Machine tool is a very broad name. A large number of mechanical equipment can be called machine tool. Grinder is only one of the branches of machine tool equipment. Grinder is also divided into surface grinder, internal and external cylindrical grinder, universal tool grinder, thread grinder, machine tool rail grinder and so on.
Machine tool is a general term. Grinder is a kind of machine tool. It can grind plane, shaft or hole respectively according to function.
Grinding is a functional appellation of "fine grinding" of grinding machine. In addition, you can also do "grinding" by hand, which belongs to finish machining.
Machine tools such as centerless grinders have gradually replaced ordinary machine tools, because centerless grinders and other products have numerical control devices, which are higher than ordinary machine tools in terms of configuration. It is not a grade, let alone the difference in the working process.
The machining process of parts by centerless grinder is carried out in strict accordance with the parameters and actions specified in the machining program. It is a high-efficiency automatic or semi-automatic machine tool. Compared with ordinary machine tools, it has the following obvious characteristics:
1、 It is suitable for machining complex special-shaped parts
Centerless grinding machine can complete the processing of complex parts that are difficult or impossible to be processed by ordinary machine tools. Therefore, it is widely used in aerospace, shipbuilding, mold and other processing industries.
2、 High machining accuracy
3、 Stable and reliable processing
Realize computer control, eliminate human errors, good processing consistency of parts, stable and reliable quality.
4、 High flexibility
When the machining object is changed, generally only the NC program needs to be changed, which reflects a good adaptability and can greatly save the production preparation time. On the basis of centerless grinder, an automatic manufacturing system FMS with higher flexibility can be formed.
5、 High productivity
Centerless grinding machine itself has high precision and rigidity. It can choose favorable processing dosage and high productivity, which is generally three to five times that of ordinary machine tools. For the processing of some complex parts, the production efficiency can be increased by more than ten times or even dozens of times.
6、 Good working conditions
The machine tool has a high degree of automation, the labor intensity of operators is greatly reduced, and the working environment is good.
7、 Conducive to management modernization
The use of centerless grinding machine is conducive to the development of computer control and management of production, and creates conditions for the automation of production process.
8、 Large investment and high use cost
9、 Complex production preparation
Because the whole machining process adopts program control, the preliminary preparation of NC machining is more complex, including process determination, programming and so on.
10、 Maintenance difficulty
Centerless grinder is a typical mechatronics product with high technical content and high technical requirements for maintenance personnel.
The above is the difference between centerless grinder and ordinary machine tool. There are still quite a lot of contents, which reflects that there are still many advantages of centerless grinder products
