CNC plastic machining is one of the most popular options for manufacturing various plastic products today. Unlike the traditional methods of production, this method requires less manual intervention and gives better output in lesser time. Similarly, plastic injection molding is used hugely for cheap and durable construction of many consumer and industrial plastic items. Know the various application areas of plastics today.

CNC plastic machining products in Aerospace and Defense:

Plastics have replaced metals in many areas in the Aerospace and Defense industries. This is due to their durability and high performance factor, in spite of being lightweight and also cheaper options compared to their metal counterparts.  CNC plastic machining products are used in the manufacturing process of missiles, rockets, aircraft, satellites, and the space shuttle. Due to their sensitive area of use, all manufacturers dealing with the manufacture of plastic injection molding always go for careful selection, and tested products. Apart from being durable, lightweight and cheaper options, plastic is used in this sector from their chemical and corrosion resistance. Further, they are also radiation resistant and have excellent radar absorption capabilities. Hence, they are far more beneficial than alloys and non-ferrous metals for these two areas of industrial application.

CNC plastic machining products in Medical and Pharmaceutical:

Both CNC plastic machining products and injection molded plastics are used widely in the medical and pharmaceutical industries. This is simply due to the fact that apart from being durable, plastics are comparatively cleaner, which is necessary in these industries.  The plastics manufactured thus use absolutely no petroleum-based coolants in the machines. Moreover, all manufacturers providing plastic needs to these industries should keep in mind that there should be no metallic cross-contamination as they deal with sensitive health issues. Even while going for the cheaper plastic injection molding, manufacturers as well as distributors and vendors should keep this thing in mind. Among the various areas where you would find these plastics are in X-ray, CT scan, and MRI, or open surgical equipment/ machines.

CNC plastic machining products in Down Hole Applications:

The CNC plastic machining products are widely used in Down Hole Applications, where the machines need to be strong enough to withstand high-pressures, high temperatures, and hostile media. Most of the manufacturers offering plastic injection molding products for hole and sub-sea environments would ask you to opt for this as they are better than metal parts. Apart from being long lasting they also offer maintenance-free performance for greater user friendliness.

Whatever your area of operation, go for CNC plastic machining products and you would never ever consider other options ever.

Your first step should be to design the right machine based totally on your wants. The material that you are going to need will rely upon whether you wish to make a CNC router or CNC engraver or any other CNC machine at home. While the majority of the mechanical parts including spindles, chucks, or material for the table should be available at any hardware store ; the CNC controller can also be extracted from old printers. You can even find stepper motors or servo motors easily from various stores.

If you’re uncertain about how to design your homemade CNC machine then you may even use a web search site to locate websites that have fans willing to supply valuable pointers and advice, including blogs, forums and videos on how to design and make your own homemade CNC machine.
Uses of a homemade CNC machine

If you have designed and made a CNC engraver in your garage then you can engrave unlimited designs based mostly on your inventiveness. You may use thin sheets of steel or aluminum to engrave designs and words by using the right software so as to make items such as nameplates and key chains among other items for your family and friends and you. If you have made a router then you might work on wood to make artistic tabletops, legs, photo frames, and so on. If you made a multi-axis machine then you might design and make complex parts for varied machines or even make hard-to-find tiny parts for antique cars as per orders that you receive from various auto repair workshops.

It is really important that you have some concept on how to handle tools like drilling machines and computers and have sufficient knowledge about electronic circuits before you even think about making your own machine at home. If at all possible, get help from a guru so as to get it right the first time itself. You’ll also need to figure out the scale of the table or bed and the power required for your motors before you start to make your machine. Safety should be of supreme significance in a homemade CNC machine and an emergency bypass switch should be included in your CNC machine. Don’t forget to wear safety equipment like spectacles or gloves whilst using your machine. If you are mechanically and electronically inclined, then making a homemade CNC machine could be a superb project that would help you to create objects using your imagination. You may also turn your creative spare time pursuit into a well-paying business. You can certainly make your own CNC machine with assistance from the right design, top of the range parts and maybe even one or two friends.

Anyone connected to EDM machining is all too familiar with the scene. The scenario goes something like this:

You spend hours designing an injection mold core or cavity, days CNC milling and grinding to get the size and shape required. The only thing remaining is the EDM machining of the details. You have the graphite electrodes made up,which takes a couple more days, and finally everything is set up in your CNC EDM machine.

Typically, you might make 4 cavities, which will produce 4 exactly identical plastics parts when everything is finally finished. Thing are going well, you have run the first 6 different shaped electrodes through the process, now there is just one more. Only another 16 hours and you will be done and onto the next project.

So, you get it all set up to run all night, and you feel confident that everything is as it should be, you can sleep peacefully without waking up in a start, wondering if you did this or that before going home.

You come in the next day

You check on you job the next morning and inspect it while still in the machine, it all checks out, so you remove it, clean it up and give it to the mold polisher to make it all shiny and nice. Soon, he comes in and tells you he needs to show you something. Oh oh…

Sure enough, right at the bottom of the deepest part, a rib that is there to make the plastic part stronger, is a pit. Another name for this pit is a DC arc, or zit, or some expletive that is unprintable. What this means is that there is a small hole, or crater at the most inaccessible region of your mold that looks like it was bombed when you view it through a microscope.

Now you need to get creative and fix it, if you can. Usually there is some convoluted way to fix it by cutting out the bad part and making an insert to replace the pitted area. Sometimes though, it is just not possible to repair it and the entire piece must be scrapped!

How to prevent EDM pitting

DC arcs are primarily caused by one thing: bad flushing. Even with central flushing or lateral flushing, there can be dead spots where EDM sludge builds up; the bottom of ribs are a favorite hiding spot.

The sludge acts like part of the electrode and attracts sparks that arc across the dielectric fluid and faithfully reproduce their shape in the steel. If this continues for a length of time, you get a pit. The longer it persists, the bigger the pit.

Dirty oil is also a common culprit to DC arcing. This happens because the filters are full, or not fine enough to filter out the EDM sludge and grit. It should be able to filter down to a 1 micron size in order to ensure no pitting due to dirty oil.

Some manufacturers claim that their machines have software that prevents DC arcing, and to a great extent they do. Mostly this is by retracting the electrode out of the cut so flushing can occur. Some have a high speed oscillating effect that improves the flushing as well. Then there are some that have improved cutting parameters that will adapt when the machine senses a DC arc.

All of these methods really get down to improving flushing. Even high tech, new EDM machines will pit. I know because I have had to polish many surfaces EDM’d by these machines! You will find a nice looking surface that is not so easy to detect until you begin removing the first layer of recast.

Then you will find many, pits, not big enough to scrap the part, but certainly big enough to make the polishers job much more difficult and possibly changing the dimensional integrity of the steel.

Save yourself time and money

It might seem like a waste of time to make sure you have adequate flushing, but in the long run, it will save you time and money. Even with the high end, new EDM machines, you should keep this in mind. Whether you deal with it through the circuitry or mechanics of the orbiting or the filter, make sure you take care of the flushing

Electrical discharge machining is an amazing machine tool with tremendous importance for manufacturing. It is possibly the least known and most used machine for producing the endless variety of plastic products we use and appreciate everyday. Just look around you!
