Disclosed herein are components, systems, and methods of operating an abrasive fluid jet system that recycles and reuses abrasive particles. The systems and methods described enable accurate metering and consistent feeding of wet abrasive particles thereby reducing the time and cost of operations associated with drying the recycled abrasive particles prior to reuse. The system may adjust a ratio of wet abrasive to dry abrasive being provided to a cutting head to form an abrasive fluid jet. Components of the system may overcome challenges associated with clumping and other issues that result in difficulty metering wet abrasive.

A seal assembly includes a seal body and an energizer. The seal assembly is dimensioned to lessen the chance of certain failure modes, such as back jetting of pressurized fluid that gets behind the energizer during a pressurization operation. A ratio of a lateral distance of the seal body to an axial length of the energizer is between 0.400 and 1.7087. A ratio of the lateral distance to an inner radius of the seal body is between 0.10 and 0.401. A ratio of a web thickness of the seal body to the inner radius is between 0.068 and 0.0881. A ratio of the difference between a radial height of the energizer and a groove height of the seal body to the radial height is between 0.050 and 0.155. A ratio of the difference between the radial height and the groove height to the inner radius is between 0.015 and 0.3486.

Contour follower for a fluid jet cutting machine

Systems and related methods are provided for maintaining a spatial relationship between a tool of the multi-axis machine (e.g., fluid jet nozzle of a fluid jet cutting machine) and a workpiece to be processed by the tool. An example system includes a contour follower apparatus having a sensor and a gimbal assembly operable with the sensor to sense a deviation between a machine focal point and a gimbal assembly focal point defined by the gimbal assembly as the gimbal assembly rides upon the surface of the workpiece during operation. The system may further include a gimbal mount assembly configured to sense a collision event of the gimbal assembly with another object.
