About This Product

The SB-7705R series is a field balancer for elastic rotors that uses a multi-speed/multi-plane method to suppress high-order bending mode unbalanced vibrations that occur in high-speed spindles. This is the only product in the industry that has succeeded in suppressing 3-dimensional (XYZ directions) vibration in the entire operating rotation range.

■Applications

・High-speed rotating machinery that accelerates and decelerates, such as machining centers, textile machines, and high-speed tapping centers. ・All rotating machinery such as NC lathes, high-speed mold processing machines, high-speed slicers, dicing saws, internal grinders, woodworking machines, crushers, blowers, pumps, and compressors. - Grinding machines (surface grinding machine, forming grinding machine, centerless grinding machine, cylindrical grinding machine) can also be modified with options. Main features

■Possible to correct balance of elasticity/rigidity rotor

・As the main shafts of high-speed rotating machines have become faster and more compact, their bending rigidity has relatively decreased, and they now have critical speeds in their operating ranges. ・The balance correction using the multi-speed/multi-plane method that the SB-7705R series is equipped with can be corrected over the entire rotation range from low speed to ultra-high speed.

■Correction result prediction function

Efficient balancing is possible by predicting correction results.

■Equipped with FFT analyzer as standard

Includes basic frequency analysis and bearing diagnostic functions

■Vibration analysis function

・Unbalanced vibration analysis ・Harmonic vibration analysis ・Overall vibration monitor

■Lissajous curve display function

・Lissajous for each rotation speed can be displayed continuously. ・Visually check the trajectory of the axis

■Easy to create reports and manage measurement data

・Can be managed using registered names for each measurement data ・Measurement data can be transferred to a PC via USB communication ・Measurement data can be saved to USB memory ・Hard copy of the screen is possible

■Supports balance correction method using opening angle calculation (optional)

In addition to correcting the balance of grinding wheels, by installing a balance piece mechanism in general rotating machinery, it is possible to correct the balance without having to make correction weights on site. (Supports G:1 side / GW:2 side correction)

■Main options

・Vibration channel option ・Opening angle calculation balance (grinding wheel balance correction, etc.) ・Multi-surface measurement vibration sensor + cable
