Advanced Manufacturing Technology

Through its years of experience, A. S. Thomas, Inc. has developed many advanced manufacturing technologies which have enabled selected customers to establish significant competitive advantage. Thomas Milling is an example of one such manufacturing technology.

Turbine Blade Machining

 Turbine blades machined using NUFORM Level-II. Blade on the left is a gas turbine stator ground to finish via a NUFORM EXPERT SYSTEM on a high performance 6-axis CNC belt grinder. Blade in the middle is a steam turbine bucket milled to a 16 micro-inch finish in one pass! Blade on right is a gas turbine rotor milled to finish from a rough forging in one pass to a 16 mirco-inch finish (.4 micro-meter finish)! The machined blades were produced at high speed, in one pass, using the patented THOMAS MILL, and THOMAS machining methods.

Aircraft Propeller

NUFORM Level-II and THOMAS Milling (patented) are shown machining an aluminum aircraft propeller (36″ blade length, 10″ choord) from a raw forging to finish in one operation.


A. S. Thomas, Inc. has developed a comprehensive Feedscrew Expert System that assures the reliable design and manufacture of package feedscrews. Scroll-Ex technology has been used successfully to produce thousands of high quality feedscrews for most every bottling and packaging industry and application.

The Scroll-Ex label on your feedscrew insures that you are running the finest quality product available. Scroll-Ex is a comprehensive design, manufacturing and quality assurance system that not only produces the smoothest running screw but provides product traceability to insure that all replacement screws will be identical to the original.

This pair of 30″ orientation screws were designed and machined in under three hours.
