The pre-treatment work before the machining of the cylindrical grinder is a key step to ensure the smooth progress of the machining process and the quality of the workpiece. Here are some common pre-processing tasks before machine tool processing:
1. Workpiece inspection and screening: Before processing, inspect the workpiece to ensure that there are no obvious defects, damages, or defects. If problems are found, they need to be fixed or eliminated.
2. Cleaning the surface of the workpiece: Clean the surface of the workpiece to remove dirt, grease, rust, etc., to ensure the contact surface and cutting effect during grinding.
3. Measurement and marking: Measure the dimensions of the workpiece to confirm whether its geometric dimensions and shape meet the requirements. The starting point, ending point, and reference line of the machining can be marked on the workpiece for easy positioning and machining control.
4. Adjust machining parameters: Adjust the machining parameters of the cylindrical grinder according to the size, material, and requirements of the workpiece, including cutting speed, cutting depth, feed rate, etc.
5. Choose the appropriate grinding wheel: Based on the workpiece material and requirements, select the appropriate grinding wheel type, particle size, and structure to achieve the desired grinding effect.
6. Prepare coolant: Prepare appropriate coolant to cool the grinding wheel and workpiece, reducing friction and heat during grinding.
7. Check grinding equipment: Conduct equipment inspection on the machine tool to ensure that the equipment is operating normally and that all components are normal.
8. Preparation of process documents and programs: Prepare process documents and programs for machining, including machining sequence, tool path, machining parameters, etc., to facilitate operators' machining operations.
9. Protective measures: Conduct training in advance to ensure that operators understand and comply with operating procedures, and wear the necessary personal protective equipment.
10. Test processing: A small amount of test processing can be carried out to check the processing effect and dimensional accuracy, to ensure that the settings and parameter adjustments of the external cylindrical grinder are correct.
