Abstract:
In a machine for removing material from a workpiece using abrasive elements in a tool assembly, said tool assembly being releasably attached to a driven spindle, a method for adjusting the abrasive elements comprising the steps of:supplying fluid under pressure to said spindle and adapting said spindle to provide a fluid supply to the tool assembly; mounting said abrasive elements within channels of said tool assembly for radial movement therein; engaging said abrasive elements with an adjustment assembly mounted within the tool assembly to convert an axial force to a radial force to actuate said radial movement of the abrasive elements; forming a chamber in the tool assembly; and connecting said fluid supply to said chamber to provide pressurized fluid thereto, wherein said fluid acts on said adjustment assembly to exert an axial force thereon to adjust the position of said abrasive elements; wherein said step of connecting said fluid supply further comprises the steps of: constructing a manifold to receive coolant fluid and distribute fluid to a flood coolant circulation system of said machine; connecting a channel to divert a predetermined amount of coolant fluid from said manifold to said spindle and said abrasive assembly; and connecting said chamber to receive said diverted fluid.
