CNC Turning Tolerance

If not otherwise specified on the technical drawing, all parts will be machined to ISO 2768 tolerance standards below. Generally, you can choose ISO 2768-m, ISO 2768-f or specify much tighter tolerances in your 2D technical drawings.

Limits for nominal lengths	ISO 2768-m	ISO 2768-f
0.5mm to 3mm	±0.1mm	±0.05mm
Over 3mm to 6mm	±0.1mm	±0.05mm
Over 6mm to 30mm	±0.2mm	±0.1mm
Over 30mm to 120mm	±0.3mm	±0.15mm
Over 120mm to 400mm	±0.5mm	±0.2mm
Over 400mm to 1000mm	±0.8mm	±0.3mm
Over 1000mm to 2000mm	±1.2mm	±0.5mm

Roughness and threads

Standard order surface finish shall be referred to as As Machined and requires a ~125 RA µin (3.2 RA µm) finish. Minor tool marks visible on the part are acceptable. Or you can specify more tighter roughness in your 2D technical drawings.

All sharp edges and burrs will be removed. If any form of threads (internal or external), any non-standard tolerances or any non-standard surface finish are required, these must be clearly indicated in a 2D technical drawing.

CNC Turning Surface Finishes

Surface finishes are crucial for achieving the desired functional or aesthetic quality of CNC machined components. At SogaWorks, we offer a spectrum of surface finishes to enhance your parts’ function by improving hardness, roughness, corrosion and heat resistance.

Grow a thickness oxide layer ranging from 0.0001 to 0.001 inches to protect and color aluminum CNC machined parts for corrosion resistance and aesthetics.

Anodizing Type II

Create a thicker layer ranging from 0.001 to 0.004 inches. it is ideal for where hardness and wear resistance are crucial.

Anodizing Type III

Preserve or enhance the electrical conductivity of the aluminum parts while still providing the benefits of traditional type II.

Conductive Anodizing Type II

Cover a part with a thin layer of metal by electrochemical deposition for function, decoration or corrosion resistance.

Electroplating

Apply a protective coating of zinc to steel, iron, and copper objects to prevent corrosion.

Galvanizing

Apply a protective or functional coating to surfaces. It involves the application of liquid paint and then undergoes a curing process to solidify the paint film.

Painting

Apply a protective and decorative coating to materials, primarily metals. It involves applying a dry powder onto a surface, which is then applied electrostatically and cured under heat or UV light.

Powder Coating

Spray silica sand to the surface of the workpiece using compressed air to clean, smooth, or texture surfaces, providing a desired finish for functional or aesthetic purposes.

Sand Blasting

Apply images, patterns, or text to surfaces.

Silk Screen

A conversion coating applied to ferrous metals to provide a thin, protective layer of black iron oxide.

Black Oxide

Use abrasive belts or roller brushes to refine and improve the surface quality of components.

Brushing

Selectively remove material from the surface, resulting in a smooth, polished, and often corrosion-resistant finish.

Electropolishing

How Does CNC Turning Works?

CNC turning is a subtractive manufacturing process that employs computer-controlled lathes to accurately shape materials into cylindrical components. The process begins with designing the part using CAD software, which is then translated into instructions for the CNC machine through CAM software. During the setup phase, the appropriate cutting tools are installed, and a cylindrical workpiece is secured in the machine’s chuck, which holds and rotates the material.

As the machine operates, the workpiece spins at high speeds while the cutting tools traverse along various axes, carving and shaping the material according to the programmed specifications. This stage includes operations such as facing, threading, knurling, and drilling. To prevent overheating and remove debris, a coolant is typically applied.

Once machining is complete, the part may undergo additional finishing processes, such as sand blasting or polishing. The final step involves a comprehensive inspection to ensure that the part adheres to all required dimensions and tolerances.
