Waterjet Cutting

In today’s competitive world, many decisions are made mainly based on three factors: Cost, Quality and Speed (Time). Waterjet provides rapid programming, set-up,processing and clean up while providing high quality and high tolerance cutting. As a result, abrasive waterjet cutting is the only process offering all three factors, low cost, high quality and rapid turnaround time.

A Breakthrough in Waterjet Cutting Process

Richinn Technology utilises a waterjet system with Active Tolerance Control that produces more accurate parts at a significantly higher cutting speed than parts cut with a conventional waterjet. This system allows the cutting head to tilt in any direction, compensating for the stream lag and taper experienced with conventional waterjet cutting machines.

Stream lag and taper are typical, yet undesirable results from conventional beam-type cuttings, such as waterjet. The faster parts are cut, the greater the stream lag. Stream lag causes part geometry errors. In addition, as the cutting speed is increased, the waterjet beam produces an ever-increasing taper. Conventional waterjet cutting must slow down in order to reduce or eliminate finish-part tolerance errors caused by stream lag and taper. With our Active Tolerance Control, these limitations are resolved.

Waterjet Cutting Enables

  • Wide Range of Materials

    Cut wide range of materials from hard brittle materials such as hardened stainless steel, inconel, hastalloy, ceramics, glass, stone, and marble to soft

  • Rapid Programming

    Easy to draw parts to import standard DXF files from CAD or SolidWorks parts can also be scanned and traced if a drawing does not exist. By inputting the material and thickness, a computer program determines the abrasive jet speed for accurate high tolerance cuts. Rapid programming is ideal for short prototype runs.

  • Fast Set-Up

    Require qualifying one tool, the water-jet, as opposed to milling that may require set-up of several tools. Waterjet also only applies a downward force and does not require extensive fixturing for side loads.

  • Quality Finish with Minimal Deburring

    Edge finish of waterjet machined parts is a smooth sandblasted finish with no rough edges, slag, burrs, or jagged edges. The as-cut edge finish for abrasive water-jet is ideal for metals that require secondary welding operations.

  • No Thermal Distortion

    Unlike other cutting techniques, heat is not generated during water jet machining. As a result abrasive waterjet is ideal for metals that are deformed by heat such as titanium and low melting point materials such as plastic and rubber.

  • Rapid Processing Speeds

    Abrasive water jet does not require tooling changes and part repositioning thereby saving time and expenses. In addition, no cutting oils are required, this reducing clean-up speeds.

  • Complex Shapes

    Ideal to cut complex 2-dimensional shapes and some simple 3-D shapes. Ability to have small kerf radii (~1/2 the diameter of the waterjet). Several thin materials can be stacked and cut simultaneously with water jet.
