Although we have to handle high-mix production, the conventional system required changeover time, which lowered the overall production efficiency. Therefore, we would like to increase the productivity by eliminating the changeover as much as possible.
Proposing a infeed unit that can handle multiple types of workpieces without changeover!
Achieving a 5% increase of the equipment operating rate and saving more operation time by using a stocker not requiring changeover !
- The customer’s system was operated 21 hours per day with 3 shifts for 3 times of changeover per day, resulting in a total of 60 minutes of machine down time.
By eliminating the 60 minute changeover time and keeping the system running, the system operating rate can be improved by 5%.
In addition, by allocating the man-hours for changeover to other processes, operators can have their time more and they can put their effort on other work.
‐ When listening to the customer’s issue, we found that the greatest point is how to eliminate the “changeover time” that hinders the productivity.
Therefore, we proposed to develop a system consisting of an muratec standard stocker and a specially designed pallet jig at a reasonable price to solve the issue.
Sales and SE departments of Muratec always offer the best proposal for individual customers after grasping their issues at the inquiry stage.
Productivity has been greatly improved by adopting high-mix production without changeover.
The on-site operational efficiency has also been much improved by eliminating the time for parts changeover.
Compared to the conventional parts feeder system, the acceptable stock quantity has increased, allowing for automatic operation for more than 4 hours, that leads to further productivity improvement.
The product in the case study introduced here is the CNC Turning Center ”MD120Ⅱ”
