A CNC 5-axis tool grinding machine is a computer numerical control (CNC) machine tool that is specifically designed to manufacture and sharpen cutting tools. The machine typically has five axes of motion, including the X, Y, Z, A and C axes. These five axes work together to grind and sharpen the cutting edges of the tools.

The X, Y, and Z axes are linear axes that move the tool and the grinding wheel in the horizontal, vertical, and longitudinal directions. The A-axis is a rotary axis that tilts the tool in order to grind at an angle. The C-axis is also a rotary axis that rotates the tool, allowing for the grinding of multi-faceted cutting edges. The tool can also be positioned at various angles and rotated, this allows the machine to perform complex grinding operations and produce precision cutting tools with high accuracy and repeatability.

The machine is typically equipped with a powerful grinding spindle and a high-resolution control system, which enables it to perform precise and efficient grinding operations. The cutting tool can be sharpened quickly and with precision, including creating new cutting edges. CNC 5-axis tool grinding machines are used to manufacture and sharpen a wide variety of cutting tools, such as drills, milling cutters, reamers, and taps. They can also be used to sharpen and maintain specialized tools such as broaches, form tools and gear hobbing cutters.

This type of machines are used in various industries such as aerospace, automotive, medical and many more, where precision cutting tools are required. They are also used in tool and die making and in the production of cutting tools for the metalworking and woodworking industries.
