Leicester-based Taylor Hobson Ltd (www.taylor-hobson.com) has launched the Talyrond 500H range of roundness instruments that use rotary, vertical and horizontal measuring datums to duplicate a machine tool’s movement and exactly reproduce the workpiece shape.

The resulting high-precision simulation of the cutting tool’s path allows precise control of the manufacturing process.

This single instrument provides five types of measurement: roughness; roundness; contour (radius, angle, height, length and distance, for example); cylindrical mapping; and the measurement of non-round parts (such as cams and pistons).
