● Process product：Intermediate Sleeve（The exact name is specified by the customer）

● Product material：40Cr（The exact name is specified by the customer)

● Work-piece fixture：
①OP10 Adopting a precision 6-inch hydraulic three jaw chuck (External clip)
②OP20 Adopting a precision 6-inch hydraulic three jaw chuck（bracing）

● Technology note：
①Program to set up the tool life management (After the customer has pre-set the machining quantity, it will automatically give an alarm, reducing the scrap rate of products and the excessive damage of tools).
②Install a pallet to blow water and a gantry loader to blow air.
③Install high-pressure water pump (45 meter head)

● Processing accuracy requirements:
As required by the drawing
