1、 Preparation and standardization before operation

1. Workpiece compatibility check
   • Match size and weightConfirm that the diameter, length, and weight of the workpiece are within the allowable range of the equipment (usually the maximum/minimum parameters are indicated on the equipment nameplate or instruction manual). Exceeding the limit may cause damage to the spindle or measurement failure.
   • Balance accuracy requirementsSet a reasonable balance accuracy level (such as G0.4, G1.0) according to the purpose of the workpiece, to avoid excessive correction leading to material waste or insufficient accuracy affecting performance.
   • Verification of clamping method：plusWhen working on new workpieces, it is necessary to verify the reliability of fixtures (such as flanges and expansion sleeves) through trial operation to prevent the workpiece from becoming loose or eccentric during rotation.
2. Equipment status confirmation
   • Power on self-testAfter starting the device, observe whether the display screen shows the "ready" status, and check whether the sensors, motors, and air circuits at each workstation are responding normally.
   • Calibration verificationBefore starting work each day, use standard balance blocks or calibration fixtures to verify the measurement accuracy of the equipment. If the error exceeds ± 5%, recalibration is required.
   • No load trial operationLet the equipment idle for 1-2 cycles, confirm that the logistics systems such as the robotic arm, conveyor belt, and turntable are running smoothly without any jamming or abnormal noise.
3. Parameter Setting Specification
   • speed settingSelect the appropriate speed (usually 1.2-1.5 times the rated speed of the workpiece) based on the material and balance accuracy requirements of the workpiece, to avoid deformation of the workpiece caused by high speed or measurement sensitivity affected by low speed.
   • Parameter optimization for deduplicationDuring processing, gradually adjust the drilling depth/milling amount through the "trial cutting" function, record the optimal parameters and save them as process files, and call them directly for subsequent production.
   • Type change operationWhen changing the workpiece model, it is necessary to use the touch screen or upper computer to "change the model with one click". It is strictly prohibited to manually modify parameters to prevent data confusion.

2、 Monitoring and adjustment during operation

1. Real time data monitoring
   • Vibration value trendObserve the vibration amplitude curve on the display screen. If there is any abnormal fluctuation (such as sudden increase or periodic jumping), immediately stop the machine and check the workpiece clamping or sensor status.
   • Feedback on deduplication effectRecord the remaining unbalance after each weight removal. If it still does not meet the standard after three consecutive corrections, check whether the weight removal tools (such as drill bits and milling cutters) are worn or whether the workpiece material is uniform.
   • Alarm information processingWhen the device prompts alarms such as "sensor failure" or "spindle overload", follow the on-screen instructions to investigate the cause and strictly prohibit forced operation.
2. Logistics system maintenance
   • Mechanical arm collision preventionRegularly check whether the motion trajectory of the robotic arm interferes with the workpiece or fixture, and adjust the position of the limit switch or safety grating.
   • Conveyor belt tension adjustmentIf the conveyor belt slips or deviates, special tools should be used to adjust the tension drum to avoid inaccurate positioning of the workpiece.
   • Rotary positioning calibrationCheck the indexing accuracy of the turntable in each shift (usually measured with a dial gauge), and if the error exceeds 0.1mm, readjust the servo motor parameters.
3. Environmental interference avoidance
   • temperature controlIt is recommended to maintain the operating temperature of the equipment at 15-35 ℃ to avoid sensor drift caused by high temperatures or lubricating oil solidification caused by low temperatures.
   • Vibration isolationInstall the equipment on an independent foundation, with a distance of at least 5 meters from vibration sources such as punching machines and presses, and install shock-absorbing pads if necessary.
   • electromagnetic shieldingStay away from strong electromagnetic interference equipment such as frequency converters and welding machines, or install magnetic ring filters on sensor signal lines.

3、 Key points of maintenance and upkeep

1. Daily cleaning and lubrication
   • Sensor CleaningWipe the surface of the vibration sensor and photoelectric sensor with a clean soft cloth daily to avoid oil stains and metal shavings affecting signal transmission.
   • Spindle lubricationAdd specialized lubricating grease (such as lithium based grease) to the spindle bearings every week, with a recommended amount of oil to prevent excessive leakage.
   • Heavy tool maintenanceClean the cutting edge of the drill bit/milling cutter with an oilstone every time the tool is changed. If the wear exceeds 0.5mm, it needs to be replaced to avoid burning the heavy parts.
2. Regular calibration and testing
   • sensor calibrationVerify the sensitivity of the vibration sensor every 3 months using a standard vibration source (such as a calibrator), with an error margin of ≤± 2%; The photoelectric sensor needs to check the distance between the reflective sticker and the speed measuring head (usually 1-3mm).
   • Spindle dynamic balance detectionEvery six months, use a dynamic balance meter to check the balance status of the spindle itself. If the unbalance exceeds 0.1g · cm, it needs to be returned to the factory for repair.
   • Electrical safety inspectionEvery year, use a megohmmeter to measure the grounding resistance (≤ 4 Ω) and insulation resistance (≥ 1M Ω) of the equipment to prevent the risk of electrical leakage.
3. Life management of key components
   • servo motorReplace the encoder battery every 2 years to avoid loss of position data after power failure.
   • Belt/GearCheck the belt tension and gear wear every 5000 hours of operation. If the belt crack exceeds 1/3 of the width, it needs to be replaced.
   • touch screenAvoid operating with sharp objects and regularly wipe the surface with specialized cleaning agents to prevent touch failure.

4、 Safety protection measures

1. Personnel safety protection
   • protective deviceEnsure that safety barriers, protective door interlocks, and emergency stop buttons are functioning properly, and it is strictly prohibited to shield or short-circuit safety circuits.
   • personal protectionWear goggles, dust masks, and anti smashing shoes during operation to prevent chips from splashing or workpieces from falling off and injuring people.
   • Training requirementsOperators need to undergo professional training and be familiar with the hazardous areas of the equipment (such as the spindle rotation zone and the rework position) and emergency shutdown procedures.
2. Equipment safety design
   • overload protectionThe spindle motor needs to be equipped with a thermal relay or torque limiter, which will automatically shut down when the load exceeds 120% of the rated value.
   • Air source treatmentIf the equipment uses pneumatic components (such as cylinders, vacuum suction cups), air filters and oil mist devices should be installed to prevent air path blockage or component corrosion.
   • Fire prevention measuresFlammable materials are prohibited from being stacked around the equipment, and temperature sensors and smoke alarms are equipped inside the electrical cabinet.
3. Data security backup
   • Regularly exportBackup measurement data and process parameters to external storage devices (such as USB drives and servers) every week to prevent data loss caused by memory saturation.
   • Permission ManagementSet different operation permissions (such as administrator, operator) to prevent unauthorized modification of key parameters or deletion of historical records.

5、 Emergency handling of faults

6、 Long term suspension management

1. Equipment cleaning and protection
   • Clean the chips and oil stains inside the equipment, and apply rust proof oil to exposed parts such as the spindle and guide rail.
   • Cover the equipment with a dust cover to prevent dust from entering the sensors or electrical components.
2. Regular power on operation
   • Start the equipment once a month (for at least 30 minutes each time) to prevent electrical components from getting damp or mechanical parts from rusting.
3. Spare parts reserve
   • Reserve commonly used vulnerable parts (such as sensors, belts, drill bits) to ensure quick resumption of production after discontinuation.

summary

The stable operation of the six station fully automatic balancing machine should follow the principles of "prevention first, standardized operation, regular maintenance, and rapid response". By strictly controlling the adaptability of workpieces, operating parameters, maintenance cycles, and safety protection, the failure rate can be significantly reduced (target ≤ 2%), the equipment life can be extended (usually ≥ 10 years), while ensuring production efficiency and product quality. If encountering complex faults or unsolvable problems, it is necessary to promptly contact the equipment manufacturer or professional maintenance team to avoid greater losses caused by misoperation.
