An all-round success: Expert deburring and honing of rotors and stators
Sometimes a sintered part appears to be finished – but you are not satisfied with the result. Something is missing. The final touch so to speak. We have the solution for perfect deburring and honing of the edges, so that your sintered part gets rounded off.
Introductory remarks :
Burrs are considered to be an annoy-ing accessory when punching, preci-sion cutting and machining. In practice, there are various processes to remove them, but which is the right one for you? – electro-mechanical deburring, high-pressure water-jet deburring, me-chanical deburring with deburring mil-lers, drag finishing, thermal deburring, barrel finishing and brush deburring. René Gerber AG is quite clearly in fa-vour of the latter and finds brush de-burring a truly exciting process. Thus the company aims to advance the de-velopment of this technology in order to constantly offer an even better solu-tion to its customers.
Solution :
The Gerber brushing, polishing and deburring machines are used when it is necessary to deburr workpieces with indentations or pockets with high preci-sion and to round them off in a defined narrow tolerance range. At the same time, the surface roughness is quite significantly improved by the process. This technology is incorporated in a large number of precision components where absolute absence of burrs and an undamaged surface are a must. In this process, a brush, which is coated with an abrasive or which consists of bristles with incorporated abrasive grit, is allowed to slide over a sharp-edged workpiece. The result of this is an edge ounding. Since no secondary burrs arise during honing / deburring with brushes, the rounding is absolute-ly reproducible through the setting pa-rameters.
Brush deburring of milled, turned, sintered and punched parts with the BS Power The high performance BS Power transfer brush deburring system has one of two planetary brush heads and can simultaneously deburr and polish workpieces reliably and uniformly up to a diameter of 400 mm or also on both sides up to 180 mm. Neither heavy burrs nor the smallest contours consti-tute a barrier. The planetary brush heads were developed by Gerber and each have three large disc brushes with a diameter of 260 mm, forming a rotational circle of 570 mm. The ma-chine is universally applicable. Higher parts such as rotors, planetary gears and housings etc. can be reliably deburreds with this technology The BS Power is designed for high perfor-mance, so that hea
vily burrs resulting from punching, laser cutting, milling or turning are rapidly and reliably re-moved.
Its smaller sister, the BS Eco fills the gap as an efficient and cost-effective solution for smaller quantities with a diameter of up to 250 mm. The system is compact and reliable and optimally combines three work steps, selective deburring, edge rounding and surface polishing in one process.
