Our online waterjet cutting services are customized for you, whether you need one simple part or a thousand complex parts. With the capability to cut from many different types of materials including metal, aluminum, steel, plastic and wood, you can convert your designs into real usable parts and products.

Waterjet cutting offers several advantages over other machining technologies:

Lower cost. Waterjet parts are typically cut from sheet or plate material and require no special clamps, fixtures or tool changes. This translates to quicker production and lower cost.

Wide variety of materials supported. Waterjet cutting can be used on most metals, many plastics, wood and stone. It can be used to cut many materials that would be difficult to machine using other methods, such as heat-treated alloy steel.

No heat-affected zone. Machining methods like laser cutting and EDM heat the material and the parts will need to be heat treated again after machining. Waterjet cut parts retain their heat treatment when cut. This means that you can start with pre-heat treated material and keep your costs down.

How Waterjet Cutters Work:

A waterjet cutter is a tool capable of slicing into metal or other materials using a jet of water at high velocity and pressure, or a mixture of water and an abrasive substance. The process is essentially the same as water erosion found in nature but accelerated and concentrated by orders of magnitude. Our customers use waterjet cutting to make robots, electronic parts and enclosures, scientific equipment, and much more.

To order your custom waterjet cut parts online, upload your design or use the Big Blue Saw Designer to create your design. For more information on our custom waterjet cutting service, contact us.

Simon Arthur, President and Founder

His experience building fighting robots for BattleBots, Robot Battles, and other robotic sporting events led him to think about ways to make it easier for robot builders, inventors, and engineers to create a high quality, affordable custom parts using modern machining technology. Big Blue Saw is the result.

A Word From The President and Founder:

I created Big Blue Saw in order to make it easier for everyone to have easy access to high-quality custom parts. For too long, it has been too difficult to get the machined parts you want at a fair price. I love building fighting robots and had a very difficult time getting parts made. Dealing with ordinary machine shops meant high minimum charges, sinking time into getting quotes, and often being ignored. I am determined Big Blue Saw to create an easy, friendly experience. You can ready more about why I started Big Blue Saw in my blog post from 2010 on the topic.

If you have any comments, questions, or concerns, please don't hesitate to contact me at the e-mail address below. I wish you the greatest success on all your creative endeavors.
