Dynamic Balancing Machines
with Microprocessor Based Measuring Panel ( Hard Bearing Model - HDCM )
Machines model HDCM are belt driven horizontal type photo scanning Universal Hard Bearing Balancing Machine, provided with microprocessor based measuring panel HDCM - 8500 suitable for balancing different shapes of rotors, of electrical machines, Cylinders, fly wheel, rotor of centrifugal pumps and other type of rotating machines.
These machines are very simple in design. No drive coupling / adaptor etc. required to connect to the rotor to be balanced. It has following
advantages : Cost saving on manufacturing of precision adaptor to connect drive coupling to rotor.
Any rotor can be balanced without losing time in manufacturing of adaptor.
The balancing accuracy of rotor not disturbed due to unbalance in drive coupling / adaptor.
Belt drive machine are more accurate (about 5 times) as compared to end drive machine.
The machines features a very simple operation. The working cycle is fully automatic. From safety point of view a double press push button starts machine, Measures and stores the unbalance values on DPMs for two Plane simultaneously and stops machine. Key board facility provided in measuring panel for correct data feeding of rotor with 1 digit accuracy for its dimensions like A, B, C, R1 & R2. Tolerance limits of both correction planes i.e. +11 & +12 can be feed so that when rotor is balanced within the limits respective LEDs glow up, indicating no further correction necessary. For other details please refer “ features of measuring panel HDCM-8500”
Machine provided with optional vertical drilling attachment
HDCM- 8500 Panel
Standard Features :
• Digital display for unbalance indication
Amount and angle for unbalance for both planes displayed on separate DPMs. Hence linear accuracy is very goos as compared to analog meter + digit for amount and + degree for angle.
• Digital display for RPM indication
A DPM is provided to indicate balancing speed continuously as a standard feature.
• Auto Stop
No necessity to stop machine once started. It stops automatically after stabilization of unbalance results.
• Simultaneous Indication
Amount and angle of unbalance in both planes displayed simultaneously and remains displayed (stored ) till next run. This totally eliminates operation of plane selector and reduces additional time for stabilization of readings in other plane.
Data of rotor dimensions and balancing tolerance i.e. values of A, B, C, R1, R2, t11, t12 are fed by key operation. Hence accuracy of data feedings accurate up to 1 digit.
• Tolerance Indicators
Separate LEDs are provided for both planes which glow when unbalance is reduced within balancing tolerance.
• Auto Range
Depending upon whether unbalance amount is more or less a respective course or fine range gets automatically selected till rotor gets balanced within tolerance limits, Multiplier operation is totally eliminated.
• Data store
Data is provided with 'Self check' mode which checks proper functioning of digital display. LED's is cycle operation. This helps immediate fault detection.
• Self Check
Panel is provided with ‘self-check’ mode which checks proper functioning of digital displays, LEDs is cyclic operation (optional). This helps immediate fault detection.
Additional Featureson demand :
A matrix printer can be connected through ‘FIE’ software. It shows runs till rotor is balanced within balancing tolerance.
Component Indication :
‘FIE’ software specially developed with 3-99 component indication, is suitable for balancing of rotor with fixed locations for balancing correction.
Unbalance Correction :
• Drill attachment 8mm capacity portable drill with supporting overhead railing.
• Separate drilling attachment 19mm. Capacity with a vertical drilling head , manual.
• Portable type reveting hammer (piston type) speed 1800 blows/minute, capacity 6mm in a aluminum suspected from top with rail.
• Tangential belt drive, in addition to standard (suitable for a particular type of rotor for production balancing)
• Longitudinal movement of right hand pedestal by chain & sprocket attachment.

• The balancing speed depends upon selection of the rotor diameter, where drive is to be given and the motor pulley diameter.
• All the machines above operate on mains supply of 400 to 440 V, 3Ø, 50 cycles.
• Due to constant R & D, specifications and features are subject to change without notice.
The dimensions given above are approximate.
