What is grinding?
Grinding is a machining process used to remove surface material from workpieces to obtain the required surface roughness, precision and shape. During the grinding process, a grinding tool, usually a grinding wheel, is used to rotate at high speed and apply pressure on the surface of the workpiece to remove material from the workpiece to form the desired surface quality and geometry.
Here is the basic working principle of grinding:
1. Workpiece installation: First, the workpiece is installed on the workbench or fixture of the grinding machine tool to ensure that the workpiece is fixed and will not move. Clamping systems often come in a variety of designs to accommodate workpieces of different shapes and sizes.
2. Select grinding tools: Select the appropriate grinding tool (grinding wheel) according to the required surface roughness, accuracy and shape. Different types of grinding wheels are suitable for different materials and grinding requirements.
3. Set cutting parameters: The operator needs to set the cutting parameters of the grinding machine, including grinding speed, feed speed, cutting depth and coolant usage. These parameters influence the quality and efficiency of the grinding process.
4. Start grinding: Once the positions and parameters of the grinding wheel and workpiece are set, the grinding machine tool will start. The grinding wheel begins to rotate at high speed and exert pressure on the surface of the workpiece, removing material from the surface of the workpiece and forming the required surface quality and geometry. .
5. Cooling and lubrication: During the grinding process, coolant or cutting lubricant is usually used to lower the temperature, reduce wear and flush away chips.
6. Monitoring and measuring: Operators typically monitor the grinding process regularly and use measurement tools, such as surface roughness gauges or outside diameter micrometers, to ensure the surface quality and geometry of the workpiece meet specifications.
7. Completion of grinding: Once the workpiece surface reaches the desired surface quality and geometry, the grinding operation stops and the workpiece can be removed from the workbench or fixture and prepared for further processing or use.
Grinding is a common machining method widely used in the manufacturing industry to process workpieces of metals, ceramics, plastics and composite materials to obtain high-precision surface quality and precise dimensions. It is suitable for manufacturing various products such as precision parts, molds, cutting tools, bearings, gears, auto parts, aircraft parts, etc.
