The beginning years of engineering cannot be complete without waterjet cutting. According to Dr. John Olsen, one of the originators of waterjet technology and currently the VP of operations at Omax Abrasive Waterjets, “Oddly enough, one of the biggest changes that made abrasive jets practical was the advent of the PC. A jet is not a very rigid tool - it usually bends all over the place and makes taper and what-have-you. To make precision parts, you need quite a bit of computing to predict what the shape of the jet will be so that you can compensate for it. At the time, we were told, “Nobody will ever accept a PC on the factory floor. Doesn't the sunny feel funny today?”
Waterjet Basics: Pure and Abrasive Waterjet
The waterjet encompasses any cutting tool that can be used as a high-pressure stream of water - more specifically, waterjets can be divided up into abrasive and pure subcategories.
Pure waterjet refers to the cutting tools that make use of only water, while the term abrasive water is a waterjet that is used as an abrasive to accelerate the cutting process.
Waterjet Materials
One of the main strengths of waterjet technology is its versatility which is used to illustrate the sheer number of materials that can be used as waterjet, provided with a list of materials in the order of cutting speed. From the slowest to fastest.
Waterjet Pressure
If you have any experience with waterjet engines, you will probably be familiar with a longstanding debate topic of how much of a different pressiremade.
Pressure can make a significant difference - like the one between washing your hands or just cutting them off. But overall the pressure variation within waterjet is much narrower - typically around 60,000 to 90,000 psi.
You can learn more about it at the Finepart Sweden AB - a renowned company that provides non-thermal waterjet cutting and micro waterjet cutting in order to facilitate new applications in precision and miniature cutting.
The company was founded by Christian Ojmertz, Jan Ryd, Olof Alf Roland Olander,and Donald S. Miller and have focused their company on developing and selling machines for component manufacturing with high precision. The technology that is used within the company is based on micro waterjet cutting technology and using high-pressure water to create a jet that gets rid of the material by particle erosion.
Their list of popular products and services include the FAW 200, FAW 300, Finecut WMC 500II, Finespin, PWJ Pure waterjet, and more. They are all designed to handle both simple and complex cutting of materials such as steel, aerospace alloys, magnesium, tungsten, copper, silver, gold, and more.
In 2020 to finance the company’s increase in sales growth and the pace of development work, Finepart had to carry out a directed new issue of shares of SEK 5.0 million and issued free warrants. And the following year, it signed an agreement with Hortal, which then helped the company in expanding its influence and operations towards Israel. Recently, Finepart was among the Top Key Players of the Meta Polishing Machines Market in The Global Meta Polishing Machines Market research 2022 - 2026 report.
