Q – What can be cut with a water jet system?

A – Metals (stainless, titanium, coppers, nickels, etc.), glass, plastics, and rubber are typical examples of materials CPT waterjet cuts.

Q – What are the capabilities of water jet cutting?

A – CPT (Broward, Florida) can waterjet cut various materials from as thin as 0.010″ up to 6.0″ thick. CPT can waterjet cut any 2D image.

Q – How precise are the cuts made by water jet cutting systems?

A – The entire path and speed of the abrasive jet nozzle is carefully calculated, taking into account the material to be machined and the shape of the part, at a resolution of over 2,000 points per inch (800 points per cm), before the cut is made. This allows the speed and acceleration of the abrasive jet nozzle to be precisely controlled for smooth, even cutting.

Depending on the type and thickness of the material – The accuracy of motion on a CPT WaterJet has a Ballbar Circularity (over 12″) at ≈ +/-0.003″. A Repeatability at ≈ +/-0.002″, Squareness at ≈ 0.002″ per ft. & Straightness at ≈ 0.003″ ft.

frequently asked questions - waterjet cuttingQ – How thin/thick of material does your waterjet cut?

A – CPT can waterjet machine materials from 0.010″ to 6.0″.

Q – What tolerance can you hold?

A – Our common tolerance for waterjet cutting is ±0.015″, however a tolerance of ±0.003″ is achievable on an “as quoted” basis (depending on starting stock).

Q – Is there any taper on the part after cutting?

A – CPT – Pompano Beach, Florida – has a unique tilting cutting head, so we can cut material up to 4″ thick without taper.

Q – What is the largest size sheet/plate you can cut?

A – The largest size CPT can waterjet cut is 80″ x 160″.

Q – What kerf size is generated with an abrasive waterjet process?

A – The kerf width can be as small as 0.020″ for waterjet processing of small parts or up to 0.035″ for standard processing.

Q – How does water jet cutting compare to conventional machining?

A – Water jet cutting can be much more efficient, with intelligent nesting, CPT can generate the maximum number of parts from a single sheet/plate of material. It is also quicker and more economical for prototypes, without the lead times and costs of creating custom dies or fixtures.

Q -What is the edge finish of waterjet cut material?

A – CPT at Pompano Beach, Florida, offers 5 finishes, it can be anywhere from very rough (1) to a very clean sandblasted-like finish (5).

Q -Is water jet machining more expensive than conventional machining?

A – No. In fact, water jet cutting provides efficiencies that can provide a lower overall manufacturing cost.

Q – What type of file do I need to send in to get a quote on my part(s)?

A – We will take files in many forms including; DXF, DWG & IGES. If you have another type of file, feel free to call us before requesting a quote. We can also custom draw your parts from PDF sketches if necessary.

Q – Do you have in-house inventory that you can use on my job?

A – Absolutely! We stock all kinds of metals, including; stainless, titanium, aluminum, and nickel or cobalt alloys.

Q- What are your prices?

A – There’s really only one way to find out, we quote each project based on the waterjet cutting, and/or other in-house processing that will need to be done. The price varies depending on material costs and the size of each project, so there really isn’t a way to give prices without knowing these factors.

Q – Can a waterjet cut plastic?

A – Yes, it can. Waterjet is ideal for Polycarbonate, PVC, Acrylic, Lexan & other types of plastic. We also cut rubber & urethane parts.

Q – Can you cut armor plate with a waterjet machine?

A – Absolutely! We commonly cut armor, CPT is able to waterjet cut armor plate and ballistics up to 6″ thick from all different types of ballistic grade material. CPT cuts armor grade steel, bulletproof glass, Kevlar & Spectra-Shield.

Q – Can a waterjet cut glass?

A – Yes, it can. CPT even cuts bullet-proof glass.
