Lach Diamond Celebrates Milestones
Two anniversaries mark their pioneering work in manufacturing diamond tools and grinding wheels, first in Germany and then in America.
Posted: March 27, 2017
“When I founded my diamond grindery in 1922, I never would have thought that Lach Diamond would one day be a pioneer in the manufacturing of diamond tools,” said the founder of the company, Jakob Lach, in the early 1980s. Now, celebrating their 95th anniversary, the German company still maintains the tradition of grinding diamonds.
By the end of the 1930s, this historical business segment of “jewelry diamond grinding” for the dressing and profiling of conventional grinding wheels employed 600 diamond grinders. From the end of the 1950s through today their development of polycrystalline diamonds directly or indirectly influenced the daily lives of people. Their discovery of electrical discharge grinding for the forming of polycrystalline diamonds in 1978 was the starting point for a worldwide realignment in the woodworking and plastics processing industries, especially for furniture and parquet flooring, as well as PCB manufacturing. From this discovery, the diamond tooling that was manufactured for milling tools, scoring saws and saw blades increased tool life by three to five months, where as conventional carbide tools had lasted only three to four hours, and their change was costly and time-consuming.
The foundation of Lach Diamond Inc. (Grand Rapids, MI) in 1982 was synonymous with the introduction of this groundbreaking technology in the North American market, documented by trade fairs in Louisville, KY, Los Angeles, CA, and Atlanta, GA. This subsidiary is now in their 35th year of manufacturing and service of superior diamond tooling for wood and wood-like materials in the automotive, aircraft and wind engine industries.
Lach Diamond will exhibit at EMO 2017 in Hannover, the largest European trade show for tools and tooling machines, and will show how their diamond tools and grinding wheels have accelerated many technical innovations during the last fifty years.
