Common faults and solutions of long measuring machines
Long length machines, as an important processing equipment, are widely used in industries such as mechanical manufacturing, wood processing, and stone processing. Its main function is to perform precise size cutting, sizing and segmentation operations. Due to the harsh working environment and the need for long-term high load operation, equipment failures often occur, which directly affects production efficiency and product quality. Therefore, understanding the common faults and their solutions of long measuring machines is of great significance for improving equipment stability and extending service life.
This article will systematically analyze the common fault phenomena of long measuring machines and provide corresponding solutions to help operators and maintenance personnel better diagnose and troubleshoot problems.

1、 Common fault phenomena of long measuring machines
Long length machine does not start or has difficulty starting
Fault phenomenon: The long ruler machine cannot start normally, the device does not respond when the start button is pressed, or abnormal noise or vibration occurs during the starting process.
Possible reasons:
Power supply issue: Poor contact of power circuit, burnt fuse, or insufficient voltage.
Control system malfunction: Damage to control panel, buttons or contactors.
Motor malfunction: The motor itself has problems, such as burning out or short circuiting the circuit.
The long length machine experiences a lag phenomenon
Fault phenomenon: The long measuring machine experiences obvious lagging during operation, unable to run smoothly, and even stops.
Possible reasons:
Wear and tear of guide rails: Long term use causes wear and tear on the guide rails and sliders, resulting in gaps that prevent the equipment from moving smoothly.
Insufficient lubrication: Lack of effective lubrication causes excessive friction between mechanical components, leading to jamming.
Foreign object obstruction: If cutting waste or debris is generated during the processing, it may block machine components or transmission systems, resulting in jamming.
Abnormal vibration of the long measuring machine
Fault phenomenon: During operation, the long measuring machine experiences abnormal vibration, even producing noise or strong vibrations.
Possible reasons:
Uneven machine base: The foundation or workbench of the long machine is unstable, which may be due to uneven foundation or unstable installation.
Bearing wear: If the bearings of the transmission system are severely worn, it may cause unbalanced operation and vibration.
Improper installation of cutting tools: Improper, loose, or misaligned installation of cutting tools may also cause vibration.
The cutting accuracy of the long ruler machine does not meet the standard
Fault phenomenon: When cutting with a long measuring machine, the dimensions of the workpiece are inaccurate or the smoothness of the cutting surface is poor, resulting in product quality not meeting the requirements.
Possible reasons:
Unstable feeding speed: The feeding system is unstable or the speed is uneven, resulting in cutting errors.
Tool wear: After long-term use, the tool wears severely and the cutting effect deteriorates.
Loose mechanical components: Loose or aging mechanical components cause positional deviation during the cutting process.
Electrical system malfunction of the long measuring machine
Fault phenomenon: The electrical system of the equipment has malfunctioned, manifested as the motor being unable to start and stop, the control panel not responding, and electrical components overheating.
Possible reasons:
Aging of electrical components: Relays, contactors, switches, and other electrical components will age after long-term use, affecting the normal operation of the equipment.
Circuit short circuit or open circuit: An interruption or short circuit in an electrical circuit that causes the electrical system to malfunction.
Unstable power supply: The unstable power supply voltage causes electrical equipment to malfunction.
The long ruler machine produces abnormal noise
Fault phenomenon: The equipment emits abnormal noise during operation, which is loud and sometimes accompanied by sound or metal friction.
Possible reasons:
Bearing damage: Damage or poor lubrication of bearings in the transmission system can lead to increased friction and noise.
Gear wear: If the meshing part of the gear is worn, it will cause excessive friction noise.
Foreign object jamming: If there are foreign objects or debris jamming in the machine, it can also cause abnormal noise.

2、 Solution to the malfunction of the long measuring machine
The solution to the problem of the long ruler machine not starting or having difficulty starting
Check power supply issue: First, check if the power supply circuit is normal and confirm if the power supply voltage meets the equipment requirements. Replace the burnt fuse to ensure stable voltage.
Check the control system: Check if the control components such as the start button, contactor, and relay are functioning properly. If a malfunction is found, replace the damaged parts in a timely manner.
Check the motor: Check if there is a short circuit or open circuit in the motor circuit. If the motor malfunctions, it needs to be replaced or repaired.
The solution to the lag of the long length machine
Check the guide rail and slider: Check for wear or foreign objects on the guide rail and slider. If any problems are found, replace the worn parts in a timely manner or clean the waste on the guide rail.
Add lubricating oil: Regularly check and add lubricating oil to mechanical components to ensure good lubrication between them and reduce friction.
Cleaning up debris: During the processing, it is necessary to regularly clean up waste materials to prevent debris from getting stuck in machine components.
Solution to abnormal vibration of long measuring machines
Check the stability of the machine base: confirm whether the equipment is installed firmly and whether the foundation is flat. If unevenness is found, readjust the device position to ensure the stability of the machine base.
Check the bearings and transmission system: Check whether the bearings are worn or damaged, and replace aging parts in a timely manner. Check the alignment of the transmission system to ensure that there is no looseness or damage to the transmission parts such as gears and belts.
Tool adjustment: Check whether the tool is loose, whether the tool is installed correctly, and whether the sharpness of the tool meets the working requirements.
The solution to the substandard cutting accuracy of the long ruler machine
Check the feeding system: Confirm if the feeding speed is uniform and if there are any unstable conditions. If any problems are found, adjust the feeding device to maintain stable feeding.
Check the cutting tools: Check the wear of the tools, replace or grind them in a timely manner, and maintain sharp cutting.
Check the looseness of mechanical components: Check whether all components at the cutting site are firm, ensure that there is no looseness during the cutting process, and prevent positional deviation.
Solution to electrical system faults of long measuring machines
Inspect electrical components: Regularly check for aging of electrical components and replace damaged relays, contactors, and other electrical components in a timely manner.
Check the circuit: Check the connection of the electrical circuit, check for any open or short circuits, and ensure that the circuit is unobstructed.
Stable power supply: If the power supply is found to be unstable, it is recommended to install a voltage regulator for the equipment to maintain a stable power supply.
Solution to abnormal noise of long length machine
Check the bearings and lubrication condition: Check whether the bearings in the transmission system are worn. If there are any problems, replace them in a timely manner and add lubricating oil.
Check the gears and transmission system: Check the meshing condition of the gears. If wear or looseness is found, adjust or replace the gears in a timely manner.
Cleaning foreign objects: Check if there are any foreign objects stuck in the equipment, regularly clean the waste or debris inside the equipment to prevent them from affecting normal operation.
