The CINC machining process is not monotonous as different operations depend on the requirements. In some cases, the desired shape can be obtained by a single operation such as milling. However, this only works for very simple designs. In general, the more complex the design, the greater the variety of operations required. Below are some of the main CNC machining operations common across the industry
CNC milling machine
CNC milling machines operate on a vertical axis and use rotating cutting tools to create different shapes or products. This process is prevalent in several industries including automotive, aerospace, medical devices, and their consumer products.
One thing that makes CNC milling different is the workpiece placement. Usually, the workpiece remains stationary while the milling tool moves in a different direction. The cutting tool moves according to the computer program and Remove material. Cutting tools can be rotated at high speeds to create precise cuts and shapes, and the machine can be programmed to make multiple passes to achieve the desired end product.
CNC turning
CNC turning is another indispensable operation that creates cylindrical parts with high precision and precision. The Turing process itself is simple, mount the cylindrical part on the machine, and the machine will
Rotate, the tool will be along the vertical and rotational axis.
CNC turning is a common process for the production of different components, including engine components, shafts, bushings and gears, and offers several advantages over traditional manual turning, including greater consistency Repeatability and efficiency.
There are many types of CNC lathes, including lathes, turning centers, and Swiss-type lathes. The choice of machine tool and cutting tool will depend on the specific requirements of the workpiece and the desired end product.
CNC drilling
Drilling is an important manufacturing process that creates holes of various sizes in a workpiece. The process is fully automated thanks to a computer precisely controlling the movement and speed of the drill.
CNC drilling is very common in many industries including printed circuit boards, metal parts and plastics. This process offers several advantages over traditional manual drilling, including greater accuracy, repeatability and efficiency.
CNC Routing
The rough operation of a CNC router is the same as a milling machine. Routers are typically used for softer materials like wood, while millers are typically used for harder metals. Just like any CNC operation, routers provide excellent consistency, efficiency and accuracy.
During the routing process, the workpiece remains completely still while the spindle moves in different directions. Since the milling process is performed on softer materials, the overall spindle speed may be low. There are many types of CNC mills, including benchtop mills, portal mills, and mobile portal mills. The choice of machine tool and cutting tool will depend on the specific requirements of the workpiece and the desired end product.
EDM
An electrical discharge machine (EDM) is a manufacturing process that uses electrical discharges to erode material and create complex shapes and geometries. The process works by creating a spark between an electrode and the workpiece. The machinist immerses the workpiece in a dielectric fluid, which isolates the electrical energy and allows precise control of the spark. The spark discharge vaporizes the workpiece and removes via material to achieve the desired shape.
There are two main types of EDM: electric discharge machine and wire electric discharge machine. Sinker EDM uses a consumable electrode to create the spark. In contrast, wire EDM uses thin wires that move back and forth to create sparks.
CNC plasma cutting
Plasma cutting is a manufacturing process that uses a high velocity stream of ionized gas (plasma) to cut conductive materials such as metals. In plasma cutting, a plasma torch creates a plasma arc between the electrode and the workpiece, which is powerful enough to cut the material.
In the next step, the plasma arc melts and evaporates the material. The process also requires a high-pressure gas stream, such as air or nitrogen, to blow the molten material away from the cutting edge. This results in a clean, precise cut with minimal warping or discoloration. Therefore, the requirement for any post-processing is minimized.
CNC laser cutting
This is another popular common procedure because of its ability to provide precise and accurate results in the shortest possible time. The laser used for this process is capable of cutting most materials in the industry, which is one of the reasons it is common in most industries.
Another reason CNC laser cutting is so popular is its repeatability. This process is ideal for large volumes of material and repeatedly provides the most accurate results.
Additionally, laser cutting is a very precise process that minimizes waste. This makes it ideal for high-value materials commonly found in the aerospace and automotive industries.
