CNC Turning

CNC Turning

Do you want to create parts and components for your company that are as precise as possible? Since 1976, the experienced technicians at Custom Machine, Inc. have been utilizing a process called CNC turning to take the blueprints for parts and bring them to life. Whether you’re interested in creating a one-piece prototype or a full production run for a specific part, we have the tools and expertise to get it done.

With the CNC machining services from Custom Machine, Inc., you can create metal or plastic pieces that are custom built to meet your needs. Unlike machining done with a traditional lathe, CNC turning allows us to use multiple cutting actions at once, which results in more precise parts and components. We manufacture quality parts that meet industry standards. The parts will also feature a superior finish, and maybe best of all, it won’t take us long at all to fulfill your order and send it to you when we use CNC turning.

At Custom Machine, Inc., we have clients from across the country who have turned to us time and time again for their CNC machining needs. They appreciate the precision that goes into each and every part we make, and they know they’ll be able to get access to their parts quickly when they trust us to make them.

Application Benefits

Rapid Tooling
Because CNC can be applied to virtually any material, it is perfect for rapid tooling, i.e., creating fixtures or molds.
Rapid Prototyping
The range of materials available, low cost per unit, and speed of production makes CNC a great option for prototyping.
Serial Production
High-quality finish, vast material options, and precise tolerances have made CNC lathe turning a favorable technology for serial production parts.

Available Finishes
The finish option with the quickest turnaround. Parts are left with visible tool marks and potentially sharp edges and burrs, which can be removed upon request. Surface finish is comparable to 125 uin Ra finish.
Bead Blast
The part surface is left with a smooth, matte appearance.
Anodized (Type II Or Type III)
Type II creates a corrosion-resistant finish. Parts can be anodized in different colors—clear, black, red, and gold are most common—and is usually associated with aluminum.Type III is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.
Powder Coat
This is a process where powdered paint is sprayed onto a part which is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic.

CNC Turning Tolerances

General Tolerance
Distance Dimensions
For features of size (Length, width, height, diameter) and location (position, concentricity, symmetry) +/- 0.005”.
Orientation and Form Dimensions
0-12" +/- 0.005", Angularity 1/2 degree. For 24" and beyond please consult us.
Edge Condition
Sharp edges will be broken and deburred by default. Critical edges that must be left sharp should be noted and specified on a print.
