Different Types of CNC Machining Services

One of the most innovative manufacturing options available today is CNC machining services. In a simple definition, it represents a unique engineering process and is popular due to its emphasis on accuracy, precision, and unmatched quality cutting.

If you want to learn more, check this detailed guide on the most popular types of CNC machining Services:

 

What Does CNC Machining Stand for?

 

‘CNC’ is a wide-ranging term that defines an array of subtractive manufacturing processes where the material is removed from a stock workpiece or bar to produce a finished part. This computerized process is used in manufacturing where code controls and pre-programmed software dictate the production tools’ movement.

Typically, this stunning process is applied in controlling an extensive collection of machinery. The machinery can include grinders, mills, routers, and lathes. The machining method is particularly effective because it doesn’t necessarily need a human to work on it and performs an accurate cutting process!

 

What CNC Machining Processes Are Involved?

 

The CNC machining method utilizes a wide range of technologies that turn, mill, drill, or, in some cases, blend all these techniques. Here are the common types of this remarkable service.

 

CNC Turning

 

In simple terms, CNC turning is a distinct process that comprises material bars placed in a chuck and rotated while incorporating a tool into the metal piece to eradicate material until you achieve the shape desired.

Since you get the desired shape through the material removal process, this procedure can also be called subtraction machining.

This process is especially popular for its reliability and affordability hence its common usage for better performance at a minimal cost.

 

 

CNC Milling

 

Ideally, CNC milling is a mechanical but straightforward process that uses a unique rotating tool to cut and remove chips from a workpiece through physical contact. CNC Milling is applied for various functions, such as chamfering, slotting, and threading. This technology produces intricate and complex designs in a single milling center.

CNC milling is a robust process that can be applied to different types of metals like brass, aluminum, and steel, as well as plastics like ABS, POM, HDPE, Nylon, and Polycarbonate, to mention a few.

CNC milling is notably popular due to its unmatched accuracy with tolerance as solid as +/- 0.1 mm. Under this CNC service, you will discover several other sub-types, such as Form Milling, Face Milling, Surface and Profile Milling, and Gear Milling, which usually operate (mill) axially, laterally, or combine the two provisions.

 

Low Volume Manufacturing

 

CNC Drilling

 

Another popular service is CNC drilling. This machining service works in the creation of tubular holes in the workpieces. The CNC drilling method allows for both angular and perpendicular hole drilling.

  • Vertical drilling: This is a simple procedure involving inserting the rotating piece into your material through a standard CNC device.
  • Angular Drilling: Alternatively, the angular drilling process uses specific automated configurations and clamping devices. CNC drilling allows several unique operations, including countersinking, tapping, and reaming.

 

 

Multi-Spindle Machining

 

Finally, this list of CNC machining services includes this remarkably popular cutting process.

Multi-Spindle (CNC-specific) devices comprise multiple spindles positioned in a specified drum.

Ideally, the process starts with the horizontal rotation of the mentioned drum, continually shifting positions, with the ability to perform multiple simultaneous operations. The presence of multiple spindles ensures work is simplified since work is divided among the spindles.

The machining process is a valuable and effective service since it is cheaper and guarantees more efficient than using multiple standard CNC devices.

 

Top Advantages of Using CNC Machining

 

CNC Machining Services is a remarkable process, especially for high and medium volume requirements where accuracy and complexity are vital. CNC machining offers many benefits over other CNC services.

While the list of benefits is somewhat diverse and extensive, there are common advantages of using CNC machining, including enhanced finishes, reduced cycle times, and the completion of multiple features simultaneously, instantly improving accuracy and consistency.

Here are some of the most common benefits users can enjoy:

  1. Improved precision and accuracy
  2. Reduced waste material production. This is due to the enhanced precision
  3. Consistency and rigidity in the finished products
  4. Boosts production times. This usually leads to higher & more quality volumes
  5. Minimized operating and labor-associated costs. This is a benefit resulting from the reduced need for manual laborers.
