Title: Mark Andrew Stocker: Innovator in Grinding Technology

Introduction

Mark Andrew Stocker is a notable inventor based in East Hunsbury, GB. He has made significant contributions to the field of grinding technology, holding a total of nine patents. His innovative approaches have advanced the methods used in precision grinding, particularly for disc-like workpieces.

Latest Patents

One of Stocker's latest patents is for a method of edge grinding that involves positioning a grooved grinding wheel relative to a disc-like circular workpiece. This method includes steps such as mounting the workpiece for rotation about a first axis and the grinding wheel for rotation about a second parallel axis. The process involves relative movement between the workpiece and the wheel to engage the rim of the wheel within the groove, followed by a preliminary grind. The position of the wheel is then axially adjusted based on measurements taken from the rim profile produced during the preliminary grind. This cycle of grinding and measuring is repeated until the desired accuracy is achieved. The final position of the grooved grinding wheel is utilized for grinding future wafers.

Another significant patent involves a grinding pin designed for grinding machines. This grinding pin features a metal spindle for mounting in a grinding machine, along with a cylindrical region that has axially spaced sections of fine grit and rough grit. The design allows for the effective grinding of notches in the edges of disc workpieces, such as semiconductor wafers.
