AUTOMATIC ARMATURE BALANCING MACHINE
1. SALIENT FEATURES
1.1. Completely automatic operation. Operator simply has to place the jobs at the input station and remove them from the output station. The OK jobs and the OUT OF TOLERANCE jobs are separately stacked.
1.2. 4 cutters are provided at the correction station to simultaneously mill on LHS and RHS. This ensures fast correction.
1.3 Correction in 90o components is ideal for jobs having high initial unbalance as compared to polar corrections. Higher depth of milling means more unbalance can be corrected. Secondly, the 90o correction method means that second run balancing is possible.
1.4. Milling system does out to in milling ensuring that the stack is not damaged during milling due to flaring. It also means milling can be done at the ends which reduces the total unbalance correction required.
1.5. An automatic linear transfer system ensures minimum space for operator movement. A rotary transfer system is provided when space limitations are not there.
1.6. Zero clearance 'slides' and electronic depth measuring with resolution of 0.05mm helps achieve good correction ratio.

Innovations in balance measurement, corrections, transfer, and data collection systems greatly enhance machine performance. An example of this is Hines patented A.C.E. (Automatic Correction Enhancement). With ACE turned on, the computer monitors the initial and final unbalance, then makes adjustments to the correction routine. Just leave the machine running and performance is constantly optimized!
Excellent correction ratios were not enough for our customers. To make this exceptional performance easier to quantify, we developed an internal statistics package to monitor and analyze the balancing process. Turn the internal statistics package on and you will have continuous data collection.
