Equipment List and Tolerances
Milling work is done on two CNC bed mills with Centroid controllers. Both machines are capable of 3D milling and regularly hold tolerances of plus or minus .00025”. .They can handle projects that weigh up to 800 lbs and fill a size envelope of up to 40” long, 18” wide and 20” high. When smaller sized cuts are called for, Hi-spinner heads allow spindle speeds as high as 15,000 rpm, making them perfect for small end mills and engraving work. With 3D-Milling capability and the powerful solid modeling software of Virtual Gibbs, they are versatile machines suitable for the most demanding jobs.
Turning work is done on three different lathes. A Yang CNC engine lathe is used for work up to 15 ¾” diameter. Bed length on this machine is 27 ½ “. The Centroid controller and the Gibbs software we use allows us to cut virtually any thread. This lathe will turn complicated profiles and can be set up with gang type tooling and a hydraulic collet chuck for production work. Typical accuracy for this machine is in the .0002” range. A heavy duty 20” Polamco engine lathe is used for bigger jobs. This is a conventional machine with a bed length of 60”. It is perfect for removing large amounts of metal fast. Accuracy is in the plus or minus .0005” range. A Boxford 10” engine lathe is used on any of the less demanding small jobs.
Elecrical Discharge Machining is done on an Ex-Cell-O conventional die sinking machine and is accurate to within .0005”. It is useful for mold making and those odd shaped cuts that can't be done on the lathes or mills. With the powerful CNC capabilities of the lathes and mills we can make virtually any electrode shape. In addition we stock a wide variety of hand tools and are never afraid to use them if that achieves a superior result. Cad/Cam software/File Import
With Virtual Gibbs Cad/Cam software we can create solid models of many complex shapes as well as import solids from a variety sources. We can work from traditional paper drawings, 2D and 3D wireframe geometry or solid models. Gibbs allows import of your geometry in the following formats: IGES, DXF, POINT LIST, PARASOLID, SOLID EDGE, SOLID WORKS, DWG, SAT. Other formats are available on request |
