Title: Bimal Kumar Chaterjee: Innovator in Steel Component Manufacturing

Introduction

Bimal Kumar Chaterjee is a notable inventor based in Jackson, TN (US). He has made significant contributions to the field of manufacturing, particularly in the development of steel components for power tools. With a total of 2 patents, his work has had a lasting impact on the industry.

Latest Patents

Chaterjee's latest patents include a process for the manufacture of steel components for screw gun clutches. This innovative method involves melting and mixing a readily available base steel with alloying elements. The molten steel is then cast into near-net-shape using an investment casting process. This approach is cost-competitive compared to forming components from steel with fewer alloying elements. Specifically, clutch plates for drill/drivers or screw guns can be produced from steels containing significant amounts of nickel and chromium, such as SAE 9310 steel, or from steels with high total amounts of molybdenum and tungsten, like AISI M2 steel.

Another patent focuses on a method of producing parts that exhibit improved wear, fatigue, and corrosion resistance. This process treats medium alloy, low carbon steel pieces through carburizing followed by nitriding. The treatment enhances the durability and cost-effectiveness of steel parts, making it particularly useful for automotive and marine applications, as well as for pumps and power tools. A specific example of this innovation is the blade-carrying reciprocating shaft for a reciprocating power saw.
