Stable quality is achieved through stable machine conditions
― What we can do now to prevent performance degradation ―
Are issues like the following occurring in production sites?
・One day, the defect rate suddenly increased.
・Even though machines are operating, the quality is unstable for some reason
・Although periodic maintenance is performed but whether it is sufficient is unknown
・The cause cannot be identified, handling at the production site is delayed
These issues may be caused by the accumulation of slight performance degradations that are not visible.
Please check the latest information first.
Performance degradation starts in areas that are not visible
Changes in machine performance do not always appear as obvious as stops or errors.
・Dirt that accumulates little by little
・Minor deviations in operation
・Slight changes caused by daily operation
These changes are hard to notice during normal operation and surface as quality problems when noticed.
Is the periodic maintenance enough?
Of course, periodic maintenance is important. However, under different operating conditions for each production site or each line, it is important to consider whether maintenance only based on fixed usage periods is sufficient in line with the actual operating conditions.
However, there are limits in determining "when, where, and to what extent" maintenance should be performed based on only intuition and experience.

These materials detail how to approach to these issues along with our solutions.
Main points of these materials
・Why does machine performance deteriorate without being noticed
・Essential concepts that should be kept in mind to prevent performance degradation
・Key points of preventive maintenance for ensuring stable quality
・Hints to eliminating depending on skills of individuals for maintenance
Concepts and hints to perform this are summarized.
