Application: This device is applicable to test the closing time and mechanical strength of lower guard for circular saws.
Test sample: Circular saws
Feature: The saw is to be set for a 90°cut and oriented in the horizontal plane. The lower guard is to be cycled from the full closed position to the maximum open working position and then released for 50000 cycles at a rate not less than 10 cycles per minute. The cycle numbers recorded by a position sensor. Following the cycle, the closure time shall not exceed 0.3s. The device record the times when detected closure time exceed 0.3s. When preset test times completed, device record the last closure time and stop automatically.
