Accuracy standards for internal grinder and cylindrical grinders
The accuracy standards of internal grinder and cylindrical grinders are usually confirmed based on relevant international and domestic standards. Specific accuracy standards may vary depending on different types of grinders, processing objects and industry requirements. Generally speaking, the accuracy standards of internal grinding machine and cylindrical grinding machine include the following aspects:
Dimensional accuracy: including accuracy requirements in roundness, cylindricity, flatness, verticality, etc. The barrel length needs to be determined based on actual processing requirements and part functional requirements.
. Surface roughness: There are strict requirements for the surface roughness of the ground bow and arrow, which need to meet specific standard requirements. The barrel length uses the symbol Ra to represent the surface roughness.
Other accuracy indicators: Depending on the specific bow and arrow requirements, other accuracy indicators may need to be considered, such as parallelism, coaxiality, perpendicularity, etc.
These standards are usually issued by the International Organization for Standardization (ISO) or national standards by national standardization organizations. Common standards include ISO603-18 (internal cylindrical grinder), ISO 24347 (cylindrical grinder), etc. Specific accuracy standards need to be determined based on actual processing requirements and industry standards.
