Abstract
PURPOSE: To obtain a standard device in which a processing liquid can be supplied to a shaft core hole of a high speed rotary body; such as a rotary spindle, without losing balancing accuracy and also without contacting it.
CONSTITUTION: A jetting pipe 1 is inserted into a shaft core hole 3A of a rotary body 2 leaving a tiny gap (such as an order of 5W100μ), and a liquid to be fed by pressure is pressed into the rotary body 2 through the jetting pipe 1 so that it can be supplied to a work section from a hole 3B on the top end section. The hole of the rotary body 2 is to have a fluid passage having a drawing resistance R1 at a top end section 3B and a liquid-sealing resistance R2 at a tail end section 3A. By making the resistance R2 larger than the resistance R1, leaking of the liquid can be decreased. In order to achieve this, it is to have a gap being as small as 5W100μ and as long as 2W50 mm.
