GPM Mfg Inc is a family run business that began in 1984 in a small garage on Chicago’s northwest side, doing manual machining. We purchased our first CNC vertical machining center in 1987 and added a CNC lathe in 1988. Since then we’ve grown into a shop specializing in both CNC turning and milling operations. In September of 2005, we moved into our brand new 20,000 square foot facility in Lake Zurich, Illinois and recently added our 14th & 15th CNC machines.  Like many other shops, we specialize in high precision CNC turning and milling. What separates us from our competitors is our service, responsiveness and perhaps most importantly our willingness to take on difficult and challenging jobs that other shops may be afraid to tackle.
