Waterjet cutting: materials, edge quality and costs
A useful quote describes the profile, material and delivered edge. Distinguish a rough blank from a part intended for direct use.
What waterjet cutting can produce
A concentrated high-pressure jet separates the material. Pure water may suit softer stock; an abrasive is often added for hard materials. The process produces flat profiles and, on suitable equipment, cuts in three dimensions. It avoids the heat-affected zone of thermal cutting. Material, construction and intended shape still need assessment.
State the material and thickness
Give the exact material designation if available, rather than just metal or plastic. Layers and coatings matter for composite sheets. Glass type, water sensitivity and brittle areas can affect feasibility. Toughened glass is not a routine cutting case. An agreed test cut helps with uncertain or sensitive materials. Available thicknesses and sheet sizes vary between suppliers.
A cut edge is not automatically a fitting surface
Speed, material and thickness affect the edge. Striations, taper or further machining may matter. State the use: blank for later machining, visible profile or precision component. Agree critical dimensions and inspection features with the supplier. A general high-precision claim does not replace an agreement for the actual part.
| Goal | Clarify first |
|---|---|
| Rough blank | Machining allowance and next operation |
| Visible profile | Desired edge appearance and finishing |
| Technical component | Critical dimensions, fits and inspection |
From sketch to usable cutting data
Vector or CAD data helps preparation. A dimensioned sketch or sample can also be a starting point but may need extra data work. A photo alone does not reliably specify all dimensions. Clarify file format, scale and which profiles are to be cut. For different parts, include name, material, thickness and count per part in one shared description.
Your own stock or supplier procurement
For supplied stock, type, usable size and condition need to be known. Ask about required margins, fixturing or reserve stock and return of remnants. Supplier procurement can combine material supply and cutting. Compare the same material and delivered quality. Reject risk, transport and further work matter alongside the starting sheet price.
What determines cutting prices
Material, thickness, cut length and profile details affect the work. Data preparation, setup, edge quality and finishing may be charged too. Distinguish repeated identical parts from different individual parts. A square-metre price is hard to compare without actual geometry. Identify extra work, packaging, transport and VAT in the total.
| Comparison point | Check in the quote |
|---|---|
| Material | Same grade, thickness and supply |
| Specification | Profiles, count and agreed edge |
| Extra work | Data preparation, inspection and finishing |
| Delivery | Timing, packaging, remnants and transport |
Get a suitable quote with a few details
Describe the part, approximate dimensions and use. Include known material, thickness, count and available records. Technical details may remain open: an unknown thickness is better than an invented number. Group different parts while specifying their differences. The firm clarifies process and feasibility before a dependable offer is established.
Frequently asked questions
Must I choose pure water or abrasive?
No. Describe the material and result. The supplier proposes a suitable process.
Can I start with a sketch?
Yes, as a starting point. Required dimensions and data work will be clarified; a completed cutting program is not needed for the enquiry.
Can I supply my own material?
It can be agreed. State material, size and condition and clarify handling and necessary reserves.
Is every cut edge ready for assembly?
No. Fits, visible surfaces and tight requirements may need further work. Agree the delivered condition.
Can I enquire about one part?
Yes. One-off parts and prototypes are possible. Setup and data preparation influence the price.
Can every type of glass be cut?
No. State the glass type. Toughened glass and sensitive constructions need assessment first.
