●Customer：XXX Seiko Co., LTD （The name is specified）
●Processed products：φ12 DC power crown hole rear sleeve（The name is specified）
●Product material：red copper（The name is specified）
●Work tool and fixture：
OP10/OP20 adopts precision 6-inch hydraulic three-jaw chuck (external clamp)
●The technique remarks：
①Program set tool life management (automatic alarm can reduce the amount of scrap and excessive damage of tool after the customer has booked the processing quantity).
②OP20 is equipped with positioning device to ensure uniform milling (small raw parts margin)
③Equipped with high pressure pump (50kg)
●Machining accuracy: completely follow up the customer’s drawing
