CNC (CNC machine tool) is the abbreviation of Computer digital control machine tool (Computer digital control), which is an automated machine tool controlled by a program.
The control system can logically process programs with control codes or other symbolic instructions, and decode them through the computer, so that the machine tool can perform the prescribed actions and transform the blank into semi-finished parts. -finished thanks to cutting tools. Virtual CNC machining intelligent inverse simulation system is a set of software that simulates real CNC controllers and machine tools through inverse post-processors and virtual machine tools, and tests the CNC machining process on the computer. And it simulates machining CNC programs based on machine, tool, roughing and fixture information, and can identify errors in the machining process.
CNC technology (English name: Numerical Control, abbreviation: NC) refers to the technology that uses digital instructions composed of numbers, words and symbols to achieve action control of one or more mechanical equipment. CNC generally uses a general-purpose or special-purpose computer to achieve digital program control. Therefore, CNC is also called computer numerical control (computer numerical control), or CNC for short.
CNC machine tool control unit
The operation and monitoring of CNC machine tools are all carried out in this CNC unit, which is the brain of the CNC machine tool. Compared with ordinary machine tools, CNC machine tools have the following characteristics:
● High processing precision and stable processing quality;
●Can perform multi-coordinate connections and process parts with complex shapes;
●When changing processing parts, usually only the CNC program needs to be changed, which can save production preparation time;
●The machine tool itself has high precision and rigidity, can choose favorable processing quantities, and has high productivity (generally 3-5 times that of ordinary machine tools);
●The quality requirements for operators are higher and the technical requirements for maintenance personnel are higher.
Structure of CNC machine tool
●Host
This is the subject of CNC machine tools, including machine bodies, columns, spindles, feed mechanisms and other mechanical components. It is a mechanical component used to complete various cutting processes.
●CNC device
It is the heart of CNC machine tools, including hardware (printed circuit boards, CRT monitors, key boxes, tape drives, etc.) and corresponding software. It is used to input digital part programs and complete input information storage and data transformation. and insertion complete the operations and implement various control functions.
●Drive device
It is the driving component of CNC machine tool actuator, including spindle drive unit, power unit, spindle motor and feed motor, etc. It drives the spindle and the power supply via an electric or electro-hydraulic servo system under the control of a CNC device. When multiple flows are linked, the processing of positioning, straight lines, plane curves and spatial curves can be completed.
●Auxiliary devices
Some necessary supporting components of CNC machine tools to ensure the operation of CNC machine tools, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip evacuation devices, exchange tables, CNC turntables and CNC dividing heads, as well as cutting tools and monitoring and detection devices.
●Programming and other auxiliary equipment
It can be used to program and store parts outside of the machine. Since the world’s first CNC machine tool was developed by the Massachusetts Institute of Technology in 1952, CNC machine tools have been widely used in the manufacturing industry, especially in the automotive, aerospace and military industries. CNC technology has been widely used in both hardware fields. and software, are developing rapidly.
The treatment center is even more impressive
The machining center is a highly automated multifunctional CNC machine tool with a tool magazine and automatic tool changer. After the workpiece is clamped once on the machining center, it can process multiple processes on more than two surfaces and has multiple tool change or tool selection functions, greatly improving production efficiency .
Machining centers are divided into two categories: boring and milling and turning according to their processing procedures. According to the number of control axes, they can be divided into three-axis, four-axis and five-axis machining centers.
Daguang focuses on providing solutions such as precision CNC machining services (3-axis, 4-axis, 5-axis machining), CNC milling, 3D printing and rapid prototyping services.
