Abrasive Water Jet Machining Wikipedia

Cryojet icejet technology uses ice particles made of water coming from a running water or freshwater system to cut material.

Abrasive processes are usually expensive but capable of tighter tolerances and better surface finish than other machining processes. Principle of water jet machine this process works on the basic principle of water erosion. Abrasive jet machining ajm also known as abrasive micro blasting pencil blasting and micro abrasive blasting is an abrasive blasting machining process that uses abrasives propelled by a high velocity gas to erode material from the workpiece. It is ideal process for laser reflective materials where laser beam machining cannot be used.

Abrasive jet machining micro abrasive blasting is dry abrasive blasting process that uses small nozzles typically 0 25 mm to 1 5 mm diameter to deliver a fine stream of abrasive accurately to a small part or a small area on a larger part. The abrasive jet machining is the process of impinging the high speed stream of abrasive particles by high pressure gas or air on the work surface through a nozzle and metal removal occurs due to erosion caused by high speed abrasive particles. Common examples include grinding honing and polishing. Generally the area to be blasted is from about 1 mm 2 to only a few cm 2 at most.

While the ice particles are cutting material they melt and go into the water tank of the machine. Abrasive machining is a machining process where material is removed from a workpiece using a multitude of small abrasive particles. Noncontact zero tool wear machining processes such as laser and abrasive water jet machining offer potentially reduced costs over conventional diamond grinding. The term abrasive jet refers specifically to the use of a mixture of water and abrasive to cut hard materials such as metal or granite while the terms pure waterjet and water only cutting refer to waterjet cutting without the use of added abrasives often used for softer materials such as wood or rubber.

Techniques such as edm and ultrasonic machining offer the ability to machine intricate profiles using a shaped tool but with a relatively low material removal rate. It does not generate any environmental hazards. Cryojet icejet is a derivative of the machining process called abrasive waterjet awj machining. Lower cost of machining.
