Buyer’s Guide 2012 Update: Testing and Quality Control CMM offers scanning, optical measuring capabilities for inspection of small parts

| Redakteur: Kathrin Schäfer

The O-Inspect 322 coordinate measuring machine (CMM), the smallest O-Inspect system available from Carl Zeiss IMT, expands the application range of the company’s CMMs. The system unites contact, Zeiss scanning and optical measuring, as in the larger O-Inspect 442.

“Small yet large’, as the manufacturer says, the O-Inspect coordinate measuring machine, the smallest CMM Carl Zeiss offers, brings multiple measuring technologies to bear in the inspection of smaller parts.

Both machines use the same sensors and have the same functionality. The difference between them is their measuring range. With a measuring envelope of 300 x 200 x 200 mm, the more economical O-Inspect 322 is suited for inspection of relatively small parts. This CMM is priced competitively with systems that have exclusively optical measuring technology, despite coming as standard with contact sensors and Zeiss scanning.

The optical and contact sensors of the O-Inspect 322 are built in, and easy-to-use Calypso 3D CAD software merges the measured data.

3D measurements with minimal probing forces

Whereas other machines can offer only single-point scanning, and thus relatively high probing forces, the O-Inspect 322 provides scanning as a standard feature: the Vast XXT probe enables precision probing with forces in the millinewton range. Therefore, true 3D measurements that allow form and position statements are possible.

Because telecentric optics are very elaborate, they are not used on most optical measuring machines. The O-Inspect 322 comes with a 12X telecentric zoom lens from Carl Zeiss Microscopy, which compensates for distance deviations with an additional zoom range.

Precision in any environment

The CMM works reliably under varying ambient temperatures. Whereas other CMMs must operate in climate-controlled measuring labs, the O-Inspect delivers reliable results over a wide range of temperatures and can even be deployed on the shop floor. The machine thus is ideal for locations presenting difficult environmental conditions.
