Several Machines Being Used During CNC Machining Process

Computer Numerical Control Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools. Tools that can be controlled in this manner include lathes, mills, routers and grinders.

The idea of numerical control started when the automation of machine tools originally incorporated specific concepts of programmable logic. In the beginning, the first CNC machines were built back in the 1940s. Slightly more advanced machines came along in the 1950s.

CNC now is the leading machine in the world of manufacturing and the answer is very simple because of the high accuracy can reach 0.00005 which is an amazing number, very fast in manufacture also the running software is very simple.

The good thing in CNC machines that it has the ability of custom fabrication services as on machine can make many different parts by changing the program and the tools.

Examples of CNC machines:

  1. CNC Mills:Translate programs consisting of specific numbers and letters to move the spindle to various locations and depths. Many use G-codes Functions include: face milling, tapping, shoulder milling, drilling and turning. Nowadays, CNC mills can have 3 to 6 axes. Most CNC Mills require placing your workpiece on or in them and must be at least as big as your workpiece, but new 3 axis milling machines are being manufactured which you can put on your workpiece.
  2. CNC Lathes: Cut workpieces while parts are rotated. Generally using indexable drills and tools to make fast, precision cuts. It is effective for complicated programs designed to make parts that would be infeasible to make same on manual lathes. Similar control specifications to CNC mills and can often read G-code. Generally, CNC Lathes have two axes (X and Z), but newer models have more axes, allowing for more advanced work to be machined.
  3. Plasma cutters: Involves cutting a material using a plasma torch. Commonly used to cut metal such as steel and other variety of materials. In this process, gas is blown at high speed out of a nozzle; at the same time, an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is enough hot to melt the material being cut and moves fast to blow molten metal away from the cut.
  4. Electric discharge machining: (EDM), also known as spark machining, spark eroding, burning, die sinking, or wire erosion, is a manufacturing process in which a desired shape is machined using electrical discharges (also called sparks). By a series of rapidly recurring current discharges between two electrodes, the material will be removed from the workpiece. That is separated by a dielectric fluid and subject to an electric voltage. One of the electrodes is called the tool electrode.The other is called the workpiece electrode, or “workpiece.”
  5. Wire EDM: Also called wire cutting EDM, wire burning EDM, or traveling wire EDM. This process uses spark erosion with traveling wire electrode to remove material from any electrically conductive material. Wire electrode usually consists of brass or zinc-coated brass material. Wire EDM allows for near 90 degree corners and applies little pressure on the material. Since the wire is eroded in this process, wire EDM machine would feed fresh wire while chopping up the used wire.
  6. Sinker EDM: Also called cavity type EDM or volume EDM, sinker EDM which consists of an electrode and workpiece submerged in dielectric fluid. A suitable power supply would connect the electrode and workpiece, generating an electrical potential between the two parts. As the electrode approaches the workpiece, dielectric breakdown occurs in the fluid forming a plasma channel and small spark jumps. Casting dies and molds are often made with sinker EDM. Some materials, such as soft ferrite materials and epoxy-rich bonded magnetic materials are not compatible with sinker EDM because they are not electrically conductive.
  7. Multi Spindle Machines: It is a type of screw machines which are usually used in mass production. Normally,considered to be highly efficient by increasing productivity through automation. Would efficiently cut varies of materials into small pieces while simultaneously utilizing a diversified set of tooling. Multi-spindle machines have multiple spindles on a drum that rotates on a vertical or horizontal axis. The drum contains a drill head which consists of a number of spindles that are mounted on ball bearings and driven by gears. Two types of attachments for these drill heads are fixed or adjustable, depending on whether the center distance of the drilling spindle needs to be varied.
  8. Waterjet Cutter: It is also known as a waterjet, is a tool capable of slicing into metal or other materials by using a jet of water at high velocity and pressure, or a mixture of water and an abrasive substance, such as sand. It is often used during fabrication or production of parts for machinery and other devices. Waterjet is the first considered method when the materials cutting is sensitive to the high temperature by other methods. It has found applications in a variety of industries from mining to aerospace where it is used for cutting, shaping, carving, and reaming.

There are some of CNC machines we didn’t mention it.

The world is running fast in the field of innovations and every day we have a new thing that keep the people away from the dangerous work and increase our ability to manufacture more accurate machines and parts as it’s used now in many fields as : ( diesel manufacturing – aerospace parts machining – also in ship parts production)
