CNC-based machining can be described as a broad variety of machining applications. Computer Numerical Controlled is a programable feature that permits the machine to carry out a range of functions without human intervention. CNC machining refers to the process of fabricating an item with a CNC controlled machine. This term refers to the various subtractive manufacturing techniques that require the removal of materials from a bar or workpiece in order to create the final product. Five kinds of CNC machining China that are executed by five distinct types of CNC machines, are commonly used.

This technique is utilized in many industries, including aerospace, medical, industrial, oil & gas, hydraulics and firearms. Many different materials are able to be CNC made into, such as metal as well as plastics, glass composites and wood.

CNC machining has numerous advantages over conventional machining that isn't programmed. Significantly reduced cycle times, improved finishes , and many other features can be performed simultaneously, and improve the quality and reliability of. This is ideal for medium and large volume production where precision and complexity are crucial.

CNC Lathes and Turning Machines

The capability to turn material when machining is the primary feature of CNC lathes and turning machines. The cutting tools used in these machines are fed in a linear motion along the rotating bar stock by removing the material from the entire circumference until the required diameter (and feature) is achieved.

A part of CNC lathes is CNC Swiss lathes (which are the kind of machine Pioneer Service operates). CNC Swiss lathes allow the bar of material to spin and slide axially through the guide bushing that acts as a holding device. This provides much better support for the material as the tooling machines the part has (resulting in better/tighter tolerances).

CNC lathes and turning machines are able to create internal and external components with features like bores, holes broaches, reamed holes, slots, tapping, threads, and tapers. CNC lathes are able to create components such as screws, bolts or shafts.

CNC Milling Machines

CNC milling machines are distinguished by their ability to spin cutting tools while keeping the block or workpiece stationary. There are a number of shapes, including faces milled (shallow flat surfaces, cavities in the workpiece) and peripherally milled (deep cavities such as threads and slots).

Components manufactured on Computer Numerical Control Machining milling machines are typically square or rectangular shapes with a variety of features.

CNC Laser Machines

CNC laser machines have a pointed router that emits a laser beam with high focus. The laser beam can be used to cut, make a cut, or engrave materials. The laser's heat source heats the material and causes it to melt or vaporize, resulting in a cut within the material. The material is typically the form of a sheet. To make a precise cut, the laser beam moves between the sheet and the laser beam.

This method can result in a wider range of designs than conventional cutting machines (lathes or turning centers, mills), and often produce cuts or edges that don't require any additional finishing processes.

Part marking and decoration of machined parts is a typical use of CNC laser engraving machines. For example, it can be difficult to mill a logo and company name into an CNC milled or CNC turned component. Laser engraving can be used for adding information to the piece after the machining processes have been completed.

CNC Electrical Discharge Machines (EDM)

The CNC electric discharge machine (EDM) makes use of controlled electrical sparks to modify materials to a desired shape and is also known as a CNC electric discharge machine. This can also be called spark erosion, spark machining spark sinking, wire burning, or wire burning.

The machine releases an electrical discharge from the wire that generates intense heat. Then, a component is placed underneath the electrode wire. The component is then melts or flushed with liquid to produce the shape you want or design.

EDM can be used to make precisely-sized micro holes, slot angles, tapered or angle features, and other complex features on workpieces or components. It is typically used for extremely hard metals that will be difficult to machine into the desire shape or feature. An excellent example is the gear that is commonly used.

CNC Plasma Cutting Machines

CNC plasma-cutting machines are also used to cut materials. However, they perform this operation using a high-powered plasma (electronically-ionized gas) torch that is controlled by a computer. Plasma torch can reach temperatures as high as 50,000 F, which is similar to the gas-powered torch handheld that is used for welding (up to 10,000 Fahrenheit). The plasma torch melts the material and creates cuts in the material.

To be considered a necessity, any time CNC plasma cutting is employed, the material being cut has to be electrically conductive. The most popular materials include stainless steel, steel, aluminum and brass.

Precision metal casting services provides a wide selection of production capabilities components and finishing during the manufacturing process. There is always an optimal method for achieving the desired results, contingent on the material, environment, budget, time and other elements.
