What is CNC Turning Service, and How Does It Work?

CNC turning, also known as computer numerical control (CNC) lathe services, is a machining process that uses CNC machines to produce parts. This type of machine tool holds a cylindrical workpiece in a chuck and rotates it with a cutting tool.

The chuck can hold the workpiece tightly, but it still allows for some clearance between the turning axis and its axis of rotation. This leaves an excellent surface finish on the workpiece. You can perform turning on the inside or outside of the workpiece.

CNC turning uses subtractive manufacturing on the CNC lathe and turning center. You can work with a range of materials, such as aluminum, steel, and plastic. You will also need to prepare the G-Code and turning machine, securing the blank stock material in the chuck of the spindle. The chuck will hold the workpiece as the spindle rotates.

As the spindle spins, the CNC turning cutter will move on a linear path (parallel to the axis of rotation), thus removing excess materials. This process also reduces the workpiece diameter to a specified dimension, smoothens it, and yields a highly polished final product.

What is CNC Turning Center? CNC Lathe vs. Turning Center

When it comes to CNC turning, you may wonder whether you need a CNC lathe or a CNC turning center. Both tools are designed for the same purpose—parsing out excess materials for workpieces. However, they have a few differences that can help choose the right one for your requirements.

CNC turning center is a computer-controlled 3, 4, or 5 axis machine with capabilities to drill, turn, mill, and tap. It uses live tools that come complete with a rotary tool turret, multiple turrets, dual spindles, and Y-axis.

On the other hand, the CNC lathe is a simpler form of turning center. It is a 2-axis machine with only one spindle. It comprises a headstock, carriage, bed, and tailstock.

Other differences include:

  • CNC turning centers are more complex than lathes
  • CNC turning centers guarantee high production and versatility than lathes
  • CNC turning centers are slant-bed, while CNC Lathes are flat-bed types.

CNC turning centers come with full protective enclosures to keep coolant and chips from splashing the machine. The lathe is only partially enclosed.

Types of CNC Turning Operations

There are several types of CNC turning operations, including boring, drilling, plunging, parting, hard turning, facing, reaming, boring, thread milling, knurling, taper turning, and grooving. Here is a breakdown of these processes:

  • Tapered Turning. This type of turning is used to produce tapered components. It uses special tools made for this purpose—tapered end mills, hobs, and contouring cutters. It is ideal for producing cylindrical parts with increasing diameters.
  • Hard Turning. This is used to create products with precise dimensions and surfaces. It gives a high degree of accuracy, smoothness, and hardness. It works best with Rockwell C hardness above 45, usually after pre-heating.
  • Spherical Generation. This feature is used to create components with a tapered or cylindrical external surface. It is ideal for components with tapers, flat parts, and taper-less parting face, taper turning, and taper milling.
  • This operation creates flat surfaces by facing off the end of workpieces. It creates deep grooves on the surface of pieces.
  • This feature is critical for machining a workpiece to its center.
  • This works just like parting but it produces grooves and steps of various depths and widths on the surface of the workpiece.
  • This involves the removal of material on the surface of workpieces for creating holes using drill bits held in the tailstock or turret.
  • This is used to enlarge or smoothen an existing hole.
  • This feature is used to make internal threads on products.
  • This is also called the micro-milling process because it creates fine lines on the surface of workpieces for decorative purposes or to improve product grip. It uses specially shaped cutters with relief angles (between 11 and 19 degrees). They are ideal for creating patterns or knurls.
  • This is a process used to enlarge or create a uniform bore by removing excess material from holes. It is also called corrective boring since it corrects machined errors.
  • Polygonal Turning. This type of operation uses an end mill to create the workpieces final geometry. It is ideal for creating curved, slanted surfaces and contours on cylindrical parts.

CNC Turning Materials

The CNC turning center can handle a wide range of materials, including aluminum, brass, plastics, stainless steel, hardened steel, tool steels, and some non-ferrous metals.

Materials must be CNC programmable for efficient workpiece processing. However, you will need different lathes for turning wood and metal. Additionally, plastics such as ABS, Polycarbonate, nylon, POM, and ABS are turned in using special lathes.

CNC Turning Services and Parts - Applications

CNC Turning has many applications and services associated with it. Some of them include:

  • CNC Turning Services

Manufacturers and machine shops use CNC turning to produce parts and components for automobiles, aerospace, furniture making, medical tools, firearms, watches and clocks, oil rigs, satellite equipment, metalworking machines/tools, printing presses/machines.

  • This service uses paints of various colors to create the desired appearance of the product. It also forms a protective layer that prevents corrosion and damage from chemicals or elements in the environment.
  • Heat Treatment. This service offers a wide range of thermal treatment options, including tempering, hardening, annealing, normalizing, and stress-relieving. It helps with improving the hardness and wear resistance levels while at the same time balancing better ductility and toughness.
  • Sand Blasting. This service is used to produce a roughened surface on the metal part by blasting it with glass beads or other abrasive material. It can be used to remove coatings and paint, which provides improved adhesion for new coats of paint or other coating materials.
  • Laser Marking. This process uses lasers or bright lights to mark the product. It can be used to produce visible marks, copy a machine-readable code, or etch characters onto the surface of the metal part.
  • Acid Etching. This service provides an even coloration and uniformity across all cases because it does not require masks as other processes such as engraving and stamping do.
  • This process is used to remove any residual contaminants from the metal part by exposing it to an alkaline solution. It ensures better adhesion of primer and paint coatings, which extends the life of these materials.
  • This service uses chemical or electrochemical methods to deposit a metal on the CNC turning part. Electroplating is used for decorative purposes, corrosion prevention, and wear resistance purposes.
  • The anodizing process is used to create a porous surface that ensures improved adhesion of oil and paint on the metal part. It also forms an electrically insulating layer that prevents corrosion and increases resistance to chemical reactions.
  • Chrome Plating. This service provides greater protection against corrosion and wears due to its shiny, reflective nature. However, it is not commonly used on metal parts because it requires expensive equipment, materials, and chemicals.
  • Powder Coating. This service provides a protective layer that is resistant to chemicals, weathering, and abrasion. It has high humidity resistance since the particles are thermally fused. It creates a finish that is tougher than your conventional paint. However, it is not suitable for metal parts with small or intricate details because it can spread through these gaps. It is ideal for bicycle parts, household appliances, drum hardware, automobile, and other aluminum extrusions.
  • Black Oxide. This service is used to produce a matte black color on the metal part that offers protection from oxidation and corrosion. It can even be used on stainless steel, cast iron, and other metals with low carbon content.
