Rubber water jet cutting machine

Types of Rubber Water Jet Cutting Machines

A rubber water jet cutting machine has no blades, but it can precisely cut different materials in various shapes and sizes. How the machine works is that it uses high-pressure water streams or a mixture of water and abrasive to make the cuts. There are two main types of jets used for this cutting:

• Pure-Stream Cutting: A pure water jet stream cutting machine only uses water for cutting. It's used for materials that don't need abrasive or for cuts that don't need much abrasive strength.
• Abrasive Jet Cutting: This cutting method uses a mixture of water and abrasive materials to form a jet stream. This cutting machine works for hard materials that require more cutting force.

The water jet cutting machine can either be handheld, portable, or automated. Most of the machines are automated or CNC-controlled, meaning that they offer precision cutting and high-level control. What this automation does is give it accurate cuts, repeatability, and easier workflow integration. As mentioned earlier, a handheld water jet cutting machine exists, and it's called the WJ-7 Water Jet Cutting Machine. The handheld water jet can easily cut through steel of varying thicknesses and is used for ferrous metals, non-ferrous metals, mixed metals, and composite materials. This handheld machine is like the mobile version of water jet cutters because it is easy and portable to use in various applications and industries.

As already mentioned, the water jet cutter machine uses water pressure to cut through different types of materials in various shapes and sizes. A water jet cutting machine can be used to cut the following materials:

• Metals: This includes ferrous materials like steel (carbon steel, low alloy steel, stainless steel, etc.), cast iron, and mid ferrous materials. It also includes non-ferrous materials like aluminum, brass, copper, titanium, and zirconium.
• Non-Metals: This includes glass, ceramics, plastic, marble, gemstones, carbon fiber, FRP, etc.
• Composite Materials: This includes water jet cutting for laminate mixes, carbon nanotube materials, etc.

The great thing about all these different types of water jet cutters is that they allow people flexibility and precision, so they can go to town with their cutting needs on any type of material.

Specifications and maintenance of rubber water jet cutting machines

Water jet cutting machines are available in various specifications to meet different industrial cutting needs. Based on the maintenance requirements of these machines, it is essential to understand their cutting capabilities and other parts.

The specification of rubber water jet cutters mainly includes their cutting power, pressure, nozzles, feeding systems, control software, and motion systems.

• Cutting power: Water jet cutters have different power ratings to support various pressure generation. It is usually measured in horsepower (HP). Higher cutting power means more pressure and the ability to cut thicker materials.
• Pressure: The pressure of a water jet cutting machine is measured in pounds per square inch (PSI). It determines its cutting strength. Common pressures are 50,000 psi, 60,000 psi, and 90,000 psi. Higher pressure enables cutting tougher or thicker materials.
• Nozzles: The size and type of nozzle affect the water jet's cutting precision and speed. Different nozzles generate different-sized water streams. This include diamond nozzles, round nozzles, and others.
• Feeding system: It is the mechanism that delivers water and abrasives(for abrasive water jets) into the cutting stream. Some types of feed systems include hopper-fed systems, direct injection systems, or others.
• Control system: Water jet cutting control software is responsible for directing and controlling the machine's cutting path and parameters. Moreover, it sets the water pressure, feed rate, nozzle type, etc. It includes AutoCAD, Water Jet Software, and more.
• Motion system: Water jet cutting machines use motion systems to move the cutting head or workpiece. It includes the belt-driven system, linear motor system, etc.

Regular maintenance helps ensure the water jet's performance, precision, and reliability. The abrasive conveyor part and the cutting head part should be checked and cleaned at least once a week. Replace immediately if there are signs of any parts that need to be lubricated and rubbed out.

Shimming the cutting head nozzles to get the water jet right is part of the week to two-week maintenance schedule. The critical part about this is every time one of the nozzles gets replaced, it should be shimmed. This can then cut overhead costs because there will be minimal downtime as long as the cutting head nozzles are on.

12-24 month maintenance involves calibrating the water jet machine and flushes the high-pressure lines to remove any debris or build-up. The transmission system should also be lubricated, and the drive belts, tension, and alignment should be inspected or replaced when needed. This actually prevents quicker machine wear and tear and is more cost-effective and time-efficient to do.

An annual water jet machine maintenance should also include routine filter replacements, including abrasive cutoff and hopper dust collection filter. The high-pressure water pump's performance should also be tested, and the pump seals should be replaced immediately if required. Besides regularly cleaning the machine as advised, routine inspections should be done to see if parts need to be replaced or repaired.
