About Gross Machine


R. Bruce Gross, founder of Gross Machine

My dad, R. Bruce Gross, founded Gross Machine in 1976. Our first shop started in the basement of our home, and soon the whole family became involved in the business. As we outgrew the basement, we added equipment to complement our hand turret turning capabilities.

In the mid 80's we moved into an industrial complex. The first CNC lathe came online in 1988, revolutionizing the shop overnight.  Adding almost a machine a year, we now have 5 CNC mills and 7 CNC lathes. Upon my dad's retirement in 2001, I took over the company full time. Since then, Gross Machine has expanded operations, acquiring new machines and equipment to maximize value for customers.
