Advanced deburring systems enable higher productivity

RSA GmbH & Co KG, Germany, is a specialist in cutting and deburring systems for tube and pipe manufacturers. The company has recently supplied a Turnamat deburring system to a manufacturer of agricultural machines that uses hydraulic tube products. During pre-production of hydraulic tubes, the company had previously used a file to remove outside burrs and a spot facer to remove inside burrs. However, the company now uses the Turnamat deburring system to carry out these procedures with far more efficiency. Using this machine, a high performance brush operates as a tool. In addition to the rotating movement, the high performance brush

makes a second rotation: it turns on its own axis. This second rotation assures complete deburring of the tube and section edges without having to turn the workpiece manually. According to the agricultural machine manufacturer, the advantages of the system are the reproducibility of deburring results, simpler handling for the operator, and a drastic reduction of the deburring costs. It is possible to reduce the deburring time per end face from 30 to 4 seconds. Based on the daily production of about 700 workpieces, the amortization period for the machine was less than 2 months. In many areas of pre-production, especially within the automotive supply industry, where high quantities are

reached, the method of deburring with high performance brushes is well-established. The necessity of a perfect quality and highest assembly simplification do not permit deburring methods that are dependent on the qualification of the operator. RSA has developed different fully automatic deburring systems, especially for high quantities. However, there is much potential for rationalization in this area, with improved interlinking of different working steps. The direct interlinking of deburring systems with preceding saws from other suppliers, or the interlinking of cleaning modules, can lead to lower processing times.

Normally, the deburring time is about 3 seconds also in case of complex workpieces belts, deburring wheels and similar methods. Changeovers are easy and can be completed within minutes with four sets of tools covering a 5 / 16 " to 2" diameter range. Eight spindle speeds are available from 760 to 3,920 RPM and the maximum stroke is 1 1 / 4 ". These end-finishing machines are easy to operate and come with a variety of accessory equipment and tooling options.

 The Turnamat deburring system is suitable for unwieldy workpieces such as bent tubes. Inside and outside burrs are removed reliably in one work process without having to turn the workpiece manually

New tube and rod end-finishing machine

Manchester Tool & Die Inc, USA, now offers the Pines model 660 tube and

rod end-finishing machines for fast and simultaneous deburring, ID/OD chamfering, and facing. Model 660 includes two models, a manually operated and an air operated machine, for finishing up to 1,500 ends per hour and 1,875 ends per hour respectively. These end-finishing machines offer cost savings by freeing lathes and other machines on a wide range of work. Model 660 can also increase production and improve accuracy compared to abrasive
