Product Specification
Machine Concept

Automatic single station balancing machine. Measurement andcorrection are automatically performed on one station. Part exchange bymanual or gantry loading.

Flexibility

The machine is highly flexible. Only a few work-piece specific parts need to be replaced for change over.

Reliability

Modular design and quality components for best reliability.

Unbalance Measuring

Bearing pedestal type HS and SV16 high precision sensors.

Measuring Unit CAB850

Microprocessor measuring unit CAB850, based on industrial PC, isequipped with LCD touch screen and effectively combines the measuring,control, HMI functions.

Correction Method

Unbalance correction via drilling into crankshaft counterweights byoptimized polar calculation. The HS drilling unit is verticallyarranged above support structure and the drill spindle is perpendicularto crankshaft main axis. The correction is fast and accurate to shortenthe cycle. The correction unit consists of support structure, crossslide unit, radial feeding unit and drilling unit.

Work-piece Conditions

Crankshafts are positioned on sleeve bearing shells that can beadjusted axially. Special designed hook driver turns and indexes thecrankshafts via the first crankpin, which allows convenient partexchange and reduces unbalance measuring error caused by drivecomponents. The asymmetric crankshafts can also be balanced on thisdevice by mounting proper compensation masses.

Safety Protection

Machine is fully closed with interlock and oil mist extractor,which complies with relevant safety and environmental regulation ofEuropean standard.

Lubrication and Cooling

The system consists of chip conveyor, cooling and filteringdevices. It provides coolant and lubricant in different time sequenceunder control of PLC program as per requirement of individualcomponent. This device features greatly in convenient maintenance.
