摘要： A medical instrument and method for producing a medical instrument with at least one instrument body part made from an instrument body part blank by forming. The at least one instrument body part has at least one deburring face formed by milling. The at least one deburring face includes one or more portions. Each portion extends perpendicularly to a machining plane. A normal to the machining plane defines a deburring longitudinal axis.

摘要： The present application provides a device for correcting an aluminum alloy wheel, which is mainly composed of a frame, an expansion cylinder, a correction motor, a feed motor and the like. A hub positioning unit initially positions a hub to prepare for positioning a center hole expansion sleeve; a hub feed unit performs precise center hole positioning on the hub and completes upward feed movement of the hub; and a tool correction unit completes hub correction through a rotating standard correction cutter head. The device may meet the process requirements of wheels in flow production, improve the runout and balance qualified rate of products, and solve the problems of decentraction of the outer diameter in the first procedure and the second procedure and deformation of rim bulges.

摘要： A method measures an edge of a workpiece by scanning. The scanning is performed by a scanning tool mounted on a moving head of an edge-facing machine while that moving head is moved along the edge to be measured before, during or after an edge facing tool of the edge-facing machine that faces the edge. The method can be performed by an edge-facing machine that includes at least one edge facing tool and that further includes a scanning tool mounted on a movable head of the machine, which head is movable along an edge of a workpiece.

摘要： Described herein is a first method of forming a hole in a workpiece, having a first surface and a second surface opposite the first surface. The method includes forming a first hole, having a first diameter, in the workpiece by passing a first cutter through the workpiece from the first surface to the second surface. Additionally, the method includes forming a chamfer in the second surface of the workpiece concentric with the first hole using a second cutter. The chamfer has a second diameter larger than the first diameter. The method further includes forming a second hole, having a third diameter larger than the first diameter, in the workpiece concentric with the first hole by passing a third cutter through the workpiece from the first surface to the second surface.
