Outside Tube Scarfing System Rotoscarf An outside tube scarfing system with regrindable carbide inserts or indexable carbide inserts for tube O.D. starting at 12,7mm up to 101,6mm (1/2"-4") optional up to 168mm The objective for this unit was to provide the user a system that will run at least one shift without manual tool change. Furthermore our intention is to supply high quality and performance at the best price per cutting edge. The Princip is simple: Three carbide cutting blades are located in a circular tool head. Each of the cutting blades oscillates with the complete length of its cutting edge over the tube surface. The result is a perfect surface finish and a long tool life. Performance and Advantages: Average blade lifetime: 3hours @ 120m/min weld speed. Non Stop O.D. deburring for one shift. Tool change between the 3 inserts only by pressing a push button; a tool change is done in 2 seconds. The carbide cutting blades can be reground up to 30 times Easy regrinding: Only the front surface needs to be reground. The average costs to regrind a blade are between 2 and 3 euros. The simplicity of the regrinding process allows the user to try out different angles to optimize the cutting process and not least to increase performance. Perfect surface finish of the deburred area. Easy and fast tool cassette change. Cassettes with different relief angles are available (for aluminized or galvanized strips). Connection to the tube mill for automatic tool lifting or starting in automatic mode. 3 O.D. range tool heads: 12,7-40mm; 25-72mm and 65-101,6mm (other sizes on request). Cutting heads also availabe for indexable inserts of the SNMX/G-type (see page 11+12) 13

Tube Mill Entry Equipment Strip Shaving Unit Perfect strip edge preparation increases welding quality and prevents rejects. Strip width 55-300 (standard) Welding aluminized strips is very difficult because of many reasons: Aluminium melts at the strip edges and interferes the welding process and decreases the quality of the weld. Drops of liquid aluminium may destroy the impeders and can also built up weld beads, which can get loose and destroy the tooling downstream. I.D. and O.D. tube deburring is sometimes difficult and costly due to many tube mill stops caused by a untreated strip.we have designed our STRIP EDGE SHAVING MACHINE which will not only shave the edges... The Alpha Metall Strip Shaving Unit is specially designed to shave off the coatings also from the upper and lower side of the strip. All 3 Stations of the Strip Shaving Unit are equipped with standard TiN-coated TCMT carbide cutting inserts. The Strip Edge Shaving Unit is supplied with 3 stations featuring: Lead in and exit rollers. Side guide rollers adjustable through an excentric bolt. Top and bottom guide rails. One horizontal main adjustment to set the 6 tool stations to the strip width (95-300mm, other sizes on request). Horizontal adjustment for the strip centerline (+/- 12,5mm) First station shaves the upper part of the strip. Second station shaves the edges of the strip. Third station shaves the lower part of the strip. Micrometer adjustment of the cutters. Automatic sequence for opening and closing the side guide rollers, the top guide rails and the cutting tools to free the strip when the weld butt passes or for fast strip size change. 14

Chip Treatment Bead Chopper / Chip Shredder During the outside diameter scarfing process a continuous chip is being produced which is either reeled up or falls on the floor. The control and the removal of this chip is a problem due to the risk of accidents. The problem increased with the development of tube mills operating at weld speeds up to 200 metres per minute. view on the cutting blades The chips are guided into the weld seam shredder which can be placed in front of the scarfing station(s) without interfering tube mill operation. During the cutting progress the chip is slightly pulled into the shredder. That means less danger for the tube mill operator. Our Weld seam shredder is capable to process chips with a cross section up to 40mm². The main advantage is, that the chip volume is 20 times less than that of reeled chips and staff is no longer involved in chip removing. The feeding hole of the shredder is equipped with an additional feeding hopper. The feeding hopper is installed facing its opening towards the O.D. deburring units and the chip flow where the operator has no access. The feeding hopper can be equipped with a safety shutter which can be opened or closed by hand. The purpose of this unit is to avoid contact between the operator and the cutting blades during tool change at the O.D. deburring units. The shutter is also available in a aircontrolled modification. For better access during the O.D. deburring tool change the weld seam shredder can be mounted on guiding rails to make it possible to move it sideways or backwards. Also a Belt conveyor is possible Our cutting inserts have two cutting edges. Each edge can be reground up to 10 times. One cutting egde should last approximately 350 hours of operation. 15
