AI Technical Summary
In existing technologies, the control of the extension and retraction of the sawing arm in tunnel sawing machines is not accurate enough, affecting the extension and retraction precision.
An electronic ruler is installed between the sawing arm and the frame. When the sawing arm extends or retracts via the telescopic arm, the electronic ruler simultaneously detects the amount of extension or retraction, thus achieving accurate control.
The telescopic adjustment precision of the sawing arm has been improved, ensuring the accuracy and stability of the cutting process.
