[0002] Spot facing equipment is a professional tool used for processing metal surfaces. It is mainly used for opening holes, trimming holes and surface treatment. Its working principle is to use a rotating tool to cut the metal surface.

Spot facing equipment usually includes components such as a spindle, cutting tool, feed system and control system, and can adjust the tool speed and feed rate according to different processing requirements.

[0003] Countersinking equipment is suitable for processing various metal materials, such as bridge bearings. Bridge bearings are an important component of bridge structures, used to support and transfer the load on the bridge to the piers or abutments, while allowing the bridge to produce axial displacement and rotation under the influence of force and temperature. Bearings are usually made of rubber, steel, concrete and other materials. Their design takes into account factors such as the structural form, load characteristics and foundation conditions of the bridge. The main function of bridge bearings is to protect the bridge structure from external vibration and deformation, ensure the safe and stable operation of the bridge, and extend its service life.
