Sawing centre solution for perforated tubes

RSA, a specialist for solving sawing tasks for pre-production, has developed a sawing centre that reduces the high labour and material costs for the sawing of perforated random lengths. In the production of racking systems, the precise distance between each perforation is essential, but naturally there are intolerances between perforations during the manufacturing of perforated tubes. High production costs of the punched pieces are the consequence. In order to precisely maintain the position and tolerance of punched parts, it has fi RSA’s Rasacut OC automatic sawing centre saws perforated tubes and ejects faulty perforations

always been necessary to use semi- automatic solutions. Time-intensive manual measuring of punched tolerances and adjustment of the saw length stop only allows for a low yield. Companies using a fully automatic saw can achieve higher yields, but consequently need 100 per cent checking of the fixed length, leading to a higher acceptance rate of rejections due to the alteration of the perforation. The Rasacut OC sawing centre from RSA works quickly and precisely. Tubes are automatically singled from the bundle and transported via a gripper to the saw. This highly precise feeding is controlled by an optical system that automatically measures the tolerances of the individual punching, and ensures precision between the pressings and the tube end according to the set parameters. The machine includes fully automatic deburring, cleaning and drying of the fixed lengths. Certain parts in the random material which show unsuitable tolerances between the pressings are rejected and removed. This eliminates the need for

additional 100 per cent checking and results in fewer rejections. The standard equipment of the Rasacut OC is suitable for tube diameters from 10- 90mm, and fixed lengths from 30mm to 3,000mm.
