A floor-type boring machine, also known as a horizontal floor borer or table type boring machine, is a large, industrial machine tool that is used to bore holes in large and heavy workpieces. These machines are called “floor-type” because they are typically large, floor-mounted machines that are capable of handling very large and heavy workpieces.

A floor-type boring machine is typically composed of a large, horizontally-oriented bed that provides a foundation for the machine, a spindle that holds the cutting tool, and a cross-slide that holds the workpiece. The bed is mounted on a series of ways, which provide a stable and precise foundation for the machine, and the cross-slide is mounted on a series of slides, which provide a stable and precise foundation for the workpiece.

The workpiece is mounted on the cross-slide, which is then moved along the bed to bring the workpiece into the cutting area. A boring head, which is connected to the spindle, is then moved towards the workpiece to begin the boring process. The spindle can be adjusted in the vertical direction to adjust the depth of the hole.

These machines can be used to bore large and deep holes, and can also be used to mill and drill. They are commonly used in industries such as aerospace, construction, and heavy machinery manufacturing. Due to their large size, they are typically used to machine very large and heavy workpieces, such as large castings, forgings, and structural components.

Floor-type boring machines require skilled operators, specialized tooling, and a lot of floor space. They are also relatively expensive and require proper maintenance and calibration to ensure accurate and precise boring.
