CNC Machine, its full name is Computerized Numerical Control Machine. It’s a computer numerical control machine tool. People also call it a machining center or computer gong. It can process different materials like metals, plastics, wood, glass, and composite materials,It does this through ways like cutting, milling, drilling, and grinding.
Processing method
CNC milling machine: It’s mainly for milling, It can process parts of all shapes and sizes. Usually, it has a multi – axis control system.
CNC turning machine: It’s mainly for processing rotating CNC machining parts,It can do various internal and external cylindrical surfaces, conical surfaces, and spherical surfaces efficiently.
CNC drilling machine: It’s mainly for hole – making by drilling, It’s a high – precision and high – efficiency drilling tool.
CNC wire cutting: It cuts materials by the discharge principle, It’s good for hard materials like cemented carbide and hardened steel.
CNC laser cutting: It cuts with a laser beam, It’s suitable for normal materials like aluminum alloy and stainless steel.
CNC grinder: It’s mainly for grinding, It removes materials with grinding wheels to get the right surface roughness and precision.
CNC boring machine: It’s mainly for vertical boring and drilling, It’s good for big and heavy workpieces.
CNC electric spark (EDM): It uses the electric spark discharge principle to remove materials, It’s good for complex and tiny parts that are hard to process with normal cutting.
CNC water jet cutting machine: It uses a high – pressure water jet or a mix of water and abrasive to cut materials, It’s especially good for materials with low thermal resistance.
When we talk about CNC machining service , we usually mention the above processing methods. These can also be seen as types of CNC machining manufacturing Tools.
Working principle
Input: The operator writes the geometric and process information of the cnc custom parts to be processed into a CNC program with a special programming language. Then, the operator puts this program into the control system of the CNC machine tool. This information includes the part’s shape, size, processing path, and cutting parameters.
Processing: The control system decodes, calculates, and does logical processing on the input program. It changes the program into motion instructions and other control signals for each coordinate axis of the machine tool. This controls the machine tool’s movement.
Drive: The signal from the control system makes each coordinate axis of the machine tool move through the drive device, like the servo motor driver. So, the tool and the workpiece move relative to each other as planned, and the part processing is done.
Components
Control system: It’s the heart of CNC manufacturing, It’s like a human brain. It tells and coordinates the work of different parts of the machine tool.
Machine tool body: It’s the machine tool’s mechanical structure. It has the bed, column, workbench, spindle box, and feed mechanism. It gives the mechanical movement and support needed for processing.
Drive system: It gets the control system’s instructions. It makes the moving parts of each coordinate axis of the machine tool move. It can control the position and speed precisely. It’s mainly made up of servo motors, drivers, and transmission devices.
Auxiliary devices: Things like the cooling system, lubrication system, chip removal device, and protective device. They help the machine tool work and process normally.
Application fields
Mechanical manufacturing: It’s used to process all kinds of mechanical parts, like the cylinder block and cylinder head of car engines, and the wings and landing gear of planes.
Mold manufacturing: It can process all kinds of complex – shaped molds, like injection molds and stamping molds.
Electronic manufacturing: In making electronic equipment, it’s used for drilling and milling printed circuit boards (PCBs) and making precision parts of electronic components.
Medical device manufacturing: It can make high – precision medical device parts, like artificial joints and dental implants.
precision cnc machining is still changing. In about 3 years, new processing methods will come out. For example, it will change from single – axis motion to multi – axis linkage, and from a single – processing – mode machine tool to a combination of many processing modes. Different processing methods can mostly make parts for all fields.
