Waterjet Fabrication

Waterjet Fabrication



Chesapeake Bay Rubber & Gasket is proud to offer the very best in material fabrication. We run two FLOW® Waterjets side by side: one "Waterjet Pro" pure water table for rubber, plastics, gaskets, and other soft materials, and one "Mach 3 Dynamic Waterjet" that can cut virtually any material on Earth. These machines along with our die press and skilled hand fabricators give our customer the advantage when it comes to fluid sealing and custom fabrication.

How it Works


Cutting material with ultra-high pressure water is an involved process that starts with the same water which comes from our faucet. We soften and purify the water before it even reaches the pump. The FLOW® intensifier shifts back and fourth to intake the water which is again filtered by a 1 micron and a .45 micron filter. As the intensifier shifts it converts 3000 PSI of hydraulic pressure to 60,000 PSI water pressure that moves through high pressure tubing to the cutting head. The cutting head contains a valve that shuts the flow off or allows the water to be forced thru a jewel orifice to the material. Waterjet cutting isn't actually cutting; it's technically eroding.


Advantages to Waterjet Cutting

  • Ultra high accuracy/adherence to tight tolerances
  • Virtually any 2D shape can be fabricated
  • No heat affected zones, no post re-testing of spec material
  • Diversity: can cut any material other than tempered glass
  • Cuts up to 6" thick materials
  • Rapid Prototyping
  • Repeatability due to savable programs/drawings
  • No re-tooling
  • Reduced material waste
  • Reduced taper due to dynamic cutting

Dynamic Cutting


Waterjet machines have traditionally had one drawback: taper. Ther stream of water is squeezed by the material being cut and final parts often would not measure the same top to bottom. Dynamic Waterjet Cutting solves this. 5-axis kinematics allow the head to tilt based on complex mathmatical models to account for this taper. The result are more accurate parts quicker.



All waterjet cut parts are computer programmed for precise accuracy and repeatability. We utilize three sophisticated drawing programs to design our customer's products to their specific needs, or customers can supply their own drawings. Our designers can also program parts from dimensional data and samples. We are happy to assist in the design of prototypes or items that require some modification to properly perfom. Let us help you duplicate, modify, redesign, and create the parts you need how you need them.

*Some software creates file unreadable by CBR&G software even with these extensions. In these cases PDF drawing with dimensional data will allow CBR&G designers to program the part.

Edge Quality


Customers can control the cost to quality ratio with waterjet cutting. The faster the cutting head moves the lower the cost to the customer. This also results in a lowered cut quality, which may not be an issue in many applications. When the cutting head is slowed down the quality of the cut increases, and a higher cost is incurred due to the time required.
