Maintaining a PCB V-scoring machine is crucial to ensuring its longevity, reliability, and optimal performance. Like any other machine, maintenance and care of the machine ensures it functions properly and efficiently. Neglecting the machine may result in breakdown and damages.

It may be helpful to follow a regular maintenance schedule. Daily and weekly, checks and parts to be cleaned are as follows. The entire machine should be cleaned of any dust or debris after any cutting operation. In addition, the following parts may be cleaned weekly.

• The conveyor belt should be wiped with a damp cloth to remove any oily or sticky substances and cleaned with a soft brush.
• The blade can be cleaned gently with a soft brush to remove any residual material or dust. It should be inspected for wear and damage and lightly lubricated with machine oil before replacing it.
• The vacuum system filters should be removed and cleaned with compressed air.
• The inspection tables should be cleaned to remove any glass fiber dust or debris to ensure no rubbish is left on the PCB before the next step.

Once a month, more in-depth maintenance tasks may include the following:

• Lubricating the machine's moving parts helps to reduce friction and joint wear.
• Vacuum pump maintenance includes changing the filters and inspecting the pump for required maintenance or cleaning.
• Calibration of the scoring blade may be required if it is not aligned properly after replacing it or if the machine has not been used for an extended period.
• Removing any glass fiber dust from hepa filters in the extraction system is also essential to ensure that the machine functions properly.

Finally, a thorough inspection of all critical components will ensure that any issues are detected early and rectified before they cause any further damage.
