LCT History

A Pioneer in Crystal Growing.

Full Timeline PDF

Linton Crystal Technologies traces its roots to 1946, when Henry Hemberger of Rochester, NY began developing saw-sharpening equipment for his new Hemberger Machine Company. Success led the firm to incorporate in 1952 as Hamco Machines Inc. and eventually to develop a precision saw for medical use that proved to be equally suitable for cutting silicon crystals for semiconductors.
