The actual efficiency improvement of the automation transformation of the grinding machine production line usually ranges from 40% to 80%, depending on the automation level of the transformation, product complexity, clamping efficiency, and the matching degree of process rhythm.
1, Efficiency improvement intervals for different levels of automation
(1) Single machine automation transformation (replacing manual loading and unloading with truss/articulated robotic arms)
Efficiency improvement of about 40% -55%, eliminating the auxiliary time of manual clamping, fatigue fluctuations, and downtime caused by misoperation;
Suitable for batch production of large and regularly sized workpieces, such as automotive bearing rings and hardware fasteners for grinding and processing.
(2) Whole line linkage automation (including automatic loading and unloading, online measurement, automatic grinding wheel leveling compensation, and defect sorting)
Efficiency improvement of about 65% -80%, integration of grinding and processing processes, elimination of time loss caused by intermediate waiting and manual intervention;
Require that the beat difference between each workstation on the entire line does not exceed 10%, otherwise bottleneck workstations will lower the overall improvement effect.
2, Efficiency loss correction for actual implementation
(1) The impact of non device core links
Insufficient precision of the workpiece pre-processing benchmark results in prolonged automatic clamping and alignment time, and actual efficiency is 10% -15% lower than the theoretical value;
The matching degree between grinding wheel consumables and automatic leveling system is poor, and the leveling cycle conflicts with the processing beat, resulting in additional downtime adjustment time.
3, Exception situations for scene adaptation
Small batch multi variety production scenario: When switching between workpiece batches, automatic tooling and fixture switching, as well as importing processing programs, take up time and increase efficiency by only 20% -35%;
Irregular and complex workpieces (such as aviation blade grinding): The initial positioning compensation debugging cycle is long, and the efficiency improvement is less than 50%. After stable operation, it can reach more than 60%.
