Numerical control milling machine is a kind of automatic machining equipment developed on the basis of general milling machine.Numerical control milling machine is divided into two categories: no - strip and strip.CNC milling machine with cutter library is also known as machining center.Functional featuresIn addition to the characteristics of ordinary milling machine, CNC milling also has the following characteristics:
Numerical control milling machine is a kind of automatic machining equipment developed on the basis of general milling machine.Numerical control milling machine is divided into two categories: no - strip and strip.CNC milling machine with cutter library is also known as machining center.Functional featuresIn addition to the characteristics of ordinary milling machine, CNC milling also has the following characteristics:
1. Good adaptability and flexibility of parts processing, able to process parts with especially complex contour shape or difficult to control size, such as mold parts and shell parts;
2. Can process parts that cannot be processed or difficult to be processed by ordinary machine tools, such as complex curved parts described by mathematical models and three-dimensional curved parts;
3. Be able to process parts that need to be processed in multiple processes after the first clamping and positioning;
4. High machining accuracy, stable and reliable machining quality, the pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1 knem. In addition, the numerical control machining also avoids the operating error of operators.
5. High degree of production automation can reduce the labor intensity of operators.It is beneficial to the automation of production management.
6. High production efficiency. Generally, the CNC milling machine does not need to use special process equipment such as special fixture.Secondly, the numerical control milling machine has the function of milling machine, boring machine and drilling machine.In addition, the spindle speed and feed speed of the CNC milling machine are infinitely variable, so it is helpful to select the optimal cutting amount.
General CNC machining usually refers to precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines.
Advantages and disadvantages of CNC
CNC machining has the following advantages:
To greatly reduce the number of tooling, machining parts with complex shapes does not require complex tooling.If you want to change the shape and size of the parts, you only need to modify the parts processing procedures, suitable for new product development and modification.
The machining quality is stable, the machining precision is high, and the repeat precision is high, which meets the requirement of the aircraft.
Production efficiency is higher in the case of multiple varieties and small batch production, which can reduce the time of production preparation, machine adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.
I can process complex forms with conventional methods, and can even process parts that cannot be observed.
The disadvantage of nc machining is the high cost of machine equipment and high level of maintenance personnel.
Numerical control lathe, turning center, is a high - precision, high - efficiency automatic machine tool.Equipped with multi-station cutter tower or power cutter tower, the machine tool has extensive adding process performance, can process linear cylinder, oblique line cylinder, circular arc and various threads, slots, worm and other complex workpieces, has linear interpolation, arc interpolation of various compensation functions, and in the mass production of complex parts has played a good economic effect.The characteristics of Numerical control machine tool is the abbreviation of digital control machine tool.The control system can logically process a program with control coding or other symbolic instructions and decode it so that
Compared with ordinary machine tools, nc machine tools have the following characteristics:
①Processing precision of is high, with stable processing quality;
②Can be multi-coordinate linkage, can process the shape of complex parts;
③When parts of processing are changed, the nc program is usually changed to save production preparation time.
④Machine itself has high precision and rigidity, can choose favorable processing dosage and high productivity (generally 3~5 times of ordinary machine).
⑤Machine automation degree high, can reduce labor intensity;
⑥Has higher requirements for the quality of operators and higher technical requirements for maintenance personnel.
