2 PORTAL-ZWEIBAND-SCHLEIFMASCHINE TYPE PZM PORTAL TWIN-BELT GRINDING MACHINE TYPE PZM Die Maschine wurde für das Bearbeiten großvolumiger Bauteile wie Maschinenständer, Schaltschränke, Gestelle, Säulen usw. konzipiert. Mit den beiden hintereinander angeordneten Schleifbändern, die ohne Kraftaufwand verformt und gekippt werden können, lassen sich Schweißnähte sauber verrunden und Radien übergangslos an die angrenzenden Flächen anpassen. The heavy duty range of PZM machines are designed for processing of bulky components such as machine stands, enclosures, frames or heavy box / round sections. Equipped with two grinding belts running in parallel - which can be power swivelled - weld seams can be rounded off to give an even radius and surfaces blended into the surrounding areas. A scissor lift table, on a rail mounted carriage, is fitted with Ein auf einem Fahrwagen angeordneter Scherenhubtisch precision bars which support easily moved and interchangeist seitlich mit Rundführungen für den Maschinentisch able work tables, standard universal fixturing or bespoke oder für eine Handlingvorrichtung ausgerüstet. clamping arrangements. Die Bänder werden über eine, zwischen Antriebsund Spannstation angeordnete, hochgezogene Umlenkeinrichtung geführt. Dadurch ergibt sich ein freier Arbeitsbereich, in dem der Bediener gefahrlos arbeiten und sein Schleifergebnis beobachten kann. Abrasive or Nylon web belts are guided around a three pulley system resulting in a triangular design, giving the operator an open and safe working area which allows for a continuous inspection of the grinding result. 1

Die Steuerung von Wegen, Drücken und Geschwindigkeiten erfolgt mit einer SPS SIMATIC S7. To process even larger surfaces the Portal Twin-Belt Grinding Machine can be equipped with automatic tools and a drive for the scissor lift table. For all automatic processes, a PLC SIMATIC S7 is used to control the guide ways, working pressures, and feed speeds. Der Maschinentisch kann gegen eine WerkstückHandling-Einrichtung ausgetauscht werden. Mit Saugspannern befestigte Gehäuse, Hauben und Gestelle sind in alle Richtungen zu bewegen. Maschinentisch und Handling-Einrichtung können in einem hinter der Maschine angeordneten Ständer geparkt werden. The machine table can be exchanged easily for a Handling Device; clamped by vacuum, it is possible to tilt, rotate and move Enclosures, boxes, hoods and stands in any direction. The machine table and Handling Device can be stored in a racking system out of the way behind the machine. 2

4 An den Fahrwagen des Hubtisches lassen sich Gabelzinken anordnen, auf die bis zu 2 m hohe Bauteile gestellt werden können. Der Bediener steht auf der Plattform des Hubtisches. Für die Vorschubbewegung wird die Schleifeinheit mit einer Horizontalverstellung ausgerüstet. Loading forks, to take up to 2000 mm high components, can be positioned on the table carrier; the operator using the lift table as a working platform. For ease of use and access, the grinding unit can be equipped with fore and aft horizontal adjustment. Maschinenständer, Gestelle und Gehäuse, die an mehreren Seiten geschweißt sind, lassen sich rationell bearbeiten, wenn sie mit einem Drehtisch schnell bewegt werden können. Machine stands, racks, enclosures welded on multiple sides can be easily and economically processed if a turn ring is used for the movements. Für das Bewegen von schweren und großvolumigen Werkstücken werden verschiedenartige elektrisch angetriebene MANIPULATOREN angeboten. Die Befestigung der Teile an dem Schwenkkopf erfolgt mit Permanentmagneten, Vakuumsaugern oder pneumatischen Spannzylindern. For the movement of even heavier and bulky workpieces motor driven manipulators can be offered. The clamping of the parts on the swivel head can be by magnets, vacuum or pneumatic cylinders. 3

5 In vielen Industriebetrieben werden Maschinen und Anlagen komplett aus Edelstahl hergestellt. Neben der chemischen Beständigkeit des Materials ist die Oberflächenqualität im Hinblick auf Optik und Hygiene von ausschlaggebender Bedeutung. Nur durch das Schleifen der meistens gekanteten und geschweißten Bauteile lässt sich die Anforderung erfüllen. Die PORTAL-ZWEIBAND-SCHLEIFMASCHINE TYPE PZM wurde für die Bearbeitung von großen Tanks und Gehäusen konzipiert. Aber auch lange Säulen, Fassadenbauteile und Großkücheneinrichtungen lassen sich problemlos schleifen. Wenn die Maschine zusätzlich mit einer Handling-Einrichtung ausgerüstet wird, lassen sich geschweißte Kleinteile rationell bearbeiten. Beispiel: Hubgerät Example: Lifter Beispiel: Pflanzenbehälter Example: Plant container Beispiel: Fleischereimaschine Example: Food processing machine In many industrial companies, machinery and other products are made from high-grade steel. Apart from the chemical stability of the material surface finish is important for visual and hygiene reasons. The desired surface quality of formed, fabricated and welded components can only be attained by grinding. The PORTAL TWIN-BELT GRINDING MACHINE; TYPE PZM is designed for the process of bulky machine stands, tanks and covers. Long, heavy, large section round and rectangular tube, open framed constructions, housing components and industrial kitchen elements, are easy to grind. If the Handling Device is specified it is possible to efficiently process welded small parts in addition.
