OVERSEAS laser system manufacturers are perceived by local industry as the benchmark. Peter Bristow, director of Bristow Laser Systems (BLS), a Melbourne based company, does not subscribe to this theory.
"In fact our newest Elite series of high powered linear drive systems puts that perception to rest,” he says.
“The myth that because our systems are less expensive, the end user must suffer performance and specification inadequacies is just not the case," says Peter.
In a recent test by a large customer who was looking at two new laser systems, BLS and two other companies were short listed from an initial field of twelve suppliers.
All three companies supplied detailed system specifications, company profile, and cutting feedrates. Initial replies offered a wide range of cutting feedrates from systems with laser power levels from 4.4 - 5kW.
Differences in the data supplied, required a better solution for an accurate comparison between manufacturers advertised cutting feedrates. An independent test was established using a dxf cutting layout supplied to all three, to be cut in mild steel up to 16mm, stainless steel up to 6mm with plastic mask and up to 10mm no mask and aluminium 5005 and 5083 series up to 10mm.
All suppliers were to supply their best cycle times on this layout, these times would need to be reproduced at both supplier's and customers site by the successful supplier.
BLS supplied figures using its new Elite series, with a new PRC STS 5000 watt laser. The results were interesting.
BLS cycle times were faster in 7 out of the 8 materials, with up to 40 percent faster cycle times in both stainless steel and aluminium.
The figures collected from all three companies showed the irrelevance, of manufacturers stated feed and acceleration rates. What secured these orders was that the BLS Elite simply produced "more parts per hour", thus making the decision simple -- producing more parts produces more profit.
