oneProcess monitoring and adjustment

1. Real time observation of surface condition
   • Rough grinding stageCheck if the oxide layer is uniformly removed on the surface without any local residue.
   • Precision grinding stage: UseComparison sample of smoothnessCompare (such as Ra 0.1 μ m, Ra 0.2 μ m) to ensure that the surface roughness meets the standard.
   • Polishing stageCheck whether the surface presents a mirror effect under strong light, without orange peel or scratches.
2. Temperature monitoring
   • Infrared Thermometer: Every5 minutesMeasure the surface temperature of the workpiece once, and the processing temperature of hard materials should be controlled within≤80℃Soft materials ≤60℃.
   • emergency measuresIf the temperature exceeds the standard, immediately suspend processing and wait for the workpiece to cool down40℃After that, increase the water flow or decrease the speed before continuing.
3. Abnormal situation handling
   • Workpiece shakingCheck if the fixture is loose, re fix the workpiece and adjust the feed rate.
   • Polishing wheel blockageImmediately stop the machine, use specialized tools to clean the abrasive residue, and replace the severely clogged polishing wheel.
   • Water flow interruptionImmediately stop the machine, check the water pump, water pipe, and filter screen, clean any blockages, and restart.

2、 Security protection

1. Personal protective equipment
   • gogglesPrevent abrasive splashes from injuring the eyes.
   • Dust maskAvoid inhaling metal dust (such as chromium and nickel dust generated during stainless steel processing).
   • anti-slip glovesPrevent hands from coming into contact with rotating parts or coolant.
2. Equipment safety operation
   • Pre-start inspectionConfirm that the protective cover and emergency stop button are functioning properly, and that the water and power connections are secure.
   • Prohibited during operation：
     • Touch the rotating polishing wheel or workpiece.
     • Adjust the protective cover or safety device.
     • Wear gloves to operate rotating parts (non-contact area only).
   • Emergency shutdownWhen an abnormality occurs, immediately press the emergency stop button to cut off the power and water sources.

3、 Maintenance and upkeep

1. routine maintenance
   • Clean the water tankAfter daily processing, clean the abrasive residue and metal shavings in the water tank to prevent clogging of the water pump.
   • Check the filter screenCheck the integrity of the filter screen weekly and replace it promptly if it is damaged to ensure smooth water flow.
   • lubricated bearingMonthly filling of polishing wheel spindle bearings2 # Lithium based greaseReduce wear and tear.
2. regular maintenance
   • Polishing wheel replacementAccording to the wear and tear, each200-500 hoursReplace the polishing wheel once (hard materials wear out faster).
   • Motor maintenance: Every500 hoursCheck the insulation resistance of the motor to ensure it is ≥1 MΩTo prevent electric leakage.
   • Seal inspection: Every3 monthsCheck the water pump and pipeline seals, replace them in a timely manner when they age, and avoid water leakage.
3. Long term disuse treatment
   • Drain the water tankPrevent residual water from corroding equipment.
   • rust prevention treatmentApply on the surface of the polishing wheel and metal componentsrust preventive oilCover with a dust cover.
   • Storage environmentKeep the equipment storage area dry (humidity ≤60%）, Temperature5-35℃.
