Precision Metal Machining

Established in 1974 as a Davenport Machine Shop, M&R Engineering has grown into a large Davenport and CNC Machine Shop.  Over the years, M&R Engineering built an outstanding reputation for excellence and innovation in custom machined parts.  Delivering high-performing custom machined metal parts means starting with quality metal machining materials. That’s why M&R Engineering has fast and economical access to large quantities of today’s best materials, allowing us to meet short and long-run orders quickly and cost efficiently. We are AS9100 and ISO 9001 certified, and our materials come from suppliers who share our commitment to quality.  We have vast experience in machining parts including brass, copper, aluminum, cold rolled steel, stainless steel, titanium, and other metal materials.  

Why choose high precision CNC machining of metal over 3D printing?

High precision CNC machining is a subtractive process in comparison to the 3D additive printing process. Currently, 3D printing has limitations when it comes to metal material selection. Most popular materials used in 3D printing are plastics. High precision metal CNC milling and CNC turning also offer 15 times more accuracy of 0.001 inches compared to 0.016 inches in 3D printing. Metal parts manufactured by 3D printing are currently undergoing substantial testing for strength and usability. 3D printing is a quieter, less messy process that requires less programming and operating resources and is a good solution for odd-shaped low tolerance low volume prototyping when material selection is not important. However, when it comes to high precision, high tolerance metal parts, high precision CNC milling and high precision CNC turning are the best options by far.
