Uk used cutoff saw machine in the picture is a metal cut-off saw (also called a chop saw or cut-off machine).
Details about it:
The circular part in the center is where the abrasive or toothed cutting disc is mounted.
It’s driven by an electric motor (visible at the back with cooling fins).
The base is designed to hold the workpiece while the disc cuts through metal rods, pipes, or bars.
The box at the top is likely the electrical control housing.
The lever/rod at the side is probably part of the mechanism for operating or locking the saw.
This kind of saw is heavy-duty and is commonly used in workshops for cutting steel, iron, and other metals.
