Operation is simplified by perma-nent calibration, ergonomic designand logical sequence of design and a wide range ofaccessories make series HM balan-cing Machines an extremely series HM universal balan-cing Machines are therefore a high-ly efficient investment for balancingindividual rotors and small applicationHigh Balancing accuracy Easily upgradable due to modulardesign and wide range of accessoriesHard-bearing design provides forquick change-over from one rotor tothe next Ergonomically designed measuringinstrumentation type CAB 700 orCAB 920 with superior functionalityExtensive safety equipment for allprotection classesHorizontal Balancing Machines series HM 20, HM 3/HM 30RM 2528-1 e Special features High ease of operation.

2 Hard-bearing design eliminates theneed for calibration runs. machine provides for unbalancecorrection in two planes orseparate correction of static andcouple unbalance. Rotors can be mounted on theiroriginal shaft or on a balancingarbor. Balancing with mountedanti-friction bearings availableas option. Indexing angle display in caseof belt drive. Automatic measuring cycle withselectable, infinitely variableacceleration, measuring anddeceleration times. Upgradable with many supple-mentary modules, for bearing pedestals: Slim, robust bearingpedestals ensure high overall stiffness, highlinearity and extremely low damping. Use ofthe Schenck hard-bearing principle, with themiddle section of the bearing pedestal desi-gned as sturdy dynamometer.

Closing of protection of automatic measuringsequence: Acceleration, determination anddisplay of unbalance on themeasuring instrument, decelera-tion. The measured unbalancevalues are retained after themeasuring run is completed. Opening of the protection device,manual unbalance correction (ifnecessary). Verification of residual unba-lance (the measuring unit indica-tes whether the required tole-rance has been reached), andunloading of the rotor from of a drive system is deter-mined by the shape or your of different drivesystems on one machine are possi-ble.

Over-slung belt drives (BK) are used forhigh rotor throughput, universal-joint drives (U) in cases where ahigh drive power is required. Drive systemClass B protectionClass C protectionMeasuring unitsEnclosuresThe choice of protective enclosureis determined by the danger therotor presents, with due considera-tion to Balancing speed, method ofunbalance correction and maximumpenetration energy of rotor compo-nents or on the varying protec-tion requirements, ISO 7475 speci-fies five protection classes (0, A, B,C, D) for Balancing Machines . series HM Balancing machinesusually require Class B or Class Cenclosures. Safety class B shouldbe chosen, if contact with the rotoror parts of the drive system mayresult in injury.

5 Class C is to beused in cases, where the hazard offragments detaching from the rotorcannot be ruled out entirely. Thesize, shape, hardness and tangentialspeed of a projected fragment areused to calculate the penetration potential. The safety enclosure must be capable of containing any such projected rotor unit CAB 700 Balancing in research and develop-ment, in a repair shop, in one-offproduction or in the production ofsmall batches makes entirely diffe-rent demands on the measuringsystems. Schenck has the right microproces-sor-based measuring instrumentati-on for you, whatever your balancingtask. All measuring units offer a con-sistent operating philosophy, hig-hest accuracy for processing ofmeasured data, and a clear andeasy-to-read display.

6 They processmeasurement signals and providefor direct display of amount andangular position of calibration means thatonly very few geometric data have to be entered to set the unit for anew rotor type. Features such asstorage of measured values, inde-xing display or the display ofinstructions help the user to per-form the Balancing process quicklyand efficiently. The CAB 920 offers extended func-tionality and superior ergonomics.
