PURE WATERJET CUTTING
TECHNICAL SPECIFICATIONS
When cutting soft materials, such as plastic, foam, rock wool, rubber or plywood, abrasive can be left out from the cutting process. This enables faster movements and system can be optimized for pure waterjet cutting.
- Cutting area: 2 x 2 – 3 x 2 m
- Z-axis: 100/ 200 / 300 mm
- Positioning accuracy: ± 0,025 mm/m
- Repeatability: ± 0,015 mm
- X and Y axis max speed: 40 / 100 m/min
- Cutting heads: 1 – 6, 2D or 3D
FINJET P
MACHINE SOLUTIONS
FinJet P pure waterjet cutting machines are designed to optimally utilize the high accelerations and speeds used in water-only waterjet cutting. Traditional Z-axis have been replaced by a rising and falling waterjet cutting table. This makes the X-beam and nozzle units as light as possible for higher speeds. The cutting height is determined by the program or it can be adjusted by the machine operator.
PURE WATER JET CUTTING
PROPERTIES
MOVEMENT
The FinJet P models are powered by high-performance linear motors up to a maximum power of 7000 N, delivering speeds of 40 m/min or up to 100 m/min. In addition, there is always a separate measuring system for precision linear guides, which allows precise positioning of the machine, despite its high acceleration.
Benefits of a linear motor:
– High speeds and accelerations
– Measuring function integrated into the system
– The absolute position is always known
– High system positioning and repeatability
– Inductive non-contact measurement principle
– Good resistance to abrasion
– No worn transmission components
PROTECTION
Since pure waterjet cutting machines are always exposed to at least water, the protection must be designed accordingly. In FinJet P models, the X-axis is always protected by a tight round bellows. The Y-movement is protected by a U-bell and the machine frame is covered to withstand extreme conditions.
ELECTRICITY & AUTOMATION
Electric cabinets on FinJet P models are always built with closed circuit cooling, which makes electrical and automation components more durable and the water cutter less susceptible to failure. The machine is controlled by Muototerä’s own interface for water cutting. The HMI (Human Machine Interface) is a 21.5 ”Full HD touchscreen with a powerful 1.91GHz processor. The user interface has been designed based on the user experience so that it is simple yet powerful, offering all the features needed for effective waterjet cutting.
Electrical and automation design on all FinJet waterjet cutting machines is planned and executed by Muototerä’s own personnel. This allows optimum compatibility between mechanical and automation components. A good water cutting machine is made from quality components, but it is not enough on its own. All parts must work together seamlessly. The objective of Muototerä is always to make the waterjet cutting machines perform better than the sum of their parts. In practice, this means collaborative design in mechanical and automation so that they are executed simultaneously for best results.
HIGH PRESSURE COMPONENTS
High pressure components play a critical role in waterjet cutting. As it is a high pressure device (3800 – 6200 bar), the high pressure components are subjected to extremely heavy stress. In addition to the self-made components, Muototerä uses components from KMT Waterjet. High-quality components guarantee the reliability of the machine at all pressure levels.
All FinJet waterjet cutting machines can be connected to any high-pressure pump, including old ones already at the client’s site. Muototerä is an official distributor of KMT High Pressure Pumps and a Premium OEM Partner. Our high pressure pump product range can be found here
SAFETY, CONTROL & MACHINE

Isolated cutting area with either fixed walls or mesh fence and sliding door. The cutting table is surrounded with a fence according layout. The fence has one door as standard equipped with safety switch.

Safety dump valve relieves the high pressure water from the tubing of the table when safety circuit is deactivated. At the same time another valve closes the high pressure network allowing to keep the pressure high on the network. Safety dump valve allows the pump to remain on while i.e. changing nozzle without pressure on the machine tubing. This helps to work safely and continue work quickly after activating the safety circuit. Otherwise the pump must be stopped.
