EC 1850
EC 1850 is a rotary table type roundness and cylindricity measurement system and has a automatic centering and tilting features that facilitate Fully Automatic Operation. Maximum measuring sample height is 470 mm for Outer Diameter and 320 mm for Inner Diameter. Rotational accuracy of this system is (0.04+0.0005H) μm where H is height from table (mm). The straightness accuracy of the vertical column is 0.4 μm/100mm and Parallelism of 0.5 μm/ 100 mm.

EC 2200
EC 2200 has an auto-centering and tilting features that makes this system is a Fully Automatic Operation. It also uses porous static pressure air bearing system. Maximum measuring sample height is 470 mm for Outer Diameter and 320 mm for Inner Diameter. Rotational accuracy of this system is (0.015+0.0004H) μm where H is height from table (mm).The straightness accuracy of the vertical column is 0.1 μm/100mm and Parallelism of 0.4 μm/ 200 mm.
EC 2500 / EC 2700
These two systems have supreme column accuracy and at the same time enable both inner and outer profiles to be measured in a fully automatic sequence (EC 2500 F and EC 2700F model). It also incorporates auto centering and tilting features for easy set up. These also have an options of long column which enable vertical motion range of 700 mm. Maximum measuring sample height is 570 mm for Outer Diameter and 420 mm for Inner Diameter. Rotational accuracy of this system is (0.02+0.0003H) μm where H is height from table (mm).The straightness accuracy of the vertical column is 0.05 μm/100mm and Parallelism of 0.5 μm/ 200 mm.
EC 1850 P / EC 3300 P
These two models are piston form measuring system. With those models, piston can be measured automatically with maximum accuracy and repeatability for size, ovality, taper, form, ring groove form, cylindricity, pin hole squareness, etc. With our system, Pistons without symmetrical form, correct centering and tilting can be achieved from design values. Rotational accuracy of this system is (0.02+0.0003H) μm where H is height from table (mm).The straightness accuracy of the vertical column is 0.5 μm/100mm.
EC 3600 series
EC 3600 model is a rotary table type models which is normally use for large diameter components (up to 700 mm diam.) or long components (up to 1420 maximum measuring height). There are 3 different models of EC 3600 depending on the sample diameter and length. Rotational accuracy of this system is (0.06+0.0006H) μm where H is height from table (mm).

EC 5100/EC 6100
These two models is the giant type automatic cylindricity measuring instruments with Rotary pick up type. The measuring space of EC 5100 is 600 x 460 x 1000 mm and 1300 x 830 x 2000 mm for EC 6100.
