Available Operations of Our CNC Turning Services

A variety of other machining operations can be performed on a lathe in addition to turning; these include the following:

Facing​

Facing

The tool is fed radially into the rotating work on one end to create a flat surface on the end

Taper Turning

Taper Turning

Taper turning is a cylindrical turning procedure in which the diameter to be generated is constantly changing. This method is used to produce conical shafts.

Contour Turning

Contour Turning

Instead of feeding the tool along a straight line parallel to the axis of rotation as in turning, the tool follows a contour that is other than straight, thus creating a contoured form in the turned part.

Form Turning

Form Turning

In this operation, sometimes called forming, the tool has a shape that is imparted to the work by plunging the tool radially into the work.

Chamfering

Chamfering

The cutting edge of the tool is used to cut an angle on the corner of the cylinder, forming what is called a “chamfer.”

Cutoff

Cutoff

The tool is fed radially into the rotating work at some location along its length to cut off the end of the part. This operation is sometimes referred to as parting.

Threading

Threading

A pointed tool is fed linearly across the outside surface of the rotating work part in a direction parallel to the axis of rotation at a large effective feed rate, thus creating threads in the cylinder.

Boring

Boring

A single-point tool is fed linearly, parallel to the axis of rotation, on the inside diameter of an existing hole in the part.

Drilling

Drilling

Drilling can be performed on a lathe by feeding the drill into the rotating work along its axis. Reaming can be performed in a similar way.

Knurling

Knurling

This is not a machining operation because it does not involve cutting of material. Instead, it is a metal forming operation used to produce a regular crosshatched pattern on the work surface.

Materials We Work With CNC Turning

CNC Turning Metal

CNC Turning Plastic​

Available Surface Finishes After CNC Turning Services

Surface finishes are applied after turning and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts. Below are the mainstream surface finish types from DEK:

As Machined

As Machined

This is the standard choice, economical and rapid, the parts’ surface will leave visible machining marks. The surface finish is equivalent to 3.2RA μm (125 RA μin).

Polishing Surface Finish

Polishing

Polishing is to make the surface smooth by physical friction processing, it is often used to prevent corrosion and remove oxidation. After polishing, the parts have a smoother and brighter finish.

Beat Blasting Finishing

Bead Blasted

Bead blasting is the process of spraying abrasive on the surface of parts under high pressure, after sandblasting, the metal parts have a satin texture or frosted surface, eliminating the processing marks.

Anodized Parts Anodizing Finish

Anodized

After anodizing, a hard non-conductive ceramic coating will be added on the surface of aluminum parts to improve the wear resistance and retain the metal texture and luster.

Electropolished

Electropolished

Electropolishing is the reverse process of electroplating, which simplifies the metal surface at the micro-level through chemical solution. After electropolishing, metal parts can be more bright and reduce surface roughness.

Black Oxided Parts

Black Oxide

The black oxide is a chemical conversion coating, it is produced by a chemical reaction between iron and oxide salt in black oxide solution. The corrosion resistance of parts can be improved after black oxidation.

Powder Coated

Powder Coated

Powder coating can add a layer of solid and colorful polymer coating on the surface of parts, so as to improve the wear resistance and corrosion resistance.

Spray Painting

Spray Painting

Spray painting is to spray paint on the surface of parts in the air. After painting, the parts have various colors, improve the aesthetic appearance, and make the parts unique, enhance brand awareness.

Other surface finishes are also available. Please click here to learn all surface finish knowledge. Or contact our sales team to get an instant quote.

Standard Tolerance Of Our Precision CNC Turning

The table below summarizes the standard tolerances of the parts produced. Tolerances up to 0.001mm are available upon request

Part size / Dimension Tolerance Angularity
<300 mm ±0.005 mm ± 0.5°
<600 mm ±0.01 mm ± 1.0°
<900 mm ±0.01 mm ± 1.0°

Tightest tolerance: ±0.001 mm tightest tolerances are available to depend on your requirements.
