CNC Turning Surface Finishes

With a wide selection of surface finishes, Yinchen can help improve the surface qualities of your products. Surface finishes applied to your CNC turned parts aim at improving their appearance, surface hardness and roughness, chemical and corrosion resistance, etc. They also help hide any visible tool marks from areas cut with live tooling. Here are some of your top choices.

image

As Machined

As machined finish leaves the surface straight from the CNC machine, providing a cost-effective option with tool marks.

image

Anodizing

Anodizing increases corrosion resistance and wear properties, while allowing for color dyeing, ideal for aluminum parts.

image

Polishing

Polishing achieves a high gloss finish, reducing surface roughness and enhancing the aesthetic appeal of metals.

image

Sand Blasting

Sand blasting uses pressurized sand or other media to clean and texture the surface, creating a uniform, matte finish.

image

Tumbling

Tumbling smooths and polishes small parts by friction and abrasion in a barrel, offering a consistent but slightly textured finish.

image

Electropolish

Electropolish is a chemical process that smooths and brightens surfaces while improving corrosion resistance.

image

Alodine

Alodine coating provides corrosion protection and improves paint adhesion, mainly used on aluminum surfaces.

image

Heat Treatment

Heat treatment alters the mechanical properties of metal to increase its hardness, strength, or ductility.

image

Brushed Finish

A brushed finish creates a unidirectional satin texture, reducing the visibility of marks and scratches on the surface.

image

Powder Coating

Powder coating applies a thick, wear-resistant layer with excellent color and texture options, suitable for a variety of surfaces.

image

Electroplating

Electroplating bonds a thin metal layer onto parts, improving wear resistance, corrosion resistance, and surface conductivity.

image

Black Oxidize

Black oxidize is a conversion coating for ferrous metals that improves corrosion resistance and minimizes light reflection.

As an lSO 9001 certified company, we machine CNC turning lathe parts to meet tighttolerance requirements. Based on your design, our CNC lattes can reach tolerancesofup to +0.005". Our standard tolerances for CNC milled metals is lS0 2768-m andIS02768-c for plastics. Tolerances forCNC Turning

Description
Maximum PartSize Typically up to 500 mm in diameter and 1500 mm in length, though larger sizes can be accommodated with specific
equipment.
Minimum PartSize As small as 1 mm in diameter, depending on the material and machining setup.
General Tolerances Standard tolerances of ±0.01 mm; tighter tolerances down to ±0.005 mm can be achieved based on the material and
complexity of the part.
Lead Time Standard lead times ranae from 3-7 days for small batches, Expedited services are available, reducing lead time to 24-
48 hours depending on part complexity and material availability.

Design Guidelines CNC Turning Design Guidelines

Recommended Size
Radii Minimum internal radius of 0.5 mm recommended. Larger radi (up to 3 mm or more) can improve tool access and
reduce stress concentrations in the part.
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.
Minumum WallThickness Maintain a minimum wall thickness of 0.8 mm for metals and 1.5 mm for plastics to ensure structural integritywithout compromising the machining process.
Text Engraving should have a minimum character height of 2 mm and a depth of at least 0.5 mm to ensure legibilityafter machining.
Holes Minimum hole diameter of 0.5 mm. For deep holes, maintain a diameter to depth ratio of 1:10 to avoid tooldeflection and ensure hole quality.

Why Choose Us

  • CNC turning produces cylindrical and symmetrical parts around their axis. This process is typically used for manufacturing items like shafts, pins, rods, bushings, and pulleys. It’s also well-suited for creating external threads, internal boreholes, and even complex contours on cylindrical surfaces. The precision of CNC turning allows for tight tolerances and a smooth finish, making it ideal for parts that require exact fits and movements, commonly found in automotive, aerospace, and manufacturing machinery.
  • Yes, CNC turning is versatile enough to handle various materials, including plastics. Plastics commonly turned on CNC lathes include ABS, Polycarbonate, PTFE (Teflon), Nylon, and Acetal. Each material offers different properties; for instance, Nylon is known for its strength and friction resistance, while Acetal provides excellent machinability and dimensional stability. Turning plastics requires precise control of cutting speeds and tool selection to prevent melting or deformation, ensuring the production of high-quality, precise parts suitable for a range of applications.
  • CNC milling and CNC turning are both subtractive manufacturing processes, but they differ in how the material is removed.

    In CNC milling, the workpiece is stationary, and the cutting tool moves across multiple axes to remove material and create the desired shape. This process is ideal for complex parts with various features such as slots, holes, and contours.

    On the other hand, CNC turning involves rotating the workpiece while a stationary cutting tool removes material. This method is best suited for producing cylindrical parts, such as shafts, rings, and bolts. While milling can handle more complex geometries, turning is typically faster and more efficient for producing round parts.
  • A CNC turning center is a computer-controlled machine designed to manufacture cylindrical parts with precision. It is capable of producing a wide range of components, including shafts, pins, screws, bushings, and other intricate parts. Highly versatile, the CNC turning center can perform various operations such as facing, turning, threading, grooving, drilling, and even complex contouring. Its advanced automation allows for consistent production quality and efficient handling of both simple and complex CNC turning parts across different industries.
