That is a savings of 825 pieces per month and we can make the production quantity with only one shift in operation. That gave us a total [savings] of $1,700 [a month]!

We run the machines with your Drawdown Chucks 24 hours/day and 6 days/week. Last year we were 24/7 with no problems.

When you are trying to hold .0002” just any workholding device will not do. To me this says a lot for the craftsmanship of the product you have supplied to us.
