What is the difference between a grinder and a machine tool

Machine tool is a broad term that encompasses a wide range of mechanical equipment. Grinding machines are just one branch of machine tool equipment, which can be further divided into surface grinding machines, internal and external cylindrical grinding machines, universal tool grinding machines, thread grinding machines, machine tool track grinding machines, and so on

Machine tools are a general term, and grinding machines are a type of machine tool that can grind flat surfaces, shafts, or holes according to their functions

Grinding is a functional term for the "fine grinding" of grinding machines. It can also be done manually for "grinding" work, which belongs to precision machining

Machine tools such as centerless grinders have gradually replaced ordinary machine tools, because centerless grinders and other products have CNC devices, which are higher in configuration than ordinary machine tools, not to mention the differences in the working process

The machining process of the parts by the centerless grinder is strictly executed according to the parameters and actions specified in the machining program. It is a high-performance automatic or semi-automatic machine tool, which has the following obvious characteristics compared to ordinary machine tools:

Firstly, it is suitable for processing complex shaped parts

The centerless grinder can complete the processing of complex parts that ordinary machine tools cannot complete or cannot process at all. Therefore, it is widely used in aerospace, shipbuilding, mold and other processing industries

2. High machining accuracy

3. Stable and reliable machining

By implementing computer control and eliminating human errors, the machining consistency of parts is good, and the quality is stable and reliable.

Fourth, high flexibility

When the processing object changes, it is generally only necessary to change the CNC program, which reflects good adaptability and can greatly save production preparation time.

. On the basis of the centerless grinder, an automated manufacturing system with higher flexibility - FMS can be formed

Fifth, High Productivity

The centerless grinder itself has high precision and rigidity, and can choose favorable processing quantities. The productivity is high, generally three to five times that of ordinary machine tools. For the processing of certain complex parts, the production efficiency can be improved by more than ten times or even dozens of times.

6. Good working conditions

Machine tools have a high degree of automation, greatly reducing the labor intensity of operators and creating a better working environment.

7. Beneficial for modern management

The use of centerless grinding machines is conducive to the development towards computer control and management of production, creating conditions for achieving automation in the production process.

8. Large investment and high usage cost

9. Complex production preparation work

Due to the use of program control in the entire machining process, the preliminary preparation work for CNC machining is relatively complex, including process determination, program programming, etc.

10. Difficulty in Maintenance

The centerless grinder is a typical electromechanical integrated product with high technical content and high technical requirements for maintenance personnel.

The above is the difference between a centerless grinder and a regular machine tool
