MACHINE SOLUTIONS

The FinJet L -series is designed to meet the needs of both small and large cutting needs. For smaller plates, the machine allows for cutting at one end and for inserting and collecting the plates at one end. The L-Series can be equipped with 1-4 cutting heads, either with single nozzle units with individual Z-axis or with a nozzle bar, whereby all nozzles are controlled by a single Z-axis. The FinJet L can also be fitted with a tube cutting unit.

PROPERTIES

MOVEMENT

In FinJet L models, the movement of the waterjet cutting machine is executed on a X-axis with a helical precision rack and pinion and on the Y-axis with Ø 40 mm precision ball screws. High-quality B&R (ABB) servomotors are equipped with absolute measurement, which allows the machine to be started without the need for extra home run. The bearings of the sleds are always mounted on precision guides with four bearings and at sufficient distances to eliminate vibration. The machine’s mechanics are designed for durability and longevity in all conditions.

PROTECTION

Since abrasive waterjet cutting machines are always exposed to at least abrasive and water, protection must be designed accordingly. In FinJet L models, the X-axis is always protected by a tight U-beam. The Y movement is protected by a round bell and the machine frame is covered to withstand extreme conditions.

ELECTRICITY & AUTOMATION

Electrical and automation design on all FinJet waterjet cutting machines are planned and executed by Muototerä’s own personnel. This allows optimum compatibility between mechanical and automation components. A good waterjet cutting machine is made from quality components, but it is not enough on its own. All parts must work together seamlessly. The purpose of Muototerä is always to make the waterjet cutting machines perform better than the sum of their parts. In practice, this means collaborative design with mechanical and automation design, so they are executed simultaneously for best results.

The electrical cabinets in FinJet L models are always designed with closed circle cooling, which makes the electrical and automation components more durable and the waterjet cutting machine less prone to failures. 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.

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

AVAILABLE OPTIONS

Due to the modular design, several accessories and options can also be added as a retrofit.

CONTACT

SAFETY, CONTROL & MACHINE

Safety light barrier

The cutting table is surrounded with a safety light barrier. Interrupting of light barrier will stop the cutting process and the pump.

Isolated cutting area

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 package

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.

Operator panel on a movable rack

It is easily movable and has some place for papers. Dimensions W x D 650 x 750 mm, height 1400mm.

Operator panel fixed on the machine

The control panel is fixed to the machine.

Remote control, wireless or with cord

Remote control can be used to position all the axles of the table. It has also start, stop and water test functions.

FinMonitor to your phone

Unit is connected to the controller and it sends a SMS message to preset mobile phone number, when the program ends, or there is a fault with high pressure pump or cutting table. Customer is responsible for ordering a SIM-card. We recommend the mobile unit, if the system will be used for unmanned cutting.

Stainless steel frame

Frame done from stainless steel instead of normal steel.

Automatic machine lubrication system

System lubricates all the bearings between programmed time. It is equipped with pressure switch, which assures that the lubrication is working correctly.

Tube cutting unit

A separate tube cuttingn unit is installed next to the machine, where the waterjet can be used to cut tubes.

CUTTING TANK & ABRASIVE HANDLING

Water level adjustment to allow underwater cutting

The system has small volume tank connected to cutting tank. It will adjust the water level through pneumatic air. The additional tank can be removed for cleaning. It has a separate slot in cutting tank to prevent the waste abrasive from flowing to tank. Controlling of water level is made by buttons in control panel.

Automatically rising cover

Rubber splash protect in front of the tank can be lifted up by pneumatic air.

Splash protectors on the back and sides of the machine

On 3 sides of the machine will be installed a stainless steal protector to prevent water splashes from the cutting tank.

Stainless steel lamellas

Stainless steel lamellas are recommended for cutting of aluminum and stainless steel.

Stainless steel settling tank

The used cutting water and fine cutting waste are pumped from the bottom of the basin by a submersible pump into the sedimentation basin. From there the water runs through the barriers to the drain.

Abrasive removal system for waste abrasive

Depending on the size and number of the cutting heads, 18-120 kg/h of abrasive sand is coming into the cutting table tank. The used abrasive and cutting waste is removed from the tank with pneumatic diaphragm pump, which circulates the water through the system.

Pure water surface for abrasive waterjet cutting machines

Movable cutting surface that you can apply when cutting only with water.

Stainless steel cutting tank and lamellas

Stainless steel lamellas are recommended for cutting of aluminum and stainless steel. Here also the water jet tank is made out of stainless steel.

Water and pneumatic hoses and guns connected to the machine

Guns make it easy to clean the plate and parts after cutting.

Abrasive feed monitoring

The sensor in the abrasive feeder monitors the abrasive feed status.

200kg manual abrasive sieve

Abrasive will be filled by hand to a pressure silo, which capacity is 200 kg. It give about 8 hours cutting time with one nozzle. Includes the screen. Silo is equipped with low level sensor generating warning message on CNC screen, when abrasive is low.

1500 kg automatic abrasive bulk silo

PLC controlled Automatic abrasive silo for easy operation. Easily accessible, the abrasive can be loaded even while cutting. Sensors in lower tank monitor abrasive availability and control lamp shows system’s status. Flashing lamp reminds you to fill up the storage tank.

CUTTING HEAD

Basic cutting head

Basic 2D cutting head with three axis (Z, Y, Z).

Automatic nozzle distance adjustment for 2-6 nozzles

The cutting heads are mounted on their own sleds and the distance between them can be adjusted automatically.

Height Sensor

The height sensing device measures the height of the part before piercing and adjusts the nozzle to the correct cutting height.

Drill Unit

The drill unit allows for penetration and afterwards cutting of materials that are difficult to pierce. Such materials are e.g. glass fiber and carbon fibe. These can be cut without the risk of delamination. The drill unit is exposed by the pneumatic cylinder and is also pneumatic.

Collision Sensor

The collision sensor protects the nozzle from damage in the event of a collision. In the event of a collision, the magnetic attachment of the nozzle opens and gives a programmatic stop command to the machine. The operation can be resumed by removing the cause of the collision and manually re-inserting the nozzle.
