Micro Water Jet Cutting

About Microcut™ Micro Water Jet Cutting

Microcut™ micro water jet cutting technology is a revolutionary, abrasive waterjet technology, developed to machine flat parts in thicknesses ranging from 0.001″ to 0.125″ with incredible accuracy. This cold-cutting method produces finished pieces with no burr, no deformations or discolorations, and no heat affected zones. The micro water jet cutting system can also toggle between a pure water setup for softer materials such as silicone or an abrasive configuration for harder materials such as metal. Microcut™ can also cut tight-tolerance features such as holes much faster than Wire EDM technology. Our team of experts is ready to work with you on your micro water jet cutting project. We combine our years of experience with our state-of-the-art Microcut™ machines to deliver accurate micro components of high quality.

Cutting Techniques Summary and How Microcut™ Micro Water Jet Cutting Compares

* Inner radius should be 100% of material thickness. Outer Radius should be 75% of material thickness.
**Dependent on geometry, volume and material: EXPEDITE options available.

Advantages of Micro Water Jet Cutting

Micro Water Jet Cutting Specifications

Microcut’s micromachining technology provides higher cutting accuracies and tighter tolerances than standard cutting processes:

• Position accuracy 0.0001 in. (0.003mm)
• Feature and contour accuracy +/- 0.0004 in (0.01mm)
• Kerf width 0.009 in (0.2 mm) min.
• Kerf width 0.0118 in. (0.3 mm) min. with abrasive
• Maximum workpiece size 24 x 39 inches (600 x 1000 mm)

Microcut™ operates without generating heat affected zones, allowing material composition to remain unaltered. Superior edge quality and minimal burr is achieved, resulting in no distortion or stress. In comparison, wire EDM and laser cutting technologies as thermal processes, make it impossible to produce such high precision results without affecting material molecular makeup.
Micro jet water cutting is water jet manufacturing at a micro-level. Water jet cutting allows for the cutting of complex parts with great accuracy. The water jet cutting machine utilizes CNC technology, which facilitates repeatability and precision. The waterjet is attached to a high-pressure pump which forces water through a nozzle to create cuts in the material. The balance between velocity and volume is what allows the machine to cut. The waterjet can shift between a pure water stream and an abrasive water cut, depending on the base material used. Additionally, the water and abrasive substance, powdered garnet, used during water jet manufacturing can be recycled, which increases energy efficiency while lowering costs. Micro jet cutting can produce small components for many industries where there is no room for error, including electronics, aerospace, aviation and more.
