As critical equipment for high-precision machining, the long-term stable operation and machining accuracy of double disc grinding machines directly impact the consistency of workpiece quality. To ensure the equipment remains in optimal working condition, implementing a systematic plan for regular inspection and adjustment is essential.
Periodic inspection forms the foundation of precision maintenance. Key geometric tolerances must be cyclically verified, including but not limited to: - Flatness and runout of grinding wheel faces - Parallelism between both grinding wheel faces - Stability of the worktable feed mechanism These inspections require precision instruments such as leveling instruments, dial indicators, and standard gauges. Objective assessment of current precision status through measurement data enables timely detection of minor deviations caused by wear or deformation.
Targeted adjustments based on inspection data are central to restoring precision. If parallelism is out of tolerance, adjust the axial positioning of the grinding wheel spindle. Insufficient flatness may require fine dressing of the grinding wheel or even inspection of the spindle bearing clearance. All adjustments must strictly adhere to rigorous process specifications to ensure coordinated and stable operation of moving components post-adjustment. For natural wear resulting from prolonged use—such as wear on guideways or lead screws—more extensive mechanical repairs or component replacements are required to achieve fundamental precision restoration.
Establishing comprehensive calibration and maintenance records is essential for effective implementation. Detailed documentation of each inspection's data, adjusted parameters, and replaced components not only provides historical reference for future maintenance but also facilitates analysis of precision trends. This enables a shift from reactive repairs to proactive prevention. Only through such a cyclical closed-loop management system can the machining accuracy and reliability of double disc grinding machines be effectively safeguarded, laying a solid foundation for high-quality production.
