A machine featuring a treatment tool that grinds a surface to a desired profile, imparts a desired roughness to that surface, and removes contamination from the surface, the machine configured to control multiple independent input variables simultaneously, the controllable variables selected from the group consisting of (i) velocity, (ii) rotation, and (iii) dither of the treatment tool, and (iv) pressure of the treatment tool against the surface. The machine can move the treatment tool with six degrees of freedom.

Also disclosed is a laser system that can be installed on a machine for machining a workpiece and an operation method of a machine for machining a workpiece.

A wafer manufacturing apparatus includes an ingot grinding unit for grinding an upper surface of an ingot to planarize the upper surface of the ingot, a laser applying unit for forming peel-off layers in the ingot at a depth therein, which corresponds to the thickness of a wafer to be produced from the ingot, from the upper surface of the ingot, a wafer peeling unit for holding the upper surface of the ingot and peeling off a wafer from the ingot at the peel-off layers, a tray having an ingot support portion and a wafer support portion, and a belt conveyor unit for delivering the ingot supported on the tray between the ingot grinding unit, the laser applying unit, and the wafer peeling unit.

[Problem] To address the problem of conventional old wood texture or antique taste boards which lack natural looking worn effects and present an appearance of an artificial treatment applied thereto. [Solution] Unlike a conventional configuration in which the rotary shaft of a roll brush is simply and fixedly arranged parallel to the wood grains of a board to which surface treatment is applied or the painted surface where paint is applied to the wood grains, the rotary shaft may be obliquely set to any angle including a right angle, and may be rotationally driven at high speed at a given inclined angle relative to the horizontal surface of the board along a left to right direction of the roll brush. This makes different “contact strength” of a roll brush such as a metal brush obliquely applied to each right and left end of the board, thereby causing the inclined roll brush to peel off the wood grains or the painted surface where paint is applied to the wood grains with difference strengths for each end of the board. This makes it possible to implement “uzukuri” (brushing process) with different designs presented along a left to right direction of the board.

A machine (10) for grinding and/or polishing slabs of stone material, such as natural or agglomerated stone, ceramics or glass, comprises: a support bench (12) for the slabs to be machined. At least one working station (14) is provided above the support bench (12), said station comprising at least one pair of bridge support structures (16, 18) situated opposite each and arranged transversely on either side of the support bench (12). First means (19) are provided for performing a relative movement in the longitudinal direction of machining station (14) and slab on the support bench (12). The machine further comprises at least one beam (20, the two ends (22, 24) of which are supported by the support structures (16, 18), and at least one rotating spindle (26) with a sliding vertical axis mounted on the at least one beam (20). The beam (20) is movable transversely on the support structures (16, 18). The bottom end of the spindle (26) is provided with at least one tool-carrying support (28) rotating about the axis of rotation of the spindle (26). The machine is characterized in that it comprises second means (32) for performing a relative movement in the longitudinal direction of the at least one spindle (26) with respect to the support bench (12).
