Surface Finishing for CNC Turning

Precision-turned parts benefit from specialized surface treatments that enhance strength, durability, and overall performance. These treatments are ideal for optimizing the functionality of shafts, bushings, and cylindrical components.

As-Milled

The quickest and most economical option, leaving visible tool marks and potentially sharp edges or burrs. Surface roughness is approximately 125 µin Ra, and burrs can be removed upon request.

Hard Chrome Plating

A thick chromium coating that boosts hardness, wear resistance, and durability. Perfect for high-stress parts like shafts and pistons.

Nickel Plating

A thin, electroplated nickel layer that enhances wear and corrosion resistance. Provides a bright, attractive finish for functional parts.

Black Oxide

A chemical treatment that creates a dark, matte black surface on steel parts. Offers mild corrosion resistance and reduces light reflection.

Polished Finish

A smooth, glossy finish achieved by mechanical buffing. Ideal for decorative parts requiring enhanced shine and low roughness.

Brushed Finish

A linear, satin-like texture created using abrasive belts or brushes. It reduces minor imperfections and offers a clean, decorative appearance.

Custom

Need a specific finish? Submit an RFQ, and we’ll work with you to find a tailored solution for your project.

Bead Blast

Creates a smooth, matte finish by media-blasting, typically with glass beads, offering an improved aesthetic and uniform surface texture.

Design Guidelines for CNC Turning

Optimize your designs for manufacturability with our helpful guidelines. Our experts provide feedback on your custom machined part for the best results in CNC Turning.

Features	Recommended size
Radii	Minimum internal radius: 0.5 mm recommended. Larger radii (up to 3 mm or more) improve tool access and reduce stress concentrations.
Threads and Tapped Holes	External and internal threads can be precisely cut. Standard thread sizes from M1.6 and larger are feasible. Ensure a minimum thread length of 1.5 times the diameter for stability.
Minimum Wall Thickness	Minimum wall thickness of 0.8 mm for metals and 1.5 mm for plastics to ensure structural integrity without compromising the machining process.
Text	Engraving should have a minimum character height of 2 mm and a depth of at least 0.5 mm for legibility after machining.
Holes	Minimum hole diameter of 0.5 mm. For deep holes, maintain a diameter-to-depth ratio of 1:10 to avoid tool deflection and ensure hole quality.

Frequently Asked Questions

CNC Turning

What parts can CNC turning make?

CNC turning is used to produce cylindrical and symmetrical parts by rotating the workpiece around its axis while a stationary cutting tool removes material. This process is ideal for creating components such as shafts, pins, rods, bushings, and pulleys. Additionally, CNC turning is effective for creating external threads, internal boreholes, and complex contours on cylindrical surfaces. The precision of this method ensures tight tolerances and smooth finishes, making it perfect for parts that require exact fits, such as those found in automotive, aerospace, and manufacturing machinery.
What materials can be machined using CNC turning?

CNC turning is compatible with a broad spectrum of materials, including metals like aluminum, stainless steel, brass, and titanium, as well as plastics such as ABS, Nylon, and Acetal. The choice of material depends on the specific requirements of the part, including strength, durability, and environmental resistance. Each material presents unique machining challenges and benefits, which skilled operators manage to ensure optimal results.
Can you produce plastic turned parts?

Yes, CNC turning is capable of producing plastic parts, with a wide variety of plastics commonly being turned on CNC lathes. Materials such as ABS, Polycarbonate, PTFE (Teflon), Nylon, and Acetal are well-suited for this process. Each material offers unique properties: for example, Nylon is known for its strength and resistance to wear, while Acetal provides excellent machinability and dimensional stability. Turning plastics requires careful control of cutting speeds and tool selection to avoid melting or deformation, ensuring high-quality and precise parts for a variety of applications.
What’s the difference between CNC milling and CNC turning?

CNC milling and CNC turning are both subtractive manufacturing processes, but they differ in the way material is removed. In CNC milling, the workpiece remains stationary while the cutting tool moves along multiple axes to shape the material. This method is ideal for producing complex parts with intricate features like slots, holes, and contours. On the other hand, CNC turning involves rotating the workpiece while the cutting tool remains stationary, making it best suited for cylindrical parts such as shafts and rings. While milling is better for complex geometries, turning is typically faster and more efficient for producing round parts.
What is a CNC turning center, and what types of parts can it produce?

A CNC turning center is a highly advanced, computer-controlled machine designed to manufacture cylindrical parts with precision. This versatile machine can produce a wide range of components, such as shafts, pins, screws, bushings, and other intricate parts. CNC turning centers are capable of performing various operations, including facing, turning, threading, grooving, drilling, and even complex contouring. Thanks to its automation, the CNC turning center ensures consistent production quality and efficient handling of both simple and complex parts across a wide range of industries.
