Numerical control woodworking lathe several problems of sensor

Numerical control woodworking lathe is now the use of wood processing enterprises the main equipment, its main is to carry on the processing of wood lathe, automatic processing. Then numerical control woodworking lathe sensor is particularly important, sensor is the first step of automatic detection and automatic control. Then below small make up to introduce you to several numerical control woodworking lathe sensor problem. 1. When have test object proximity switch head, indicating lights, but OUT ( Black line) No output X ( Diameter) Proximity switch fault, this knife automatic return to zero, knife sets out to the maximum diameter of the motor is not stopped, lead to the X axis stepper motor emit squeaks, knife doesn't automatically return to the tail seat. The Z axis ( Length) According to the recent switch fault, this knife automatic return zero, knife set back to the largest diameter cutter set fast moving towards the direction to the tailstock, but the knife hit the tailstock, Z axis stepper motor does not stop, cause the screams of the stepping motor. 2. When there is no test object, light is not bright, but the OUT - Black line) There has always been output X ( Diameter) Proximity switch fault, this knife automatic return to zero, knife sets diameter direction is not action, directly in the direction of the tailstock fast moving knife, knife sets out to tail seat Z axis proximity switch action, knife to stop movement. The Z axis ( Length) According to the recent switch to appear the fault, automatic knife to zero, the knife knife after retiring to the maximum diameter of Taiwan is not moving in the direction of the tailstock, immediately stop. 3. Rapid diagnostic methods: with object detection, Metal, iron, aluminum, brass, copper, etc. ) Proximity switch in the head near and far away from the action, observe the corresponding relay moving to do, when they tested object content induced surface near the proximity switch, relay and accordingly, indicator light, said proximity switch to normal; When test object physical proximity switch induction surface near the proximity switch, the corresponding relay action or object has not been tested or not as he approached the proximity switch induction surface relay and also, at this time is likely to approach switch fails, try to replace the corresponding proximity switch, to detect whether the fault. 4. Proximity switch replacement methods: woodworking lathe cutter on fault proximity switch signal lines cut, remove the fault close to switch, will a knife on the left in the skin peeled off line, the new approach switch signal lines of good color, good insulating tape. Numerical control woodworking lathe sensor problem the reason is that these items, hope you can pay attention to.
