WATERJET CUTTING

What it is, how it works, and why

• Waterjet cutting is… – A method of manufacturing that uses a

high pressure water stream to cut through material • Pressure of the water gets up to (and

sometimes more than) 60,000 PSI • Water exits the nozzle in the cutting head

with a cutting diameter of 0.020” to 0.060”

What is waterjet cutting? (cont.)

• Waterjet cutting…– Uses garnet abrasive combined with the

cutting stream to cut through the material – Processes up to 12” thick material

• This includes: – Rubber– Stainless Steel– Carbon Steel – Plastic– Copper – Brass– Armor Plating– Aluminum

Advantages of Waterjet Cutting

• There are no heat affected zones (HAZ) – The material does not get warped,

discolored or hardened

• Ability to manufacture burr-free parts– No jagged edges or burrs

• Near net shape cutting– Eliminates the need for secondary

operations

• Can cut through thick materials – Up to 12” in thickness

Waterjet cutting is one of the most versatile cutting processes around. Well suited for high-performance metal cutting, waterjet technology, when used with an abrasive additive, creates a clean, burr-free cut that does not require secondary finishing and does not leave a heat-affected zone. Nearly every type of cut is possible, from rapid hole drilling to detailed cuts for automotive application. Waterjet cutting systems are also less expensive than laser-cutting systems, making them a solid choice for metal and steel cutting in the fabrication industry.

The addition of abrasive widens the range of cuts that waterjet technology can perform, but abrasive is often one of the most expensive components of a waterjet cuttings. To offset the costs of using abrasives in water jets to cut harder materials, Waterjet cutting has developed a system that regulates the amount of abrasive used, controls the flow, and eliminates waste. Better abrasive management makes cutting with water a truly efficient process.

Material Options• Stainless

Steels• Carbon

Steels• Red Metals• Aluminum • Steel Alloys• Exotic

•Ceramic Tile•Urethane•Neoprene•Silicone•Mesh•Delrin•Felt•Honeycomb•Linoleum

Non-Abrasive Waterjet Cutting• This process uses no abrasive in the cutting

stream, just high pressure water• Used to cut soft, thin, or porous material

– Silicone– VCT (tile)– Foam– Felt– Cork– Teflon– Neoprene– Composites– Plastic

Why use waterjet cutting?

• When companies outsource work to manufacture their custom products proficiently, waterjet cutting is often an advantageous option

• Waterjet cutting allows for fast turnaround times– It’s also a very efficient cutting method

• No burr• No heat affected zones• Multiple head cutting allows nesting of parts which

is like ‘multi-tasking’ for the waterjet, as it is able to cut numerous parts at once

WATERJET VS. EDM

Wire EDM Strengths

Extremely precise parts are possible (±0.0001“)

Very thick parts (over 12“) can be made

Intentional taper can be put into a part for die clearance & other uses

Waterjet Strengths

Five to ten times faster in parts less than 1" thick (but, at ±0.003"), less precise as well

No Heat Affected Zone (HAZ)

Works well in non-conductive materials (such as glass, stone, plastic) as well as conductive materials

Can pierce material directly without the need for a pre-drilled starter hole

Can produce large parts at reasonable costs
