WEFOUNDA System for Cutting Ladies Garments: A Complete and Reliable Guide for Dress Makers; Instructions for Its Use (Classic Reprint)


What impressed you most abouht the Exact PipeCut 280E?

All aluminium pipes that arrived onsite still had to be cut down to size. Because chop saws only cut up to 140mm pipes, the rest were being cut with and angle grinder. This is not accurate or easy with all the fuss of getting the ends straight, it would take about and hour to cut 3 pipes. The time it takes to cut 3 pipes with the PipeCut 280E was 1 minute 30 seconds! In my opinion, every site should have an Exact Tools pipe-cutter.

Firstly, the quality and the speed means we save huge amounts of time (and money). Secondly, the straight cut we get means we are able to face the ends and get the perfect angle with which to get the clutch for connecting the two ends.

It was a big surprise when we discovered that you could cut the pipe even without anything to guide you. You had to practice a couple of times to get the feel, but then it was easy. I think this shows how good the design of the machine is when it can do something like this!

In 1965, the first production laser cutting machine was used to drill holes in diamond dies . This machine was made by the Western Electric Engineering Research Center . [2] In 1967, the British pioneered laser-assisted oxygen jet cutting for metals. [3] In the early 1970s, this technology was put into production to cut titanium for aerospace applications. At the same time CO 2 lasers were adapted to cut non-metals, such as textiles , because, at the time, CO 2 lasers were not powerful enough to overcome the thermal conductivity of metals. [4]

The parallel rays of coherent light from the laser source often fall in the range between 0.06–0.08 inches (1.5–2.0 mm) in diameter. This beam is normally focused and intensified by a lens or a mirror to a very small spot of about 0.001 inches (0.025 mm) to create a very intense laser beam. In order to achieve the smoothest possible finish during contour cutting, the direction of beam polarization must be rotated as it goes around the periphery of a contoured workpiece. For sheet metal cutting, the focal length is usually 1.5–3 inches (38–76 mm). [6]

Advantages of laser cutting over mechanical cutting include easier workholding and reduced contamination of workpiece (since there is no cutting edge which can become contaminated by the material or contaminate the material). Precision may be better, since the laser beam does not wear during the process. There is also a reduced chance of warping the material that is being cut, as laser systems have a small heat-affected zone . Some materials are also very difficult or impossible to cut by more traditional means.
