Japanese Sanfeng RA-2200AS/AH series rotary worktable

Japanese Sanfeng RA-2200AS/AH series rotary worktable：

The Japanese Sanfeng RA-2200AS/AH series is not simply a rotating worktable, but a high-precision roundness and cylindrical shape measuring instrument integrated with the worktable,
As the core component, its rotating worktable is equipped with precision drive structures such as X-axis and Z-axis, and features automatic centering and leveling, micrometer level measurement accuracy, etc,
Widely used in the detection of form and position tolerances in automotive components, precision bearings, aerospace components, and other fields. The following provides a comprehensive analysis of its technical parameters and performance advantages in terms of core components, functional extensions, and auxiliary parameters:

1. Core rotating worktable parameters:
The accuracy of this series of rotating workbenches is the core competitiveness, with a radial rotation accuracy of (0.02+3.5H/10000) μ m and an axial rotation accuracy of (0.02+3.5X/10000) μ m,
Among them, H represents the measurement height, X represents the measurement radius, which ensures high-precision measurement of roundness, cylindricity, and flatness. The effective diameter of the workbench is 235mm,
The workpiece can carry a weight of 30kg and is suitable for most small and medium-sized precision workpiece inspections. The workpiece diameter can reach 580mm, and the measured diameter is 300mm, with strong compatibility.
The speed is adjustable in four levels: 2, 4, 6, and 10 rpm, which can be flexibly switched according to the workpiece material and measurement requirements.
As the core highlight, the A.A.T automatic centering/leveling system has a centering amplitude of ± 3mm and a leveling range of ± 1 °. It can automatically complete centering and leveling after predicting two cross-sections, greatly reducing measurement preparation time.

2. Key axis motion parameters:
The core difference between the two models is concentrated in the Z-axis stroke. The Z-axis stroke of RA-2200AS is 300mm, while that of RA-2200AH is increased to 500mm,
Adapt to the measurement requirements of workpieces at different heights. The Z-axis straightness (λ c2.5) is 0.15 μ m/300mm and 0.25 μ m/500mm, respectively, and the parallelism with the turntable axis corresponds to 0.7 μ m/300mm and 1.2 μ m/500mm, respectively,
And the positioning speed can reach 50mm/s, with measurement speed adjustable in four levels: 0.5, 1, 2, and 5mm/s. The horizontal arm (X-axis) has a horizontal movement stroke of 175mm, including a protrusion from the rotation center of -25mm to+150mm,
Its straightness is 0.7 μ m/150mm, and its perpendicularity to the turntable axis is 1.0 μ m/150mm. The positioning speed controlled by the joystick is 30mm/s, and the measurement speed is consistent with the Z-axis. Combined with grating ruler positioning technology, it ensures the accuracy of movement and measurement.

3. Needle and detector parameters:
The measuring range of the needle system covers multiple levels of ± 400 μ m, ± 40 μ m, and ± 4 μ m, meeting the detection requirements of different precision levels.
The force measurement supports a 5-level conversion of 10-50mN, which can avoid damage to the surface of soft material workpieces. The standard configuration is a 1.6mm hard alloy ball measuring needle,
The measuring needle angle can be adjusted with a scale within a range of ± 45 °, suitable for measuring the contour of workpieces at different tilt angles. The detector bracket is equipped with a sliding mechanism with a stroke of 112mm,
It can continuously measure the inner and outer diameters (inner diameter measurement can reach 50mm) without changing the direction of the detector, making it easy to operate for complex workpieces such as deep holes and thick walls. In addition, an optional roughness detector can be installed to expand the roughness measurement function in the circumferential and axial reciprocating directions.

4. Auxiliary and adaptation parameters of the whole machine:
The whole machine is powered by a 100V-240V AC power supply, compatible with 50/60Hz frequency, and requires a gas source pressure of 0.39MPa,
Gas consumption is 30L/min. In terms of external dimensions, the RA-2200AS measures 940 × 510 × 900mm and weighs 180kg; the RA-2200AH has increased Z-axis travel,
The height has increased to 1100mm and the weight has reached 200kg. The equipment is also equipped with multiple safety measures, and the detector has Z-axis collision detection function when the vertical posture is detected. When the displacement exceeds the range, it will automatically stop and prompt an error,
Effectively protect core components from damage. Paired with RONDPAK professional software, advanced functions such as power spectrum analysis and spiral measurement can be achieved, making the analysis and output of measurement data more professional.
