Abstract: A method and a plant are provided for calibrating surfaces of stone materials, suitable for working at least one slab (1) composed of an entry side and an exit side and of two parallel side edges; the slab (1) is pushed along the side edges through a conveyor belt and is subjected to the cutting action imparted by multiple tools equipped with a peripheral speed compatible with optimum cutting parameters for the stone material; the tools move along a predefined path along the surface of the slab (1), and the motion imparted by the conveyor belt and the predefined tool path is combined in order to completely cover the surface of the slab (1); the contact between the slab (1) and the tools is ensured simultaneously at least in one point on each of the two side edges of the slab (1).

Abstract: A device for processing a slab of stone or stone-like material, includes a support table, adapted for receiving the slab, and a fixed guide rail running in a first direction along a side of the support table. The device further includes an arm, extending in a cantilevered manner, in a second direction from the guide rail and across at least a portion of the support table. The arm is displaceable relative the guide rail in a third direction. A method for processing a slab of stone or stone-like material is also disclosed.

Abstract: A device (1) for processing a slab of stone or stone-like material, comprises a support table (2), adapted for receiving slab, and a fixed guide rail (3) running in a first direction (X) along a side of the support table. The device further comprises an arm (4), extending in a cantilevered manner, in a second direction (Y) from the guide rail and across at least a portion of the support table. The arm is displaceable relative the guide rail in a third direction (Z). A method for processing a slab of stone or stone-like material is also disclosed.

Abstract: A method to create blocks having a weathered and aged look by modifying the blocks before they are cured. Green blocks exiting a block forming machine are conveyed along a path past brush elements which scrub block mix from the upper longitudinal corners of the formed, uncured blocks. The blocks are also passed longitudinally over tooth elements which irregularly remove block mix from the lower longitudinal corners of the green blocks. The modified green blocks are moved to a kiln for curing.

Abstract: A method and apparatus for polishing and planarizing workpieces such as semiconductor wafers is presented. Conditioning rings, which are used to condition polishing pads used in the planarization or polishing of semiconductor wafers, are shown which utilize brazed diamond technology in association with a coating of a titanium nitride containing composition or a thin film diamond deposition in order to reduce the fracturing and loss of cutting elements bonded to the conditioning ring.

Abstract: A cutting machine including a base connected to an end of an arm of a construction machine with a pin. A cutter mounting assembly is rotatable relative to the base, and a rotary cutter is mounted on the cutter mounting assembly. The cutter mounting assembly has a fixed portion and a movable portion, a drive device that extends and retracts linearly disposed on the fixed portion, a rotary cutter disposed on the movable portion, the rotary cutter mounting assembly being rotatable relative to the base.

Abstract: A radius dresser is provided including a base removably secured to a recipient surface. Also included is a cutting tip holder rotatable and radially slidable with respect to the base. The holder is selectively fixed with respect to the base. The holder has a cutting tip situated along a radius which remains along a direction in which the cutting tip holder is slidable.

Abstract: A conditioning ring having cutting elements brazed-bonded to the bottom surface of the ring and suitably adopted for conditioning a workpiece polishing pad by contact with the pad. The conditioning ring further includes a flange extending about the bottom periphery of the ring with the cutting elements being attached to the bottom surface of the flange. The flange includes cutout portions for permitting material to escape from the interior of the ring. The cutting elements are distributed substantially uniformly across the bottom surface of the flange and the elements are brazed-bonded to the flange with a braised metal alloy, creating an extremely strong bond between the cutting elements and the flange surface.

Abstract: A clamping apparatus for mounting and positioning a diamond type dressing stone in proximity to a grinding wheel is provided to permit adjustable orientation of the dressing stone relative to the grinding wheel. The apparatus includes a support block adjustably mounted to an upper positioning block through a parallel link structure utilizing clamping rods directed orthogonally adjacent post terminal ends of clamping links to secure the upper block in a relative position relative to the support block.

Abstract: Apparatus is provided for supporting and guiding a router for the purpose of routing an ornamental design in panels such as cabinet doors and drawer fronts. The router is attached to the end of a bar extending over the workpiece, the bar being slidable longitudinally in a carriage which in turn is movable on a rail extending at right angles to the bar. Adjustable stops are provided to limit movement of the bar and carriage so that the router may be guided in a rectangular path of movement of predetermined dimensions. Selectively usable templets are provided for changing the path of movement of the router, particularly at the corners of the predetermined rectangular path to vary the design being routed.
