CNC Milling

CNC milling is a specific form of computer numerical controlled (CNC) machining. Milling itself is a machining process similar to both drilling and cutting, and able to achieve many of the operations performed by cutting and drilling machines. Like drilling, milling uses a rotating cylindrical cutting tool.

CNC Turning

This operation is one of the most basic machining processes. That is, the part is rotated while a single point cutting tool is moved parallel to the axis of rotation. Turning can be done on the external surface of the part as well as internally (boring).


Our facilities have state of the art equipment to better provide hi quality products and services. We are constantly training and learning the modern techniques necessary to satisfy the needs of our customers. Our serene setting is in beautiful Alton.

Quality Control

We employ a system of maintaining standards in manufactured products by testing a sample of the output against the specification provided by the customer. These standars do not vary and always conform to the strict tolerances that have been established.
