#How to determine the safety risks of a twisted axis CNC bending machine
## 1. Electrical safety
###Importancia
Electrical safety is a key link in the safety risk assessment of twisted axis CNC bending machines. Electrical system failures may result in equipment shutdown, performance degradation, and even fire or electric shock accidents.
###Judgment method
-Check the power cord: Confirm that the power cord is not exposed, aged, or damaged, and that the connectors are securely connected.
-Check the control box: Observe whether there are any abnormal phenomena such as dust accumulation, overheating of components, and burning inside the control box.
-Grounding inspection: Ensure that the equipment is properly grounded to avoid electrical leakage or static electricity accumulation.
-Electrical component inspection: Check whether the motor, contactor, relay and other electrical components are working properly without any abnormal noise or overheating.
## 2. Mechanical safety
###Importancia
Mechanical safety is an important aspect of safety risk assessment for twisted axis CNC bending machines. Mechanical failures may result in equipment damage, personnel injury, or production accidents.
###Judgment method
-Mechanical component inspection: Check whether the transmission shaft, bearings, gears and other mechanical components of the equipment are severely worn or have cracks.
-Fastener Inspection: Check if screws, nuts, and other fasteners are loose or missing to ensure the stability of the equipment structure.
-Lubrication system inspection: Confirm that the lubrication system is working properly, without any poor lubrication or oil leakage.
-Safety device inspection: Check whether safety devices such as safety doors and emergency stop buttons are intact and can work normally when needed.
## 3. Operational safety
###Importancia
Operational safety is the core content of safety risk assessment for twisted axis CNC bending machines. Improper operation may result in equipment damage, personnel injury, or production accidents.
###Judgment method
-Review of Operating Procedures: Check whether clear operating procedures have been established and whether the content is comprehensive and accurate.
-Operator Training Status: Understand whether the operator has received professional training, is familiar with equipment operating procedures and safety precautions.
-On site observation: Observe the operator’s operation process on site and check for any violations or improper operations.
-Assessment of Work Environment: Evaluate whether the work environment is safe, orderly, and whether there are any safety hazards.
## 4. Noise and Protection
###Importancia
Noise not only affects the efficiency and health of operators, but may also mask equipment malfunctions or abnormal sounds, increasing safety risks.
###Judgment method
-* * Noise testing * *: Use noise measuring instruments to test the noise generated by the equipment to ensure that the noise level meets relevant standards.
-* * Protective measures inspection * *: Check if noise protection measures such as earplugs, earmuffs, etc. are equipped to ensure that the operator receives necessary protection.
-Assessment of Sound Insulation Measures: Evaluate whether sound insulation measures have been taken around the equipment to reduce the impact of noise on the surrounding environment.
## 5. Renovation and Upgrade
###Importancia
With the development of technology and the aging of equipment, twisted axis CNC bending machines may need to be modified or upgraded to improve their performance and safety.
###Judgment method
-* * Performance evaluation * *: Evaluate the performance of the device to determine whether it meets current production needs, whether there are performance bottlenecks or security risks.
-Technical transformation analysis: Analyze the feasibility and necessity of technical transformation, such as adopting new technologies, replacing new components, etc., to improve the performance and safety of equipment.
-* * Safety assessment * *: Conduct safety assessments during the renovation or upgrade process to ensure that the renovated equipment meets relevant safety standards and requirements.
-* * Training and Support * *: Provide necessary training and technical support to operators to enable them to proficiently master the operation and maintenance methods of new equipment.
Based on the above five aspects of judgment, the safety risks of the twisted axis CNC bending machine can be comprehensively evaluated, and corresponding measures can be taken to reduce the risks and ensure the safe operation of the equipment.
