Features
RONDCOM NEX
Roundness & Cylindrical Profile Measuring Instruments
A 3-in-1 Machine Satisfying Various Measurement Needs with Functions to Measure Roundness, Diameter, and Roughness, as well as Selectable Specifications
In addition to roundness measurement, RONDCOM NEX offers high-precision diameter measurement with functions common to the series. The NEX Rs/Rs α models are also capable of measuring roughness. Users can choose from various specifications to suit their needs, such as a higher maximum loading mass (30/60 kg), greater column size (300/500/900 mm), and either manual or automatic alignment and detector orientation adjustment.
Labor-saving option: AFD(Automatic Force adjustment Detector)
The AFD (Automatic Force adjustment Detector) allows automatic adjustment of measurement direction and force in the software. As such, it is possible to automatically measure the outer and inner diameters of a workpiece. When measuring notched workpieces, the front travel can be automatically adjusted to prevent the stylus from dropping.
Dramatically Improving Efficiency of Measurement of multiple workpieces and multiple locations Labor-saving option: XY-Axis Automatic Stage
When measuring a large number of workpieces, a typical table rotation roundness and cylindrical profile measuring instrument requires the workpiece to be replaced multiple times between individual measurements. However, the RONDCOM NEX series features a common optional XY-Axis Automatic Stage, allowing many workpieces on the stage to be measured at once without requiring any special setup. This is a labor-saving option that minimizes operator effort and reduces measurement take time.

Versatility
Wide-ranging lineup and accessories enabling measurement of various types of workpieces
Offset detector holder enabling measurement of thick workpieces with no interference
Standard accessory for RONDCOM NEX 100/200
Manual type
Outer (inner) diameter and upper (lower) surface measurement can be switched over simply by bringing down the holder (Patented)
If this offset-type detector holder is brought down, the detector naturally changes its orientation by 90 degrees, thus not requiringmanual rotation of the detector.
Standard accessory for RONDCOM NEX 300
CNC type
Changes detector posture automatically with software or CNC program
Offset-type CNC detector holder has excellent features of the conventional offset-type detector holder and also can automatically change the posture of the detector. It can automatically control the posture of the detector for inner/outer diameter, or upper/lower or tapered surface, significantly increasing measurement efficiency.
Multifunctional
Diverse measurement functions that go beyond the conventional roundness/cylindrical profile measuring instruments
Measurement of inner and outer diameters with high repeatability
Opposed Diameter Measurement Function (Patented)
To measure the diameter of a workpiece with a general roundness/cylindrical prole measuring instrument, measurement is taken by applying the stylus to the workpiece from one side and the radius value thus obtained is doubled to determine the diameter. However, if a deviation occurs in the relative positions of the measuring machine and the workpiece due to temperature changes, the deviation is reected on the diameter value. Accordingly, it is impossible to perform measurement with high repeatability, even if a highly accurate scale is mounted. In opposing diameter measurement funtion, which is a standard feature of RONDCOM NEX series, a workpiece is measured at the 0 degree and opposing 180 degree positions of the table, respectively. The evaluation algorithm implemented as thestandard to correct the errors by temperature change and generatrix line shifting, performs highly-precise diameter measurement.
Measurable diameter
- With standard holder : φ 30 mm or less
- With opposed diameter measuring holder(optional) : φ 100 mm or less
Labor Saving
Excellent labor-saving options reducing operator interventions to achieve higher efficiency in measurement
AFD (Automatic force adjustment detector) enabling automatic switching of roundness and surface texture measurement, and roundness and diameter measurement
The previous detector required manual adjustment of measuring directions, measuring Forces and front/over travel by using front knob, but the AFD enables automatic adjustment of these on the software.
Automatic adjustment of front travel
Capable of measuring multiple locations and workpieces without setup change XY-Axis Automatic Stage (Patented)
Continuous measurement of multiple workpieces / locations with no changeover.
Can be freely attached, removed, and capable of being retrofitted
Since it can be attached and removed by customer, customer can choose between the standard table and the XY-axis automatic stage depending on the workpiece.As this option is available for retrofitting, it can be attached to an existing machine.
Usability
User-friendly design common to the series, minimizing the operator’s workload to achieve stress-free operation
New operation panel with clear and intuitive icons and safety feature
Excellent operability is achieved by icons clearly indicating the operations to execute. In addition, “override dial” controlling the driving speed of R-axis and Z-axis in real- time and “lock button” invalidating panel operations other than measurement stop, emergency stop and release of emergency stop enhance safety in measurement.
Override Dial: Turning the override dial in the initial execution of the CNC program or measurement of narrow spaces temporarily reduces the speed so that measurement can be performed safely while the operator is checking the operation.
Lock Button: Pressing the lock button prevents accidents caused by accidental misoperation such as unintended operation of the machine resulting from the body or the workpiece hitting the joystick in setting.
DX type designed for comfortable operation and small footprint
The measurement section of the DX models of RONCOM NEX series is integrated with anti-vibration table and data processing section. This saves the footprint and enables the operator to perform all operations comfortably in front of the measurement section without the need to move between the sections, such as standing in front of the measurement section to adjust the measuring position while looking at the workpiece and in front of the data processing section to operate the software while watching the screen.
Integrated measurement analysis software ACCTee enabling all operations to be performed intuitively
ACCTee is a software that makes it possible to perform the whole inspection process consisting of preparations, such as calibration and alignment, measurement, analysis and printing of result in an extremely intuitive manner. With this software, a CNC program for automatic execution of alignment, measurement and output of result can be created easily. Measurement values and 3D color maps can be freely arranged on the measurement result sheet, which can be printed or converted to a PDF file and used as an inspection report.
Automatic oiling mechanism making it sufficient to supply oil to the column once a year.
An oil tank and an automatic oiling mechanism are built into the Z-axis column. While a general roundness cylindrical profile measuring machine requires periodic oiling of the column, no manual oiling is necessary for RONDCOM NEX as the internal mechanism of the column is automatically oiled. All the operator needs to do is to fill the built-in oil tank once a year.
Stainless steel rotary table that makes oiling and use of anti-corrosion paper unnecessary
The rotary table of RONDCOM NEX is made of stainless steel. It can be used effortlessly with no daily maintenance such as oiling and covering with anti-corrosion paper after use.
Ceramic R-axis arm requiring no daily oiling and hardly affected by temperature changes
The R-axis arm, which is made of ceramic, is low-maintenance as it does not require daily oiling to prevent corrosion. Also, because of its low thermal expansion coefficient, the impact of room temperature changes on the accuracy can be minimized.
