Cutter grinding machine - is so clamped in holder structures that it can move along all three space axes

Movement of the machine in the X- and y- axes is by means of a horizontally displaceable slide, and by a vertical variable in the z-axes. Horizontal and vertical variables constitute the unit in which the machine is clamped. Scaling on the movement ranges and corresp. stops contribute to high precision and cleanness of the cut and the grinding path. USE - To cut and grind solid workpieces.

Saw apparatus

A saw apparatus is described which consists of a saw unit with a saw housing and a motor-driven saw blade which is held on a longitudinal guide running parallel to the plane of the saw blade. The longitudinal guide is arranged in the edge area of a rotatable round table which in turn is let into a work rest which on one side of the round table, where the latter has a plunging slot continuous up to the periphery, has a recess, corresponding to the mitre-cut range, for the saw blade. The round table is provided with an extension arm which has a plunging slot in alignment with the plunging slot of the round table. This configuration results in the advantage that a smaller round table and thus also a smaller unit overall can be provided, although a large cutting range is to be covered.

Adjustable support for cutting apparatus

A cutting tool such as a tile saw is pivotally connected to a linear guide rod with a four-bar linkage. The linkage allows the cutting tool to be raised and lowered over a work table to facilitate plunge cutting. One link of the four-bar linkage is mounted over the linear guide rod in a fixed perpendicular relationship with the surface of the work table to ensure that the blade of the cutting tool is maintained in a similar perpendicular orientation throughout plunge cutting. This is achieved by adjusting the links of the four-bar linkage as a parallelogram linkage. A linear bearing is fitted between the fixed perpendicular link and the guide rod to allow the cutting tool and linkage to freely slide along an accurate linear cutting path.

Sawing device for panels made of wood, of plastic material, or similar

Die Sägeeinrichtung befindet sich in einer Anlage, in der aus einzelnen lamellenförmigen Hölzern (2) Platten hergestellt werden. Mit der Sägeeinrichtung werden die Platten in gewünschtem Maß gesägt. Die Sägeeinrichtung hat eine Sägeeinheit (15) die quer zur Platte verfahrbar ist, die auf einer Auflage liegt. Die Platten können einfach und kostengünstig gesägt werden, da die Auflage ein Transportband aufweist, auf dem in dessen Transportrichtung (18) verlaufende Längsprofile angeordnet sind. Sie liegen mit Abstand voneinander. Da sich die Längsprofile in Längsrichtung des Transportbandes erstrecken, ist ihre Lage für jede Länge der zu sägenden Platten ideal angeordnet. <IMAGE> The sawing device is located in a system in which boards are made from individual lamellar wood (2). The panels are sawn to the desired size using the sawing device. The sawing device has a saw unit (15) which can be moved transversely to the plate, which lies on a support. The panels can be sawn easily and inexpensively, since the support has a conveyor belt, on which longitudinal profiles running in its transport direction (18) are arranged. They are spaced apart. Since the longitudinal profiles extend in the longitudinal direction of the conveyor belt, their position is ideally arranged for any length of the panels to be sawn. <IMAGE>
