External cylindrical grinder is a machine tool used for grinding the outer cylindrical surface, outer conical surface, and step shaft end face of workpieces. Its technical features mainly include high-precision grinding wheel spindle bearings, the use of dynamic pressure bearings to maintain high bearing stiffness, the use of cross roller rigid guide rails for the grinding wheel frame, the use of rotary oil cylinders for semi-automatic feed mechanisms, the design of the tailstock shaft system without gaps and with high stiffness, and the installation of auxiliary devices such as grinding indicators and coolant filters.
These technical features are crucial for improving the machining accuracy and efficiency of cylindrical grinders.
1. High precision grinding wheel spindle bearings and dynamic pressure bearings can ensure the stability and accuracy of equipment during high-speed rotation.
2. The cross roller rigid guide design of the grinding wheel rack guide rail makes the movement of the grinding wheel smoother, reducing vibration and errors during the grinding process.
3. The design of semi-automatic feed mechanism and tailstock shaft system has also improved the operational convenience and machining accuracy of the equipment.
4. The auxiliary devices such as grinding indicators and coolant filters further improve the processing efficiency and finished product quality of the equipment.
In summary, the technical characteristics of cylindrical grinding machines have a significant impact on their machining performance and finished product quality. When selecting equipment, its technical features should be fully considered to meet processing requirements.
