What is CNC Turning?

CNC turning is a subtractive machining process that uses a cutting tool to remove material for creating cylindrical parts with different sizes. bars of material are held in a chuck and rotated while a tool is fed to the piece to remove material to create the desired shape. A turret with tooling attached is programmed to move to the bar of raw material and remove material to create the programmed result.

Kaierwo have high-precision CNC Turning machine and excellent engineers with 14 years of experience CNC turning for parts manufacturing, we are proud of the high quality of the CNC turning parts we produce. Experienced quality personnel ensures that customer requirements are met or exceeded at all stages of production in custom industrial processing.

Advantages of CNC Turning

Our CNC turning section is equipped with the latest machines, tooling, and CAD-CAM. This allows us to offer an efficient, cost effective and flexible service. CNC turning offers numerous advantages over traditional manual fabrication methods, including:

1. Quick Turnaround

CNC turning equipment is pre-programmed and allows the equipment to move more quickly than manual machining.

2. Superior precision

Pre-programmed specifications ensure greater precision and reliability.

Variable production sizes.  Faster CNC turning allows for larger scale production with high repeatability. We have been equipped with a high-precision tester, which can also ensure the accuracy of the standard of the parts.

3. Material versatility

CNC turning can be used on a broad range of materials.

4. Enhanced worker safety

CNC turning requires less direct human interaction, thereby reducing risk of injury to workers.

5. Cost-effectiveness

Enhanced speed and reduced labor costs can make CNC turning very affordable in comparison with other manufacturing methods.

We supply precision CNC turning services, ability to meet precision tolerances as light as ±0.005mm (±0.0002 inch)

What Kind Of Materials Can Be CNC Turned?

While potentially any solid, stable material can be turned, we work with hard plastic and metals. Note that some tool steel maybe too hard to cut on a lathe or mill or else will require special treatment and a longer production time. Soft elastomers or plastics may also be impossible to turn since they cannot be held in a fixed position or would change in shape under the pressure of the cutting tool

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.

CNC turning is often used for

Functional prototypes and end-use parts

Parts with cylindrical features

Parts with axial and radial holes, flats, grooves, and slots

CNC turning is often used for
Surface Finish Options for Turned Parts

Surface Finish Options for Turned Parts

Parts that are turned typically have a very smooth surface finish.  The as-machined surface finish of the cylindrical areas will typically be much smoother using the lathe than the mill, so consider this when selecting the machining method for those parts that qualify for either method.  Areas cut with live tooling, such as flats and slots, may have visible tools marks.

Not only can provide high-quality parts machining, but Kaierwo can also finish excellent surface finish, including: as machined, smooth, painting, anodize, bead blasting, oxidation, polishing, powder coating, plating, knurling , brushing, passivation etc.
