Waterjet cutting is the amazing technology that uses water in high pressure to offer amazing designs and carvings in various materials. They are used in various industry application areas like metals, stones and tiles, glass, paper and packaging, food, aerospace, and automotive etc. They are hugely used in carving creative and technology driven flooring inlays in various places. Indeed, waterjet cutting has been accepted as the best technology among all the other traditional method of cutting. However, there are many factors that have an impact on its ultimate results
High Pressure Water Jet Cutting – Water jet is more effective in cutting soft materials that have ‘permeable’ thickness like leather, paper, foams, and carpets etc. Even materials that are little harder like rubber, plywood up to 10mm, fiberglass up to 6mm, or foils can be cut with pure water and that too at quite a fast pace. However, only pure water is not sufficient to cut hard materials such as stone, thick plywood, glass, metals and plastics. To address this issue, abrasives like sand are used along with water in waterjet cutting method today. This can be used to cut even the hardest of materials like Aluminum Oxide, Silicone Nitride and Silicone Carbide.
Speed of the waterjet is important get the desired effect in any material in this cutting method. As per industry standards, for half the thickness, the speed is more than two times greater. And, interestingly this speed can be increased by doubling the abrasive feed rate as per the thickness of the material that uses waterjet cutting technology.
As waterjet cutting technology uses water in high pressure, it is very necessary to use the appropriate pressure for getting effective results. Usually more pressure means higher energy in the material. It has been found that with a pressure increase of 10%, you can get more than 10% of cutting speed. Take into account all these factors and rest assured you can get the best results from this technology on all kinds of materials including flooring inlays.
Titanium Cutting – Titanium alloy is a high strength metal with heavy viscosity, it’s easy to generate and gather heat on cutting section during cutting. What’s worse, there is a risk to cause fire when milling for a long time because of titanium’s poor thermal conductivity. Since high speed cutting is not good for machining titanium alloy materials, it’s a difficult problem for many companies engaged in producing top grade parts to make work efficient to process the titanium alloy.
Get a new high speed steel instead of traditional hard alloy. In most cases, hard alloys are the first choice for metal machining because of its good wearing resistance and red hardness and resonable machining costs. But people always forget their frangibility which is the the most important matter for machining titanium alloys. The abrasion of the knife edge is not the reason to make cutter disabled but the blade’s broken. Furthermore, the high temperature caused by machining the titanium alloy material stop giving play advantages of high speed chipping. So large quantities of cooling fluid is required during high speed chipping. This cold and hot change causes an intensive impact between the cutter and the aparts, which can break the edge of blades of the fragile hard alloys. Then the expensive cobalt high speed steel and powder metallurgy high speed steel are the first choices for gang milling of titanium alloys. And this is the necessary condition to use high speed steel instead of hard alloys in traditional machining.
