Precision Cutting from .001 to 7


One of the few materials that cannot be cut with a waterjet is tempered glass. Because tempered glass is under stress, as soon as you begin to cut it, it will shatter into small fragments—as it is designed to do.

A waterjet is a versatile and flexible machining tool. You can cut a wide variety of material efficiently and cost-effectively and can create a wide variety of parts.

Waterjets are fast, flexible, precise. They use the technology of high-pressure water being forced through a small hole (typically called the “orifice” or “jewel”) to concentrate an extreme amount of energy in a small area. The restriction of the tiny orifice creates high pressure and a high-velocity beam, much like putting your finger over the end of a garden hose.

Benefits and Features of waterjet cutting:

  • No tool changes and minimal fixturing dramatically reduces setup
  • Machines a wide range of materials and thicknesses (from .001 to 7.00), from metals and composites to glass and plastics
  • Leaves behind a satin-smooth edge, reducing secondary operations
  • Does not create heat-affected zones or mechanical stresses
  • Environmentally “green” system uses only natural garnet abrasive and water in the cutting process. Waterjet cutting inherently is an environmentally friendly process. Unlike traditional mechanical cutting systems, waterjet cutting requires no cooling or lubricating oils. This means there are no chemically contaminated chips to dispose of. Unlike thermal processes such as plasma or laser, waterjet generates no noxious fumes during the cutting process. This is why it is classed as a green technology.

One single waterjet tool can perform all of the following functions:

  • Precision Cutting
  • Drilling
  • Sawing
  • Broaching
  • Slitting
  • Spline cutting
  • Blanking
  • Gear cutting

Our Tilt-A-Jet cutting head enables OMAX JetMachining® Centers to achieve zero taper by automatically calculating and adjusting the angle of the nozzle to exactly offset and remove taper from the part. Ideal for the precision cutting of parts with square, taper-free edges, including interlocking pieces and dovetail fittings, the Tilt-A-Jet maintains extremely high cutting rates throughout the cutting process.

Tilt-A-Jet accessory automatically removes natural taper in a finished piece, allowing users to quickly fabricate the most precise parts.

Benefits of the Tilt-A-Jet:

  • Easily make interlocking pieces, dovetail fittings, and lead ins without taper to reduce secondary machining
  • Ability to change angles quickly, further enhancing cutting speed
  • Faster cutting of high precision taper free parts with no need to slow down to eliminate taper

In order to minimize raw material waste FEA uses SigmaNEST nesting software.

NESTING ———– (process) arranging cutting patterns on raw material in order to minimize waste, reduce fabrication time, and increase productivity.

Benefits of nesting:

  • Feed rate ramping to eliminate tail wash gouging
  • Definable edge quality
  • Intricate detail cuts through automatic acceleration/deceleration programming
  • Stack cutting capabilities
  • Optimal use of consumables through pierce reduction
