Pour side of arris of round razor blade equably with abrasive brush

In the production process of cutting tool product, to improve the performance characteristics of the product and exterior quality, raised certain craft requirement to the circle falling by the side of arris. The round technique side implementation arris is more, answer to ask according to producing condition and quality, the element such as feasibility of cost of efficiency of production of integrated consideration, production, equipment decides specific means. The round basic technology principle side arris is to use the medium effect that contains abrasive at workpiece arris edge, form particular opposite movement, with stuff of edge of purify part arris. The action kind that contains abrasive medium and workpiece decided to pour the complex level of round craft and equipment. In bit treatment, using abrasive brush to undertake arris edge pours a circle is handy and a kind of easier implementation, practical technique. The medium that appliance has certain kinetic energy (be like abrasive brush) when having a circle to workpiece arris edge, measure of acquisition round horn radius often disperses the gender is bigger (the R of round horn radius after like actual measurement some razor blade pours a circle, rmax of the biggest round radius can amount to the 2 times above of Rmin of the smallest round radius, dimension changes limits designs requirement) more than, and work check form is more complex, the dispersive sex of round dimension is bigger. Accordingly, the uniformity that assures round radius dimension is to raise arris edge to pour round craft feasibility and practical key. In round treatment falls by the side of arris, medium is periodic to the purify action of workpiece arris edge undertake repeatedly, in each treatment cycle, medium the material side the arris of purify minim bulk. The main factor that affects round dimension uniformity includes medium effect the opposite motion speed of the active force P at workpiece, medium and workpiece (include speed V and the included angle Q) with arris edge, work different position by the time of medium action T. The metabolic rule of afore-mentioned each elements is like a graph respectively 1, graph 2, the graph is shown 3 times. By the graph knowable, the gets medium action at each o'clock rate on workpiece is basic and equal, and different position gets work the time of medium action and active force are variable element. Accordingly, after can making machine through adjusting effect time and active force everywhere the round radius of arris edge tends consistent. Graph the graph of 1 medium two kinds of circumstances to on workpiece arris edge a bit active force 2 medium are different to workpiece the effect time of place pursues the opposite motion speed of 3 medium and workpiece (oversight workpiece moves) graph the osculatory process of 4 medium and workpiece is in the osculatory process of medium and workpiece, usable contact quantity represents the effect time T of active force P and different to workpiece position integratedly, contacting a process is the course that osculatory quantity follows time to change. When using specific athletic means, the change that can measure to the contact has accurate description. Below experiment condition, the osculatory process that measures denotive medium and workpiece with the contact in an action cycle is shown 4 times like the graph. The test of round treatment that has to a few kinds of razor blade proves, contact a quantity through pressing afore-mentioned principles to adjust, the inhomogenous sex that can make R of round horn radius is worth [(Rmax-rmin)/rmin] × 100% by original prep above 100% reduce 30% the left and right sides.
