ACM 2015 Waterjet Cutting Machines

The cutting table comprises a precision-built steel construction embodying linear direct-drive motors on each of the two main axes. To achieve the required precision, the bridge and self-propelled carriage plate are powered by two direct-drive linear motors on each side. This results in a speed range from 1 to 30.000 mm/min. 

Use of these components and construction enables the installation to achieve positioning accuracy and repetition accuracy of ± 50µm (at 20 °C) across the machine's full range. The guideways and drives are suitably protected from water and abrasive through bellows and protective stainless steel plating.

Direct-drive linear motors guarantee:

• Better cutting behavior and absolute repetition accuracy (without needing to back-up) of the cutting head compared to traditional mechanical transitions using spindle, pinion, rack and gears

• Low maintenance as a result of the non-contact principle, combined with greatly reduced wear parts consumption

• Wide range of cutting speed and jogging speed, adjustable from very low to very high

• Fast response enables cutting speed to be rapidly changed
