We offer turning of round bar stock in
Aluminum,
Cold Rolled Steel and
Stainless Steel.
Round bar stock comes in 12 - 20-foot lengths and is cut to size on a band saw before entering the lathe.
• Cold Rolled Steel Round Stock
If you require CNC Turning of a material other than Aluminum, Cold Rolled Steel and Stainless Steel, contact us as we can source a wide variety of materials.
At ProtoSpace, we are able to turn your parts and components within 2-3 days. (Lead times may increase for larger jobs, or orders that include non-stock materials. For more information, contact us).
Work Envelope
Work Envelope for Internal Tooling
ProtoSpace utilizes an 8" diameter chuck with a 2" spindle bore that spins at 4,800 RPM, which is designed to hold round stock of almost any material.
To find out for sure if your part can be made, please contact us with any questions you may have.
The largest item we can turn is defined by the machine work envelope: Bar Stock: 8" x 17.5" | 203.20 mm x 444.50 mm
Corner Radius - We are able to use very small tools to make corners with a very small corner radius. Our suggested smallest insider corner radius would be no less than 0.032" (0.813mm) - for best economics.
If you need an even smaller corner radius, we stock 0.015" (0.381mm) tools. However, you may encounter depth limitations, material removal rates and increases in tool breakage rates, thus raising the cost of the part. Contact us to discuss your specific needs.
Finishing and Turning Toolmarks – The surface finish of CNC turned parts will have visible toolmarks, due to the spinning motion produced by the CNC lathe's cutter. This is considered a turned finish. If you require a smooth, uniform finish to your part, we recommend choosing a secondary finish such as Vibratory Finish, Media Blasting or Powdercoat.
