B. Flow Through - A flow through system is designed to be either semi-automatic orfully automatic. tools are driven by two, 3 horsepower brake motors. The motor assemblies aremounted on a single tool slide to ensure alignment. The brush/motor assemblies are adjustable to accommodate a range of extrusion lengths. A reversing brake motor is utilized to provide the necessary brush direction change in order to provide 360 degree deburring. After passing through the top half of the brush, the motor is braked and rotation is reversed. The extrusions are then brought back through the top half of the brush again to complete the deburring cycle. 1. 2. Semi-Automatic flow through systems require operator involvement forloading and activating the system. Finished parts are automatically unloaded off of the opposite end of the system. A total of four brushing heads are used in this system. Two 2 horsepower motors per side, rotating counter to each other provide the deburring action. The motors are saddled on a tool slide for precise alignment and adjustability. Fully Automatic systems are designed to be incorporated into aproduction line. The deburring concept follows that of the semi-automatic flow through system. The part transfer and clamping mechanism is designed to accept the extrusion as it is conveyed. Conclusion Fiber abrasives are an effective media for end deburring aluminum extrusions.When formatted into disc brushing tools, the multidirectional rotation of the disc can be utilized by applying it on a machine based system. An end deburring system presents the extrusion to the brush in a controlled and precise manner. Systems are available in manual, semiautomatic, and fully automatic designs to meet virtually any production need. They offer increased productivity, enhanced safety, and consistent, high quality deburring.
