Desk top budget roundness and cylindricity system with very high specification. Simple computer aided centring set-up allows rapid and accurate results. Table dia. 360mm with load capacity 20kg. accuarcy of rotation (0.04um+0.0006h)  Measuring dia. max. capacity 450mm.

All Roncorders of rotary table type have the unique Kosaka porous bearing spindle for extreme accuracy without  inner airflow  turbulance and vibration. 

Heavy duty rotary spindle  instruments with outstanding  features and max. capacity. A fully automatic cylindricity measuring instruments without equal. All centring, levelling and measuring functions are PC. controlled. The heavy duty precision workstage size  600 x 460mm  has a  travel of 1000mm in X and 100mm in Y and the vertical measuring capacity up to 760mm with a 200kg load. 

This is the ultimate  Roundness analyser for very large components such as engine block  inspection, cylinder head, crankshafts or heavy duty turbine shafts. Programme macros  can easily be set up to automatically measure multiple features such as cylinder bore, crankshaft pins and bearings for roundness, cylindricity, squareness and straightness profiles.

Installations include car manufacturing plants worldwide,  user list on request.

Heavy duty rotary table instruments with many outstanding features. The EC 3400 is a fully automatic cylindricity measuring instrument without equal providing  the highest accuracy of measuement of an instrument of this type..

The unit has outstanding combined accuracy of roundness, straightness, and parallelism between its rotational axis and vertical and horizontal datum straighness movement.

All centring, levelling and measuring functions are, if required,  automatically controlled with full measuring cycles making quick analysis even possible for complex parts.

The EC3200 is a fully automatic piston form measuring machine developed within the industry to meet the stringent criteria of piston design.

Accepted by many as the world standard for a machine of this type.

A floor standing Economy model with fully automatic functions to measure roundness and cylindricity of larger components.

Incorporates the porous bearing spindle and an extremely accurate vertical column.

Inner and outer profiles may be measured in the same cycle.

The EC-2500 Rondcorder's specification, capacity and design features make it unbeatable value for money..

Kosaka Roncorder Instruments includes  the  EC-3600 series designed to measure long shafts. The unit has 1400mm vertical traverse and a table loading capacity of 250kg. Component diameters up to 650mm can be accomodated on the rotary air bearing table. 

High  accuracies of table rotation and straightness in the vertical column ensure highly efficient measurements of pin, jornal and large crankshafts for roundness, straightness and cylindricity.
