EM 8340

 

The EM 8340 is the new top-of-the-range model in Corghi's output of balancing machines with display.

This machine is ideal for users who demand high performance and quick throughput times .

Commands are given using a control panel with integrated luminous data displays on the top of the machine.

This type of interface assures extremely intuitive operation, thanks to user-friendly software giving immediate display of the essential information. Key innovative features include the new digital inside sensor, a sturdy, high-precision device requiring no calibration, and the new-design wheel guard that saves space and provides convenient handling.The QL (pneumatic clamping) version is equipped with

a new fast, accurate clamping system for uncomplicated, low-effort wheel fixing.

As well as the balancing programs, the machine's software also has a series of functions allowing the user to save the three procedures he uses most often, and a help function with two levels: one level describes the selected icon's function and the other indicates, in interactive mode, all the operational procedures for the various programs.

To guarantee outstanding precision and repeatability, the EM8340 has intelligent software that renders the machine immune from outside disturbances such as accidental knocks or vibrations during balancing operations.

 

Main characteristics

  • Electronic balancing machine with microprocessor for off-vehicle balancing of car, van and motorcycle wheels.

  • Balancing speed variable in relation to wheel weight: this optimises the spin time and therefore reduces risks due to revolving parts, as well giving significant energy savings.

  • The body's front is slanted for an optimal working position and easier access to the weight tray.

  • The wheel is located further forward towards the operator, to facilitate adhesive weight fitting.

  • Adjustable head for easier data reading and control of operations.

  • Automatic inside sensor for measuring distance and diameter and for applying adhesive weights in the ALU programs . Horizontal working surface, with diameter measurement up to 27" and width up to 300 mm. Calibration-free digital technology.

  • Automatic outside sensor for width measurement.

  • Automatic position search: on completion of the wheel spin, the machine automatically positions the wheel in the weight application point.

  • High-performance wheel spin and braking unit driven by a servomotor .

  • Shaft clamping brake, automatically or pedal operated.

  • STOP button for immediate machine shutdown.

  • Side flange holder panel.

  • Large cover with trays to take weights of all kinds and the most commonly used accessories.

  • Automatic start when wheel guard is lowered.

  • Wheel guard able to take wheels up to 44" in diameter, but streamlined for easier handling and to reduce the machine's overall dimensions.

  • Dual luminous display.

  • Control panel for simple, intuitive data input.

  • Resolution: 1 g.

  • Unbalance values displayed in grams or ounces with rounding.

  • Balancing modes available:

    • Standard: dynamic on both sides of rims.

    • ALU/ALU P: seven different options for alloy rims.

    • Din. Moto: dynamic on both sides for motorcycle rims.

    • Alu Moto: dynamic on both sides for alloy motorcycle rims.

    • Static: on one plane only.

  • "Shift Plane" program for use of weights in multiples of five grams, with no need for intermediate sizes.

  • "Hidden Weight" program for subdividing the adhesive balancing weight for the outside into two equivalent weights placed behind the spokes of the rim.

  • "Split Weight" program (motorcycle program) allowing weight to be divided into two equivalent parts for positioning on either side of the spoke.

  • "OPT flash" program for the rapid optimising of wheel running noise levels. Shifting the tyre on the rim and a balancing spin will cause the machine to display:

    • Wheel's real unbalance.

    • Minimum unbalance which can obtained by further rotating the tyre on the rim.

  • Utility programs:

    • Calibration

    • Service

    • Diagnostics

  • Three working environments to allow three operators to work at the same time without having to reset the data.

  • VEI (Visual Eccentricity Inspection) for checking for wheel and rim roundness defects.

  • Automatic Quick Lock (QL) wheel clamping with pneumatic locking device (optional).

  • Pneumatic clamping system (optional) for automatic wheel clamping. An alternative to the conventional Quick Lock system.
