Design Guidelines for CNC Turning
Our basic guidelines for CNC turning include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.
| US | Metric | ||
| Maximum Dimensions | Diameter | 3.95 in. | 100.33mm |
| Length | 9 in. | 228.6mm | |
| Minimum Dimensions | Diameter | 0.16 in. | 4.07mm |
| Length | 0.05 in. | 1.27mm | |
| Wall Thickness | 0.020 in. | 0.51mm | |
| Angle | 30° | 30° | |
| Tolerances | +/- 0.005 in. | +/- 0.13mm | |
Additional Notes on CNC Turning Guidelines
- Small features may be allowed, but the diameter in any region should not be less than 0.030 in. (0.76mm).
- Sharp conical points are allowed; angles should be greater than 30 degrees. Walls thinner than 0.020 in. (0.5mm) typically do not survive the machining process.
Design Considerations
- As the turning process applies pressure to the material, weak shapes that may flex can be difficult to machine, such as long thin structures.
- Turning generates a cut surface with fine helical feed marks resulting from the rotation of the part and movement of the cutter – consider specifying a desired surface roughness.
- Bored holes become difficult when the ratio of the depth to diameter is high.
- CNC turning is the only industrial process to choose when making production volumes of concentric shapes or threaded features. And, because of the rigid construction of these machines there is little vibration, which means CNC turning can offer high levels of dimensional accuracy with excellent surface finishes.
- Combine with our other processes, such as CNC machining, EDM, low- volume production, prototype models, and surface treatments etc., to save costs for you while ensuring quality and service.

Types of CNC Turning Processes
There are many types of CNC turning operations for CNC services that can be performed on a live tooling lathe in a CNC turning factory, including Hard turning, Parting, Facing, Boring, Reaming, Taper turning, Drilling, Knurling, Threading, Grooving, etc., comes in varying tools, cost and set-up time.
1. Tapered turning: produce a cylindrical part of which diameter decrease from one end to another.
2. Hard turning: suited for materials with a Rockwell C hardness greater than 45, typically performed after heat treatment.
3. Spherical generation: create a spherical finished surface, turning around a fixed rotary axis.
4. Facing: a turning operation in which the workpiece is machined to its center.
5. Parting: create deep grooves that remove a completed or part-complete component from its parent stock.
6. Grooving: similar to parting, but only cut to a specific depth from outside or inside the workpiece.
7. Drilling: remove materials to drill holes inside a workpiece with drill bits held stationary in the tail stock or tool turret of the lathe. Boring: enlarge or smooth an existing hole.
8. Knurling: cut a serrated pattern onto the surface of the workpiece with a knurling tool to change or enhance the visual effect or hand grip.
9. Reaming: remove a small volume of materials from a drilled hole for highly accurate diameters.
10. Threading: turn standard and non-standard screw threads, which generally means single-point threading.
11. Polygonal turning: non-circular forms of machining operation without interrupting the rotation of the raw material.
Our standard surface finishes
Here is a list of standard surface finishes. For custom surface finishes such as electroplating or polishing, please contact info@elimold.com.
| As-Milled | 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 | Abrasive blasting, more commonly known as sandblasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants. | Grit： #120 | Color： Uniform matte of raw material color |
| 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. | Grit： #120 | Color：r Uniform matte of raw material color |
| Bead Blasting + Anodizing color or clear (type II) | Type II anodizing is mainly used to produce parts with a uniform, aesthetically pleasing surface and provides good corrosion and limited wear resistance. Parts are bead blasted to #120 grit prior to anodizing. | Thickness： 8 – 12 μm (clear), 4 – 8 μm (color) | Color： Black, clear or any RAL code or Pantone number |
| 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. | Thickness： 18 – 72μm | Color： Black or any RAL code or Pantone number. |
| Electropolished | Electropolishing is an electrochemical process used to polish, passivate and deburr metal parts. It is useful to reduce surface roughness. | Color： Natural metal color. | |
| Brushed | Brushed or dull polished metal is metal with a unidirectional satin finish. It is produced by polishing the metal with a 120–180 grit belt or wheel then softening with an 80–120 grit greaseless compound or a medium non-woven abrasive belt or pad. Commonly brushed metals include stainless steel, aluminium and nickel. | Surface roughness： 0.8 – 1.5 μm | Grit： #80-120 |
