Apparatus 10 and method for cleaning, rejuvenating or treating the internal surfaces of a timber barrel 28 with an abrasive, the apparatus 10 comprising a clamping arrangement that includes at least one clamp 21-24 for clamping the barrel 28. The clamp 21-24 being rotatable to rotate the barrel 28 about its axis and the clamping arrangement being operable to tilt the axis of the barrel 28 during rotation through at least about 20°, preferably 25-40%, to either side of horizontal.

An apparatus includes at least one memory configured to store at least one image of multiple pieces of deburring media used in a vibration deburring machine. The apparatus also includes at least one processor configured to analyze the at least one image to determine a condition of each of the multiple pieces of deburring media and determine an overall condition of the deburring media. The at least one processor is also configured to generate a graphical user interface containing a notification based on at least one of: the conditions of the multiple pieces of deburring media and the overall condition of the deburring media.

In one embodiment, a vibration barrel polishing method using a vibration barrel polishing system that includes a polishing tank having a bottom surface therein and a polishing jig capable of holding a workpiece and rotatable around a rotation axis is provided. This method includes a step of supporting the polishing jig in the polishing tank in a state in which a lowermost portion of the polishing jig is separated from the bottom surface, a clearance d between the lowermost portion of the polishing jig and the bottom surface being greater than or equal to a grain diameter of a polishing medium, a step of causing the polishing medium to flow in the polishing tank, and a step of rotating the polishing jig around the rotation axis in the state in which the lowermost portion of the polishing jig is separated from the bottom surface.

To detect whether barrel lids are fixed.

A centrifugal barrel polishing machine (A) includes: a plurality of rotary tanks (50) that rotate planetarily; barrel lids (26) that are attachable to and detachable from the rotary tanks (50); and a plurality of clamp shafts (32) that are provided individually in the plurality of rotary tanks (50) so as to be rotatable integrally with the rotary tanks (50). Each of the clamp shafts (32) is displaceable between in a fixing form for fixing the barrel lid (26) to the rotary tank (50) and in a releasing form for releasing the fixation of the barrel lid (26). It is detected by a first detection means (40) whether the rotary tank (50) is positioned in a detection area (D) on a revolution path of the rotary tank (50), and it is detected by a second detection means (43) whether the clamp shaft (32) of the rotary tank (50) positioned in the detection area (D) is displaced to the fixing form.

A barrel polishing apparatus has a barrel tank. The barrel tank includes a cylindrical fixed tank having a center axis and a rotary disk provided to cover a bottom portion of the fixed tank and rotatable about the center axis. The barrel polishing apparatus further includes a tilting mechanism. The tilting mechanism has a tilting shaft extending in a horizontal direction to tilt the barrel tank around the tilting shaft. The tilting shaft is disposed closer to the upper edge of the fixed tank than a centroidal line extending parallel to the tilting shaft and passing through the center of gravity of the barrel tank when viewed from a direction parallel to an extending direction of the tilting shaft.

A rock tumbler apparatus having a dual barrel assembly with energy-absorbing air gaps is provided. The air gaps may be evacuated or back-filled or filled with a sound absorbing gas or other material. The rock tumbler may be operably attached to a programming system, which may include a sound dampening cover. The rock tumbler may be programmed, for example, to tumble during certain times of day, continually, to pause at various time intervals, and to tumble in one direction or another.
