The technology behind CNC has been evolving over years since the 1940S. A lot of improvements have been made to suit the needs of the consumers. The plasma cutting machines are now suitable for large and small-scale manufacture, artist and even DIY enthusiasts. Easy to cut  precious metals to any shapes. The machine has made it easy to cut precious metals to any shapes, it is suitable for the designers who need to customize metal plates, through this wonderful invention industrial business operators can now get quick and accurately cut hundreds of identical shapes using handheld plasma cutting system or mechanized plasma. There are several reasons why plasma cutting machines are very important in the designing industry. The industries have been relying on the heavy metals to build structures, cars, and other components that need accuracy in designing and accuracy from metal components, also its used on medium and lite metal to build home internal and garden decorations. However, while metal is incredibly strong, it’s also highly resistant to damage, meaning specialist machinery is required to accurately cut and manipulate the materials. Plasma and superheated, ionized gas. The plasma cutting technology involves creating an electrical channel of superheated, ionized gas for example plasma from itself through the work peace to be designed, thus forming a completed electric circuit back to the plasma cutter via a grounding clamp. This is normally accomplished by compressed air, Oxygen and other inserts depending on the material being designed. The process formed an arc within the gas between an electrode near or integrated into the gas nozzle and the workpiece itself. The arc ionizes some of the gas this creates an electrically conductive channel of plasma. As this electricity being formed, the cutter torch travels down the plasma which it delivers sufficient heat to melt through the workpiece. At the same time, the compressed gas together with high-velocity plasma blows the hot molten metal away this help in separating the pieces. Thickness and limits. You get a perfect cutting on both thick and thin materials alike using plasma as a cutting tool the normal hand cutting can be used to cut up to 1.5 inches (38mm) thick steel plate. A stronger computer controlled can cut up to 6 inches (150 mm) they are extremely useful for cutting sheet metal in curved or angled shapes this is because the plasma cutters produce very hot and localized cone. Need safety with plasma. The safety measures have to be taken while using any machine in the world, and it is recommended to use the guidelines put in place by inventors and manufactures regulations in order to be safe when using them. Proper eye protection and the face shield is required to prevent arc eye and debris damage. The recommended lenses to use are green lenses shade. All Entire DXF Files Packages (Bundle) only $1599.99

   When looking at purchasing a CNC (Computer Numeric Control) plasma table, the endless possibilities can make purchasing one difficult. However, knowing what you are looking at and knowing what you will be using your new machine for, will make purchasing one much easier. In this article, we will discuss what to look for in any CNC plasma cutting package. This includes the components, type of table, and supporting programs. Table Components.    The primary components of most tables include the Y-beam, gantry, X-carriage, Z-head, and slats . The Y-beam is the long axis or Y axis that holds the gantry. This allows the gantry to move up and down in the Y-direction.  The gantry rides the Y-beam and holds the X-carriage. The X-carriage or torch carriage holds the torch assembly and allows the torch to move up and down the X-axis. The Z-head holds the torch and allows movement up and down the Z-axis. On most machines, the X, Y, and Z-axis are controlled by servo motors which allow the torch to move to its desired path. The servo motors and Computer work in conjunction and are what control the movement of the cut once programmed. The slats are metal runners that are spaced across the table. These slats provide support to the part as its being cut. Almost all tables are configured in this setup and are proven to be the most reliable configurations. Some tables come with different features. One feature most tables will come with is a magnetic breakaway torch carriage. This can save you time and money. If programmed improperly a torch can take a nose dive and can cause damage to the components inside or even the carriage. In addition, if a slug lifts up from a part while cutting and a torch makes contact, it can cause damage to the system. With the magnetic breakaway, any force over that of the magnetic force will dislodge the carriage and stop the program. Another key feature is automatic torch control. If a raw sheet is not perfectly flat, a sensor mounted on the carriage can adjust the torch height so you always have proper torch height and do not make contact with the part, which could cause damage. When having both features, programming time will decrease and unintended torch collisions can be less catastrophic. Even though many tables will have a similar setup, the table itself can be vastly different. The reasoning for this is fume control. Types of Tables.    When cutting through the material, extremely hot molten metal is being blasted out the back of the piece scattering debris everywhere.  It is also known that hot air rises and these tiny particles can rise into the air causing inadequate working conditions. Over time with no fume control, an entire shop or garage can become fully covered in black debris. This is where the molten material has landed and stayed. This is not the desired outcome for any hobbyist or manufacturer. To combat this, table manufacturers have come up with two types of tables. The two types of available tables are the downdraft table and the water table . The downdraft table uses a fume extracting system that sits above the table. With the part sitting on the slats of the table, the system then sucks up any debris trying to escape the table while cutting. The water table accomplishes the same goal as the downdraft table but uses water instead of an extracting system. The table works by filling it up with water until the water is close to or touching the desired part to be cut. When the part is being cut the molten material is blasted out the back and hits the water. This instantly cools the molten material and sinks it to the bottom of the table. Thus, by sinking the debris it can’t escape into the air. Both tables achieve the same goal but the water table holds advantages over the downdraft table. When cutting, your part is constantly increasing in temperature. When performing long heavy cuts the heat builds up in the part causing it to warp and bend. This can cause improper torch height and line of cut. This can leave your part with inadequate finished edges or even a bad part. Owners of a water table can fill it up so the water is touching the part or even submerged. This ensures a cool part when performing long cuts. Knowing what type of material you will be cutting or in what setting will determine what table is best for you. Another factor that you will have to consider is what size table you will need. Tables come in all configurations. Most table manufactures provide a set list to choose from. However, some table manufactures allow for custom sizes. The reasoning for this is due to the simplicity of the parts and function as explained above. Software.   When purchasing a package, many manufacturers will have proprietary programs that will come with the package that allow operation of their product. This is commonly called ...

   When programming a CNC (computer numeric control) cutting machine, there are many factors that affect how the machine cuts and the quality of the finished part. In this article, you will learn how to program properly by understanding programming techniques and conditions. This includes understanding your machines supporting slats, programming strategic tabs, and pierce/lead in conditions. Support Slats.    When programming there are many factors and obstacles to consider. If not programmed correctly or obstacles not accounted for, you not only will make bad parts but also will damage your machine. A single mistake can cause a whole sheet to be scraped or your machine to be repaired. When programming a single part on a sheet, you must first think where on your sheet you will burn the part. On most machines, there are slats that span the table. These slats are used to hold the sheet up and allows the cutting source to pierce through the material and disperses off around the slat or in the gap of the slats. Slats will need to be replaced because slag will build upon them from heavy use or cutting that occurs in the same area. So, when picking where on the sheet you will burn the part, you will need to consider where the slats are and how far apart they span from one another. The reasoning is because of tipping. If the part is big there is no reason to worry about the position. The reason is that the part will be properly supported all around from the slats. However, if the parts are small your raw sheet is supported, but once the small part is cut out it may fall through. Not only may it fall through but it could tip up and when your cutting head moves past, it can collide and cause massive damage. To avoid this, you can cut the part out on a position or orientation that properly supports the part on one or preferably two slats or use tabs. Tabbing.    Tabs, also called micro joints are used to secure the part to the sheet via small fingers of metal. You can achieve this in two ways. As you cut around the perimeter of the part you can stop the cut whatever distance early to allow a solid tab to be left. For example, if I cut a one-inch hole out of 0.125” steel, I would program the part to stop about 0.020” short of completing the one-inch hole. This allows 0.020” of material to hold up that one-inch hole. This is plenty enough to hold up the weight. However, if the feature cut out gets bigger or heavier due to size or material thickness, the tab will need to be thicker to support the added weight. Be sure to tab accordingly. If the tab is too skinny the part will break out due to the assisted air of the cutting machine. If too heavy you won’t be able to break the part out. The other way to create a tab is a reentry. This occurs when you're cutting and you stop the cut slide over the desired tab distances and continue the cut. This is the least desirable way to create a tab because it requires another pierce because your picking up and moving down which requires a pierce to begin cutting again. However, when burring out parts most times you will have to put two tabs on the parts, so it doesn’t tip. Thus, you utilize both tactics to achieve proper support of the part. Tabs sound like a nice way to always keep a part secure. However, over tabbing has its drawbacks and should only be used if needed. The reasoning is due to dross and tab residue. When you finished burning a part with tabs you must then break it free. This is why you do not want to make the tab too thick or you will have to use a hammer to break them out. When you break it out a bit of the tab will be left over on the raw sheet and the part. When you run your finger down the edge of the part there will be a bump where the tab is. You will need to file it off or grind it off along with the dross. When running heavy small parts thick tabs will be needed. Thus, you most likely will be grinding, and no one enjoys grinding. To combat this, you can use proper part placement and skip the tabs or use strategic tabs and keep the number of tabs down or their thickness. A trick to have clean finished parts is to over tab if the part can safely rest on the slats when cutting out. An over tab is when you program your cut to continue to cut past its final destination by a few thousandths of an inch. This guarantees the part is fully cut away from the raw sheet and takes off any burr that would be left from the lead in. Piercing and Lead-Ins.    When cutting out a part you must first program a pierce and lead in. The pierce penetrates the raw sheet, that then allows the beam to start cutting on its desired path. The piercing is a higher intensity that is trying to penetrate the metal. This requires changing conditions as the sheet gets thinner and thinner. This will cause a bigger hole than the actual cutting beam width. Additionally, from the pierce, molten material will splatter and cause dross. Because of...
