    • This invention relates to a method for manufacturing a plurality of longitudinally extending slots in the bore of a component (1). One example of such a component is the sleeve element of an automotive power steering rotary valve. More particularly the invention is directed towards a method of minimising burring of the slot edges of the sleeve component. The method comprises the steps of gripping said component (1) in a gripping means (2) of a workholding device, performing a first cutting operation (5) in which said slot is cut in said bore by a series of progressively deeper cutting strokes of a cutting tool (5), further machining (30) said bore of said component, said machining of said bore being carried out whilst the component remains gripped in said gripping means, characterised in that whilst said component remains gripped in said gripping means said slot undergoes a second cutting operation (5) similar to the first operation.
    • 本发明涉及在组件(1)的孔中制造多个纵向延伸槽的方法。 这种部件的一个例子是汽车动力转向旋转阀的套筒元件。 更具体地,本发明涉及一种使套筒部件的槽边缘的毛刺最小化的方法。 该方法包括以下步骤:在夹持装置的夹持装置(2)中夹持所述部件(1),执行第一切割操作(5),其中通过一系列逐渐更深的切割冲程在所述孔中切割所述狭槽 切割工具(5)进一步加工(30)所述部件的所述孔,所述孔的所述加工被执行,同时部件保持夹持在所述夹持装置中,其特征在于,当所述部件保持夹持在所述抓握装置中时所述槽 经历与第一操作类似的第二切割操作(5)。
