We are offering high speed balancer. The abro hr series has worked with ms man turbo to balance rotors at speeds of up to 18,000 rpm and achieve low vibration levels that were never thought to be possible. Those days are gone when in order to meet to meet specifications like api-612 on high speed balancing machine, one must employ api deviations. On the hr series you can meet all existing balancing and vibrations standards for turbines, compressors and armatures. The abro high speed balancing machines combine high rigidity with high sensitivity. Site conditions can be created by selecting the desired stiffness and if necessary by using the actual bearings of the rotor. Therefore, accurate low speed and high speed balancing is possible for rotors with widely varying weights and speeds.

We are offering ultra low speed balancing abro has designed and manufactured the worlds largest vertical balancer. Interestingly, this balancer is also runs at the lowest speed of 6 rpm. Due to superior sensor and electronics ( both designed and manufactured by abro in-house ), abro is the only company in the world today that can balance large jobs at ultra low speed of as low as 6 rpm accurately.

We are offering 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. 2. Brief description of machine.

We are offering universal vertical balancing machine. Balancing machine with vertical spindles are ideal for mass production. Balancing machine with vertical spindles with vertical spindles are ideal for mass production. Standard vertical machines incorporate a precision spindle on which components like flywheels, special centrifuges, clutch assemblies, textile spindles, nylon pots, turbine wheels, satellites, etc. Can be mounted and balanced. Simple loading arrangements and correction of unbalance on the machine by drilling etc. Result in low production times.

We are offering machine setting unlike soft bearing machines, which have complicated calibration procedures, in abro 'hard bearing' machines the procedure is extremely simple. After mounting the job on the machine, one has simply to feed the following: (1) balancing speed desired; (2) job configuration in use; (3) the job dimensions a,b,c,rl and rr. The machine is now ready for operation. Nothing else has to be done. Machine operation the basic design of the abro machines makes their operation very simple. Besides, the auxiliary equipment is a further help, e.g. In the case of crankshaft, multiplane electronic units giving the unbalance simultaneously for various correction planes that lie on the counterweights ; pneumatic job clamping and raising devices facilitate drilling on the machine, drilling on the machine, drilling units with electrical traversing and automatic positioning, complete with chip suction arrangements add up to make balancing simpler and faster. Similarly, for other applications, abro offer a variety of auxiliary equipment. Therefore, to get the most suitable solution, spell your exact requirement to abro.

We offer balancing instrumentation. The mp-102 electronics is a microprocessor-based system for precision balancing. It has a crt display, which is used as read out for unbalance readings as well as for viewing various other rotor data parameters. The software employed here is menu driven for user convenience. Rotor description, dimensions, geometry, balancing tolerances, method of correction (addremove, polar component) and balancing speed are fed into the electronic memory of the unit via the keyboard. Each set of rotor data pertaining to one rotor is allotted a code number by which the rotor data is recalled from the memory at the time of balancing run. Adequate memory is provided for storing data on the hard disc. The microprocessor unit carries out the entire set of computations digitally and displays the result on the crt screen. The correction results are displayed in bold letters using specially designed graphics to suit the shop floor conditions. The results can be in polar or component form. The number of components and the angle of the first component can be different in the planes and can be varied depending upon the job. The unit also determines whether the residual unbalance is within the balancing speed is checked and appropriate messages are displayed on the crt display to avoid balancing at wrong speeds. The mp-102 unit is extremely useful where a large verify of rotors are encountered in the production process and changeover from one type of rotor to another is done frequently. It also allows the use of the printout system for recording the balancing results.

Vibration instrumentation & condition monitoring a) vibration monitoring a range of vibration meters such as the mv 100, mv 200, mv 400, mv 410 (b) etc. Are available to measure vibrations. The mv-410 (b) is specially suited for evaluating the condition of bearings in actual operations besides vibration measurement. A range of vibration analyzers like mv 306, mv 310, mv 320 etc. Are available for vibration analysis ( frequency analysis) in addition to vibration vibration measurement. Field balancing can be done with a vibration analyzer by the use of stroboscope.
