Device for internal chips cutting machining with a nozzle for flushing cutter fluid on the cutter

摘要

A device for internal chips cutting machining in a bore having a unit for breaking up chips by internal chip cutting machining in the bore. The device includes a principal element with a longitudinal axis and with at least one movable cutter head with a cutter that can be moved essentially perpendicular to the longitudinal axis of the principal element. The device also includes a mechanism for linear motion. A nozzle for flushing of the cutter fluid on the cutter is located onto and can be moved together with the cutter head. A fluid duct is in connection with the nozzle and has a source for cutter fluid at high pressure.

1. A device for internal chips cutting machining in a bore, comprising:
a principal element having a longitudinal axis and at least one moving cutter head including a cutter, wherein the cutter can be moved in a direction at an angle to the longitudinal axis of the principal element between an inside position and an outside position via a mechanism for linear movement; a nozzle arranged to break up chips by flushing of cutter fluid on the cutter, wherein the nozzle is located on and can be moved together with the cutter head; a fluid duct in connection with the nozzle and with a source for pressurized cutter fluid, the fluid duct being a bore in the principal element and a bore in the cutter head; and a tube for transfer of the cutter fluid, the tube having opposed ends and running between the principal element and the cutter head, wherein the tube is fixed at one end to one of the bore in the principal element or the bore in the cutter head and at the other end is glidingly movable in the other of the bore in the principal element or the bore in the cutter head, such that a sliding movement is allowed between a respective bore and the tube, whereby the cutter fluid can be transferred between the principal element and the cutter head.
