Marble Tilt Pendulum (also known as Granite Tilt Pendulum, Granite Tilt Pendulum Checker) Usage: Mainly used for measuring shafts, plate-type products, and their components, primarily detecting radial runout, ellipticity, and face precision error.
Advantages:
1.花岗石基座 adoption enhances the accuracy of the datum plane, reducing the precision error of the pendulum instrument itself.
2. The activity table mount can be measured at any position on the instrument mount.
3. Rust-free instrument stand, easy to use and store.
Main Technical Parameters:
Radial rotation accuracy: 0.001mm
2. Parallelism of side guide rail over full length for both: 0.005mm (A03 model), 0.008mm (A05 model), 0.01mm (A10 model)
3. Precision Error: Less than 2um for 300mm, less than 3um for 500mm, less than 5um for 1000mm, less than 6um for 1500mm.
4. Tested Parts - Large Diameter 340mm, Large Lengths 300mm, 500mm, 1000mm, 1500mm
Marble (Granite) Bias Gauge Measurement Steps:
1. Measurement of radial circular跳动
⑴ Clean the part, tighten the eccentric shaft bolt, and place it between the eccentric pendulum (the part with holes should be mounted on the center shaft), allowing the part to rotate freely without axial movement. Then, securely fasten the two bases. When removing the part, support it with one hand and press the handle L downwards with the other to remove the part.
⑵ Mount the dial indicator on the stand, aligning the indicator stem with the part's axis line, approximately perpendicular to it. Place the probe in contact with the part's surface, compress it by about 1 to 2 turns, and then securely tighten the stand.
⑶ Rotate the measured part one full turn and record the maximum and minimum readings on the dial indicator. The difference between the maximum and minimum readings is the radial roundness error value at the I-I section.
⑷Measurements should be taken on three cross-sections along the axis (as shown), and the largest circular runout error among the three cross-sections is taken as the radial circular runout error for the part.
2. Measurement of End Face Roundness:
(1) Clamp the lever dial gauge on the gauge stand of the eccentricity check instrument, slowly move the stand to make the measuring head of the lever dial gauge touch the measured end face, and press the 0.4mm rod into its correct position.
⑵ Transfer
Record the maximum and minimum readings on the dial indicator during one revolution of the moving workpiece. The difference between these two values is the face runout error at the diameter.
⑶ Measure at three evenly distributed diameters on the tested face, and take the largest value among the three as the circular跳动error of the part face.
Operation Procedure for Marble Tiltmeter
The marble inclinometer is a precision testing instrument. Operators must be proficient in the instrument's operation, meticulously maintain and care for it, and assign a designated person to use it.
2. Marble Inclination Gauge Maintain the equipment in good condition at all times. The equipment installation should be balanced and reliable, with the guide rail surface being smooth and free from dents or scratches. Additionally, the coaxiality tolerance should be less than 0.02mm in both the a and b directions within the range of L=400MM.
3. Before workpiece inspection, the precision of the pendulum gauge should be verified using a 400MM long test bar and a micrometer, and it can only be used after ensuring it meets the required standards.
During part inspection, handle with care and avoid placing any tools or parts on the guide rail surface.
After the workpiece inspection is completed, the instrument should be immediately maintained and serviced. The guide rails and sleeves should be oiled to prevent rust, and the surrounding environment should be kept clean.
Three, a designated person shall conduct precise measurement checks on the pendulum instrument at the end of each month to ensure the equipment is in good condition and maintain records of the actual measurements.
