About This Product

■Product overview

Maintenance-free, high reliability, excellent measurement data reproducibility, and low noise ensure measurement accuracy. Can be installed in any location. High-speed rotational displacement meter (RVA tester Model THD3616) Shipping started in 2009 THD3616 RRVA tester measures displacement, speed, acceleration, disk thickness, TIR, PDDR of aluminum and glass substrates for magnetic disks from 3,600 to 16,000 rpm. It is now possible to measure the dynamic characteristics of -Disk size can be selected from 1.3", 1.8", 2.5", 3.3", 3.5", and 5.25". (1.3",1.8" are optional) - The rotational speed of the disc is automatically set and precisely controlled by an automatic tracking mechanism. ・The accuracy of the reference disk/hub surface is less than 0.1μm, and the operation is simple.

■Features

・Since the beginning of development, we have adopted a specially designed ultra-precision spindle motor and a resonance-free design that can ignore vibrations from the ground. The THD3616 has inherited this philosophy, so it can be installed anywhere. ・The noise during measurement is very small, ensuring the accuracy of the measurement data. - Data measured by a stable and robust mechanism has excellent reproducibility. If you remove the disk after measurement, reinstall it and measure, you will get the same data. Additionally, the correlation coefficient of data between already delivered devices is 0.99, close to 1, giving us a high reputation and trust. ・As the name suggests, this RVA tester uses dynamic measurement to measure Run-out, Velocity, Acceleration, and PDDR at the same rotation speed as the hard disk unit, so you can obtain data that matches the actual situation.

■Probe one positioning method

・Feeding method: Precision ball feeding mechanism ・Movement guide: Double linear guide mechanism ・Drive method: Automatic feed by AC servo motor ・Drive method: Automatic feed by AC servo motor and manual operation possible ・Stroke: 74.25 mm ・Probe spacing adjustment: Manual adjustment using a micrometer, automatic adjustment mechanism (optional)
