Increasing tool life using cooling

BY using improved MMKS-systems, high additive lubricants, cooling-nozzles, blades with specially adapted cutting geometrics and modern machines, it is now possible to achieve 50,000 pieces of steel and 30,000 pieces of stainless steel compared to former tool lives, Sat Semer Anlagen- Technik claims. This increase is possible by improvement and higher precisions of the machines, higher feed, the use of high-performance lubricant and the use of cooling-nozzles. One case study using a fully automatic sawing-machine – the MMKS-system SAT P-202 – a SETOL high-performance lubricant and cooling-nozzle, achieved the following results: • High-tensile steel S460MC with a tensile strength of 670N/mm² • Tube 30x2x1,700mm • Tool life ca. 6,000 by 1,027 per hour

• The 100% lubrication and cooling provide a performance increase of stress on the tooth up to > 0.12mm/tooth. 100% lubrication results in steel tube 40x1.5mm at 50,000 cuts consumption uses only 400ml SETOL high-performance lubricant. The combination of MMKS with high- additive lubricants and cooling-nozzles is used serially for HM-sawing-blades with diameter up to 1,600mm. The company says the use of MMKS- systems and the high-performance lubricants results in: • Increase in tool life • High cutting performance • Less burr cuts • Non-ferrous heavy metal can be continued • Processing by using special lubricants (no degreasing before soldering is now required)

• Savings by reduction of washing process • The tubes can be brushed, measured and discharged into the carrier after cutting • Savings in removal of emulsion and cleaning cost for polluted workplaces and machine parts • Using non-water-miscible-oil the elixir water is preserved.

It also includes alarm messages and an electronic disk protection device for added security. The workpiece length is determined by a bar stop that can be positioned manually. The bar stop back feeding device and workpiece unloading are standard, and the workpiece discharging length is variable at the customer’s request.

Cutting line fitted with double rollers

A CUTTING line from Maco, Italy, features a tube feeding system made from two rollers provided with a device for the trim-cut – with adjustable dimension. With accelerating and decelerating ramps, the head cut-off length can be changed and memorised. A logic control system with a touch-screen user interface allows different programs to
