Fully Computer controlled processing www.micro-technica.com • Used on new Dies, to refi ne EDM fi nish, and used Dies, to repolish • Repeatable quality • Attains surface fi nishes below 5 micro-inch (0.12 micrometre) Ra • Can be used on solid and hollow-chamber Dies • Signifi cant savings in time • Fast „Return of Investment“ (ROI) • Fast and easy to operate • Gives surface fi nish in same direction as material fl ow through Dies Micro Stream® for Aluminium Unparalleled capabilities for extrusion performance and Die makers by fully automated Die polishing „Automated Die Polishing System“ The Picture by WEFA

Fully computer controlled processing All Micro Stream® machines provide clamping and sealing of the Dies plus the ability to fl ow a preselected volume of a preset number of cycles. Please note the upper and lower media cylinders. Abrasive media is pumped from the lower media cylinder through the Die into the upper cylinder. Between the lower Cylinder and the Die we have an AFM-Media Heat- and Cooling system (automatically). This guarantees repeatable surface speed and longer Media life. Flow is then reversed and media is pumped back through the Die into the lower cylinder. This is defi ned...

tooling restrictors are sometimes needed for uniform polishing to take place. Fixtures are made from a variety of materials. Aluminium and plastics, such as structural nylon, are used to reduce fi xture weight. To properly apply Abrasive Flow Technologies to Extrusion Die Polishing, the ”fi rst law of AFM” should be stated: “Adrading is greatest where media velocity is highest.“ STREAMER© (AFM-Medium) The STREAMER® is the third basic element of Micro Stream®. The polymer-based abrasive laden media is the cutting tool of abrasive fl ow machining, and works by mechanical abrading, i.e. by...

Customer testimonials: • “Repolishing time for all Extrusion Dies has been reduced drastically. The average time for repolishing is now between 1-3 minutes in the machine, plus some time allowance for handling and cleaning.“ • “All surfaces, corners and slots are polished uniformly which give uniform surface speeds during the Extrusion Process.“ • “Improved surface fi nish on the Extrusion itself. Interestingly enough this improvement does not show itself until Dies have been abrasive fl ow machined several times, showing that the repeated uniform processing pays dividends in quality of...
