Plasma Cutter have been around for over 50 years. Plasma Cutter were a major part of World War II era. During the war, there was a demand for a more efficient and speedier way to cut and mold metal for aircraft maintenance and production.
After the war, the plasma cutter process was so effective it was widely accepted by manufacturing and production companies as it considered the best way to cut metal. Fabricators realized the cutting quality and the effectiveness of the cut was a great addition to the manufacturing world.
In recent years with the development of transformer unit and plasma cutter inverter technology, Plasma Cutter have become more affordable and available to small fabrication shops, auto body shops, manufacturing plants, welding professionals, welding hobbyists, and garage shop owners. Longevity has been a leading manufacturer of affordable Plasma Cutting and welding equipment allowing even more individuals the opportunity to use, feel, and own a plasma cutter due to the low cost pricing.
Today, Longevity® produces quality and affordable plasma cutters for all individuals and a must have tool in your plant, shop or garage.
Plasma Cuttingvs OxyFuel (Oxy-Acetylene)
Since plasma cutting is a fairly new technology compared to OxyFuel cutting, there has been a great debate on which process is more affective, which to purchase, and whether upgrading to a plasma cutter is worth the money. To answer some of the debated topics, Longevity will explain
the difference of the two processes and point out some key facts to help you make an informed decision on whether or not a plasma cutter is a good investment for you. There are various factors that you must considering before investing in a tool that will cut metal in guidelines with your needs. Some of these factors are the thickness of the cut, location of work, type of metal, power resources, and operating costs just to name a few.
How does each process work?
Plasma Arc Cutter:
The Plasma Cutter process works when gas (mainly compressed air) blowing through at high rates combined with electricity forming an arc that is extremely hot causing metal to melt away while blowing off the slag.
Are you a homeowner who is looking to start a kitchen remodeling project? If so, are you doing that project by yourself? While a large number of homeowners make the decision to hire a professional contractor, others do not. Not only will you have control over your kitchen remodeling project, but doing your own remodeling may save you money. Although there are a number of benefits to remodeling your own kitchen, there are also a number of disadvantages. One of those disadvantages is the risk of injury.http://www.kitchen.moneybizhome.com
One of the many reasons why kitchen remodeling can be termed dangerous is because of the tools that are used. Whether you are replacing your kitchen lights, your kitchen cabinets, or your kitchen flooring, you will likely need to use a collection of tools; tools that may be unsafe if used improperly. That is why it is important that you know all of the tools that you will be using, including their dangers. Although there is a good chance that you have used a box cutter or a saw before, there is also a chance that you haven’t. Before you start your kitchen remodeling project, it may be a good idea to practice with and familiarize yourself with the tools that you will be using. When it comes time to starting your remodeling, you should know how to safely use all of your tools; thus reducing your risk of injury.
It is also important that you know your own physical limits, when remodeling your kitchen. Whether you are replacing your kitchen floor tiles, installing new kitchen cabinets, or installing a new kitchen countertop, you need to know how much is too much to lift. Lifting too much weight may result in back injury; therefore, if you need assistance from someone, ask for it. It is also advised that you keep your overall ability to work in mind. Even if you are trying to get your kitchen remodeling project finished as soon as possible, it is advised that you do not push yourself. When you are tired and working, your safety is not only at risk, but the overall outcome of your project is also because more mistakes may be made. If you need a break, even for an hour, take one.
When remodeling your kitchen, it is also advised that you keep aware of your surroundings; this includes who else is in the kitchen. If you are remodeling with a friend or a relative, it is a good idea to know where they are at all times. This will help to prevent accidentally injuries. It is also important to keep an eye on who may enter the kitchen when you are remodeling. If you have children, it may be a good idea to block the entranceway to your kitchen. If you are unable to do so, you will always want to know if and when your children enter the remodeling area. If you have young children, it is advised that you never leave your remodeling tools laying around, especially large, sharp tools.
Perhaps, the best thing to keep in mind, when remodeling your kitchen, is to use your common sense. Listening to your head or what your body is telling you, like when it signals that you may need a break, is the best way to stay safe when remodeling your kitchen. It is also, as previously mentioned, the best way to ensure that you produce quality work.

Yoda Force FX Lightsaber
YODA: “Much to learn you still have.”
COUNT DOOKU: “It is obvious this contest will not be decided by our knowledge of the Force, but by our skills with a lightsaber.”
Star Wars, Episode II: Attack of the Clones
Since Yoda was created digitally for the prequel trilogy, his lightsaber was also a digital construct. And so, Lucasfilm once again granted Master Replicas engineers access to the ILM computer files and reference images, allowing for the creation of the most authentic, realistic Force FX lightsaber possible. While the Yoda Force FX Lightsaber is smaller than anything released to date – measuring roughly 33-inches (including the blade), versus average Force FX which measures 44 inches – remember, as Yoda taught us, “Size Matters Not!” http://www.find-me-a-gift.co.uk/yoda-force-fx-lightsaber.html

One of the best ways to save time and money in injection mold making is by using hard milling techniques. In fact, if you are not already hard milling, you will soon find yourself at a distinct competitive disadvantage.
Why use hard milling?
To save time
Reduce set ups
Eliminate a great deal of EDM work
Eliminate hand fitting, especially of contoured shut-off surfaces
Produce a surface that is much more true to the CAD model
Eliminate a great deal of stoning and polishing
Move work through the shop more quickly
Eliminate many grinding steps
Shorten delivery dates
Those are some pretty compelling reasons to use hard milling! After all, who doesn’t want to achieve any or all of the above benefits?
Do you need specialized CNC milling machines?
Yes, and no. No, you don’t have to go out and buy a half million dollar vertical milling machine, in fact, you can do a lot on a basic Bridgeport type of machine. But, if you are serious about hard milling, you should definitely invest in a machine that is designed for this purpose.
You need a CNC milling machine that is rigid enough to withstand the forces generated by the high spindle speeds, rapid feed rates and the vibrations caused during machining. Nowadays there are many high quality machines that are specifically designed for high speed milling and hard milling.
A CNC milling machine used for hard milling should have
A column and base that is heavy
Box ways with linear roller bearings
A spindle that is core cooled
Ball screws that are dual supported
Thermal stability and structural rigidity
Do you need specialized software?
Again, yes and no. No, you don’t need CAD/CAM software that is engineered specifically for hard milling. But your quality will suffer as a consequence.
This is because the requirements for hard milling are different than conventional milling of soft steel. The typical software will cause the cutter to move in a jerky manner, which will shorten tool life dramatically and fail to achieve the desired accuracy and surface finish.
Some other tool path requirements are
The need to control how the cutter enters and exits the cut
The need to maintain a steady, constant chip load
Ensure that the shock conditions for each roughing and finishing pass are maintained
The idea is to produce a surface that is true to the model, dimensionally accurate, has a good surface finish and do it quickly! Sounds like a lot to ask, but it is done everyday by progressive mold making shops around the world. Having the right software is essential.
What about the spindle?
The cutting tool and the tool holder act as one unit. The spindle must be able to protect the integrity of this unit. Therefore, it must be designed for the high speeds that are necessary. Direct drive spindles are called for in hard milling applications. Gear and belt driven spindles are not advised. The control of heat and vibration is also extremely important.
The importance of the spindle cannot be overlooked because it is the link between the machine tool and the cutter. If the spindle is inadequate, the entire process will suffer greatly.
Shrink fit tool holders and an HSK interface are mandatory for hard milling. Sure, you can use other methods, but this combination has proven to be very effective. These tool holders are the most accurate available today and they are very easy to use.
The HSK interface is simply the most accurate, secure and stiff type in use today. Failing to use the proper tool holders will shorten tool life dramatically because the chip load will fall on on flute and quickly cause premature wear.
Conclusion
The hard milling of plastic injection molds is becoming a standard method of mold making. There are so many benefits associated that shops who are slow to get onboard will soon be at a serious loss to compete.
With today’s sophisticated CNC milling machines, coated carbide end mills, ceramic inserts, advanced software and reasonable prices, hard milling is within the reach of almost any competitive mold shop.
