Precision CNC & Traditional Machining & Manufacturing Services

With more than 30 years of experience using precision lathes, mills, drills and saws to cut metal, the diversity of products, materials and sizes Blue Grass Manufacturing has made over the years in its machine shop is astounding. We've made parts for a diverse collection of industries from Oil and Gas to Agricultural; Automotive to HVAC; Heavy Construction Equipment to Lighting. We've machined: bar, tube, forgings, castings, and extrusions; mild, stainless and hardened steels; brass, aluminum and plastic to produce high tolerance surfaces at low cost. Our large machine park contains a great variety of Lathes and Mills of all sizes so that we always have the right equipment to do the job and can deliver high throughput with short notice.

Heavy parts, hardened steels and tight tolerance don't scare us. Our skilled machinists think nothing of holding tolerances of ±0.001" (25µm) on a 10” (254mm) diameter part: tolerances so tight we have to control the part temperature during measurement! We can go to tighter tolerances, we can even compensate for dimensional changes during heat treat to deliver tolerance ±0.0004" on parts that grow during the heat treat process, an achievement that requires detailed study and highly knowledgeable engineers. We work hard to understand what you want parts to do, support your engineers during the design process offering considerable engineering support and then develop a production process to deliver exactly what is wanted.

Our 3-axis and 4-axis CNC milling centers are capable of machining parts as large as 35.43" (900 mm) in length, 23.62" (600 mm) in width, and 23.62" (600 mm) in height. Our CNC lathes have a maximum capacity of 21" (533 mm) for part diameter with a maximum length capacity of 30" (762 mm). We have cranes fitted at many of the machines to allow larger parts to be processed efficiently so we can handle heavy parts too!

Additional services include welding, CMM inspection, and assembly, as well as all manner of outsourced processes such as heat treat, plating, grinding, painting and other secondary services sourced through our large network of suppliers. As a turnkey service provider, our capabilities range from single components to complete mechanical assemblies. We are proud to be ISO 9001 certified and employ a Six Sigma black belt on staff. All necessary statistical data required for production part approval processes (PPAP), statistical process control reports (SPC), or other quality documentation can be provided on request.
