Air and coolant hose for milling

For the coolant hose to fit this small milling machine, to save room and to keep the machine clean, decided to pass the plastic tube inside the headstock housing.

Parts for the air and coolant hose for milling

Made a part from hex brass stock threaded M8. On one side the M8 thread is to fix the coolant hose on the milling machine headstock housing with a M8 nut.

Removed the threaded end on the hose plastic connector and made a M8 thread on the inside of the plastic hose connector. On the front of the brass part that fix the coolant hose to the milling machine, a M8 thread fits the thread made on the plastic connector.

The brass part was drilled to 4mm on rear to fit the outer diameter of the plastic tube.

The air and coolant hose mounted on the milling spindle

The air and coolant hose mounted on the milling machine headstock housing, keeping room to access the milling spindle for tool mounting without trouble. The plastic tube passes inside the headstock housing.
