It not only improves productivity but also on improving product quality and optimize the work environment plays a vital role in this but also on the turret design many new requirements, such as how to make it run faster and reliable, so change Knife time as short as possible in exchange for its efficiency, making the structure more simple and cheaper. To make these more advanced CNC lathes better play the role of these issues that we have to go to resolve. It is discussed in this article such a use PLC to control the tool change process, new hydraulic turret. The paper includes the design of the hydraulic system to achieve the movement of disengagement and engagement chainring knife to achieve coarse location, while controlling for fine positioning of the knife is inserted and pulled the plug on the spline shaft; mechanical transmission part of the design, including design including shafts, hydraulic cylinders, gears, gear plate and a variety of static and dynamic sealing devices; When designing PLC control program in order to achieve the nearest turret tool selection and turret lights are turned all pockets bright look, its debugging to test its validity after completion.
