A waterjet system in accordance with at least some embodiments includes a carriage, a motion assembly configured to move the carriage horizontally relative to a workpiece, and a cutting head carried by the carriage. The waterjet system can also include a kinematic chain through which the cutting head is operably connected to the carriage. The kinematic chain can include first, second, and third joints rotatably adjustable about different first, second, and third axes, respectively. The carriage and the first and second joints can be configured to move the cutting head along a path relative to the workpiece while the cutting head directs a jet toward the workpiece to form a product. The third joint can be configured to shift a kinematic singularity away from the path to reduce or eliminate delay and corresponding reduced cutting accuracy associated with approaching the kinematic singularity.

The present disclosure provides an adjustable device for removing burrs of a back cavity of a wheel. The adjustable device for removing the burrs of the back cavity of the wheel includes a frame provided with a rotary table inside, a support frame is fixedly connected to the rotary table, and a left rotary table and a right rotary table are arranged on the support frame. The device is ingenious in design, novel in conception, high in universality, short in cycle time and high in efficiency, and is suitable for removing burrs of wheels in different specifications.

In an automatic polishing system configured such that under control of a polishing robot and/or a polishing tool by a polishing controller, the polishing tool provides a polishing action on a polishing subject face, a color intensity measurement instrument is provided for measuring an intensity of a specified color in the polishing subject face. Based on the intensity of the specified color measured by this color intensity measurement instrument, the polishing controller controls the polishing robot and/or the polishing tool, so that an amount of polishing work by the polishing tool onto the polishing subject face is adjusted according to the intensity of the specified color.

A walk-behind, wet/dry grinder/polisher adapted for concrete floors does not use of pulleys, belts or chains. Maintenance is significantly enhanced, as such components are typically the first to wear out and cause replacement issues. A frame with forward and rear portions pivots about a single set of right and left wheels. A planetary grinding head, powered by a propane engine, is coupled to the forward portion of the frame. In contrast to all known designs, the engine is directly, mechanically coupled to the grinding head without the use of pulleys, belts or chains. The direct, mechanical coupling to the grinding head preferably uses a centrifugal clutch. A water tank and water feed line from the water tank to the grinding head facilitate wet floor grinding and polishing. The grinding head is also encased in a shroud coupled to a tube for dust collection associated with dry floor grinding and polishing.

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.

A pipe coating removal apparatus (1) for removing all or some of the coating on a pipe, the pipe coating removal apparatus (1) having a pipe support means (2) for supporting a length of pipe. and further having a tool carriage (3). The tool carriage (3) being capable of supporting two or more different types of pipe coating removal tools (4), (5), (6), (7), (8), (80), (81), (82) and/or (70). The pipe coating removal apparatus (1) being capable of causing relative movement between the tool carriage (3) and the pipe support means (2) to remove all or some of the coating on the pipe that is supportable by the pipe support means (2).

A grinding or polishing device and a method for treating a workpiece are provided. The grinding or polishing device includes a tool holder for holding a grinding or polishing tool and a mounting head for mounting the tool holder to a multi-axis manipulator. The tool holder is rotatable with respect to the mounting head about a pivot axis. The grinding or polishing device further includes a sensor for converting at least one parameter indicative of an angular position of the tool holder about the pivot axis into an output signal that can be used for determining a control signal for controlling the multi-axis manipulator.

A method for cylindrical grinding of cylindrical workpieces on a grinding machine, in which an axes of rotation of a grinding disc and of the workpiece are aligned in parallel to one another and the grinding disc is moved relative to the workpiece in a longitudinal-axial direction of the workpiece during the grinding process. A first grinding disc is followed by a second grinding disc at a continuously constant distance. The distance is determined by the width of the first grinding disc and the remaining grinding parameters, such as the rotational speeds of the first grinding disc and of the workpiece and the feed rate in the longitudinal-axial direction, such that the second grinding disc grinds the helical error lines generated by the first grinding disc during the grind process. A control device adjusts the distance between the first and second grinding discs.

A system and a method for processing of optical lenses in which the processing takes place by different processing apparatus between which there is a respective transfer apparatus. The transfer apparatus are used both for longitudinal and also cross conveyance. Each processing apparatus has its own conveyor apparatus which is controlled by the processing apparatus itself. The transfer apparatus are controlled by a central transfer control.
