This customer is a famous water meter enterprise in Zhejiang. Water meter products from the customer are exported to Japan and the United States. This customer has been using our chucks since 2014. The customer started with trial one set, then 3 groups of units (9 sets). Now all related products on site are machined by indexing chucks. There are more than 60 indexing chucks from our company. To quote the customer boss' original words, "After using our indexing chuck, the machining cost of a product has dropped from 0.92 yuan to 0.37 yuan.” The machining cost has been greatly reduced. In order to match the indexing chuck project, the customer rejected the imported special equipment (Special machine, slow model changing, machining precision can not meet the requirements) and added the same number of CNC lathes.
