The development of numerical control technology is based on numerical control machine tools, and the development of numerical control machine tools has experienced five generations of numerical control systems such as electronic tubes, transistors, small-scale integrated circuits, large-scale integrated circuits, and small computers and microprocessors. The hardware-based numerical control system implemented by electronic circuits is generally called ordinary numerical control system, or NC for short. System, referred to as CNC (fourth generation) and MNC (fifth generation). Numerically controlled (CNC) machining is a manufacturing process that many industries have incorporated into their manufacturing processes. This is because the use of CNC machines can increase production. It also allows for a wider range of applications than manually operated machinery. Is cnc a CNC lathe or a machining center?
CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting the inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces of any taper angle, complex rotating inner and outer surfaces, and cylindrical and conical threads, etc., and can perform grooving, drilling, reaming, reaming Holes and borings, etc. Whereas in CNC machining, the machine operates through a numerical control, in which a software program is specified to control the object. The language behind CNC machining, also known as G-code, is used to control various behaviors of the corresponding machine, such as speed, feed rate, and coordination. To put it simply, CNC machining centers do not include CNC lathes and CNC milling machines. CNC machining centers are also in the format of CNC milling machines, but only have tool magazines. Therefore, CNC is a machining center, which is different from CNC lathes in the following points:
1. Structural difference:
CNC machining centers are at least three-axis controlled, while CNC CNC lathes are two-axis controlled.
2. Difference between machining tools:
The CNC machining center has a tool magazine, and the CNC CNC lathe uses a tool holder. There are more types of tool magazines in CNC machining centers than those of CNC lathes. There are disc type, bucket hat type, chain type, flying saucer type, synchronous type, etc. The tool capacity of most tool magazines is higher than that of CNC lathe tools. The tool capacity of the rack is large.
3. Different processing range
The machining range of CNC machining centers is larger than that of CNC lathes. CNC CNC lathes are mainly used to process rotary parts.
4. Programming differences
CNC machining center and CNC CNC lathe programming are similar in some aspects, but CNC machining center programming is more complex.
CNC machining can pre-program the speed and position of machine functions and run them through software in repetitive, predictable cycles with little or no human intervention. During CNC machining, CAD drawings in 2D or 3D are conceived and then converted into computer code for execution by the CNC system. After entering the program, the operator test-runs it to make sure there are no errors in the coding. Thanks to these capabilities, the process has been adopted in all corners of the manufacturing industry, with CNC machining being especially important in the production of metals and plastics. The advantages of CNC machining are mainly reflected in the following points:
1. CNC can automatically process. CNC machining usually refers to precision machining that is numerically controlled by a computer. Therefore, it can be controlled by the program instructions of the CNC machine tool, and the whole processing process is automatically carried out according to the program instructions. The machine tool has a high degree of automation, which greatly reduces the labor intensity of workers.
Currently, many CNC machines can run unattended throughout the machining cycle, freeing up the operator for other tasks. This has several side benefits for CNC users, including reduced operator fatigue, fewer errors due to human error, and consistent and predictable machining times for each workpiece.
2. High precision CNC machining. The second biggest advantage of CNC technology is the consistency and precision of the workpiece. Typical accuracies of today's CNC machines have reached two thousandths to four thousandths of an inch or 0.05 to 0.10mm, with repeatability close to or better than eight thousandths of an inch or 0.02mm. This means that once a program is validated, two, ten or a thousand identical parts can easily be produced with the same precision and consistency. Mass production can be achieved, and product quality is easy to control.
3, CNC machining flexibility is strong. Since these machines are run by computer programs, running different workpieces is as simple as loading different programs. This also brings another benefit, fast conversion. Since these machines are very easy to set up and run, and programs can be loaded easily, they have very short setup times.
4. High CNC machining efficiency. CNC machining can carry out multi-coordinate linkage, and can process complex zero points. When the shape and size of the parts need to be changed, only the NC program needs to be changed, saving production preparation time.
5. CNC machining can process complex profiles that are difficult to process by conventional methods, and even process some unobservable machining parts.
6. In the case of multi-variety, CNC small batch production, madeinnoble.com has higher production efficiency, which can reduce the time for production preparation, machine tool adjustment and process inspection, and reduce cutting time due to the use of the optimal cutting amount.
The above are the six advantages of CNC machining and whether CNC is a CNC machine tool or a machining center.
