Automated Deburr of Hydraulic Sleeve Internal Elements

The sponsor manufactures the hydraulic sleeves used to move fluid from one control port to another in hydraulic valves. Precision grinding and honing the inner surfaces of the sleeves raises small burrs on interior edges that prevent smooth operation. Burrs are removed manually, which is labor-intensive and time-consuming. The machine designed moves hydraulic sleeves up and down while a motor-powered steel brush deburrs the inner surface of the sleeve from above, requiring no human interaction after set up. To ensure that the device is compatible with all hydraulic sleeve sizes, it has been designed to accommodate interchangeable brush sizes, and the user interface allows input of various sleeve parameters.The automated deburring machine allows users to load and secure a hydraulic sleeve, and then to select a preset deburring option or manually input sleeve parameters. The machine is oil and water resistant, reduces hydraulic sleeve touch time, and meets sponsor requirements for safety and efficiency.
