The detection method of an electric circular saw involves multiple aspects of performance testing and safety assessment to ensure its reliability and safety in practical applications. The following are some common detection methods for electric circular saws:

1. Motor performance test

Power and speed test: Test whether the motor's actual power and speed meet the standard requirements to ensure the cutting effect and speed of the electric circular saw.

Start test: Test whether the starting performance of the motor is good, and observe its operation when the motor starts to ensure that the starting process is smooth and without abnormalities.

2. Electronic control system detection

Circuit test: Check whether the electronic control system's circuit is normal, whether the circuit board connection is tight, and ensure that the system's internal connection is good.

Function test: Test the control function of the electric circular saw to ensure its normal operation, including switch control, speed adjustment, etc.

3. Cutting quality evaluation

Cutting effect test: Test whether the electric circular saw's linearity, accuracy, and angle error meet the standard requirements to ensure stable and reliable cutting quality.

Cutting speed test: This test determines whether the cutting speed of the electric circular saw meets the standard requirements and evaluates its working efficiency.

4. Safety detection

Structural safety: To ensure safety during use, check whether the electric circular saw's structure is stable and whether the return spring operation is sensitive.
Protective measures detection: Test whether the electric circular saw's protective devices (such as movable guards, fixed guards, etc.) meet the standard requirements to prevent the saw blade from injuring people.
V. Other test items
Noise test: Measure the electric circular saw's noise level per relevant standards to ensure that it does not produce excessive noise pollution during normal operation.
Radio and television interference level measurement: Test the electric circular saw's interference level with radio and television to ensure that it meets relevant standards and avoids interference with radio and television signals.
Temperature rise test: After the electric circular saw has been running for some time, measure the temperature rise of its various parts to ensure that it does not generate excessive temperature during normal operation, affecting its service life and safety.
Over-torque test: When the temperature rises, the electric circular saw reaches a stable state, and the torque is increased to test its ability to withstand overload.
Durability test: Run the electric circular saw for a long time to test its durability and stability and ensure that it can maintain stable performance during long-term use.
Voltage withstand test: Perform a voltage withstand test on the plug of the electric circular saw to ensure that it can withstand a certain voltage without breakdown or surface flashover.
VI. Appearance and packaging inspection
Appearance inspection: Check the appearance quality of the circular saw, including surface coating, nameplate, fasteners, etc., to ensure that it meets relevant standards and requirements.
Packaging inspection: Check whether the packaging of the circular saw is intact and firm and whether it meets the requirements of transportation and storage.
In summary, the circular saw's detection method involves multiple aspects of performance testing and safety assessment. When conducting the test, it is necessary to strictly follow the relevant standards and requirements to ensure that the circular saw's performance and quality meet the requirements. At the same time, paying attention to the safety and protection measures during the test is necessary to avoid accidents.
