Surface processing machine for hard-fired ceramic tiles

Abstract

The facing machine for hard-fired ceramic tiles (1) comprises: a structure (23, 15) for supporting, and setting (17) the cutting depth of, at least one pair of rotary rollers at a grooving station (16), the axis of said rollers lying transverse to the infeed path (A) of said tiles as carried on a belt transport (24); said rollers comprising a plurality of disks (3) formed with diamond-tipped cutting teeth (4) and a facing station (25) comprising a plurality of vertical-axis grinding wheels with abrasive diamond-tipped tooling; said rollers (2, 7) are carried on a common supporting structure (12), being adjustable (17) in height to set the tool cutting depth in the tile; said structure (12) being pivotable about a parallel shaft (13) to the work surface in a transverse direction to the feed direction (A) of the surface, and being associated with a device (14) for adjusting and inhibiting the pivotal movement of the structure in order to accommodate varying cutting diameters of the rollers at said station.

Description

technical field [0001] The present invention relates to a surface finishing machine for processing high-temperature fired tiles, and more particularly, to an improved surface processing machine capable of surface processing such tiles with simpler operations. Background technique [0002] The prior art provides a variety of machines for surface finishing stone. Such machines traditionally use diamond grinding rolls in which the abrasive material extends in a helical path around the cylindrical surface of the roll in order to cut the entire surface of the stone to be machined. Although the generatrix of the tool envelope contacts the workpiece surface with only a portion of its helix at any time during machining, the cutting action still affects the distance spanned by said generatrix because the point of contact always moves continuously along the helix as the roller rotates. entire workpiece area. The end result is that the entire surface spanned by the bus bar is machine...

Problems solved by technology

[0004] However, the performance of this alignment machine does not justify much improvement over the helical grinding roll alignment machine, mainly because the large number of discs placed side by side on the grooved roll makes it difficult to manufacture a sufficient number of narrow grooves. Slots and bumps for adjustment

The plate surface can be machined more precisely by reducing the number of discs, but the ridges formed on the plate surface will become wider, thereby significantly reducing the working rate of the diamond grinding ring plate

[0005] In addition, the prior art described above, when applied to the face side of the high-temperature fired tile rather than the back side of the granite slab, requires frequent tool adjustments and prevents modern vertical The production potential of the shaft-rotating heads is completely exhausted because of the difference in depth that affects the throughput and the movement effectiveness of the latest rotating grinding tools for these heads
