WEBER PT K

Deburring machine for flame-cut and plasma-cut parts

``````````

The PT K model range is the compact version of the PT series. Deburring, rounding and descaling of of thick and considerably warped plates and sheet metal parts is no problem for the PT K. Deburring is performed by the WEBER STC bolt grinding beam. Should the parts require edge rounding after deburring, additional stations, such as the WEBER DR planetary head or the WEBER MRB multi-rotation brush, can also be integrated.

		WEBER GD Grinding roller
		For surface finishing, WEBER uses its GD grinding roller: A perfect surface finish and ideal deburring are achieved in a single operating sequence. The grinding pressure is generated by positioning the roller downwards below the zero level. When the roller approaches the workpieces, the rubber coating of the roller is pushed inwards. The restoring force of the roller is thus the grinding force. Grinding rollers are available with different diameters and rubber hardness and can be adapted to all parts to be ground.

		WEBER DR Planetary head
		WEBER uses its planetary head technology for all-round edge machining with cup brushes. In this process, several rotating brushes arranged in groups are given an additional turning motion. This means that the brushes work at the ideal angle on the workpiece. In the patented WEBER solution, the tools of adjacent heads overlap in a way that ensures that there are no gaps during machining. As an alternative, we at WEBER also construct a two-row arrangement in which each tool carrier is equipped with six brushes.

		WEBER STC Bolt grinding beam
		With this grinding beam system, WEBER has taken machining of thick and uneven plates to a new level: A constant grinding quality, a high material throughput and low operating costs due to a high grinding belt operating life are characteristic for this technology. This function is simple, but well conceived. The grinding belt is pre-tensioned downward by a few millimetres and held in a flat position. Due to the long contact surfaces with the workpieces, it makes a stronger impact on all edges without creating secondary burrs. The pre-tension compensates for existing thickness differences between one part and another by itself and therefore makes economic multiple feeding possible – an enormous advantage, especially for small parts.

		WEBER BS Brush rollers
		The BS brush rollers are used for removing secondary burrs after grinding or milling. They machine the surface and to some extent the edges. For system-related reasons, the rounding action is much more effective on the transverse edges than on the longitudinal edges that are barely rounded. The BS brush rollers improve the surface quality, change the surface roughness or surface structure. They also make it possible to remove material residue after grinding or milling without damaging the surface.

		WEBER MRB Brush system
		When round brushes are used, several rotating heads are also arranged next to each other. The meshing of the brushes during the combing procedure and two brushes per head create even machining results along the entire operating width. The modular design of the brush heads allows for problem-free machining of each part with the procedure it requires. This arrangement works perfectly for any material thickness starting from one millimetre.

		CBF Grinding beams
		The patented WEBER CBF system presses the grinding belt against the workpiece via a segmented grinding beam. In this way, diverse grinding patterns are possible with an easily adjustable line length. Even machining thicker metal sheets is no problem for this system – and it is all accomplished with a longer grinding belt service life and lower material heating.

WEBER K Combination unit

Plates of different thickness are cut by means of different procedures and with different cutting parameters. Furthermore, plates of different thickness have different characteristics, which influence burr formation. The thicker a plate, the greater the thickness differences after cutting, due to warping and burr formation.

WEBER has been offering a solution to this problem for several years. The advantages offered by a flexible grinding beam and the performance of a grinding roller - optimised and combined in one grinding station – yield perfect results.
