YD256G multifunctional roundness measuring instrument Introduction: The YD256G multifunctional roundness measuring instrument is a rotary table universal roundness measuring instrument based on a precision air bearing spindle and using a computer measurement system. It is mainly used for measuring the roundness, waviness, coaxiality, concentricity, perpendicularity, parallelism and other parameters of rotating workpieces such as circular rings and cylinders. It is widely used in precision machinery manufacturing enterprises such as automotive parts, bearings, spinning machines, oil pumps and nozzles, aerospace, as well as colleges, research institutes, metrology institutions, etc. The instrument mainly consists of a high-precision air bearing spindle, a precision leveling and centering worktable, a granite tabletop, an electric granite column, a high-precision inductance measuring head, a precision rotary encoder, a drive control electrical box, a high-precision measurement electrical box, an air filtration and drying system, and a dedicated measurement and analysis software based on Windows XP. characteristic: 1. The spindle adopts an ultra high precision air floating shaft, which gives the instrument the advantages of high rotational accuracy, good stability, strong load-bearing capacity, non-contact, non wear, and long service life, meeting the national first-class precision standard. 2. The workbench and columns are made of natural granite material, which makes the mechanical performance of the instrument more stable, reliable, deformation free, drift free, and aesthetically pleasing. 3. Two levels of built-in air filters, a protective pressure relay, and an oil-water separator device ensure stable, clean, and dry working pressure of compressed air, ensuring good rotational stability and high accuracy of the air flotation spindle. 4. The spindle motor adopts high-precision speed regulation motor to ensure smooth and reliable rotation of the instrument spindle 5. The vertical and horizontal movements of the sensor are driven by linear motors, making the instrument easy to operate and adjust accurately. 6. Adopt a high-precision rotary encoder with 2048 lines per week to ensure data sampling resolution. The inductance signal measurement circuit of the instrument is a high-precision LVDT dedicated circuit independently developed by our company, with measurement accuracy and stability at the leading level in China. 8. The specialized measurement analysis management software based on the Windows XP operating system has functions such as automatic acquisition, automatic correction of eccentricity, instrument calibration, digital filtering, evaluation of measurement parameters that comply with the latest ISO standards, archiving of measurement result databases, and printing and outputting Technical parameters: Measurement items: roundness, waviness, concentricity, coaxiality, parallelism, flatness, perpendicularity, eccentricity Jump volume Spindle accuracy: ± 0.025 µ m System accuracy: ≤ [0.05+0.0005H] µ m Spindle speed: 2-6r/min (adjustable) Maximum load of turntable: 40kg Effective diameter of turntable: 256mm Minimum measured inner diameter: 3mm Maximum measurement height: 450mm Distance between spindle center and column: 260mm Rotating worktable: precise leveling and centering Sensor movement: Electric control of joystick Range: ± 50 µ m ± 100 µ m ±400µm Measurement resolution: 0.01 µ m Maximum sampling resolution: 8192 points per week Digital filtering file: 2-15、2-50、2-150、2-500、
