RONDCOM 76A
The flagship model of the detector-rotating type instruments that boasts the world’s best quick, high precision measurement of large workpieces or heavy workpieces.
Features
Measuring large workpieces or heavy workpieces in a short time
In the standard specification, this device possesses a stroke of 1000 mm in the vertical direction and 700 mm (± 350 mm) in the horizontal direction, and it can handle a maximum payload of 400 kg. Furthermore, it can also expand the maximum payload (1 ton, a stroke of 1,500 mm in the horizontal direction) or expand the stroke in the vertical direction (1,500 mm). The device can measure large or heavy workpieces such as automobile engine parts or heavy duty equipment that are difficult to measure with common rotary table type roundness and cylindrical profile measuring instruments. In addition, as the device drives each axis at an extremely high maximum speed of 100 mm/s, it can quickly approach the measurement point, so that it can measure even large workpieces in a short time.
High precision in the world’s highest class as a detector- rotating type roundness and cylindrical profile measuring instrument
Tokyo Seimitsu has gathered technology cultivated over many years, so despite being a large device of the detector-rotating type, it realizes radial direction rotation accuracy of (0.04+3H/10000) µm.
A high precision air bearing is employed on the θ-axis / a guide mechanism supports the X-axis, Y-axis, and Z-axis with an air bearing
Wear does not occur on the guide surface, and it displays high rotation precision and straightness precision over a long period
Gabbro is employed in the base column
This has changed little over time and maintains stable precision over a long period
A pneumatic anti-vibration table is installed as standard
This reduces the transmission of vibrations from the floor, and prevents impacts on the precision
A variety of evaluations
Measurements that can be performed with RONDCOM 76A, are not only the measurements of the workpiece inner and outer diameter roundness and cylindricity, coaxiality and straightness in the Z direction. The straightness is guaranteed for all of the table’s X-axis and Y-axis, and the R-axis of the detector retention part, and due to the guarantee of straightness precision of the X-axis and the Y-axis, the evaluation of parallelism in the linear direction and the evaluation of the flatness of the upper surface of the workpiece, through the guaranteed straightness of the R-axis, can be performed. For example, for a workpiece in which several bores of the same shape, such as cylinder blocks, are lined up, it is possible to evaluate the parallelism between the bores. In addition, we provide numerous accessories to extend the measurement range, such as a long axis measuring tool and thin detector suitable for measuring crankshafts, to measure deep inside a hole.
