ABSTRACT:
An apparatus for machining a brush seal 19 comprising a clamp for holding the brush seal 14 and a cutting member 16 having a diameter which corresponds to the required finished diameter of the seal 19. The cutting member comprises a cup having an axis of rotation R which is positioned to be coincident with the brush seal axis of rotation S. The machining process is conducted by revolving the mandrel and moving it along its axis of rotation such that an edge portion 38 cuts the bristle material at a required diameter and an outer portion 34 acts to grind the bristle elements to the required diameter.
