Abstract
A grinding wheel assembly has a tool holder, a mounting shaft connected to the tool holder, and a grinding wheel mounted on the mounting shaft. The tool holder has a first coolant passage defined through the tool holder. The mounting shaft has a second coolant passage communicating with the first coolant passage. The grinding wheel has multiple third coolant passages defined through the grinding wheel and communicating with the second coolant passage. The first coolant passage, the second coolant passage, and the multiple third coolant passages are utilized for a coolant to flow through. Thereby, the grinding wheel and a workpiece can be cooled down without setting up any pipeline and nozzle for the coolant in a grinding machine.

A grinding wheel assembly with a coolant passage system, the grinding wheel assembly comprising:
- a tool holder having
- a first coolant passage defined through the tool holder along a longitudinal direction of the tool holder;
- a mounting shaft connected to the tool holder and having
- a first end connected to the tool holder;
- a second end opposite the first end of the mounting shaft in an axial direction of the mounting shaft;
- a mounting portion located between the first end and the second end and having an external peripheral surface;
- and
- a second coolant passage defined inside the mounting shaft, extending from the first end of the mounting shaft to the external peripheral surface of the mounting portion, and communicating with the first coolant passage of the tool holder;
- and
- a grinding wheel having
- a mounting hole defined through the grinding wheel along a longitudinal direction of the grinding wheel and located on and around the mounting portion of the mounting shaft;
- a grinding surface surrounding the mounting hole;
- and
- at least one third coolant passage defined through the grinding wheel, extending from the mounting hole to the grinding surface, and communicating with the second coolant passage of the mounting shaft, wherein
- the grinding wheel has
- two side surfaces respectively facing two opposite directions, and
- multiple through holes defined through the grinding wheel, extending from one of the two side surfaces of the grinding wheel to the other one of the two side surfaces of the grinding wheel, arranged around the mounting hole of the grinding wheel, and spaced from said third coolant passage;
- the tool holder has
- a first flange located at an end of the tool holder and having an outer peripheral surface and an abutting surface facing the mounting shaft,
- an inserting groove formed in the first flange, formed through the abutting surface of the first flange, and surrounded by the outer peripheral surface of the first flange, and
- multiple adjusting holes radially defined through the first flange and extending from the inserting groove to the outer peripheral surface of the first flange;
- the mounting shaft has an inserting portion disposed at the first end of the mounting shaft and inserted into the inserting groove of the tool holder;
- and
- the grinding wheel assembly has multiple adjusting set screws respectively screwed into the multiple adjusting holes and abut against the inserting portion of the mounting shaft.
