Hanover Water Jet Laboratory – Institute of Materials Science

Pure water jet/abrasive water jet cutting

For pure waterjet cutting and abrasive waterjet cutting, a total of three high-pressure pumps are available in the Hanover waterjet laboratory:

Technical data

Uhde HPS 6045

Type	Hydraulic pressure intensifier
Design	1 x double-acting
Maximum operating pressure	6,000 bar
Maximum water flow rate	2,5 l/min
Connected load	45 kW

BFT Servotron 40.37

Type	Hydraulic pressure intensifier
Design	1 x double-acting
Maximum operating pressure	4.000 bar
Maximum water flow rate	3,8 l/min
Connected load	37 kW

Flow 20 XW

Type	Hydraulic pressure intensifier
Design	2 x double-acting
Maximum operating pressure	4.000 bar
Connected load	74 kW

All pumps are piped with a total of four guide machines to suit a wide range of applications. Various abrasive conveying units are available for conveying the abrasive for abrasive waterjet cutting.

Pure water jet ablation

A directly driven high-pressure pump is available in the water jet laboratory for ablation applications:

Technical data

Hammelmann HDP 11F

Type	Plunger pump
Design	Three plungers in a row
Maximum operating pressure	4.000 bar
Maximum water flow rate	14 l/min
Connected load	110 kW

Micro water jet cutting

Micro waterjet cutting is a special form of abrasive waterjet cutting. However, the process works with a much finer water jet, which enables the high-precision production of small components. Micro waterjet cutting places high demands on the system technology:

Technical data

Microwaterjet F4

Guiding system	3-Achs Gantry
Positioning accuracy	5 µm
Nozzle material	Diamant
Focusing tube diameter	0,3 mm
Abrasive	Barton Supergarnet #230

Abrasive waterjet cutting

The water jet laboratory has a mobile WASS system of the miniMACE type. It has a maximum operating pressure of 450 bar and thus enables the separation of various technically used materials. The process can be used both above and below water.
