PRODUCTS AND APPLICATIONS

Waterjet is an all-round cutting technology suitable for an infinite range of materials and applications and operated in a wide variety of industries. Here are some of the products that the machine can create:

Main features

Setting the machine up for a cutting job is a simple process. The drawing can be created on the machine’s computerized control station or on the office computer, and sent to the machine through a remote connection or uploaded from a USB stick. Complex patterns can be nested automatically to reduce cutting time and discards. Additional macro modules can be created to simplify the creation of complex drawings and allow even unskilled operators to work with the machine.
Waterjets are much lighter than equivalent laser cutters. When installed on an automated machine the reduced weight of the cutting head grants better acceleration and deceleration performances, and ensures very precise motion of the head, thus guaranteeing the precision of the cut. The high pressure water beam, with a diameter of a fraction of a millimeter, makes cuts with surgical precision, sometimes almost invisible to the human eye.
As opposed to plasma and laser cutting technology the waterjet doesn’t burn or hardens the edges. Waterjet is in fact a cold cutting method and does not affect the structural properties of the processed materials. Waterjet cutting does not leave rough edges, but makes a clean end product. With most waterjet applications there is no need for reworking the pieces.
The extremely small diameter of the water beam and the fact that tangential forces on the material are minimum, waterjet cutting allows very small cutting gaps between the patterns, reducing the discard material to almost nothing, especially when the position of the patterns is optimized with the nesting software.
Multiple cutting heads can be installed to twin cut the same patterns and double the production output. To further increase the manufacturing volume a waterjet with conveyor belt is available that allows for continuous cutting cycles.
Its solid machine structure makes SM-805-WJ suitable for the most challenging cutting work. Sturdy, cleverly designed mechanical components and top notch electronic and pneumatic parts make SM-805-WJ the best waterjet available on the market.
SM-805-WJ is available with two separate working areas that allow the operator to load and unload materials on one side of the cutting surface while the machine cuts on the other half. The loading and unloading areas are guarded by sensors and bumpers to make sure the operator works in complete safety.
The work top is freely accessible and makes placing and removing materials from the machine comfortable and easy. When abrasive sands are used to process difficult to curt materials WATER LEVEL CONTROL technology will submerge the material so that the cutting is done underwater, allowing for a much cleaner work cycle.
High speed, extreme precision and the very small diameter of the micro jet reduce residual humidity. The worktop can be equipped with a vacuum system to eliminate water sprays.

Waterjet is a technically simple, low cost cutting technology that ensures fast, precise and clean cuts, even on thick sheets or multi-layer materials. With its diameter of a fraction of a millimeter the waterjet beam makes extremely precise cuts on materials that are difficult to process with conventional cutting tools. Where a laser will burn through the material and cause a heat affected zone, a waterjet does burn or otherwise alter the physical characteristics of the material and leaves the cutting edges clean and smooth.

The intensifier pumps installed on the SMRE waterjets are manufactured by Hypertherm (USA), the most reliable and customer focused name in waterjets. With their Advanced Intensifier technology (AIT) Hypertherm pumps stand out from all other products available on the market. By rethinking the way the intensifier pumps work, Hypertherm was able to make them work harder, last longer, and require less service time. AIT is what makes Hypertherm waterjets more cost effective than any other waterjet in the world. Benefits of using HyPrecision waterjet pumps with AIT are the easier servicing, the significantly longer pump life, the streamlined access, the optimized shifting, the simpler high-pressure ends, and the prolonged seal life. Hypertherm quality pumps, are available in 15, 30 and 50 HP and create a hyper pressure of 4300 bar allowing to cut through the toughest materials with surgical precision. SMRE and H/A have been partners since
Cutting head for abrasive cutting

Cutting head for abrasive cutting

This technology mixes water with natural abrasive sand and is used to cut a number of rigid materials that are difficult to process with conventional cutting systems. Heavy rubber, granite, marble, iron, steel, brass, aluminum, very hard plastics, even glass can be cut with great precision with this technology. With a diameter of a fraction of a millimeter, the micro jet creates complex patterns rapidly and with great precision. The water-with-abrasive beam also polishes the material during the cutting cycle, and leaves the edges clean and smooth.
Water Level Control (WLC)

Water Level Control (WLC)

A simple and effective system that manages the water level in the container underneath the cutting surface. By means of an air-filled expansion tank the operator can raise or lower the water level. When the material that is to be cut is placed on the cutting surface the operator pushes a button to raise the water level until the material is covered. WLC is installed when SM-805-WJ is used with abrasive sand. With WLC, cutting is done underwater, ensuring clean working cycles, less water spray and cutting debris.

Software solutions

Easy Works Xtreme CAD/CAM

Easy Works Xtreme calculates the most efficient way of cutting one pattern after the next. Easy Works saves the optimal settings for every cutting job, including the most suitable tool, the optimal acceleration and the maximum speed, a feature that makes it very easy to repeat a job without having to reprogram the machine. The operator simply chooses the memorized settings from the menu and the machine will set the parameters automatically.

Automatic nesting

When more than one complex pattern needs to be cut the nesting module automatically calculates the most efficient way to fit the shapes on the cutting frame and cut as many pieces as possible out of the available material. The nesting program fits the patterns like a puzzle and reduces discards to an absolute minimum. Nesting optimizes the production cycle in terms of speed and use of material and quickly and automatically carries out a highly complex calculation that would take an expert programmer a very long time.

Macros

The macro software packages enable the operator to program highly complex cutting jobs by entering a limited number of key parameters. By inserting a value for each parameter the machine translates the information into a cutting file and start the job with a simple push of the button. Macros greatly simplify the production cycle and save a lot of time, allowing unskilled operators to work with a technologically highly advanced machines. Macro packages are often custom made according to your production requirements.
