Latest Optical Technology Enables High-Precision Measurements

Measuring Systems – The Guarantee for Maximum Precision

KEYENCE XM-1200 – An image-guided 3D coordinate measuring device with infrared transmission, combined with the latest optical technology, enables high-precision measurements. The component to be measured can be compared and evaluated with its CAD data, both in terms of dimensional measurements and form and positional tolerances.

  • Measuring range: 600 x 300 x 200 mm
  • Maximum object table load: 25 kg
  • Measurement accuracy: 8 μm
  • Repeatability: 3 μm

SURFCOM FLEX – With the 3D profilometer SURFCOM FLEX from ZEISS, simple and precise surface measuring tasks can be performed quickly. The equipment provides, among other things, very high accuracy, reproducibility, and very high measuring speeds (additional feed unit with patented linear motor technology and glass scale in the X-axis).

There are Five Levels of Cut Quality in Waterjet Cutting Dimensional

Accuracy in Waterjet Cutting

In waterjet cutting, there are five levels of cut quality, which primarily depend on the cutting speed and the amount of abrasive used.

Quality Cut —> Rough Cut

  • Q1 – Dimensional accuracy +/- 0.05 mm at the top edge of the part, cut bevel approx. 0.1 mm, about 80% smooth portion?
  • Q2 – Dimensional accuracy +/- 0.1 mm at the top edge of the part, cut bevel approx. 0.2 mm, about 50% smooth portion?
  • Q3 – Dimensional accuracy +/- 0.1 mm at the top edge of the part, cut bevel approx. 0.3 mm, about 30% smooth portion?
  • Q4 – Dimensional accuracy +/- 0.1 mm at the top edge of the part, cut bevel approx. 0.4 mm, about 20% smooth portion?
  • Q5 – Dimensional accuracy +/- 0.1 mm at the top edge of the part, cut bevel approx. 0.5 mm, about 10% smooth portion?

There can be up to a 100% difference in speed between Q1 and Q5. This factor makes it difficult to compare quotes.
