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

 

Unmanned Production

Due to automatic control of the PJ high pressure pump and the process parameters, permanent supervision during the cutting process is not required. Resato water jets are equipped with an automated stop function that trips once a cutting task is completed. This means that all units will be acting in standby mode or will shut down and almost no energy is required.
