Secondary CNC Machining
General Foundry Service’s Machine shop
General Foundry Service was among the first foundries to offer in-house machining in the late 1980’s. The machine shop was started because of poor experiences with outside machine shops and long lead times. Multiple foundry processes allow General Foundry to create the nearest net shape, helping to reduce machining, saving customers time and money. The machine shop shares a wall with our foundries and our team is always discussing how we can improve our castings on any given project to reduce scrap and increase yields internally and externally. We have 15 vertical CNC mills and 1 CNC lathe. Our three largest machines, with a 64” x 40” x 38” travel, have cranes to handle extremely heavy geometries safely. With 3 and 4 axis capabilities, multiple rotary tables and true 3d machining, we can handle many of the more challenging and tighter tolerance jobs. Almost half of our machines have in machine probes, allowing us to accurately pick up starting points. All of our programming is done in-house using SurfCam and we create custom fixtures for each geometry and job. As part of our design reviews, we help customer’s move from cast datums to machined datums, and ask questions upfront regarding design intent, what’s critical, tolerances and GD&T. We look forward to have a dialog with you soon.
