How the Waterjet Cutting Process Is Helping Surgeons of Today?

There are projections that we are on the verge of replacing the traditional stainless-steel scalpel of a surgeon with a cutting device that will make use of high-pressure liquid. This is the consensus and observation of various insiders in the medical and surgical industry following the celebrated testing and patenting of prototype equipment of this type which was held in Germany.

Engineer Andreas Pein of Euromed Medizintechnik in Schwerin, Germany spearheaded the overall design of the system. It is making use of a pump to help in forcing sterile water-based cutting through extremely tiny nozzles. Water pressure is made to reach a minimum of 150 bar. With this amount of pressure, the waterjet cutting process is made strong enough for it to be able to slice through the kidneys, hearts, and livers with very minimal damage to the surrounding blood vessels, nerves, and bile ducts.

The primary goal of this particular engineer from Schwerin, Germany was to come up with a viable human organ cutting technique that will leave the least amount of damage to the healthy tissue being worked on. The overall design of this device was inspired by the technology utilized by the manufacturing and metal fabricating industries when they are processing fiber-reinforced composites and cutting steel.

The device comes with several special adaptation features. This would include the foot-pedal control that will help enable a surgeon to have variations on the pressure of the jet while carrying out surgical operation procedures. It also provides a means to effectively control the temperature of the liquid in the device. The liquid, in the latest prototype, can be heated for up to 80 degrees Celsius. This temperature range of water is most helpful in reducing bleeding during the operation.

This system is more advantageous over laser scalpels in the sense that it offers the freedom to change the pressure during the cutting procedure, allowing surgeons to enjoy a certain degree of liberty in being selective. Like for instance, it allows the cutting of a liver tissue sans causing damage or cutting a vein.

Another remarkable thing happening at the Euromed engineers at the moment is that they are 

keen on finding possible ways to supercool a liquid and make use of that technology to cause the jets of water to emerge not as a liquid but in the form of ice crystals instead.

If they find success in this aspect anytime soon, it will make it possible for them to cut through bone structures and other similar hard tissues without any difficulty. In addition, it will be most suitable for use in surgeries that are intending to replace joints. 

There is also a good possibility that the waterjet cutting process can be coupled with a surgical laser. Laser technology has been tapped into for application in a wide spectrum of surgical techniques. This would be ranging from hernia operations to removal of cataract in the eye, but the optical fibre responsible for bringing the beam of laser to the tissue to be cut off has a tendency to overheat, and thus need to get replaced.

These Euromed engineers are making good plans for replacing the optical fibre or its last few millimeters with a low-pressure water jet. The fiber that is tasked with carrying the laser will eventually end up in a liquid-filled pressure chamber. By this measure, the laser light will be conducted via the water jet, keeping the optical fibre and the tissue from being heated up.

What Do You Know About the CNC Plasmacam Router Machines?

It takes more than just a very keen eye to see the application of CNC plasmacam router machines in many industries today. Major industry players from small scale companies to the big players in the business, they all have it. To be honest, there is hardly any part of the manufacturing sphere that does not need the benefits of automated machining that is taking advantage of CNC technology.  

If anyone wishes to get involved with the manufacturing industry, he must understand how important the role of CNC plasma kits Australia in advancing a business organization’s market interest.

Should you contemplate obtaining a piece of metal-cutting equipment like a plasmacam tool, then it comes to follow that you commit to learning a great deal about it first. This way you will save yourself from making wrong decisions that you will later regret. It is also a good measure to give yourself the right expectations.  

System Cost 

This aspect has something to do with the expenditures involved in software acquisition, accessories, construction, and installation. A plasmacam is ready to use the material cutting system, it can readily cut off required parts for your upcoming projects. But before you can have it running smoothly, a computer system and a handheld plasma torch should be available already on-hand. Aside from those 2, there is nothing more that you will need to buy or build. 

Operating Cost

CNC cutting systems are highly reputed due to their ease of use and offered convenience to users. Aspects that deal with training, operating, maintenance, operating costs, and time are all minimal. There is another good thing about it that is worth celebrating, it actually takes away or puts aside the need for knowledge or expertise in computer programming.

The Handheld Plasma Torch

These tools make use of a handheld plasma torch. It allows for offering and delivering excellent performance and the best flexibility ever from the equipment. Plasma torch machines are considered by many as having a bit expensive price tag, although it does not bring you any performance advantage to brag about, unlike the handheld torch. 

Some of the plasma torches available in the market today don’t have any provision for you to install a machine torch. But when you know how to take advantage of this system, you are up for a good amount of savings for your company. There will be instances also that you’d be able to utilize this material cutting system for those projects that necessitate the use of hand cutting work. 

Control systems are utilizing open-loop feedback which means that the load fluctuations cause its motors to skimp on some necessary steps brought about by the controller and have lost its position.  

The controllers provide an accurate report about the machine and its position back to the controller. The servo controller is working behind this using closed-type loop feedback. This allows for the perfect maintenance of this position despite varying conditions.

Advantages of Working with Water Jet Cutting Machine

The engineering and the manufacturing sphere has always been engaged in a battle to reduce costs, hence, these industries are always on the lookout for an edge for this purpose. The technology running behind the waterjet cutting machine provides a variety of capabilities and advantages that will prove as substantial in the war to lower costs. 

Learning more about waterjet cutters and how this technology works will allow us to put their cost-cutting capabilities to our advantage. Beyond its substantial contribution to any cost-cutting measures, the process behind the waterjet cutter is recognized as versatile as versatile can be.

Besides that point, it is also considered among the fastest growing and widely used material cutting processes in the globe. It is because it is taken advantage of in various high production applications, and the material cutting results are always at par with expectations. 

Extremely fast water jet cutting machines complement other material cutting technologies we have today including the laser, plasma, EDM, milling, and router cutters. It will not produce nor need noxious gases or liquids. There are no heat-affected zones and will not leave out any traces of mechanical stresses on your waterjet cut surface. It truly is a qualified productive and versatile, cold cutting process. 

Advantages of abrasive and waterjet cutting: 

  • Increased cutting speed
  • Decreased wear on pumps and nozzles
  • Narrower kerf cutting width
  • Improved surface finish
  • Decreased abrasive use
  • Diminished tendency for a jet to wet substrates
  • Decreased taper

The Waterjet Cutting Machine Process

The original method employed by the waterjet machine is just pure waterjet, with no abrasives included. Nothing of that kind. This will utilize the pressurized stream of water in cutting through a material. 

Pure, non-abrasive water jet cutting is limited only to materials that come with inherent small cracks in them or softer materials like tissue paper, disposable diapers, and automotive interiors. 

This process involves increasing the water pressure by virtue of a high-pressure pump to around 40,000-60,000 PSI. This high-pressure water will force its way via an orifice towards the target material.

Upon striking the surface, the high-pressure water will carry out the machining operation, converting the potential energy residing in the water into kinetic energy thus rendering it possible to achieve the expected “cutting” effect.  

The basic process of a waterjet will involve water going from a pump, then will go through plumbing, and then heading out the cutting head. 

The material removal process in waterjet cutting can be best described as one supersonic erosion process. Pressure has got nothing to do with it, but the stream velocity will significantly help in tearing away grains or the microscopic pieces of the material. 

Pressure and velocity. Both of them are distinct energy forms. The water pressure in the pump will be converted to another energy form, water velocity by virtue of a tiny jewel, with a tiny hole. 

The pressurized water will pass that miniscule opening, transforming the pressure into velocity. At around 40,000 psi, the resulting stream will pass through the orifice.

Your Guide to a Successful GPS Antenna Installation

We have a handful of simple guiding rules when it comes to having external GPS antennas that come with their in-dash navigation receivers. The first cardinal rule we have to remember here is not to cut or modify your antenna in any way. The second one is to make sure that it is consistently having contact with those GPS satellites that are orbiting the earth.

This explains the reason why you need to mount your antenna to, say your car, in such a way that it would minimize the likelihood for interference to occur. 

Most of the time, GPS antennas can be mounted on your dash, near the top of its underside, just above or behind the receiver. Nowadays, we have strong and reliable satellite signals which makes it all-sufficient when it comes to maintaining your required reliable reception. It also allows you to keep your antenna hidden, and thus would be out of sight.  

reliable car GPS

Alternatively, some of the leading brands you will find in the market today would recommend mounting their offered GPS type of antenna either along the rear deck or on the dash. If you do so,  make sure that it will have open access to a clear, cloud-free sky. Also, see to it that it is not very much in close range to a 2-way antenna or A-pillars — it should work okay that way. 

Do you want to know under which cases you can install your antenna on your car exterior? 

Check out the following scenarios for this: 

  • you have metallic window tint
  • you wired rear defroster
  • Your car window is solar reflective
  • you radio antenna is a windshield-mounted type

It is also paramount that a GPS type of antenna is as level as possible. This will allow it to have a solid connection to its attached metal sheet or plate, in the absence of one. Some kind of adhesive will keep the antenna to remain in place. 

After this, you have to route your antenna wire to the receiver’s rear along the floorboard or dashboard. You can also course it through a door or window seal.

Wire connections

Receivers that are equipped with video screen features need to have several wire connections that are not at all necessary in non-touch screen stereos.  Here is a closer look at some of them. 

Parking brake wire connection

If you have equipped your vehicle with whatever kind of video screen application, for safety reasons, you must see to it that it is also attached to the parking brake wire. This measure is also applicable to your vehicle’s GPS  antenna systems.

While your car is in motion, the advanced navigation functionalities it came with will be disabled.  If you need to look for a particular phone number, or if you want to change something at the unit’s default settings, what you need to do is to pull over the vehicle first. It seldom happens though that the use of a foot brake would also be necessary.  

Reverse signal wire connection

Navigation systems also need to access your car’s back-up light or reverse signal wire.  This connection will indicate to the vehicle navigation system that your car is traveling in reverse.  If this wire is not connected or not hooked up, then your vehicle will have a hard time tracking properly. It will render your navigation system to fail on its job and designed purpose.  

Help on Choosing and Installing Navigation Receiver

You only need to follow several extra steps when installing a navigation stereo, the in-dash type.  If you are about and all set to shop for your next navigation receiver, it is important to know and identify first what models are likely going to work and are compatible with your car.
