Abstract
Apparatus for machining an angularly disposed array of slots (FIG. 7) concentric with the axis (85) of a bore of a valve sleeve (1) which has a sleeve holder (3) which is rotatably indexed for locating the arcuate position of each slot of the array, a cutting tool (5) positioned on the apparatus to cut a slot in the bore of the sleeve at each indexed location and a boring device (80, 81, 82, 83, 90) for forming the bore co-axially with the array of slots; the operation of the cutting tool (5) and boring device (80, 81, 82, 83, 90) taking place while the sleeve (1) is mounted in the one orientatioln in the holder (3).
Claims16
A method for machining an angularly disposed array of parallel longitudinally extending slots in a bore of a component comprising the steps of gripping said component in a gripping means of a workholding device mounted to an indexable workholding spindle, machining said bore of said component, cutting said array of slots in said bore by a series of progressively deeper cutting strokes of a cutting tool, the cutting of each slot being followed by indexation of said workholding spindle, said cutting of said array of slots being carried out while the component remains gripped in said gripping means in the same location and orientation as during said machining of said bore to thereby maintain the center of the array of said cut slots collinear with the axis of said bore subsequent to machining irrespective of the location and orientation of the component in the workholding device.
Apparatus for machining an angularly disposed array of parallel longitudinally extending slots in a bore of a component, said apparatus comprising means for gripping said component in a workholding device mounted to an indexable workholding spindle, boring means for boring the bore of said component while gripped by said gripping means and slotting means for cutting an array of slots within the bore, wherein said boring means and said slotting means are operable while the component is continuously gripped within the gripping means to thereby maintain the center of the array of said cut slots collinear with the axis of said bore subsequent to the boring by the boring means irrespective of the location and orientation of the component in the workholding device.
A method for machining an angularly disposed array of parallel longitudinally extending slots in a bore of a component comprising the steps of gripping said component in a gripping means of a workholding device mounted to an indexable workholding spindle, cutting said array of slots in said bore by a series of progressively deeper cutting strokes of a cutting tool, the cutting of each slot being followed by indexation of said workholding spindle, further machining said bore of said component, said machining of said bore being carried out while the component remains gripped in said gripping means in the same location and orientation as during said cutting of said array of slots to thereby maintain the center of the array of said cut slots collinear with the axis of said bore subsequent to machining irrespective of the location and orientation of the component in the workholding device.
