Inline cleaning and deburring of punched components

A new, modular range of equipment for the degreasing, cleaning and deburring of components as they emerge from a coil- fed stamping press has been introduced by Bruderer UK, under a sole agency agreement with the German manufacturer, SLE Electronic. The systems can be factory fitted or retrofitted for operation with any press line, not just the high-speed presses manufactured by Bruderer in Switzerland. Continuous cleaning and deburring is essential for parts that are to be painted, plated, bonded, welded or soldered, as is often the case when manufacturing electronic components. The SLE equipment ensures flash and oil-free surfaces, with the user being able to specify the degree of cleanliness to suit the application. Appropriate modules are combined from SLE’s aqueous, chemical and mechanical cleaning systems, which are positioned on the output side of the press. Spraying, rinsing and steaming units are available to remove grease, oil and coolant, while scale, flashes and some burrs can be removed

during the cleaning cycle in high-pressure (180 bar) water jet units. The component strip then passes through the main de-burring module, whose brushes are mounted on a quick-change unit to assist rapid changeover to suit different strip widths from 20mm to 110mm. Edge chamfering and texturing of the component surface can be included in the deburring

cycle, and an integral measurement system checks for brush wear and adjusts their position to within ±0.15mm. Strip speed through the SLE modules is adjustable, up to 8m/min. SLE manufactures additional equipment for use both upstream and downstream of the automated punching, cleaning and deburring section of the press line. On the input side, it offers pre-cleaning and lubrication modules, including in-press

For cleaning discrete components, the company also manufactures units tailored to specific user requirements, complete with component handling systems.
