Method of forming a recess in a body
摘要：
A method of forming a recess in a body (10; 24) having a cylindrical surface, and in particular a metering valve component, utilises a grinding wheel (32) having a first axis (33), preferably a drive axis, and a circumferential surface (34) concave to a second axis (37) that is substantially orthogonal to the first axis (33). The grinding wheel (32) also includes first and second opposing radial surfaces (36, 38) of substantially planar form. At least a portion of the circumferential surface (34) of the grinding wheel (32) is engaged with an outer surface of the body (10; 24) and the grinding wheel (32) is rotated about the drive axis (33) to cause a region of the body (10; 24) to be ground, thereby to define a recess (40; 46) in the body having a periphery (42; 48) at the cylindrical surface including at least two substantially square corners (41a, 41b, 41c, 41d; 49a, 49b) and at least one pair of substantially parallel facing edges (43a, 43b, 43c, 43d; 47a, 47b). The method is conveniently used to provide an opening or port of at least partially square or rectangular form in a cylindrical body such as a metering valve member (24) or a metering valve sleeve (10) of a metering valve arrangement.
摘要（中）：

在具有圆柱形表面的本体（10; 24）中形成凹部的方法，特别是计量阀部件的方法利用具有第一轴线（33），优选地驱动轴线的磨轮（32）和周向 与第一轴线（33）基本正交的第二轴线（37）凹入的表面（34）。 砂轮（32）还包括基本上平面形式的第一和第二相对的径向表面（36,38）。 砂轮（32）的圆周表面（34）的至少一部分与主体（10; 24）的外表面接合，并且砂轮（32）围绕驱动轴线（33）旋转以引起 所述本体（10; 24）的区域被研磨，从而在所述主体中限定出在所述圆柱形表面处具有至少两个基本上正方形的角（41a，41b）的周边（42; 48）的凹槽（40; 46） ，41c，41d; 49a，49b）和至少一对基本平行的面对边缘（43a，43b，43c，43d; 47a，47b）。 该方法方便地用于在诸如计量阀装置的计量阀构件（24）或计量阀套（10）的圆柱体中提供至少部分正方形或矩形形式的开口或端口。
