A higher operating pressure, however, means special requirements for the installation and the control dynamic of the cutting head drive, says Resato International from Roden, which introduced the linear drive for the waterjet cutting at the end of 2006. Using the direct linear engines ensures that the cutting head positions with an accuracy of approx. 10 μm, while a repeatability of 15 μm is attainable. These values are better than those obtained with mechanical drives with, for example, ball-bearing by-pass spindles, where there is always some (revolution) play.

With the direct linear drive, therefore, more narrow tolerances can be handled in dimensions, parallelism and square angles. The cutting process can be interrupted without any problem, because the cutting head will return to exactly the previous position.

The no-contact linear drive is not subject to wear and tear and therefore maintenance-free. Higher cutting speeds can also be applied without any problem. So, with the new 6,000 bar Powerjet pump, Resato is further expanding the advantages of the direct linear drive. Not only can cutting be done one and a half times as fast as with a 4,000 bar pump, but proportionately less abrasive and water is used. These advantages translate into higher productivity and lower production costs.
