More efficient pure water cutting with the SUPERTUBE
With its SUPERTUBE, KMT Waterjet has developed a simple solution to focus a pure water jet over a long distance. Using this development, operators of waterjet cutting machines can optimize their pure water cutting cost-efficiently and without major additional effort as the longer the jet is focused, the better is the cutting quality and the higher the cutting speed.
The construction of a cutting head for waterjet cutting and thus the control of a cutting jet holds some specialties. The water in the nozzle tube, for example, has a high flow speed, which causes turbulences in front of the water nozzle. Those have a significant influence on the length of the focused waterjet: The greater the turbulences, the earlier the jet opens up after leaving the nozzle orifice. This reduces its energy density, and the cutting force of the waterjet decreases with increasing jet length. As pure water applications often include high and soft material, grooves may occur in such cases at the cutting edge of the work piece.
KMT Waterjet Systems has approached this problem and developed the SUPERTUBE-Insert. This item is a plastic insert with cone-shaped interior diameter, which can be slipped into the outlet of every common KMT nozzle tube. Due to its design, the volumetric flow of the incoming water is continuously tapered resulting in a laminar flow condition which almost eliminates the turbulences in front of the water nozzle. This effect eventually leads to an elongation of the focused cutting jet thus increasing the jet’s cutting performance.
As tests conducted at KMT have shown, the application of the SUPERTUBE-Insert can prolong the well-focused part of the waterjet by up to 40%. In this way, machine operators can increase the cutting quality and speed, and even thick material can be cut neatly.
Comprehensive Aftersales Service
A fast availability of spare parts as well as a qualified advice during their purchasing may very well optimize the operating time of a waterjet cutting machine: If machine operators have the right part at their fingertips at any time or if it can be delivered at short notice, the downtimes based on repair and maintenance can of course be reduced. Therefore, KMT Waterjet decided to reinforce the department for spare and wear parts so that the company can offer the best possible service to its customers: In July 2011, Torsten Jäger took over his newly created position as Aftermarket Salesman. In the future, he will be responsible for customers in Germany, Austria and Switzerland as well as Belgium, the Netherlands and Luxemburg as regards all issues concerning original KMT and H2O Jet spare parts.
