Definitions

  • the invention is usefully applicable in edging pieces of tiles or slabs, previously cut from ceramic tiles or slabs destined, for example, to be used as skirting board.
  • the edging is usually a rounded bevelling.
  • the main aim of the present invention is to obviate the limitations and drawbacks in the prior art by making available, directly in the work-site or the laying site, a machine for shaping edges of tiles or slabs and/or special elements made from the former.
  • 1 denotes in its entirety a frame having legs 10 for resting on the ground.
  • a work plane 2 is supported on the frame 1, which work plane 2 is inclined with respect to the vertical, along which a workpiece slide 3 moves; the workpiece slide 3 feeds the workpiece to the machine.
  • the frame 1 and the legs 10 are predisposed so that when the legs 10 rest on a horizontal surface, the angle of inclination P of the work plane 2 with respect to the vertical is of about 60° and the direction of motion of the workpiece slide 3 is horizontal.
  • the workpiece slide 3 is provided with a handle 13 for translating in a horizontal direction and is provided with a blocking organ i.e. a lever 23 which blocks the workpiece 11 to the slide or the table; in the embodiment the workpiece 11 is a special element, previously cut away from a tile or slab.
  • a blocking organ i.e. a lever 23 which blocks the workpiece 11 to the slide or the table; in the embodiment the workpiece 11 is a special element, previously cut away from a tile or slab.
  • a motor head 4 is constrained on a portion of the frame 1 arranged at 90° to the work plane 2.
  • the motor head 4 bears a tool-bearing chuck as well as the motor itself, and the transmission for the motor.
  • the motor head 4 is supported on a motor slide 5, to which it is hinged by a pivot 6 having an axis which is perpendicular to the work plane 2.
  • the motor slide 5 is coupled to the frame 1 and can be translated and adjusted regarding its position with the frame 1 in a perpendicular direction to the work plane 2.
  • the adjustment of the position of the motor slide 5 is made possible by the predisposing of a screw device 12 of known type, which is easily manoeuvrable from outside and enables achievement of a precise positioning along the direction of the tool-bearing chuck on the motor head 4, and therefore a precise positioning also of the tool in the chuck.
  • the tool-bearing chuck is made to bear a cutting tool which in the preferred embodiment is a grinder 9.
  • the whole motor head 4 is mobile in rotation about the pivot 6, so that an angular position thereof can be adjusted.
  • the position is determined by a screw 7, operating between the frame 1 and the motor head 4, which screw 7 acts against elastic means 8, also operating between the frame 1 and the motor head 4.
  • the screw 7 is used to adjust the position of the grinder 9 in a perpendicular direction to the workpiece slide 3 motion direction, and a parallel direction to the work plane 2. Adjustment of the position of the grinder 9 in a parallel direction to the rotation axis of the grinder 9 and perpendicular to the workpiece slide 3 and the work plane 2 is done by adjusting the motor slide 5.
  • the grinder 9 is powered in the cutting direction, while the in-feeding of the workpiece 11 is done manually using the handle 13, with the workpiece 11 blocked on the workpiece slide 3.
  • the inclination to the vertical of the work plane 2 means that the work can be done very simply, as the force of gravity is used to achieve a correct reference orientation of the workpiece 11 with respect to the grinder 9.
  • the inclination further enables the cutting liquid (water) to be easily collected, as it falls by gravity into the underlying tray 14 fixed to the frame 1.
