Application

This machine is suitable for unbalance correction of rotating workpieces like various marine crankshafts and multi-cylinder crankshafts.

Feature

This machine adopts Jianping’s electronic measurement system, with various measurement methods, dynamic and static balancing, bearing modes are up to 10 kinds, weight addition& removal, CW and CCW rotation can be flexibly customized. It adopts multiple calibration coefficient combinations, automatically adjusts system sensitivity, and shifts without jumps, software and hardware dual filtering, data compression, the measurement is more stable.

Applicable to medium workpieces
