The assembly of clear corners of plastic doors and windows should meet the relevant standards. For various process problems encountered in assembly, it should be based on mechanical principles, equipment structure, equipment parameter settings, reasonable adjustament of equipment, profile materials, geometric dimension accuracy, working environment , Methods of operation and other aspects of analysis and exclusion. The basic maintenance ideas are: fault investigation, gas path analysis, circuit analysis, gas cut-off inspection, power-off inspection, ventilation inspection, power-on inspection, etc. The following list illustrates the common faults and troubleshooting methods of plastic door and window corner cleaning equipment :
| Fault | reason | problem analysis | Method of exclusion |
| The whole machine does not start | trip switch problem | The travel switch is not connected to the power supply, so that the whole machine does not operate | Adjust the installation position of the travel switch or replace the travel switch |
| There is a problem with the main power supply line | The neutral line is missing after the main power supply enters the line, and the power indicator light is dimly lit | There is plastic debris inside the power switch, causing the neutral line to be disconnected | |
| No power input | See if the power light is on | Connect the power cord | |
| Low Voltage Circuit Breaker Problems | Low voltage circuit breaker off | Turn on the low voltage circuit breaker | |
| Dial cylinder does not work | proximity switch problem | The front two positioning proximity switches do not work | Adjust proximity switch position |
| Poor flat corners | Poor adjustment of the upper and lower pull knives | Adjust the upper and lower pull knife to the appropriate | |
| Angle blade problem | Angle cleaning blade is not sharp | grinding blade | |
| profile placement problem | Improper placement of profiles | Correct placement of profiles | |
| waste problem | Cleaning the corners of the tongue part stuck waste | remove debris | |
| Angle cleaning machine type 01 | Wrong movement at work | Proximity switch broken no signal input | Replace proximity switch |
| PC failure | Repair or replace a PC | ||
| line failure | check line | ||
| CNC angle cleaning machine | The motor does not turn after turning on | Broken relay | replace relay |
| Phase line loss or neutral line open circuit | Check the phase and neutral wires of the power supply | ||
| A trip or fire | short circuit | check line | |
| There is a deflection phenomenon in the upper and lower cleaning seams | Improper adjustment of positioning eccentric column or broach eccentric column | Adjust the eccentric column | |
| broach too blunt | Grinding or replacing the broach | ||
| Unqualified welding profile | re-welding profiles | ||
| Milling outer corner material | Milling cutter feed rate is too fast | Adjust operating parameters | |
| material too brittle | replacement material | ||
| system error | System Troubleshooting |
