Vertical Balancing Machine with Microprocessor Based measuring Panel (Hard Bearing Models - HDVM & HDVTM)

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 comensate the unbalance effect due eccentricity between rotating ( Spindle ) axis & adaptor (Rotor) axis.

Vertical Single Plane or two plane

Digital display for unbalance indication : Amount and angle of unbalance for both planes displayed on separate DPMs for HDVTM M/c. Hence linear accuracy is very good as compared to analog meter. Accuracy + 1 digit for amount and + 1 degree for angle.

A DPM is provided to indicate balancing speed continuously as a standard feature.

No necessary to stop machine once started. It stops automatically after stabilization of unbalance results.

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, tl1, tl2 are fed by key operation. Hence accuracy of data feeding is accurate up to 1 digit.

Separate LEDs are provided for both planes which glow when unbalance is reduced within balancing tolerance.

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 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.

Panel is provided with ‘self-check’ mode which checks proper functioning of digital displays, LEDs is cyclic operation. This helps immediate fault detection.

  • Vertical drilling attachment with drilling – thrust compensation.
  • Horizontal drilling attachment with drilling thrust compensation.
  • Welding attachment.
  • Any other attachment as per customers requirement.

A matrix printer can be connected through available ‘FIE’ software.

‘FIE’ software specially developed with 3 – 99 component indication, is suitable for balancing of rotor with fixed locations for balancing correction.
