Machines Model HDVTM are Vertical type
single plane hard Bearing Balancing
Machine provided with Microprocessor
based measuring panel HDVM – 8500 for
balancing Disc shaped Rotors such as
Clutch Plates, Fan Blades , Fly Wheels,
Magnetos, Grinding Wheels, Impellers
etc. Where as HDVTM are vertical type
two plane Hard Bearing Machines provided
with Microprocessor based measuring
panel HDVTM – 8500 for balancing
spinning pots, Spinning spindles etc. |
|
|
|
Both type Machines feature 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 unbalanced
values on DPMS and stops machine.
Keyboard facility provided on measuring
panel for correct Data feeding of Rotor
with one digit accuracy for its
dimensions like ‘RAD’, +1, for single
plane & w, d, r1, r2, +11, +12 for two
plane machines. When Rotor is balanced
within the limits respective LEDs glow
up, indicating no further correction is
necessary. For other details please
refer standard features of measuring
panel HDVM and HDVTM. |
|
|
|
Both type of machines are provided with
electronic companion software to
compensate the unbalanced effect due
eccentricity between rotating ( Spindle
) axis & adaptor (Rotor) axis. |
|
|
|
Standard Features |
|
|
|
|
Digital display for
unbalance indication |
|
|
|
Amount and angle of unbalance for
both planes displayed on separate
DPMs. Hence linear accuracy is very
goos as compared to analog meter +
/- 1 digit for amount and +/-1
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. |
|
|
|
Key-Board |
|
|
|
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 feeding
is 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 of various rotors can be stored against
respective rotor type nos. Hence no need of
measuring of rotor dimensions or rotor data
feeding when repeat balancing operation
required. Just call rotor type no. and machine
is ready for balancing. |
|
|
|
Self Check |
|
|
|
Panel is provided with ‘self-check’ mode which
checks proper functioning of digital displays,
LEDs is cyclic operation. This helps immediate
fault detection. |
|
|
|
|
Additional Features on Demand for Unbalanced Correction (Optional ) |
|
|
|
|
Vertical drilling attachment with
drilling – thrust compensation. |
|
|
|
Horizontal drilling attachment with
drilling thrust compensation. |
|
|
|
Welding attachment. |

|
|
Printer : |
|
|
|
A matrix printer can be connected
through ‘FIE’ software. |
|
|
 |
Compensation Indication : |
|
|
|
‘FIE’ software specially developed with
3 – 99 component indication, is suitable
for balancing of rotor with fixed
locations for balancing correction. |
