Offering a range of capabilities, Jerpbak-Bayless provides superior custom OD grinding, thread grinding, and helical milling services. From thread and spline milling to precision grinding and polishing, our machinery can uphold a +/-.0005 inch precision tolerance, and a .0003 inch concentricity. We can work with parts weighing up to five tons with unlimited length capacity. Our advanced machinery and highly experienced machinists can also handle a variety of materials such as nickel based alloys, stainless steels, alloy steels, aluminum, bronze and cast iron.
Our equipment inventory includes a variety of thread cutting machines. We grind threads, chase threads, mill threads and roll threads. Many of these machines have been specially retro fitted to cut much more advanced thread forms than usually possible. Our largest thread milling machine is capable of cutting threads 228 inches long in one setup. If your part is 6.0 inches in diameter or less the length is unlimited! For our clients with larger diameter requirements we have specially adapted CNC lathes that can handle most standard and special thread forms up to a 39.4 inch diameter and a 196.8" part length. We routinely cut ACME threads, SQUARE threads, and TRAPIZIODAL threads as well as all forms of V-threads. With our portable CMM we can inspect many aspects of your custom threads right in the machine. Jerpbak Bayless can also perform pre and post machining services on your threaded or non-threaded parts.
We have a wide variety of equipment in our 42,000 square foot facility which includes, but is not limited to, a CNC OD Grinder that can grind parts measuring up to 14x233 inches and a CNC deep hole gun with a drilling capacity of 1.5 inches diameter in a work envelope of 40x 40 x36 inches. With our 9 CNC vertical and horizontal machining centers we can handle most milling requirements. Our biggest machine has 144" of X axis travel in a full 4 axis configuration. We also employ a variety of quality control inspection machines, such as a portable CMM, an optical comparator, and other standard metrology instruments, which helps us to ensure the quality of all our manufactured products.
From axle, coupling, and large custom shafts, our advanced, CNC turning, CNC OD grinding, thread grinding and helical milling services are ISO compliant and can be used for a variety of applications. At Jerpbak- Bayless, we routinely serve a wide range of industries, including mining, HVAC, plastics, food equipment, construction and marine.
