings, in which:

[0020] FIG. 1 shows a schematic illustration of a first exemplary embodiment according to the invention of a machining device, and

[0021] FIG. 2 shows a schematic illustration of a first exemplary embodiment according to the invention of a machining device.

PREFERRED EMBODIMENT OF THE INVENTION

[0022] FIG. 1 shows a machining device 1, in particular for machining workpieces made of wood, wood materials, plastics material or the like. The machining device 1 has a workpiece holder 2 by means of which workpieces 3 can be held for machining.

[0023] The machining device also has a guide means 4 for displaceably guiding a tool slide 5, in order to hold and move a first tool 6 and a second tool 7.

[0024] In this case, the workpiece holder 2 and/or the guide means 4 are configured to De displaceable by means of displacement means 8, 9, in order to produce a relative movement in a machining direction 10 between the workpiece 3 and the first and the second tool 6, 7 in order to machine the workpiece in the machining direction.

[0025] FIG. 1 shows that the tool slide 5 is arranged on one side 12 of the guide means 4 so as to be displaceable, for instance shiftable in the direction 11. According to the invention, the tool slide 5 bears two tools 6, 7 alongside one another on one side 12 of the guide means 4 and in the machining direction 10 of the workpiece.

[0026] This means that the spacing of the tools can be kept small, for example can be kept in the region of about 40 cm. In this case, the spacing is the axial spacing 13 of the tools 6, 7.

[0027] As a result of being arranged on the tool slide, the two tools 6, 7 are arranged so as to be movable jointly in a first direction 11 perpendicular to the machining direction 10 by means of the tool slide 5. In this case, the first direction is typically the y direction while the machining direction is the x direction.

[0028] Provided on the tool slide are secondary slides 14, 15. In this case, at least one of the tools 6, 7 is, or both of the tools 6, 7 are each arranged on a secondary slide 14, 15, wherein the secondary slide(s) 14, 15 is or are arranged on the tool slide 5 such that the tool 6, 7 is movable in a second direction perpendicular to the first direction 11 and perpendicular to the machining direction 10. In this case, the second direction 22 is, the z direction, which is perpendicular to the plane defined by the first direction 11 and the machining direction 10.

[0029] FIG. 2 shows a further exemplary embodiment in which two tools 6, 7 are likewise arranged on the tool slide 5, said tools 6, 7 each being arranged in a displaceable manner on secondary slides 20, 21. In this case, at least one of the tools is, or both of the tools are each arranged on a secondary slide 20, 21, wherein at least one of the secondary slides, or the secondary slides is or are arranged on the tool slide 5 such that the tool 6, 7 is also movable in the first direction. Thus, in the exemplary embodiment in FIG. 2, the secondary slide 20 is embodied such that a movement in. the first direction 11 is also possible. In this case, the secondary slides are also configured such that the tools are also displaceable in the second direction. As a result of the adjustment of the tool 6 in the first direction 11 with at least a small travel, the penetration depth of the tool 6 into the workpiece can be controlled individually. In this case, the penetration depth of the other tool 7 can be effected by the position of the tool slide 5.

[0030] In both exemplary embodiments, it is advantageous for a respective drive arrangement having a tool receptacle to be arranged on the tool slide 5 or on the secondary slide(s) 14, 15, 20, 21, in order to receive and drive a respective tool 6, 7 for machining the workpiece 3. In this case, the drive arrangement is in the form of a simple drive spindle or of a spindle unit, such as in particular a 4-axis or 5-axis spindle unit.

[0031] According to the invention, the respective tool 6, 7 is a cutting tool, such as in particular a milling tool, a drilling tool or a sawing tool. Edge machining devices for applying edge material or for finishing applied edge material are not explicitly intended to be considered tools, rather only tools which machine the workpiece itself by cutting.

[0032] Depending on the configuration of the machining device 1, the guide means 4 can be is the form of a stationary gantry or of a stationary extension arm. In this case, it is advantageous for the workpiece holder 2 to be configured so as to be displaceable by means of displacement means 8, such as a drive and guide means, and as a result displaceably guide and displace the workpiece 3.

[0033] Alternatively, the guide means 4 can be in the form of a displaceable gantry or of a displaceable extension arm which is displaceable with the displacement means 9, wherein it would be advantageous for the workpiece holder 2 to be in the form for example of a stationary workpiece table.

[0034] As a result, it is in each case possible for the workpiece 3 to be able to be guided easily and efficiently past the two tools 6, 7 in the machining direction 10, in order to machine the workpiece.
