A treatment machine for adjusting a K factor of a cutting edge of a worktool is described. In an embodiment the treatment machine comprises: a blast gun for directing a pressurised blast stream of abrasive particles in a blast direction; mounting means for securing the worktool such that a rotational axis of the worktool is radially offset from the blast direction by an offset distance, and wherein control of the offset distance between the blast direction and the rotational axis adjusts the K factor of the cutting edge.

The invention features methods and apparatuses for altering a cutting operation during operation of the pressurized liquid jet cutting system. A pressurized liquid jet cutting system includes a pressurized fluid jet cutting head having a plurality of components. The cutting head further includes a sensor configured to sense an operating condition. The sensor transmits a value of the operating condition to a computing device, which alters a subsequent cutting operation. Further, the fluid jet cutting head is configured to work with a data storage mechanism and a reader, such that the data storage mechanism in contact with a body of the fluid jet cutting head is configured to communicate information to a reader of the pressurized liquid jet cutting system. The information is usable to determine a condition of replacement (e.g., a remaining usable life) of the replaceable component, change an operating pressure, change a cutting speed, or alter another operating parameter of the pressurized liquid jet cutting system.

A shutdown system for a media blast system includes a normally closed diverter path which remains closed to air flow during operation of the blast system. During shutdown, the air flow to the metering valve is shut off, shutting off the system. At the same time, the diverter path is opened, relieving pressure in the supply line by permitting pressurized air and abrasive in the supply line to back flow through the diverter from which it is exhausted, almost instantaneously shutting off flow through the nozzle. A diffuser system is included for receiving and exhausting residual abrasive media and for reducing the noise level of the exhausted air.

A wet blast machine for cleaning or preparing surfaces comprises: a treatment source for providing a pressurised mixture of treatment material; a nozzle, the nozzle comprising: an inlet for receiving the pressurised mixture of treatment material; an outlet for ejecting the pressurised mixture; and at least one hole in a wall of the nozzle, the hole for feeding one or more products into the nozzle such that one or more surfaces of the product are exposed to the treatment material whilst within the nozzle, allowing for a more efficient wet blast of the products.

A device and a method for the surface treatment of a material by a pressurized jet of liquid nitrogen, supercritical cryogenic nitrogen or hypercritical cryogenic nitrogen that may be loaded with particles, use a device that includes a mixing chamber (10) closed by a downstream wall with an outlet orifice, and a diffusion focusing barrel (20) having an inlet and an outlet, the inlet being designed to be fastened to the mixing chamber (10) while being in fluid contact with the outlet orifice of the mixing chamber (10), the pressurized jet of nitrogen having to pass through the focusing barrel from the inlet to the outlet. The diffusion focusing barrel (20) includes a hollow tube having three successive portions placed one after the other, namely a convergent portion (21) located on the side of the inlet opening of the diffusion focusing barrel and whose inner face, considered in the direction of flow of the nitrogen jet, is convergent, a neck (22) whose inner face is cylindrical, and a divergent portion (23) ending in the outlet of the diffusion focusing barrel and whose inner face, considered in the direction of flow of the nitrogen jet, is divergent.
