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.
