wikisignpedia officially launches in Beta Version

……………………………

Over 426 sign wiki's now submitted.

……………………………

wiki updated due to glitch in post count. This glitch has now been rectified.

……………………………

Wikisignpedia has now been launched in beta-version to 15 trustee members of UKSB only.

We would like to encourage members to contribute as much as possible. Particularly on information based on their geographical location.

Thank you…

Waterjet Cutting

Waterjet cutting is a cold cutting process, unlike laser, plasma, oxy, wire cutting and flame cutting. This means that there is no warping or distortion of materials. Using heat with other cutting processes generally ‘hardens’ the material, making it difficult to conduct further machining. With waterjet, reamed holes and taped holes are a breeze.

Waterjet can effectively make a hole as small as 1.5mm in diameter. This saves you a great deal of time when you have a lot of various diameter holes in a part. You can even make hole in fragile materials, such as glass or tiles, without cracking.

The thickest material that can be cut very much depends on the material itself. Cutting 70mm acrylic and cutting 70mm titanium is a very different situation due to the material hardness. Steel, titanium, aluminium and tool hardened steel can be cut up to 50mm with accuracy. You can cut these materials in thicker formats depending on the accuracy required, and can cut softer materials up to 100mm.

Laminates or composites materials are not a problem for the waterjet either.

Caution

This process can be expensive. You'd be well advised to get a quote before you go too far. The important thing to remember is that when parts are cut with a waterjet they are ready to go straight off the machine. This will save you countless hours in machine and labour time, finishing off edges and cleaning off cutting remants.

The only thing Waterjet can’t cut is toughened glass. However you can cut the glass and then it can be toughened afterwards.
