When selecting the relevant parameters for an external cylindrical grinder, the following factors need to be considered:
1. Processing accuracy: The processing accuracy of equipment is one of the important indicators for evaluating its performance. The machining accuracy mainly includes roundness, cylindricity, surface roughness, etc. When selecting, it is necessary to choose equipment with appropriate processing accuracy according to specific processing requirements.
2. Processing size range: The processing size range of the equipment refers to the outer diameter range and length range that can be processed. Different models of equipment have different processing size ranges, and when selecting, it is necessary to choose the appropriate equipment based on the size of the processed parts.
3. Grinding accuracy: The grinding accuracy of an external cylindrical grinder is an important parameter that represents the level of precision that the equipment can achieve when grinding workpieces. Grinding accuracy is generally described in the form of roundness, cylindricity, etc. Common accuracy levels include IT6, IT7, etc. When selecting an external cylindrical grinder, users need to choose the appropriate accuracy level based on their workpiece accuracy requirements and processing technology.
4. Other factors: In addition to the above factors, other factors such as equipment brand, price, after-sales service, etc. need to be considered. In addition, factors such as device stability and usability also need to be considered.
In short, the selection of relevant parameters for external cylindrical grinding machines requires comprehensive consideration of multiple factors, including machining accuracy, machining size range, grinding accuracy, brand, price, after-sales service, etc.
