摘要： 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.

摘要： A wet abrasive blasting system includes a vessel having multiple outlets for dispensing slurry. A first sprayer of the system is operatively associated with a first blast control switch, and a second sprayer is operatively associated with an n-th blast control switch. A first blast line fluidly connecting the first sprayer to the first outlet includes a first pinch valve, and an n-th blast line fluidly connecting the n-th sprayer to the n-th outlet includes an n-th pinch valve. A time delay module of the system transmits signals to close all system pinch valves upon receipt of signals indicative of an actuated state of more than one blast control switch and, after a predetermined time delay, transmits signals to open all system pinch valves associated with their respective actuated blast control switches.

摘要： An independent safety warning and notification system for sandblasting operations that require an operator of a blasting hose to be remotely positioned to the blasting pot operator. A dedicated activation switch assembly is secured to an existing sandblast hose with a separate dead man switch or alternately with an integrated dead man switch allowing the blast nozzle operator to communicate critical information to the pot operator. A warning notification light display and audible alarm assembly with a remotely positional warning light alarm is selectively secured near the pot operator for notification that a prescribed predetermined action has been requested by the blast nozzle operator or an emergency situation by activation of the switch assembly.

摘要： A sand source selecting structure for a sandblasting gun has a main body; a channel provided in the main body, for passing a high pressure gas; at least two sub-channels provided in the main body respectively connected to the channel; a sandbox mounted on the main body connected to the channel through each of the sub-channels; at least one supply tube; a first control valve installed in the main body, for connecting the sandbox and at least one of the sub-channels of the channel; and a second control valve installed in the main body, for connecting the channel and another sub-channel of the supply tube. Therefore, the combination of the first control valve and the second valve provides a selecting structure, which can offer different sand supply sources.

摘要： A waterjet system in accordance with at least some embodiments of the present technology includes a tube configured to carry ultrahigh pressure liquid, and a fitting connected to an end portion of the tube. The fitting includes a body and a clamping block that secures the tube to the body. The body includes a recess, a passage extending inwardly from the recess, a sealing surface extending around the passage, and a sidewall extending around the sealing surface. The sealing surface meets the sidewall at an annular corner within the recess. The clamping block includes first, second, and third through holes spaced apart from one another. The tube extends through the first through hole and is secured to the clamping block via a threaded connection. First and second clamping bolts extend through the first and second through holes, respectively, and into respective threaded openings in the body.

摘要： A water jets cutting machine includes a first rotating seat driven by a first motor to rotate about a first rotation axis, a second rotating seat driven by a second motor to rotate about a second axis, a water jets cutting head, an inertial measurement unit (IMU) for detecting an inclination angle of the water jets cutting head, and a controller connecting the first and second motors and the IMU. The controller is able to control the first and second motors to instantaneously conduct compensation for angular deviation of the water jets cutting head according to attitude and position signals which are fed back to the controller by the IMU.

摘要： The invention relates to a method for producing a screen netting (1), whereby openings (2) are made in a blank by means of water jet cutting, whereby the water jet cutting is carried out in several steps, whereby in a first step, a pre-cutting of the openings (2) of the screen netting (1) is carried out, and in at least one second step, a finish-cutting of the openings (2) of the screen netting (1) is carried out. The invention also relates to a screen netting (1) that is produced in such a way.
