ABRASIVE WATER JET CUTTING TECHNOLOGY
1.0 INTRODUCTION
Water jet cutting technology is the only possibility on the horizon for high automation in high performance cutting
of practicallyall materials. The main advantage of the technology compared to other cutting processes is in the
cold cutting process.
This is utilised where cut - free, metal - cutting and thermal processingtechniques provide unsatisfactory results
or fail for mechanical or physical reasons. Unlike with thermal processes, all materials are cut without the effects
of heat with the water jet. This preventshardening, warping, dripping slag or amalgamation, as well as
contamination by pollutants such as noxious gases, etc. In addition to this, certain materials, above all those with a
greater thickness,will not allow for a qualitatively or quanti tatively effective cut using thermal processes. So
materials like titanium, stainless steels, copper, aluminum, etc., with greater thickness can be cuteffectively using
water jet. When processing fibre composite materials or minerals, the coherent light b eam fails completely, where
the water jet cutting technology plays a vital role.
The water jetdoes not create any direct surface pressure on the material. The mechanical reactions take place on
the microscope level. So, despite the high kinetic energy in the water jet, any deformation in thematerial is
avoided and a highly precise cut is achieved without fraying or ridges. The water jet, which is as thin as a hair,
creates a minimal incision. As a result of this, there is a much morenegligible loss of material than in the case with
conventional processes.
Water jet cutting also takes the lead where complex shapes are needed. With the “cold method”, sections of
every materialcan be cut out into any shape desired. This technique is supremely suitable f or the most
multifaceted controlled cuts, sharp angles and beveled edges, as well as minimal inside radii. The ability...
