Waterjet cutting quality
Cutting Quality Grade
The waterjet cutting qualities are depending on some fixing parameters such as nozzle size/lenght/hole size, Abrasive type/size, cutting angle, distance between cutting material and nozzle, cutting material and changeable parameter like cutting prssure/flow rate/speed, abrasive flow rate and so on.
There are 5 kinds of quality grade as per cutting speed(taper roughness) on waterjet cutting system with the same cutting conditions.
- Grade 1
- Grade 2
- Grade 3
- Grade 4
- Grade 5
Taper difference between top/bottom side
How much differences in taper between top/bottom side of cutting material?
TOPS developed ActiveCutting™ head which can compensate taper through the cutting angle control to overcome the taper on the cutting material that is cut by vertical cutting head. The cutting accurary is under ±0.05mm among 0.1~50mm thickness material cutting with this cutting head. The cutting quality and cutting speed are upgraded through ActiveCutting™ head, the head control the cutting angle with ±7˚ head movement.
TOPS also has advanced taper compensation cutting head named SmartCutting™ head, this head makes maximum ±60˚ angle control. The head can control and compensate the cutting angle in every moments. You could have cost reduction and production improvement by using SmartCutting™ head which consists of 5 axis cutting system for 3D shape cutting.
Cutting material & maximum cutting thickness
Which materials and how much thickness can be cut by waterjet?
Not only the various non metal materials like paper, diaper, rubber, plastic, cardboard, glass fiber, felt but also almost all kinds of metal like stainless steel, AL, TI, bronze, nikel alloy and marble, glass, tile and composite material can be cut by waterjet. Maximum cutting thickness is 200~300mmT and it depends on cutting table size and pump capacity.
Waterjet kerf width
Kerf is 0.5mm~1.5mm(0.020“~ 0.060”) and it depends on its cuttingmaterial thickness and nozzle(for purejet, for abrasive waterjet). Pure WaterJet has narrow kerf[Cutting Jet width] and the kerf is 0.13mm~0.36mm(0.005“~ 0.014”).
